Determining CPU temperature

ny_driver · #1 10-08-2010

From what I gather you go by the temperature of the cooling unit on the cpu because the software is screwy when it gets sub-zero. If that is the case, then I can say my CPU is running close to -37 Celsius.....correct?

What I have said seems pretty obvious and I almost feel dumb asking, but hey I'm a greenbean here with the subzero computer world.

Thanks for reading.

What do you mean....you've already LN2'd the 965BE it appears.......

....nice OC brother.

Correct. Generally the probe is about as close to the base as you can get it. Actually I think ALL pots made nowadays come with the hole pre-drilled. Basically there will always be a delta between pot and CPU temps, but it is all relative in my book. Plus short of successfully drilling a hole in the IHS and placing a probe there is no accurate way to know real CPU temps. Just go off of the probe on the pot.

I will add that by saying the temperatures are relative, the delta and "real" CPU temps don't matter. As long as your CPU consistently CB's at -140c pot probe temp, do you really care what the "real" CPU temp is? I don't because as long as the mount is a good one it doesn't matter. It helps you absolutely zero to know that the CPU temp is -120c on the IHS if it also reads -140c every time on the pot probe.

That's a good way of looking at it. I totally agree.

My temp probe is touching the base of the block and the egde of the IHS, unless it moved, and reads -35 C right now which is colder than the coolant by ~8 C. My insulation seems to be working like a tiny freezer.

I don't have a hole drilled in my waterblock....or my F1EE for that matter. But anyways I'm pretty sure I got the probe where I wanted it.

Thanks Chuchnit

Chuchnit nailed it.

I had too much thermal grease and so the block temp was reading higher than it should have been(wasn't making good contact). I remounted it today with a nice small drop of grease, and the block temp is the same as the coolant now. I think more heat is being drawn out of the chip. I'll have to try 5GHz again later.
