So, I installed a new power supply a couple of days ago. In order to do this, I had to remove the heatsink from the CPU. Well, things didn't seem right so I installed the old one and turned it on, the computer had a 2 second delay and the fan would speed up to what seemed like it's maximum then turn off. So, I waited a day, and now there is no delay in turning it on, and it doesn't run at it's maximum. However, whenever I did even the simplest things, it would start to ramp up. Because of this, I downloaded speed fan and saw the the temperates for the cores at idle were above 50C( http://imgur.com/V3d6P0G ) and just starting skyrim would make them skyrocket ( http://imgur.com/C15AMJk ). Keep in mind, these temps are nearly the same even with my case off my computer. The only thing that I could think of would be to reapply thermal paste, which I've never done. I looked at it, and what I think is the old paste looks old and hard. However, would thermal paste really make that big of a difference? When I used to start skyrim, I could barely hear the fan. Also, I'm not sitting here running a game at these temps, I just turned it on to show you guys, I don't want to take chances.
