I need some information on modding my X800 XL as high as possible on air. Does anyone have experiance with or know where I can go to get lots of info. I was thinking of maybe putting this heat sync on it. And heat spreaders everywhere. Does anyone know of a better copper heat sync that I could use maybe a 80 mm fan on? and do people just use a Thermal Adhesive to hold it on or is it somehow attached with screews? I'm new to video card modding. Any help would be great.
