I think you might be right about the CPU. I checked my temps, and they are steadily higher than they once were. The CPU used to idle around 44 C, but now idles around 56 C. I removed the hsf and found that the thermal pad that came with the retail heatsink is absolute crap. The connection is terrible, and in many places, the thermal pad is no longer touching the CPU core. I think I'll order an aftermarket cooler, and also some Arctic Silver 5. Thanks for the help man.
