I recently changed the processor fan on my PC. Nothing fancy like, the same model, just a bit newer, and a lot less noisy. Since doing this, my processor has been running at some ludicrously high temperatures, and whenever I try to open two tabs on firefox, play any games, hell just have too many windows open the damn thing just turns itelf off. I've tried swapping the fans back round, to no avail. Am I beyond help?
