CPU keeps hitting 100 Tags: Homebuilt Cases CPUs Systems Last response: March 24, 2010 12:27 AM in Systems Share lmonks94 March 21, 2010 11:57:15 AM Yesterday morning my CPU was running smoothly not even hitting 10 on both cores. I saw so much dust and dirt on the case and fans so I decided to clean all fans. Once I turned PC on later that day, every time I do something or go on a game it seems to lagg and hit 100 on both cores.

If it is not - obvious problem. If it is, we need more info. How did you clean the fans? Did you in any stage take the CPU fan off? | Report abuse lmonks94 March 22, 2010 7:15:19 PM The CPU fan is running. Yeah, I did take the CPU fan off whilst cleaning. I cleaned it using cloth and compressed air can. | Report abuse shortstuff_mt Homebuilt system Master CPUs Authority March 22, 2010 7:18:52 PM If you took the heat sink off during your cleaning you need to install fresh thermal paste. | Report abuse Related ressources SLI temp hitting above 100 C, Normal? - Forum I7-2600 hitting very high temps - Forum Stock i5-3570k hitting 106C; damaged heatsink or faulty CPU ? - Forum Gt 430 hitting 100 c while playing farcary 3 & AC3 - Forum I5 3570k hitting 70C at stock speeds - Forum Ask the community Publish lindley010 March 23, 2010 10:43:51 AM Thermal paste doesnt make a large difference, Not something that would cause massive overheating. Get a Temp monitoring program. Also remove the cpu heatsink again and replace it (to make sure its on properly) | Report abuse shortstuff_mt Homebuilt system Master CPUs Authority March 23, 2010 3:10:27 PM Not using thermal paste will most certainly cause massive overheating.

No offense but you're advice will destroy alot of procs. Always make sure you put new thermal paste.
