Amazon’s Alexa lets you control a Lamborghini’s air conditioning with just your voice

Amazon is taking a bigger step into cars today by integrating Alexa into Lamborghini’s Huracán EVO, and not just to ask questions or remotely control your home — it’s giving the assistant the ability to control settings inside the car, hands-free. The partnership was originally announced last year as part of Amazon’s push into cars, but the integration goes beyond Alexa’s usual bag of tricks.

Alexa’s integration allows users to control “climate and comfort settings including air conditioning, heater, fan speed, temperature, seat heaters, defroster and air flow direction, as well as lighting,” Lamborghini says. (It can also pull up a screen showing you the car’s torque vectoring and traction control.) Of course, Alexa also has its own suite of skills for interacting with your smart home appliances, playing music and podcasts, and basic navigation.

If Alexa-integration means less time looking at the Huracán EVO’s center console, I think that’s a win for everyone.

The Huracán EVO has some physical controls on the steering wheel and driver side door, but a majority of the car’s features are adjusted through a screen in the center console. Giving Alexa more control over the actual car itself means less time hunting and pecking through menus — “Alexa, I am hot” is apparently enough to get air conditioning going — and more time with eyes actually on the road, which could be a win for safety and convenience.

It’s not like Alexa will be driving your car, but give it time.

The automotive industry’s switch from controls like knobs and dials to entirely touchscreen-based displays has been ongoing, and we even ran a review series examining in-car displays as gadgets a few years ago. Amazon’s tried to help smooth the transition with the Alexa-enabled Echo Auto in the past, but we found the accessory worked best as a simple speakerphone and Bluetooth adapter in our review — tasks that required knowledge of location or a consistent cellular connection did poorly. The Huracán EVO’s implementation of Alexa, with all the benefits of actually having real control over a connected car, might be a better version of the idea.

Amazon and Lamborghini isn’t the only automaker / tech company team-up tackling the problem of built-in car software. Volvo’s Polestar 2 launched in 2020 with Android Automotive built-in and Google Assistant integration for similar control over settings like air conditioning, something that wasn’t part of the old Android Auto. We liked the Polestar’s Google-built software, though much like Lamborghini, it comes with a high price tag.

New Huracán EVOs should have the feature from the jump, but Lamborghini says all existing Huracán EVO customers can be retrofitted with support for Alexa, free-of-charge.

Ring Video Doorbell Pro 2 review: Ring’s best doorbell yet

Ring’s new $249.99 Video Doorbell Pro 2 is the best video doorbell yet from a company that has nearly become a household name for video doorbells. It has an excellent field of view and video quality; plenty of customizable features for notifications and recording zones; and speedy performance, whether that’s sending alerts to your phone or smart speaker when someone rings the bell or pulling up the live feed from the Ring app on a phone. If you can tolerate the price tag, are able to install a wired doorbell at your door, and aren’t put off by Ring’s Neighbors app or police partnerships (both of which you can opt out of), the Video Doorbell Pro 2 is one of the best video doorbells you can get right now.

The new Video Doorbell Pro 2 is Ring’s top-of-the-line model, replacing the original Video Doorbell Pro from 2017. Unlike Ring’s other doorbells, the Pro 2 does not have a battery option; you have to have wiring running to it for power. But because it doesn’t have to house a battery, the Pro 2 is much smaller than Ring’s battery-powered options and has faster response times when you want to pull up the feed on your phone or an Echo Show smart display. It also can work with an existing doorbell chime in your home if you have one.

Despite its higher-than-average price tag, the Pro 2 doesn’t really look all that much more premium than other Ring models. The housing is made entirely of plastic, and there’s a big Ring logo stamped on the bottom. If sleek design is what you’re after, Google’s Nest Hello or the Logitech Circle View Doorbell are better choices.

Ring has added a number of new features this time around, but the most significant change is how the Video Doorbell Pro 2 captures video clips. Unlike the prior model and every other Ring doorbell before it, the Pro 2 shoots 1536 x 1536-pixel square video, which lets you see visitors from top to bottom. It also makes it much easier to see if packages have been left at your doorstep because you can see the ground right in front of the doorbell.

