Often overlooked and often underappreciated, the CPU cooling fan performs one of the most important functions for today's fast, multi-core PCs, keeping disasters at bay by preventing processor meltdowns. For most PCs, operation and failure is separated by a few degrees Celsius, and helping CPUs keep their cool in a wide variety of environments is the not so humble task of a CPU cooling fan. But, in today's commoditized computer parts environment, it is very tempting to cut some corners and buy the cheapest CPU fans on the market, after all a penny saved is a penny earned! But, there is a hidden cost to saving a few bucks here, that cheap CPU fan is responsible for keeping what is often the most expensive component functioning in a PC, and if you have to replace a CPU under warranty, all profit on that system goes right out the window!
Add to that the popularity of over-clocking and it becomes easy to see how a cheap fan can cost big bucks. Calgary based CoolIT Systems has the answer for system builders looking to keep their cool, the PURE CPU Cooler, a Fluid Heat Exchanger that is guaranteed to cool things down.

We installed one of these units on an Intel Quad Core CPU mounted on an Intel Motherboard in an Antec computer case and saw immediate results. Our run of the mill cheapo CPU cooling fan struggled to keep our CPU below 99 degrees Celsius when under heavy use - not a good sign and not good for CPU life. We installed the CoolIT Pure and saw temperatures drop by almost 40 degrees Celsius, even under the most extreme loads. The CoolIT Pure retails for around $99 and uses liquid cooling technology to control temperatures. The unit is exceptionally quite and is just the ticket for over-clocked CPUs.
System builders will find the unit comes as a complete kit and can be used with either AMD's AM2 or Intel 775 CPUs. The unit is a little bulky, yet it is still easy to install in a full size case. The power connector plugs into the power supply and not the motherboard, that eliminates the motherboards ability to control fan speed, but the unit is so quiet and effective that motherboard fan speed control is unnecessary.
