I've got this problem with my CPU overheating for quite a while now, and I wanted to see if anybody could help me out, i would really appreciate it. Problem: CPU temperature readings on both Asus PC Probe and Motherboard monitor 5 to be at 50+ Celsius at Idle and 80+ Celsius when loaded. Specs: Processor Intel Pentium 4 640, 3.2 GHz, 2MB L2, 800 MHz FSB, Socket LGA775, HT Technology Current CPU fan/heatsing: Stock with stock thermal paste Motherboard: Asus P5GDC Deluxe Intel 915P Chipset for Socket T Ram: OCZ 2GB (2x1024MB) DDR2 Power: Thermaltake Silent Purepower 480W Videocard: ATI Radeon X800XL 256MB 256Bit GDDR3 Casing: Antec Super LanBoy I already have one fan in the front of the case pulling air in, two fans (including the PSU fan) at the back pulling air out, and one side fan pulling air out too. I really don't know the reason why my CPU temp readings are so high. Please, if anyone has any adivice or suggestions, i would truly appreciate it. Thank you VERY much!!

With stock fan/heatsink..for me it just normal.Mine temperature reading is same as yours, before i change to thermaltake copper heatsink with fan + artic silver5 thermal paste.After that my temperature drop about 25+ Celsius. OR Maybe 1.your heatsink didn't attach well with cpu. 2.fan problem. 3.heatsink covered with dusk. 4.not enough thermal paste. hope this info help u. Cheers.

I'd say clean out your pc and add a much better fan that is in there already. not to ffond of stock intel heatsinks. I have a pentium D 930 and I wasn't happy with the stock fan and how my temps were higher then I liekd them to be so I went out and got a nice fan for 30 bucks on newegg and now the temp has dropped by 30c.

The side fan should be blowing in, not out.... The P4 Prescott is known as the "hot potato" & it's common for it to run hot. Are you having heat related problems, or are you just concerned because about the temps? You should verify your readings in the BIOS...don't rely on software. If they're all in agreement, fine...if not, go with the BIOS reading. What BIOS version are you running? I believe the latest is version 1011 & there are also a couple of Beta BIOS available. Temp reading errors are usually corrected in a BIOS update. If all that checks out, double check the HSF installation or look into a possible upgrade like the others suggested

BTW, is it overheating or running hot? There's a difference....

He already ask this question once before and I show him the link to the tomshardware.com where the Pentium 560 having thermal problems with stock hsf and thermalpaste...

Thanks for all the helpful tips and suggestions, i really do appreciate it. To respond to jam's comments, I tried checking the temperature from the BIOS and it was even worst, it read about 61 celsius, and I already updated to the latest BIOS version. And I think my CPU is just running hot, and not overheating, since my computer isn't restarting or freezing because of the hot temperature. I have another little question I was curious about. When I was looking through some other forums about this problem, some said the solution to this would be to change my case to a Thermally Advantaged Chassis, where there's a side air duct on the case. And some said that the solution is to change to a better heatsink and add some Arctic Silver 5. I'm just wondering which way would be better??
