I have a VisionTek Radeon HD 4870 card that, in recent months, has begun to overheat while at idle, requiring me to manually set the GPU fan speed at 70% or higher (I had thought that the normal ATI Catalyst Control software had a function to automatically speed up/down the fan to prevent overheating, but if it does the feature isn't working).
Any ideas on what might be causing my card to overheat while it's doing nothing?
