Very hot CPU

[Pavica]

Ok.. I have an MSI K8T-Neo motherboard, Athlon 64 3000+ CPU, and (2x) SATA hard drives in the following air-flow configuration. Intake: (2x) 80mm in font and (1x) 6" x 6" Fan that I mounted into three empty 5.25" bays. Outflow: (1x) 80mm fan in the acrylic window, (1x) 120mm fan on the top, and (2x) 80mm fans on the back. Also, I have artic silver 5 on my CPU. Yet for some reason when Idle my CPU temp is at 55 C. (131 F.) is this normal? Im not sure of the normal heat output of an Athlon 64. And if not, any siggestions?

I have a very similar setup with the MSI K8N-NEO Platinum and a 2.4 Ghz A643400+. I believe select MSI A64 boards report temps. about 10-13 Deg. C. higher than the real temp. My case is very well-cooled as well. The HS and the case temp. isn't too high, so i'm not worried. I think you can fix this issue by downloading a new bios from MSI. I'm not going to do this, because I think it's too much trouble for a relatively small issue. All progs. run beautifully on my system, however if you are experiencing problems you could try installing the latest bios. I actually don't know how to and have never done this, so I wouldn't be the person to ask.

Well thats a good idea, seeing how I bought all my computer stuff when it first came out if you cant tell by the motherboard and CPU used. So the BIOS is old. But also like you, everything runs beautifuly on my computer. I would still update my BIOS though because I like to keep things updated, but I can't because I dont have a damn floppy drive. Those things are useless exept for stuff like this, and the windows textmode drivers.

FWIW my P4 3.0GHz Prescott idles at 55 deg.C. 65.5 deg.C full load. No stability problems despite lack of fancy cooling (just side, front and rear fans).

Id be tempted to reseat the heatsink. It may look right and provide enough contact to be stable but the cpu surface and heatsink surface may not have mated properly.

The BIOS issue is probably a valid one and probably your problem. I know ABIT has a Windows-based flash program for its Nforce2 BIOSes at least, perhaps MSI offers such a program since you mentioned your pc lacked an FDD.

depends on heatsink, depends on fan speeds, depends on case and hole sh*tty its grills are. depends on if ur m/b supports the auto fan speed control/cpu speed control feature. silentpcreview.com has more. and of course, the accuracy of ur mb sensors.

Well you pretty much covered it all.

I would upgrade your bios first. I know at least for my board (MSI Neo-FIS2R) the latest bios revision corrected (for the most part) the motherboards incorrect temp readings. But from the temps your getting, id say you have problems elsewhere as well, and I can't believe that the sensors could be off by that large a margin. To give you a comparison, my 3400+ idles at around 37-39 C and the highest its gotten was under burn-in at around 54 C under heavy load.