On my doorway, the Pro 2’s wide and tall field of view was able to let me see the entirety of my small porch much better than the older 16:9 format Ring doorbells or others that have a tall but not as wide aspect ratio, like Logitech’s Circle View Doorbell. The Pro 2 captures a sharp and detailed image, complete with HDR for balancing bright skies and visitors’ faces. It also has a dedicated infrared night mode that will come on automatically if the light levels are low enough. The porch light I have at my doorway was sufficient enough to keep the Pro 2 in normal video mode, so I was able to have full-color video captures at night without blinding visitors with a light on the doorbell itself like what happens with the Circle View Doorbell.

Thanks to support for both 2.4GHz and 5GHz Wi-Fi, pulling up the Pro 2’s video feed through the Ring app on my phone is a painless process that just takes a couple of seconds. Likewise, asking an Echo Show to display the feed is quick and easy. The Echo Show and Fire TV devices will even automatically display the feed from the camera whenever the doorbell is rung. Older video doorbells used to take an agonizing amount of time to show their video feeds. I’m glad to see this newest crop is much faster than before.

The Pro 2 also has a new “3D Motion Detection” feature that lets you see the movements of someone on your property even if they are out of frame of the camera. The name oversells what this is doing a bit: the app will show a top-down view of movements represented as colored dots on the map of your home overlaid over the recorded video clip. It’s designed to let you see where someone has been on your property before they show up on the primary camera. But the range for this feature is limited to only 30 feet — that’s about enough to reach a third of the way down my driveway — and while it’s a neat demo of technology, I didn’t find much utility in it.

The Video Doorbell Pro 2 shows more of my front porch than other doorbells. The new 3D Motion Detection feature provides the bird’s-eye view of movement on my property, seen in the right image.

The other thing I didn’t find much use for is the Alexa Greetings feature, which lets you have Alexa answer the door through the Ring doorbell if you don’t get to it within a set amount of time.

There are two reasons I didn’t really like this feature. One is since we’re still spending the majority of our time home due to the pandemic, I don’t really need someone else to answer the door for me — I’m always there. The other is the idea of having Amazon’s Alexa robot speak to a visitor in my place. Alexa can ask couriers to leave a package in a particular place you specify or record a message from other visitors that will be sent to your phone. In my tests, it works like a typical Alexa interaction, with a slight delay between each prompt.

But in general, it feels a bit off-putting and rude to force visitors to interact with an unexpected robot. I feel the same way about using the two-way audio to talk to someone at the door through my phone. While there may certainly be great accessibility use cases for these features, they weren’t helpful for me, and I left them turned off. I think basic package detection and notifications, which other doorbells offer, would be more useful, but Ring doesn’t have any features like that.

The Alexa responses feature requires a subscription to Ring’s Protect plan, which starts at $3 per month and enables other features such as a six-second pre-roll recording for motion alerts, the option to only get alerted when a person is detected, video history for up to 60 days, and the ability to save and share clips. You can use the Ring Video Doorbell Pro 2 without paying for this subscription, but you’ll be limited to motion alerts, live view, two-way talking, and six preset responses if you’re not home. Neither one of Ring’s plans, paid or free, offers continuous 24/7 recording. If that’s something you want, Google’s Nest Hello is a better choice.

The Video Doorbell Pro 2 has a traditional grayscale infrared night mode (right), but if you have enough light, it will fall back to its color feed at night (left).

Since Ring is an Amazon company, the Pro 2 works best and offers the most utility if you have Amazon Echo speakers or smart displays. In addition to the ability to automatically show the feed when the bell is pressed, you can have Echo speakers announce when someone’s at the door so you never miss a visitor. This feature isn’t available with Google Nest smart speakers or displays; again, the Nest Hello would be a better choice if you’re running a Google smart home. (Likewise, if you’re running an Apple HomeKit smart home, the Logitech Circle View Doorbell is a better choice.)

