You probably will already have noticed it, but the U12S and U14S managed to cool better than the Kraken X40 LCS cooler, especially the U14S crunches down the cooling numbers.

Here's my thought on that, it's the full cover heat block on the Noctua coolers that draw every Watt of heat they can deal with until they run out of capacity. Even tweaked with 16 cores at 100% stress / 1.38V the U14S managed to stay four degrees cooler compared to that Kraken X40 LCS unit, which is a lot in the cooling arena. Now of course, once you go pro with liquid cooling and bigger radiators, the dynamics will shift. But none-the-less this was very impressive to see.
