With all the problems and issues Im having with my PC, I also have a strange one, my CPU temperature. It keeps rising in temp, even with the fans on 100%. I really have no idea why. The thermal paste I used is an Artic Silver 5, I have my heatsink and CPU fan working properly, all PC case fans working just fine. I went into the BIOS to check the temp. At first it began at 69 C, then it just kept climing up a degree every 5 seconds. Even with the fans at 100%, it still kept climbing up to 80 C, which is unusual since I have no programs running, no graphics card installed or anything else. The cable management in my case is a bit messy but I've managed to hide most of the cables in the back and leave room for the fans to blow properly. Could it be a dust issue? I just checked inside and some dust has managed to accumulate. What can I do? It's very unusual for the CPU temp to rise above 80 C when it's not even running any program. Should I get a new heatsink, even though the one I have is an aftermarket Cooler Master? Or does the issue lie somewhere else?