Lastly, I can’t cover a Ring product without mentioning its controversial Neighbors app and police partnerships. The Neighbors app is a separate app that collates crime and safety reports from other Ring owners in your neighborhood. By default, the Neighbors feed is integrated into the Ring app, allowing you to see other posts and share video clips from your camera.

Similarly, the Public Safety feature allows police and other public service agencies to request video clips from your camera to aid in solving crimes. You then have the option to approve or deny the request.

Ring has made it easier to manage these features. Both of them are controlled in the app’s Control Center section, where you can disable the Neighbors feed and block public agencies from requesting clips from your video camera. You can also enable end-to-end encryption, which will disable these features and limit the ability to share video clips with others. But I wish Ring would go even further and disable both of them by default, letting owners decide if they want to opt in or not during setup.

Ring’s portfolio of video doorbells has grown significantly over the past couple of years, and it can be confusing to figure out which one is right for your needs. The Pro 2’s pitch is simple: this is the best video doorbell camera Ring sells, provided you have the ability to hook it up to existing doorbell wiring or run new wiring to it. If you want the best performance and are in Amazon’s Echo ecosystem, the Pro 2 is the doorbell to get.

LG Gram 16 review: Large-yet-lightweight laptop delivers big

(Pocket-lint) – The LG Gram 16 is never going to make sense to some people. For many, a large-screen laptop has to be a super-powered desktop-replacer. And if it’s not, why does it exist?

LG’s Gram series has quietly challenged that view for the last few years. And the LG Gram 16 should make this concept less of a leap for those still struggling. 

The pitch: the LG Gram 16 costs around a grand less than the MacBook Pro 16, but still has a big screen, a colour-rich display and long battery life. Oh, and it weighs 800g less and has a better keyboard, for some tastes at least. 

Suddenly LG’s weirdo huge-but-light Gram laptops don’t sound so strange. Indeed, this 16-inch version is quite the stunning proposition.

Design

  • Dimensions: 313.4 x 215.2 x 16.8mm / Weight: 1.19kg
  • Magnesium alloy casing

Interested now? Let’s start by slapping the LG Gram 16 down to earth with one of the big issues you need to accept. 

While the LG Gram 16 is a nicely made laptop, it doesn’t feel like a four-figures slab of the future when you pick it up. Carry it around like a notepad, give it a light squeeze between thumb and finger, and the base and lid panels will flex a bit. 

Pocket-lint

LG has not made the Gram 16 on a shoestring budget. But large, low-weight body panels come with compromises. And you feel them each time you pick the laptop up like this. 

The LG Gram 16’s casing is magnesium alloy, which is the best material for the job. It’s lighter than aluminium for the same level of strength, and a lot nicer than plastic. Just don’t expect the dense unibody feel plenty of 13-inch laptops at this price level.

The issue is all about feel, not utility. The LG Gram 16’s touchpad doesn’t stop clicking because you lift it by one corner of the base. You can’t stop the internal fans spinning by pressing down on part of the keyboard surround. And, yes, we’ve seen these issues in laptops smaller and heavier than the LG Gram 16. 

Its keyboard panel, the most important of the lot, is pretty rigid – if not immaculately so. A little outer panel flex is only a big issue if you think it is. 

Despite being a new entry in this series, the LG Gram 16 nicks its style from its siblings. This is a very plain, serious-looking laptop that isn’t out to dazzle eyes or fingers with flashy finishes. All panels are matte black with a very light texture similar to a soft-touch finish. 

There’s a kind of confidence to a lifestyle laptop this plain, one that weaves a style out of sharp-cornered keyboard keys and a semi-distinctive font. If anything, LG could actually go plainer on this key typeface, which looks a little close to that of a gaming laptop. 

Pocket-lint

But the aim is pretty clear: the LG Gram 16 is a laptop that can fit in just about anywhere. You can take is anywhere too, as the 1.19kg weight is lower than that of the average 13-inch portable. 

