"My cpu fan speed is 2250rpm and NB fan speed 6025rpm".....CPU TEMP: 58C NB TEMP: 44C. Your NorthBridge fan is almost 3x faster than your CPU fan so it makes perfect sense that it is cooler. Try a CPU fan with a faster rpm. One other thing you can do is install two fans intake @ front and exhaust @ the back if your case can accomodate it, but you should consider a faster CPU fan first. ____________________________ The greatest risk is not taking one

mjjpb I would perform all of what was recommended 1. re-apply thermal compound per Rocky 2. Install 2nd Fan (opp. direction of other) 3. Ensure PS is correct power per link: http://www.jscustompcs.com/power_supply/ 4. memtest86 and prime95 as recommended. When all else fails, beat the %*#$! out of it!!!

Hello everyone, thanks for the great advice. Heres what I have done: I ran prime 95 and it ran fine, my cpu went upto 75c. But it did not crash, which has to be good. No lockup/freezing, no restart etc. (makes me think the freezing is not the heat). I then checked the heatsink again for heat and its fine, its nicely warm, like a kitten(!?). So I thought I would d/l that sandra monitoring thing I heard someone else mention. I went to mainboard information and according to that my board temp is 41 and my cpu temp is 44. It was during the prime95 test I checked this also and saw the cpu rise to 75c so i know its working, question is: is the bios info telling lies on temp or is the program telling lies? Im pleased I checked this since removing and re-applying compound is a last measure as I do believe I did it properly and very well 7 months ago. (surely if I had done it wrong I would of had problems before now? I did it as per instructions, with a very thin layer and very neat).

firstly all temps come from the bios, its strange that they are showing conflicting results i suggest you run prime95 for a few hours to be sure but anyway it sounds much better.

As Rocky said, the general rule is system temp = room temp + 10C, so your system temp should be roughly 40C. The next general rule is CPU temp (at idle) = system temp + 10C, so your CPU should be roughly 50C. So I'd say you're in the ballpark...of course, lower is always better. Don't forget that the P4 has built-in thermal protection, so it's almost impossible to overheat to the point of failure

Hi people! (again!) Heres what I did: I figured while I was in my pc I would take out the optional gameport supplied with my sound card as I dont use it, then as I finished I got the guts to take off the heatsink and cpu. Well im surprised, most of it seemed to of wiped off (vanished) and it had dust on it etc. So I wiped it all off the cpu core. There was not a consisten layer of compound on the heatsink either, and it had bits of dust etc on it. Then I notiched something else, there was like black pad stuck to it, what I assume was originaly padding supplied as it came, and I thought that stuff had to be removed BEFORE the compound went on... so I peeled it off, and its kinda of like thick tin foil, leaving just nice shiny heatsink metal underneath ready to be cleaned. So I cleaned it all up with nail varnish remover, stuck a nice new thin layer of compound on HS and CPU. Put it all back together, boot up, check temps on 'sandra' and my board is 40c and my cpu is 45c (no stress for it, im only typing this). So I figure thats all good after reading what 'Jam' wrote. In my room its now 25c so the board should ideally be 35 but whats 5?? but my cpu should be 45 and it is! :-)

But even after doing this, I still get random freezing in whatever window im using every so often. I have updated my bios from 1.2 to 2.1 (that was SCARY) and it has not happened since, but if it does the only other option I can see is a format and reinstall! (god no!)

that black pad is called a thermal pad it is used instead of thermal paste but thermal paste is generally thought to be superior, never use a thermal pad and thermal paste together! i use the thermal pad that came with my aero 7 fan and its pretty good 38-42c under normal use. good that youve finally sorted it out remember aslong as you do things properly dont be worried to open things and check them. those temps are pretty normal also as i said the bios can be very wrong so dont be worried about the board temp i suggest a side intake fan if your worried but all looks good 4 you now!

Don't format & reinstall...that is a "last resort" solution & it's not guaranteed to solve your problem. Have you checked for spyware? Tested your RAM? PSU? Have you made any changes (software or hardware) that may have brought this on?

yeah i know all about the first time i updated a bios! its one of those things if youve done it once the next time will be simple and you will think what the hell was i worried about?? the frezzing? well ive just changed my mobo and cpu because of freezing and random errors and bsods also no game would play longer than 5 minutes i ran memtest my memory was fine ran prime95 and got errors after 4 minutes! underlocked the bus by 1 mhz and the games would play! and prime95 would go for about 1 hour 10mins before getting any errors which is still bad! anyway i recommend you run memtest overnight then run prime95 overnight if they all come back ok you can rule out these hardware problems for now possibly a driver issue although using the latest driver can cause its own probelms! basically freezing can be anything! i always stick with the driver that works, anyway run those programs defrag your hard drive run a scandisk on the drive do a disk cleanup 1st! but hopefully this bios update will solve the problem

forgot the spyware isse that jam pointed out go and download adaware6.0 and spybot S&D update them and run them, even windows contains spyware, oh yeah update your anti virus and run it. also go and do an online scan as they found some malware in my memory that my anti virus (pc cillin) didnt, i still say this is better than norton.
