CPU Overheating - Please Help

HOLY SH!T 90*C?? What Pentium 4 are you running?? a Engineering sample of a "prescott" core? you overclocked or Overvolted? or you have bad ventilation in your case. Omg.. Cleaning your case, dusting. reapplying thermal paste compound. Recheck the contact with your heatsink and compound you should drop to 60-70 max after that. Otherwise you've got your self a bad chip

On these socket 775 boards, the HSF assembly is often held on by just four push pins which can occasionally pop out allowing the Heat Sink to come up off the CPU which can result in extremely high CPU temperatures.

If I were you, I'd first check for obviousl problems like excessive dust clogging or a CPU fan that has stopped spinning. If everything looks good, remove the HSF assembly, clean and reapply paste and re-install the assembly making sure all four pins get clicked into place to hold it firmly to the CPU.

What heat sink are you running... stock Intel? Check the mounting, it may have come loose.

Then your BIOS is giving you wrong information... I guess.

the heatsink is cool but its on the cpu firmly and i cant run those programs bc my comp freezes bc it gets to hot. As soon as i turn it on its already running at 70 to 80C. The CPU could be bad but ive only had it for 6 months

Just because you have 7 fans in your case doesn't mean you have good airflow through the case, wires obstructing the flow, fans not directed properly can build internal heat instead of removing it.

You want your case fans to work together to pull air through the case or the opposite of cooling occurs a normal case setup for airflow is IN from front and side, and OUT through back, and the top if you're lucky enough to have purchased a case with a top blowhole.

I had serious airflow problem with my case until I got fed up with it and installed 2 120mm blowholes in the top, and 1 120mm side fan blowing straight in on the video cards, removed every 80mm case fan and left the holes open which created a superb airflow through the case and solved all my cooling problems.

Its hard to say sometimes your M/B could be going bad and reporting wrong temps, but first you need to eliminate the obvious and make sure the CPU is making solid contact.

If you put thermal compound on the CPU only then seat the heatsink and remove it, you can see on the bottom of the heatsink the complete CPU contact face area on the bottom of the heatsink.

If the contact area on the bottom of the heatsink is showing complete coverage of the CPU then its safe to remount the heatsink on the CPU but first clean off the heatsink compound with isoprophyl alcohol, apply some fresh compound and reseat the heatsink.




Note: I do see one problem with your setup and thats the 330W P/S I'm pretty sure the NV 6600 alone requires a 350W minimum P/S you may want to check into that, theres a P/S load configuring website link under the Sticky I have posted at the top of the Power Supply Section, you can access that website link and put in the components you're running and it will tell you the P/S wattage you should be running, I usually reccommend 50W more than it says you need for future upgrade leeway.

If your push pin connections are secure you may want to remove the fan and heatsink and clean off the factory thermal pad, purchase some Arctic Silver thermal paste, apply as the directions say and reattach hsf and see if that helps.

I have a 3.2 that was constantly giving me temp warnings, turned out one of the plastic push pins was bad so I bought a hsf that didn't use pins but screws and now I rarely see 45C.
