hmm that is actually normal......... i really have no idea in that case. Looks like the problems is not isolated to you. It seems alot of pentium 4's are overheating. " Guess what? CPU is Fine. MB is fine... PS is fine. The only thing I did was re-seat the processor and all done. Temperature reading is ok. Thanks anyway. Crisstina Resetting the processor WORKS!! I had same problem... and I too did the resetting of the processor and IT WORKED!!! GREAT TIP!!! Been struggling with this!! THANK YOU!! same problem, reseated and it helped. I also noticed the CPU fan was very close to the power supply fan and they were blowing in opposite directions. So I turned the CPU fan around and now the CPU runs 20 degrees cooler. " thats what i could find... Also how much thermal grease did you put? It should be about the size of a grain of rice or a bb or a small pea or something like that. Also don't mix the thermal compounds. I got this quote too "As processors get older, they do run hotter than when new." perhaps you should just change your CPU? I have no idea if the obove quote is true but i guess it could be. How old is you procesor?
