am getting this POST warning : CPU temperature too high:

mobo : Asus p4pe
cpu : p4 2.4b original intel heatsink
case : Antec 1080 performace plus 3 fans
bios : version 1002 10/30/02 default setting
(had to disable power fan monitoring to avoid getting hardware
monitor failure)
AGP card : ATI aiw 7500

I am a newbee to assembing computers, this was my first try, I just got
all my stuff from newegg yesterdsay and just got done assembing. I
havent overclocked or anything all my bios seetings are default


I am seeing following temp
MB : 23 C
CPU : 75-80 C

My room temprature is pretty low ( i am in my basement, my other
computer pIII works jsut fine in teh same room)
I can hardly do anything as my computer halts within a few mins due to
cpu overheating. I havent been able to install the os on it yet!

I have tried following without any success :

1. reinstalled cpu/heathink to make sure its ok
2. double checked all fans are working ( including cpu fan)
3. update the bios

I have noticed that thermal compund from heat sink has comeout from a
few spots
and is stuck on cpu is that normal ??

I have also tried reducing the fsb to 100 and vcore to 1.5 v but this
thing still
heats upto ~ 80

any clues to what should I do ?????

any help will be greatly appreciated.

you sure your cpu is in good contact with the heatsink? I mean, you should get a few minutes from off to overheat area with bare heatsink contact and no fan. The P4 will do it's thermal management stuff to prevent it from getting above the 80 (slow itself down). Make sure the heatsink isn't caught up on the edge of the socket (they have a groove on the edge that comes near the high edge of the socket). I once put my SK-6 on a P3 backwards like that.

Either your heatsink is not touching the CPU or you have a bad CPU. Once I got a CPU (AMD) that worked in every way except it generated too much heat. Reinstalled the heatsink, no go, replace the CPU, all was well. I would place money on the heatsink being installed wrong here. Never installed a P4 heatsink so I can't give any pointers to avoid problems.

Each time you remove the heatsink, it is suggested for best performance you should remove the old compound and add new paste. That said, I have ran my Athlon XP fine without replacing the paste (and this was generic paste). You should give it a try, it might lower your temps a bit. Also, check to make sure there is nothing but paste between the hsf and the cpu (in your case, the cpu heatspreader, so check for hair, dust, etc). You can easily find out if heat transfer between your cpu and hsf by unplugging your heatsink fan and turning the comp on. Feel your heatsink, and if it gives you the error before the heatsink is that hot (guesstimate here), then there is a heat transfer problem, either the paste or your clip isn't applying enough pressure. However, if the hsf heats up pretty fast, then it might be your fan. Either you attached it wrong (like wrong direction) or it's somehow broken. You can test that by replacing the stock fan with a powerful enough case fan (you might have to hold it there) and see if you can run the comp without a problem. Finally, as PCHPlayer said, it might be a broken chip or mobo sensor. I'm not sure if that mobo uses chip diode or it's own temp sensor

Did you remove that lame excuse of a thermal pad thats attached to the heatsink? You should remove that stupid thing BEFORE you put on thermal paste. I have a P4 1.8A@2.52 o/c'd which idles 36 Celcius and 50 loaded (stock inel heatsink/fan). Also use rubbing alcohol to remove any of the sticky stuff the pad leaves behind. Use a thin layer of paste (i use Artic Silver 3 and a razor blade) on the chip cover plate and a thin layer on the heatsink (not the whole sink just the area which touches the chip cover). With the mobo flat on a table put the sink on top of the chip cover and gently turn the sink back and forth to smear the paste to fill in any air pockets with thermal paste. Jam that fan/mounting bracket back on the heatsink and lock'her down. REMEBER: DO NOT GLOB THERMAL PASTE ON CHIP/HEATSINK!! It only needs a thin layer and too much will act as an insulator (will produce more heat). Try that.

Oh yeah I forgot, it might be because the hsf is warped, in that case you would need to lap it.

thanks a lot everyone for your replies!


I had made a rookie mistake while intalling the cpu.

i had not clamped teh heatsink properly on tehtop of teh cpu. It was loose.

moving the heat sinks sticks in opposite directions clamped the cpu down and it works fine now

Thanks a lot again!
