It's been a long time since we've last heard something about thermoelectric cooling but it seems EK Waterblocks is resurrecting the idea. The idea here is that you transfer heat from one side of the device to the other, with the help of electrical energy. So basically, one side of the device gets really cold while the other side gets really hot.
A new video from Linus Tech Tips shows a gaming PC that features a mysterious new EK cooler that has a couple of cables coming from the block, including a PCIe power cable. This causes speculation that this may be a peltier cooler.
The cooler was largely censored but we can see a number of cables coming off the block including a PCI-E power cable which helps the suggestion that the cooler is a thermoelectric cooling device (TEC) utilizing the Peltier effect to transfer heat from the CPU. Thermoelectric coolers require significant power to run with the EK cooler in question being used in a 1600w power supply system.
