OCIA.net has posted their review of the OCZ XTC Cooler Rev 2

Packaging is straight-forward, and installation instructions are on the back. The revision 2 utilizes the same low-noise blue LEDs that the original cooler used. The main difference here is that the revision 2 now has a two-speed switch incorporated into the cooler's body. The construction of the XTC v2 is a bit lighter than the original due to the use of black brushed aluminum instead of the chrome.
