Intel thermal sensor bottom limit?

post #1 of 6
Thread Starter 
I think my E2200's sensor bottoms out at 1c. I set my Small Arms ammunition case in my open window (its -11c outside) and let it run, after sitting at 1c for ten minutes I figured it won't go lower.

just because it is cold does not mean that the proc will drop to ambient temps.
staying 12c above ambients sounds normal to me.

But exactly 12c above? After starting, it dropped to 1c in a few seconds, but never lower.

Nice wallpaper. Where can I get that?

You're quite right, I've read that a lot of sensors used in chips don't measure beyond around 0oC.

Simplest reasoning is, there is no need to, primarily temperature sensors are there to stop overheating so there's no need for them to stay accurate at low temps.

of course every CPU is different, I don't know if you're cpu would have that limitation. but that'd what I'd expect is happening.
