I have a Radeon HD 7470. It is almost always between 75C-79C. Sometimes it ticks up to 80C, at which point my screens go black for several seconds and all of my program windows move around. This has become more common recently, and it's really frustrating when it happens.

It's set to auto, and I can't find where to set it manually.