The footprint isn’t tiny, of course, but it couldn’t get all that much smaller considering the 16-inch display has fairly small borders on all four sides. 

Display

  • 16.0-inch LCD panel, 2560 x 1600 resolution
  • 99.1% DCI P3 colour coverage (as tested)
  • Glossy plastic finish

The LG Gram 16’s screen also helps keep the shape sensible, as this is a 16:10 aspect display, one taller than the standard widescreen style. This maxes out the perception of space when you use apps, rather than video. There’s no issue with the quality of the panel either. 

Pocket-lint

Colour depth is truly excellent, matching what you get in a top MacBook Pro. Brightness is strong enough for outdoors use, which is pretty impressive considering the sheer square inch count the LG Gram 16 has to light up. 

Contrast is not the best around, but is still good for an LCD-based screen. And resolution is, well, the one LG should have chosen. It’s at 2560 x 1600 pixels, sitting above Full HD, but a way below 4K. 

The MacBook Pro 16 has a sharper screen still, at 3072 x 1920 pixels. But the LG Gram 16 still adds the crucial pixel density it needs to avoid the obvious pixellation that can happen in a larger display like this. 

If you use a 13-inch laptop at the moment that supersize boost is the first thing you’ll notice. The LG Gram 16 makes it seem so much more like you’re using a monitor that happens to be hooked onto a laptop, rather than a laptop screen. That’s great for dull work apps, even for games.  

However, the actual character of the screen doesn’t quite make the most of the top-quality panel underneath, because of another concession made for size: its plastic screen coating. Plastic is often used in matte finish laptops, to scatter reflections. But this is a glossy screen, telling us weight is the issue here. Glass is the usual choice, but glass isn’t that light. 

The plastic film is also far less rigid than glass, causing reflections to distort at the corners a little. And if there’s meant to be a reflection-busting coating here, it’s not a very good one. There’s also no touchscreen, and the hinge only folds back to around 130 degrees, to stop the thing tumbling off your knees through weight imbalance.

Like the flexy lid and bottom panels, the plastic surface is one you’ll have to suck up for the sake of low weight. But does the LG Gram 16 have a high quality screen with plenty of space that you can use outdoors? Absolutely. 

Keyboard & Touchpad 

  • Textured glass touchpad
  • Two-level backlight
  • 1.65mm key travel

The LG Gram 16’s keyboard fills out the appeal of this laptop for us. We type all day, every day, more or less. Keyboard quality matters, and this is a keyboard made for that sort of work. 

Pocket-lint

Key travel is excellent, and not just if you limit your comparisons to ultra-light laptops. The keyboard plate feels rigid, even if – sure – you can get it to flex slightly under significant finger pressure. And springy resistance offers good feedback with each depress. 

We also like that LG has thinned-down the NUM pad, which lets the main set of keys sit more towards the centre of the laptop. Being shunted too far to the left rarely feels good. Here there’s just a mild lurch leftwards. Think universal healthcare, not a state-led redistribution of all wealth. 

The LG Gram 16 also has a two-level backlight and a fingerprint scanner hidden in the power button, just above the NUM pad. 

Plenty of space in the keyboard plate leaves plenty of room for a giant touchpad. This thing is huge – and you probably can’t appreciate it from photos alone, where it seems in proportion with the rest. 

The LG Gram 16’s touchpad has a smooth glass surface, zero floaty wobble, and an easy-to-depress yet well-defined clicker. It’s on the loud side, but that’s it for negative points to note. 

A larger laptop opens the doors to a different approach to the keyboard. But apparently it doesn’t allow for a better webcam. The LG Gram 16 has the same sort of stogy 720p video call camera we see in most other high-end laptops. 

Pocket-lint

Its speakers aren’t even close to those of the MacBook Pro 16 either. LG uses familiar-sounding drivers with just the tiniest hint of low-frequency output and only moderate max volume. Their tone is pleasant, we could watch a movie using them happily enough, but it would be good to see LG improve this area in future generations. 

