CoolIT Pure
Quiet-running cooler good for midrange rigs



COOLIT'S $134.99 PURE CPU COOLER is a pre-assembled, all-in-one liquid cooling kit that bolts onto your case and CPU in a few steps, making it relatively easy way to upgrade your rig's cooling system. But while it's quiet and rather affordable, its performance isn't very different from a high-end heat-sink-and-fan combination.
The Pure works on all Intel LGA775 motherboards; AMD boards are also supported, but the instructions only mention Socket AM2 types. Motherboard removal is required for both platforms, which is unfortunate but rather common when installing a high-end cooler these days.
Once you've removed the motherboard, you'll have to install standoffs aroun the CPU socket with the included wrench and attach the Fluid Heat Exchanger (or waterblock) to the CPU. Then, remove your 120mm case fan and attach the cooler's apparatus to your case using the four included scres (if your case has either an 80mm or 92mm fan, it won't work with this cooler), attach a four-pin Molex power connector to the unit to power the fan and pump, and you're done.
Most of the hour-long installatio time was spent removing our motherboard; installing the cooler only took about 15 minutes, and the photo-filled manual was a great help. We were pleased with the Pure's low noise level and attractive appearance, but it didn't cool our Intel Core 2 Duo E6700 test processor much more than the stock Intel heat sink and fan could. (When idle, the CPU ran six degrees cooler; at full load, is was nine degrees.) The 120mm fan doesn't spin up at all as temperatures rise, which hurts cooling performance a bit, but keep the Pure running whisper-quiet.
