This TEC cooler LOOKS so cool … I would love to have one of these. I’ve always been a fan of Thermoelectric (TEC) coolers … but power consumption and condensation have been the main disadvantages. The TEC has an unregulated mode which managed to cool the Ryzen 9 5950X to an astonishing 2 °C core temperature!
Taken from TPU … Der8auer has picked up Intel’s latest TEC cooler, built in conjunction with EKWB, and unceremoniously plopped it right into an AMD Ryzen 9 5950X CPU. Well, not completely unceremoniously – there were many accommodations that had to be made in order to achieve this. For one, as this is a solution designed specifically for Intel CPUs and sockets, Der8auer had to Frankenstein his way through a number of cooling parts to be able to adapt the TEC solution to the AM4 socket. Not only that, but Intel’s TEC requires deep software control for it to work properly – software control which only works with Intel silicon, of course. Der8auer thus had to have a second machine running an Intel 10900K CPU to control the software on the Intel cryo cooler.
All in all, the results were interesting, to say the least. The 16-core, 32-thread Ryzen 9 5950X saw single-core-load CCD temperatures in the 90 °C department with the TEC solution disabled – which promptly dropped down to only 50 °C with the cryo cooler actually operating. With a game load, the 5959X achieved up to 5.050 GHz in single-cores on its automatic boost profile. The entire chip often boosted to 4.8 – 4.9 GHz on all cores at once (with variances between the CCDs) whilst under this cooling solution and workload. With the TEC operating in its unregulated mode – which means, with no considerations for CPU operating temperature and power usage for the cooling process – saw the Ryzen 9 5950X achieving 2 °C core temperature results, and boosted frequencies up to a staggering 5323 MHz on all cores – before crashing. An interesting piece of work which you catch on video after the break; one can rest assured that most PC cooling specialists are already working on their own TEC-based cooling solutions following Intel’s achievement in this field.
