hi..! what's the difference between core temperatures and the temps shown by the mainboard( bios)?
i use intel core 2 duo E6300 OC @ 2,3 GHz and get 55C each core( using TAT) and the bios shows 64C for CPU (on idle for 3 hours).. which readings should I rely on?

note:
mobo: ASUS P5B (BIOS version 0804)
Power supply: cheap 500W power supply from Basic & Power ($30)
Heatsink: stock
thanks!
 
The 64C is the totaled cpu temp which is on the high side there. Most likely you are running a stock hsf with a load like gaming or multimedia to be seeing the temps there. The core temps are always lower then the bios reading. Refer to the bios hardware monitor which shows the actual cpu temp.

You can also download a freeware like SpeedFan, Everest Home edition, or SiSoftware's Sandra Lite 2005 or 2006 to monitor cpu and other system temps while in Windows. Note these freewares can be a little shaky at times with dual core model cpus however. SpeedFan is found at http://www.almico.com/sfdownload.php
 
sorry, got cut there...
so, 2 days ago, I wanted to replace the CPU to the store, then the repair guy tried it out with his computer, and it turns out, that the CPU's temp is only 40C in the BIOS. and when I tried it to my computer again, it shows more than 50C in BIOS after turning on the computer..
so I guess, there should be something wrong in my BIOS, although I already updated it.
I already tried the softwares you mentioned, and they all show the same as BIOS. any suggestions?
 
The problem there sounds more like the cooling is lacking. At the store the "whoever" installed the cpu in another build for a few minutes to see if the cpu was any good. He certainly didn't allow it to run for any lengthy period of time to see what temps would be seen there. Besides replacing the thermal pad on the original heat sink/fan combo you may want to consider a much better 3rd party type cpu cooler.

The readings seen in the bios matching what is seen with SpeedFan or one of the others is a good sign that those are reliable and you are not seeing false misreadings with exaggerated temps. If the bios settings(voltages, etc.) are all at factory cooling the cpu is the concern there. The original thermal pad on the hsf was probably worthless.
