EK Water Blocks has always been a liquid cooling specialist, but could be working on a thermoelectric cooling system, better known as the Peltier cell. This is Linus’ latest video. Tech Tips, showing a lightning-fast gaming PC with a Core i9 – 10900 K overclocked to 5.4 GHz.

To achieve and maintain such performance and frequency, Linus has used an unprecedented w aterblock by EK Water Blocks , but has “blacked out” another key part of the system could be a Peltier cell. The waterblock looks like a large block with the EK logo in the center and according to the youtuber it is one of the heaviest he has had his hands on in some time. You also see several cables sticking out of the block, including what looks like a PCIe power connector.

Peltier cell cooling systems are nothing new, but their use is rare as they require a lot of energy to work and have other possible drawbacks : they are therefore very effective for dissipating heat from the CPU, but not exactly “user friendly”. Perhaps it’s no coincidence that, CPU overclocking aside, Linus used a power supply from 1600 W for PC.

The Peltier cell is based on the Peltier effect , a thermoelectric phenomenon in which an electric current flowing between two different metals in contact (Peltier junction) produces a heat transfer . In this way the heat moves from the surface in contact with the CPU to the opposite one that interfaces with the heatsink. For now there are no confirmations from EKWB, so it will be interesting to see if the Peltier cell hypothesis turns out to be correct or not.
