CoolIT PURE CPU Cooler Review

E4600 Temperature Testing

Idle Temperatures


When it comes to idle temperatures, water cooling has a significant advantage over conventional air cooling solutions. The PURE easily beats the Ultima 90 and even ties the Copper Ninja for ultra low temperature. Unfortunately, the Swiftech H20-120 is more efficient. This is mainly due to the fact that pure water was used, which while more thermally efficient than the fluids used in the PURE do require “top ups” from time to time.


Average Load Temperatures


Unfortunately, this is where the sub 1GPM pump and lower speed fan of the PURE starts to handicap its abilities to cool down the hot dual processor. However, one thing should be pointed out before you draw any conclusions: the fan which was used on the Asetek and Swiftech was extremely loud. It is so loud at 12v the icon Swiftech uses to describe it is an iconographic head wearing ear protection! The PURE may not be the most efficient but for the low noise it produces it certainly isn’t that bad.
