Quick test: Cooler Master Sub-Zero – sounds as much as it cools

Not so long ago, Intel showed its Cryo Coolingconcept and as the name suggests, it is about very low temperatures for higher overclocking that ordinary users can take part in. For that, coolers are needed that can reduce the temperature so much, and therefore Intel turned to both Cooler Master and EK where both have created their own interpretations of the same concept.

To achieve such low temperatures, one needs a slightly different cooling solution that has long been bright with its absence, namely peltier elements. Simply explained, it is a plate with two different metals where you let direct current flow through these, which then cools one side by moving the heat to the other side. Both Cooler Master and EK have built these around water cooling where the latter has a loose cooling block, while Cooler Master built its into a closed water cooler.

The model is very similar to a regular closed water cooler, at the same time as it protrudes on some fronts. Among other things, the cooling block itself is significantly larger than usual and this is due to all the electronics that are to be brought in, but above all the Peltier element inside. In addition, the pump is a separate unit and also larger than usual for closed water coolers. The entire package also needs an 8-pin PCI-Express connector to get enough power.

We were asked if we were interested in testing the Masterliquid ML360 Sub-Zero and since it is such a different cooler, we said, as you now notice, yes. And because it is so different, the editors chose to use a different system that can raise the heat level a little more. Thus, it is a much more stripped-down test with only a reference to see how it compares to a traditional air cooler.

The test uses the Intel Core i9-10900K from the Comet Lake generation with a total of ten cores under the hood. The clock frequency on this has been nailed to 5.1 GHz with all cores active at the voltage 1.35 volts. Visually, a very simple graphics card is used that does not emit any noticeable sound. This is because the motherboard lacks image outputs.

Test method

To give as realistic results as possible, the coolers are mounted in a chassis from Fractal Design. The box is also equipped with two 140 mm fans from Noctua, one in the front and one in the rear. All chassis fans rotate at a relatively slow 650-700 RPM.

As this is a very different test, the test method differs from other radiator tests. First of all, the pre-applied cooling paste is used and not the Noctua NT-H1 that the editors usually use. In addition to this, most reference coolers are not offered today as the processor was replaced with a Core i9-10900K in order to really be able to push the cooler to its extreme. To be able to see how the Cooler Master Masterliquid ML360 Sub-Zero compares to a standard air cooler, the editors throw in a Noctua NH-U12A for reference.
