Upgraded to a GTX 580M in my Alienware M17X R2

Here's my initial video if you want to see it:

Any of your have any experience with these? Mine ran about 85 C the first time I tried Crysis 2... just wanted to know if that was normal for this GF114.

I don't have really any cooling options because I have to use the R2's heatsink, but I didn't know if someone could recommend a fan control software...

BTW, Crysis 2 ran at 1920x1200 on Ultra with DirectX9 flawlessly... I was still downloading the DX11 Patch so I will update when I get it installed after work... I'm expecting at least 70 FPS at 1680x1050

Thanks
