What is more accurate when it comes to monitoring your temps.

Bios or software like core-temp or speedfan?

When I enter my bios H/W monitor menu...the CPU temp is at around 45/46c...but in Windows, when I run core-temp/speedfan it shows the idle temps at 40/42.

Is it because the CPU is under load when in BIOS setup?

  1. CPU isn't under load while in the BIOS, but if you have cool n quiet/intel speed step enabled, I don't think those work in the BIOS. So although both are idle, within windows you have a lower clock speed/ voltage meaning cooler processor.

    I could be completely wrong on this, I've got no evidence to back it up, just a theory.
  2. i cant answer your questionjust thought i would throw in what ive found, i was rrunning 3 diff progs that give me temps in windows and each one quoted a diff tep 10 degrees diferance between the 3. Im thinking physical methods would maybe be better for watching temps. Ie a front pannel moniter of some kind.

    Core temp reads the temp on each individual core, and I believe that the BIOS reads the temp at the socket. No the cpu is not under load when in the BIOS.
