I read all of the comments and i'm really upset.
Yea fuck any innovation.
-snipped for space-
Stop beeing so conservative.
Otherwise we would still be in the middle age.
Except that TECs are NOT a new idea. They've been around for novelty/enthusiast computing around 2005-10 (Cooler Master V10, Voltaire Hybrid TEC CPU Cooler, Titan Amanda TEC CPU Cooler, Cool IT's TEC Line, and even one GPU that had a TEC+Blower Hybrid Cooling). Heck, the materials industry has been trying to make TECs work, but short of some major material science breakthrough, it's never going to be more efficient than it was back then. The last major modern TEC cooling solution until now was the Phononic HEX 2.0, but even that didn't really do much better than conventional 120mm or 140mm coolers, while sucking up more power.
Assuming this is a revival of TECs in PC computing other than a few ultra-niche products just to help Intel feel better, I would expect to see EK incorporating TECs into monoblocks to cool entire sections of mobo, along with a 40mm fan or two to keep things dry as possible, as well as an insulated backplate. Also, AIOs probably doing a better job than CM's attempt (and at 360 and 420 rad sizes), and a return to TEC-based GPU cooler concepts (those 3-4 slot behemoths that were TEC+Giant Heatsink+Blower or Fan; often jury-rigged by hardcore OC'ers back then), or a modern 2+2 slot setup; following the Asetek GPU AIO.
That being said, one would have more luck trying to shrink down and modernize phase change coolers for CPU and GPU usage, including making them quieter and easier to integrate into PC cases. And the last time those were done, it was Thermaltake and Asetek that thought sticking a micro-fridge system into a PC case was a great idea (but it was ungodly loud, required a ton of insulation, and like all modern fridges dumped a sizable amount of heat outside of the case). Then some other company tried a "dry air conditioned PC case" concept that insulated the case and used desiccant to keep humidity under control. The closest remaining I can still think of are
these rather expensive phase change coolers compatible with most modern CPUs, but those have to be modded to the bottom of a case, ruining most aesthetics.
