Now let’s get to the stakes. I have done the assembly quite quickly and was therefore also quickly ready for use. The voltage increases, but so do the temperatures under load. When gaming, the promised 5.3 GHz is reached for the first time – on a maximum of 2 cores, but mostly only one. Games that can use many cores extensively will therefore hardly be able to take much advantage here, because then everything folds down to 5.1 GHz and sometimes even further to the well-known 4.8 GHz allcore. Such a Peltier element not only solves problems, but unfortunately also creates new ones at the same time.
And this is also where the cycle of insanity begins with the full loads, once you do the math. In practice, I measured a whopping 176 watts at the 6+2 pin connection of the cooling at full load, whereby in this case you still have to add the waste heat of the CPU of up to 260 watts, which in total as a 436 watt bomb must then be dissipated by the 360 mm radiator. Even the three fans with a little over 1900 rpm don’t help anymore, the temperature drops very quickly and the CPU throttles.
Let’s now compare different loads and the achieved temperatures in the recommended automatic mode and 100% fan speeds with the temperatures of the conventional 360 AiO from the launch review with controlled fans:
| Workload | Tmin | Tmax | AiO Average |
| Idle (18 to 35 watts) | 15 °C | 31 °C | 35 °C |
| Borderlands 3 Ultra HD (75 Watt) | 35 °C | 52 °C | 49 °C |
| Borderlands 3 WQHD (96 Watt) | 51 °C | 70 °C | 69 °C |
| Borderlands 3 720p (120 watts) | 53 °C | 79 °C | 74 °C |
| Cinebench R23 (260 watts) | 85 °C | 100 °C (throttling) | 89 °C |
Summary and conclusion
It’s a nice technical gimmick, granted. Cooler Master has here with the MasterLiquid ML360 Sub-Zero a very unusual product with high rarity value and extremely good workmanship at the start, but that alone does not save such a project of course. Up to about 100 watts, the Cryo cooler does a passable job, but then it’s time for normal compact or custom water coolers, because the waste heat of the CPU and the power loss of the thermoelectric cooling element add up. And this is unfortunately also noticeable and audible, of course in addition to the extremely loud pump.
However, you can forget about efficiency here anyway, you have to sacrifice that for exclusivity due to the design. But even hoping for the extra boost isn’t really fully covered. The AiO compact water cooling from MSI used for the launch review was the better (and especially quieter) choice on average. And was the CPU at least measurably faster now? Unfortunately, the answer to this must also be no, because the package power was almost always above 100 watts.
Well, what do we learn from this? Advertising and hope for a miracle are one thing, reality unfortunately is another. It was an experiment, nothing more. However, there is hardly any practical benefit to be gained from this in everyday life, even if Intel may see it differently. Too bad, really.
