Radeon 9250 PCI graphics card is overheating, game freezes around >60C. Is there a PCI slot fan that will work with this PCI graphics card? Can I use the 'Arctic Cooling NV Silencer 5 Rev 3'? Or, should I wait till the weather cools off (live in Texas)? Don't want to spend the money on a graphics card with a fan in it if I don't have to.