The main grilles for the treble drivers also sit on the underside, giving them just a couple of millimetres of clearance provided by the tiny rubber feet. Put the LG Gram 16 on a thick carpet or your bed and the treble is attenuated, although it does seem impossible to block the sound fully, which is good. 

Performance

  • Intel i7-1165G7 processor
  • 16GB LPDDR4X RAM
  • 1TB NVMe SSD

The LG Gram 16 is an Intel Evo laptop. This is a new standard introduced by Intel to make laptops with its processors seem more attractive than those with AMD or Apple CPUs. It’s marketing, but not useless marketing, as it means you know you get standards like Thunderbolt 4, an 11th Gen processor, and at least nine hours of battery life (if the screen is a 1080p one). 

Pocket-lint

Our Gram 16 has Intel’s Core i7-1165G7 CPU, 16GB RAM, and 1TB of very fast SK Hynix SSD storage. 

Some CPU overclockers who design their own water cooling systems will disagree, but we think this is enough to make the LG Gram 16 a viable desktop replacement for the vast majority of people. 

Windows 10 feels great, there’s more than enough power to run apps like Photoshop well. So why would you buy a MacBook Pro 16 with a more power consuming 9th Gen CPU? Or a much heavier Windows laptop with an Intel Core i7-10750H?

The top-end Mac has around 60 per cent additional CPU power, in part because it has an “i9” equivalent processor. A Core i7 alternative made for the more traditional desktop-replacing laptop offers around 20 per cent more power, and these processors are designed to hold max power for longer. Because chunky laptops tend to have fans that can shift more air. 

But if you’re not sure if the LG Gram 16 has enough power or not, and you don’t use apps that make your current laptop slow down during exports, imports – whatever procedures they do – then it probably does have enough to satisfy. 

The LG Gram 16 also gets Intel’s Xe graphics, which is a fantastic addition for a laptop like this. It turns slim laptops from poor gaming machines to at least acceptable ones. GTA V? No problem. The Witcher 3? Sure, even at 1080p if you play with the settings a bit. Alien Isolation runs well at just below Full HD resolution with a mix of Medium and High settings. 

Pocket-lint

Absolutely loads of stuff is playable with Intel Xe graphics, because it gets to the level of separate entry-level gaming hardware from the last generation. And that’s not too shabby: it’s gaming skills you seem to get ‘for free’. If you buy an LG Gram 16 and find games don’t run as well as you hoped, make sure to try them at different resolutions. Intel Xe graphics chips may have a bit of punch to them, but 2560 x 2600 pixels is a bit much to ask in most console-grade titles. 

There’s more good news. The LG Gram 16 is almost silent under all workloads, even if you max out the CPU for half an hour. There is a fan, but it’s barely audible if you play something through the speakers even at 30 per cent volume. This is probably the quietest laptop we’ve reviewed with one of these 11th Gen Core i7 processors. It’s another benefit of all that extra room inside: better airflow. 

Battery Life

  • 80Wh battery – up to 22 hour battery life (claimed)
  • 65W charger

LG doesn’t sacrifice battery life for low weight either. More brownie points for LG’s engineers. The Gram 16 has an 80Wh battery, far larger than the 56Wh standard battery of the Dell XPS 15, if smaller than the more power-hungry (and powerful) 100Wh MacBook Pro 16. 

Pocket-lint

Match that sort of capacity with a processor already fairly light on the battery drain and you are guaranteed good results. The LG Gram 16 lasts roughly 14 hours 30 minutes when streaming video at moderate screen brightness.

LG claims 22 hours, but this is one of those cheeky claims that involves using a benchmark from 2014 – and letting it sit in standby mode half the time.

Still, it’s excellent real-world stamina for light work, and way above the nine hours the Intel Evo”sticker guarantees. That guarantee only applies to a lower screen resolution than you get here too. 

