Where is the CPU temperature sensor?

fragbait · 28-11-2003, 07:12 AM

How does a motherboard read the CPU's temperature? Is there a little temperature sensor placed near or below the CPU? Or does the CPU have it's own built-in temperature sensor and the motherboard just reads it from the CPU?

It's usually located on the board in the middle of the cpu socket under neath the cpu, if the board has a system temp probe also, that will be at the bottom of the board in one of the corners usually at the back of the case,

Depends on the CPU. Since the Palimino-based Athlons (the beginning of the AthlonXP ratings) and the Pentium 4 and any Celeron 1.7GHz and up has it's own temp probe in the chip.

Thanks guys. I was just curious on how acurate the temperature readings are. If it's built into the CPU, then it would be more acurate as opposed to having a probe outside which could vary.
