Hey guys, I have this PC, which is pretty old. It has P4 2.4Ghz CPU, which has never been touched, along with the rest of the PC, except for the RAM upgrade. For some reason, I dont know if the compounds just dried off..haha, but my CPU heats up to sometimes 64 C, when I'm gaming, when I'm just working on papers, its 54 C. What should I do? clean and reapply the compound on there? any suggestions?

Clean off the old thermal compound with a lint free cloth and some rubbing alcohol and reapply thermal paste. I generally reapply thermal paste about every 2 or 3 years.

Since you are removing the HSF you might as well clean off any dust; which can act like an insulator.

Thank for the reply. As I'm posting this my computer is already at 60C.

You can use the PC immediately after reinstalling everything. It will just take some time for the thermal paste to cure properly. Artic Silver 5 needs about 100 hours of usage (not continuous) for it to cure properly which will probably be about 2C or 3C cooler than when AS5 was initially applied.

For the record, I don't know what the normal temp is for the P4 2.4GHz.

But it might be the nature of the beast.

My second PC is a P4 Northwood 2.8 on an i865 motherboard and it boots up at 50C normally. I only play one game on it (Oblivion) because of the X1650 Pro AGP with 512 DDR2.

My 5 month old X2 runs much cooler, 35C at boot. Can't wait to replace the old Northwood with a cooler running CPU.

You probably will be fine if you just unscrew the fan, and clean it and the heatsink.
A word of caution. If you do decide to remove the hsf, be very carefull. Many people without much experience, pull the chip out, with the hsf.
To prevent this, after loosening the hsf holddowns, give the heat sink several twists, to break the bond that the TIM has with the chip.
Each twist or rotation should only be a degree or two in each direction.
BTW, check all your case fans and psu fans, and clean them @ the same time.
Your chip should idle low 30s, and full load around 40c.

Have you tried just cleaning dust out of the heat-sink? My P4-3.06 was overheating while compressing video a year or so back and clearing out a couple of years of accumulated dust solved that problem.