Use it with the display maxed and the CPU pushed to its limits the whole time and the LG Gram 16 will last around three hours and 25 minutes. Which still isn’t bad – a gaming laptop wouldn’t give you a third of that. 

Pocket-lint

Want to know about the LG Gram 16’s connections? There are two Thunderbolt USB-C ports, and one is taken up by the charger while plugged-in. You get two classic USB ports, a microSD slot, a full-size HDMI, and a headphone jack too. So it doesn’t demand you keep a USB adapter handy, and you can plug it right into your TV or a monitor. Bliss. 



Best laptop 2021: Top general and premium notebooks for working from home and more


By Dan Grabham
·

Verdict

It’s a wonder the LG Gram concept hasn’t been nicked more times already. The LG Gram 16 is a large-screen laptop that’s genuinely light enough to carry with you everywhere, every day. 

There are barely any substantive compromises involved. The LG Gram 16 is as powerful as smaller laptops that weigh more, it lasts as long off a charge as some of the best Intel-powered laptops, and the keyboard is no lightweight either.

You don’t get the ultra-dense metallic feel of some of the smaller-screened alternatives at a similar price. And, sure, the Gram 16 uses a low voltage processor designed to minimise heat and save battery life, not for blistering power. However, it has enough of it to work perfectly as a desktop-replacer for most people. 

Sure, a 13-inch laptop is better for some. A more powerful, thicker one will be better for others. But the LG Gram 16 takes some elements from both and, through clever design, makes it work far better than you’d imagine. For the right user it’s a stunning proposition.

Also consider

LG Gram 17

squirrel_widget_176886

Want something even bigger? LG has made a 17-inch Gram for a few years now. All the appeals are the same: low weight, good screen, good keyboard. Battery life is slightly shorter as it has a bigger screen and the same battery capacity. But the choice is all about the screen size you’d prefer. We think 16-inch is a more accommodating size for the masses.

MacBook Pro 16

The 16-inch MacBook Pro isn’t really in the same category if you look right up close. It has a more powerful processor and weighs about 800g extra. Oh, and it costs a grand more. Ouch. However, the MacBook seems a more expensive laptop as it has that amazing Apple build, which feels like perfection. The glossy glass screen finish looks better too, making the most of its similarly brilliant colour depth.

Ice Giant Prosiphon Elite Review: Catch the Biggest Air

Our Verdict

Performing as well as premium air cooling and costing less than expensive 360 AIOs, the IceGiant ProSiphon Elite makes for an interesting alternative for high-end performance builds. Standing tall as a monstrous, monolithic cooling solution with a commanding presence, the IceGiant ProSiphon Elite shows that big air really doesn’t get any bigger than this.

For

  • Retail version designed for HEDT for both Intel and AMD (incl. Threadripper)
  • Great cooling performance
  • Four fans allow for push+pull

Against

  • Huge and heavy
  • Premium price

Features and Specifications

Back in 2019 we were one of the few media outlets to get an early look at the prototype IceGiant ProSiphon, an innovative CPU-cooling behemoth that uses natural convection of warmer and cooler states of coolant to effectively ‘pump’ the energy-rich evaporated vapor through the cooler. The months since have brought us to the final version of the IceGiant ProSiphon Elite, and while it still maintains its massive stature, it is noticeably thinner due to a redesigned condenser, which improves upon the original prototype.

The new and improved IceGiant doesn’t break any records, but it does provide a great alternative for system builders who want big and bold, yet still opt to avoid large AIO liquid cooling. Currently available for order from the IceGiant website, it will soon be available for purchase at MicroCenter retail stores as well as available at e-tailers Amazon and Newegg.

The IceGiant ProSiphon Elite includes mounting hardware to accommodate current processor models for both Intel and AMD, including high-end desktop (HEDT) variants like Intel’s i9 Comet Lake chips and the multi-core behemoths that are AMD’s Threadripper processors. The IceGiant makes use of four 4-pin 120mm cooling fans to allow for push+pull airflow configuration out of the box.

