What could possibly make this thing spin so much?

The noise is terrible and it sounds like a server room :/
 
Uhmm maybe your CPU is really getting very hot? How big is the fan?(80mm?) And how long have you had it? Also is it the stock HSF?
 
The CPU is getting very hot :/ This temperature program tells me 51 degrees (Pentium 4 HT 3.0ghz) - but I have 2 fans (CPU and system) and the side of the computer is off! Also not evening running anything major (Warcraft II) ...

Dunno the sizes - everything is stock.
 
Pentium 4 HT 3.0ghz Stock fan. It's cold outside and the thing is running at 73 degrees idle. :eek:
What to do, what to do....
 
Those small fans do make a lot of noise as they run at very high rpm. I don't think 51 is too bad under load as mine(P4 2.8 HT) also runs quite hot.

Thats def not right! That should only be under very high load. Maybe your HSF is buggered(fan not working is spinning too slowly). What you guys using to monitor temps?

51 is Quite ok imo.

I know it's not right. Everything looks fine. I would know, or rather smell and hear when something is not right. It's spinning like it always did. My best guess is (Dolby you can check it too) that there is a buildup of dust directly under the fan restricting airflow into the fins of the heat sink. Otherwise I should maybe just reapply the thermal agent under the heat sink again. Does the effectiveness of the thermal paste degrade over years? I use the Intel Active Monitor (app in windows) to monitor the temps.
 
I cleaned out the PC. Most of the dust under the fan & on the heatsink has been removed. Running at 56 idle now. Now I must just get my hands on some thermal paste and it should drop the temperature down to the 50's I hope.
 
A rice grain of Arctic Silver 5 on a spanking clean processor and HS will sort it out ;)
 
My PC was new 2 years ago, could barely hear a fan. Last month it kept overheating when I really pushed it and it was noisy. I used a high powered air blower to clean it, lo and behold, I gained 7 degrees colder temperates and it is silent again. I couldn't even see the dust really, but it was there.
 
I've actually just cleaned around my fan ; so much dirt had built up it was scary!

Anyway, now I'm running under 35 degrees on 'almost' idle :P

Far to high on idle IMHO. Unless you run overclocked on standard fan. Mine is running at 44 ATM while browsing and posting. I just use artic silver as heat compound, always remove the standard cr@p.
 
Way too hot!
... mine currently using stock fan and core speed, arctic silver paste --> currently running Canopus ProCoder 2 flat out on an NTSC-to-PAL video conversion @ 56 degrees - idles about 24 degrees... room temp approx. 25 degrees currently.

Good regular cleaning of fan and dust blow-out with a compressor does the trick.
 
Intel Really botched the thermal profile of the P4.

Reseating the heatsink is a good move, put some proper paste on it. Also, if your PC does not have a 12cm extractor fan, you will always have cooling problems, no matter how good your CPU cooler is.

The stock cooler will never be silent, for that you need some 3rd party cooler like those made by Zalman.

I would reseat the cpu with proper thermal glue and a new larger heatsink and larger fan...
 
As has been said: Remove heatsink and clean off any thermal grease still on the heatsink and CPU. Clean out the heatsink with compressed air and reaply the thermal grease. Put the heatsink back on and hope for the best. If you're still a bit worried then remove the side panel off the case and put a desk fan next to your case.

BTW: My AMD X2 6000+ Idles at 22C and loads out at 33C. Thermalright Ultra 120 eXtreme Heatsink.
 
I actually thought you risk damaging a Pentium 4 chip over 70 degrees?
