Please log in for more thread options On a near zero load CPU, my system is reporting that my CPU (P4 3.2GHz) is running between 75C-99C. After googling what the CPU should be running at I was, needless to say, rather alarmed. The system temperature is 80F (basically, room temperature). I removed the Intel heat sink and bought a Aero HT-101 (rated to handle a 3.6GHz P4). What a bitch to install. I had to take the mobo out and remove the P4 retention module. The bottom of the copper heat sink didn't look too flat so I lapped it mirror smooth using 1500 grit wet/dry sandpaper with mineral spirits on a 1" granite slab. It took about 15 minutes until the bottom was near dead flat. Added a bit (or perhaps more than a bit) of silver thermal paste. I replaced all the flat cables with round cables. Bought a 500W Ultra PSU ($39 after rebate) with dual 800mm fans and added only the cables that I needed. That cleaned up the interior a great deal. Then I added fore and aft 3K RPM CPU fans to push/pull air over the fins. I put the system back together and powered it up expecting to see the CPU run below room temperature (that's meant to be humor). Crap! CPU still runs at nearly 100C when I first turn it on then settles down to around 77C after 15 minutes or so. I'm guessing that a sensor on the mobo is bad. Is there an alternate way of determining the CPU temperature? I'm curious to know what the CPU temperature really is. | ||||||||||||||||

Please log in for more thread options I use this great little program for CPU/Motherboard temperature monitoring. Also will keep an eye on your fans and voltages. I have it running in my system tray so I can always see what temperatures I am running at. You will need to check and see if your motherboard is supported and then set it up accordingly. http://mbm.livewiredev.com/ -- Tip www.gotips.net | ||||||||||||||||

Had you previously checked CPU temp (before installing this 'sink, with a different sink? Are there any other owners of this board reporting wrong CPU temp? The board should use the CPU's internal temp sensor so unless there is a bios problem, it should be correct. Towards this end you might try a newer bios, or older if you're running the newest. Otherwise I would suspect the heatsink isn't installed good. P4's heat spreader makes it necessary to use minimal amount of thermal compound- about 2/3 grain of rice applied only in the middle of the core, that will spread out even thinner from the pressure of the 'sink and take a few days and thermal cycles to settle into the normal low temp- but it should be expected under 6C difference after that period compared to first running the system. Ultra PSU are dolled-up generic junk. Don't mean to offend with that comment but rather to state plainly that they are not very good relative to a decent name-brand 400W PSU, let alone 500W. It might be worth about $39 though, suitable enough capacity for a moderate system... just don't expect to get a highly loaded system running from one. | ||||||||||||||||
