Let’s be honest, for the most part, innovation in the AIO cooler market these days consists more of adding more RGB lighting than anything on the performance side of things. But Cooler Master did recently pair up with Intel and change that up. They introduced the MasterLiquid ML360 Sub-Zero. They added a TEC cooler into the loop to push AIO cooling into the sub-ambient cooling range. If you haven’t heard of a TEC cooler, I wouldn’t blame you. TEC is a shortened version of Thermoelectric Unit and they can also be known as a Peltier cooler. In short, they use electricity to cool and while they are effective they aren’t particularly power efficient which is why fridges and air conditioners use refrigerant-based cooling options. But they have been used for cooling computers before, in fact, Cooler Master themselves have used them with their V10 design that I took a look at 11 years ago . So today I’m going to check out the ML360 Sub-Zero and see how they have incorporated the TEC cooler in with an AIO and step away from our normal cooler testing which is normally on a range of Ryzen CPUs to test this on the Intel 10900K as this is an Intel exclusive cooler.
