The cold.

Cooler very effective and relatively easy to install. Coupled with two SP120 (Quiet) of the same brand, it's so good job we have a cold feeling close to the tower!
CPU idle temperature: 26 ° C under 100% stress test: 43 ° c.
The ventilos provided does not look too bad and they are replaceable but to avoid making the approximate DIY, then prefer Corsair hardware (which is planned for that matter)
I take it one star because the radiator had a few shots and after searching the web, I found that I was not alone in this case.
At this price, it's a shame to pass up the products with defects! Where quality control is past (and reputation) Corsair?
Small detail: the pump is supplied with SATA.
For those with the install, be sure to download the Corsair Link2 software (not supplied) to be system information (CPU temperature, rpm of ventilos, pump status)
