I tried overclocking to get better performance out of Crysis. It worked for awhile, but then I started getting graphical glitches so I just put it back to its default clock speed.I do have a CoolIt Elminiator that really kicks *bottom* for cooling, but unfortunately there are a couple of problems for anyone looking into this particular unit:First off, I got a defective unit that made clicking sounds... So I submitted an request to replace it, and got another one, and the fan is shot. So expect non-perfection.Second, it doesn't fit in my case on the side, because my case has an indentation in it, and makes it so I cannot close my cover to my computer case....But for cooling it gets the job done. I'm running a Core 2 Duo, 3ghz and my idle temp is usually 28C
