    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.


    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!!


    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?

    k so i got my pc to work ... all u got to do is put in a ****load of silver thermal compound like have a nice layer on the cpu and then make a line down the middle n also add some to the heatsink, then make sure u "secure" the heatsink/fan on the cpu just tighten the screws just enough (like as soon as u feel it getting tight stop) ... remember its important to have alot of silver crap on it not to much but just enough (maybe make 2 layers+) ... let me know what happens

    Your only supposed to use like 1 bb of thermal compound.

    I don't know if its just me but this thread is turning into a chaotic discussion. First of all many people are giving tottaly wrong and potentially life threatening advice here. I don't understand why anyone would advise somebody to place their fingers on the processor while you turn on the computer. If one doesn't understand how a processor works, and the amount of time it takes to heat up without a heatsink, you should not post this kind of advice. Just so that you guys know, when you turn on a computer without a heatsink, this could cause the processor to severely overheat and break. Never under any circumstances is one to place their fingers on the processor bare. Now to get onto the purpose of this thread. The person who posted here, posted about a problem that he experienced after he reapplied the thermal paste. The first thing one should do after your first application of thermal paste, is to remove the heatsink that you just reapplied the paste to and check if it makes contact with the processor. Next the motherboard isn't socket 519 as someone here mentioned, it is Socket LGA 775. The processor can only be placed in one direction, or else the socket doesn't lock down properly. Please take the following steps in properly reapplying thermal paste on your processor:
    1. Remove the heatsink and the processor
    2. Clean both the heatsink and the processor with Alcohol until the old paste is gone.
    3. Repeat step 2 one more time to make sure that you get all of it off.
    4. Reapply about (1/2 grain rice) of paste on the processor.
    5. Place the heatsink on top, without removing it, slowly twist around in a 90 degree angle (clockwise and counterclockwise).
    6. Screw the heatsink in place, and make sure that it is screwed in properly

    NOTE: Unless you damaged your processor by following what some users posted here, you should be able to boot your computer once again without any temperature issues.

    EDIT: Watch the language here on these forums. There is no need for profanity.

    hmm i don't know. i was google ing and found that alot of people seem to have severly overheating pentium 4's...

    It could be, since it is a Prescott core, they even tend to run up into the high 60s. However it should not under any circumstances boot up to such a high temperature, unless the heatsink is not set properly on the processor, or the thermal paste is not applied in a proper way.

    Weird problem, Does the monitor light turn green when u initiall turn on computer.

    If soo, then all seems right. I have a feeling the heatsink is not touching the cpu properly. Thermal paste is only used to cover gaps that are not touching heatsink. Nothing else, it will not lower temps or anything. Thats all jargon. Honestly don't even apply the paste, just clean both seat cpu correctly be carefully with the pins. Then take out your mobo battery turn off mobo switch and take out power cord.

    Then put batter back in and turn mobo switch on and put in cable. Now fire her up, and press DELETE key to get into BIOS. At this point I think your problem is gone.

    Tweakboy, you are completely wrong about not applying thermal paste, and that it doesn't make a difference. Different types of thermal pastes exhibit different properties. Arctic Silver 5 vs. Normal Thermal Paste for example. The normal thermal paste would be much less efficient, since it requires more to be used, and therefore it does not lower the temperatures as effectively as arctic silver 5 would. I suggest checking your sources, and looking at some reviews of different kinds of thermal pastes, before posting false information here.
    NOTE: When one does not apply any thermal paste, the micro gaps between the heatsink and the processor are not filled, and therefore it will not make proper contact which in turn leads to overheating/system malfunction.
    EDIT: Thermal paste does lower temperature, and its not all jargon, check your sources.

    yeah but hes still running his Q6600 at 3.7ghz, says his system specs

    The point is that he would not even be able to run his computer at stock, if there were no thermal paste applied between the heatsink and processor. Maybe he didn't build that computer who knows.
