Extreme overclockers are always looking for bleeding-edge ways to get e very once from their hardware. They use powerful fans, extensive water-cooling setups, and even thermoelectric plates to make sure their rigs run reliably, even when pushed beyond the intended performance envelope. Recently, hardware manufacturers have been producing "all-in-one" watercooling devices, which are easy to install, and don't require the extensive hassle of traditional modular watercooling systems.

Now, CoolIT has entered the fray with a new type of water-cooling unit with their Freezone CPU Cooler. Unlike traditional systems, the Freezone does not use a radiator, but uses a proprietary "chiller", which uses multiple TECs (peltier plates) to cool the liquid coolant, essentially refrigerating the liquid without a compressor (as expensive phase-change coolers use). This system provides greater thermal efficiency and increased reliability, and is easier to install than full-sized water-cooling kits.
