The sub-zero number: Intel Core i9-11900K vs. Cooler Master MasterLiquid ML360 Sub-Zero - the impossibility of the dreamed-of possible igorslab | April 3, 2021 The Cooler Master MasterLiquid ML360 Sub-Zero is of course not a real cryo-cooling for really high loads, that is not specified, but it wants to guarantee temperatures that are so low in the partial load range that the highest possible boost clock rates can be run. That's exactly what I tried to find out in a short test, because gaming in particular usually stays below 125 watts on average. However, that already seems a tad too much, but I'll get to that in a moment. The fact is: such an all-in-one water cooling has a certain rarity value and of course the instinct to play always wins. The price of well over 300 euros is only a side note because it will scare off normal customers anyway. Summary and conclusion It's a nice technical gimmick, admittedly. With the MasterLiquid ML360 Sub-Zero, Cooler Master has a very unusual product with a high rarity value and extremely good workmanship at the start, but of course that alone does not save such a project. The cryo cooler also does a decent job up to approx. 100 watts, but then the hour comes for normal compact or custom water coolers, because the waste heat from the CPU and the power loss of the thermoelectric cooling element add up. And unfortunately you notice and hear that, of course next to the extremely loud pump. Well, what do we learn from it? Advertising and hope for a miracle are one thing, unfortunately reality is another. It was an experiment, nothing more. You can hardly get any practical use here in everyday life, even if Intel might see it differently. It's a shame actually. Yeah, nothing different than what I have already posted from before.
