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.
