I just got my Exos2 installed, let me let met tell you it does a great job cooling my PEntium 630 o/c to 3.83Ghz, and my Asus X800XT o/c I am getting load temps of about 44c on my cpu and around 49C on the video card, and I have the X800 running at 580/590 speeds, And the Exos2 is completly silent, only issues is it takes some time getting all the AIR out of the lines