Mounting brackets, backplates and supports are incredibly over-engineered to account for the 2-kilogram (4.42 pounds) mass they must support. In fact, just about everything about the IceGiant feels industrial-grade, down to the syringe of high-performance Thermal Grizzly Kryonaut thermal compound included.

IceGiant covers the ProSiphon Elite with an unprecedented 10-year warranty, which includes the cooling fans.

For those who might have missed our original definition of how the IceGiant ProSiphon Elite thermosiphon cooler differs from a traditional heatpipe cooler, please allow us to gratuitously plagiarize our own coverage of the original ProSiphon Elite Protopype: 

Heatpipe coolers rely on the boiling and evaporation of a liquid (typically distilled water) within each individual heatpipe, which travels up the hollow center of the pipe, begins cooling and then fully condenses further up the cooling tower, while dissipating thermal energy in the process. Once that liquid has fully converted back to liquid form, a sintered wicking material along the heatpipe walls then draws the liquid back down to the base to begin the process once again.

A thermosiphon works on similar principles, as it also requires the boiling, evaporation and condensation of a liquid–in this case, a dielectric fluid. A thermosiphon instead makes use of natural convection of warmer and cooler states of coolant to effectively ‘pump’ the energy-rich evaporated vapor through the cooler. Using large, flat condenser cores, the IceGiant ProSiphon Elite utilizes greater surface area to effectively transfer thermal energy out of the fluid vapor, into the cooling fins and away from the cooler.

(Image credit: Tom’s Hardware)

The primary heat exchanger features three condenser cores, which dissipate heat provided from the evaporator in the cooler’s base. The original ProSiphon prototype featured only two condenser cores, allowing the newer retail version of the cooler to have a thinner overall profile when compared to the original. Retention hardware is engineered into the cooler’s base pedestal, which provides an anchored mount once the cooler is installed.

(Image credit: Tom’s Hardware)

The ProSiphon Elite makes use of four 120mm, 4-pin PWM fans rated up to 2300 RPM for push+pull operation. The front pair push cool, ambient air into the heat exchanger and over the condenser cores, while the rear fans pull the warmed air out and away from the cooler. This provides the IceGiant plenty of fresh air in which to breathe (or rather, cool) freely.

(Image credit: Tom’s Hardware)

The entirety of the IceGiant ProSiphon is made of high-grade aluminum, including the precision-milled pedestal base and mounting contact which is large enough to fully cover an AMD Threadripper CPU. Tension screws are permanently affixed to the primary tension bar on the cooler base, which ultimately adds to your advantage later during the installation process.

(Image credit: Tom’s Hardware)

The base of the ProSiphon Elite is milled perfectly flat; we are unable to see any residual light peeking beneath the face of a steel rule.

(Image credit: Tom’s Hardware)

The thermal paste contact patch from our i9-10850k is dwarfed by the untouched backdrop of clean, remaining aluminum of the mounting base.

(Image credit: Tom’s Hardware)

By comparison, the thermal compound patch from our Threadripper 2990WX consumes the entire canvas of the cooler base.

(Image credit: Tom’s Hardware)

Remember those tidbits about the rugged mounting hardware and the tension screws mounted into the cooler base?  Once the backplate and brackets are secured, the cooler base centers itself neatly into position atop the CPU, which aligns the tension screws with their sockets. Both Intel and AMD/Threadripper mounts benefit from this design.

To secure the IceGiant ProSiphon Elite, the front fans are removed and the tension screws torqued into place. Once secure, the front fans are added back and connected via PWM pigtail splitter to the other fans of the cooler to be managed by your favorite fan controller or motherboard header.

(Image credit: Tom’s Hardware)

We’ve tested some large coolers before (including the prototype predecessor to the current IceGiant), yet it always manages to bring a bit of a smirk to our faces seeing such a large piece of cooling hardware in operation. The base height of the IceGiant does allow for relatively tall memory modules to be used. But as usual, check for clearances for specific hardware as needed.
