cpu overtemp error

[ddpaulb]

I have: ASUS P8B75-m/CSM, i5-2400.
About 4 months old.
Have had zero problems.
I reformatted my system drive.
For a couple of days since when I do a cold boot or a restart I get a cpu overtemp error on screen. Wants me to F1 and go into bios.
Cpu temp in bios is 31c.
How do I fix the error?

The BIOS likely has a Monitor section that deals with temps, voltages, and fan speeds. It's possible that there is a setting there that refers to max CPU temp. If this value is set unreasonably low than it could be the issue.

Yeah. +1 I think that's part of the "thermal monitoring" feature that's either "enabled" or "disabled?" The BIOS allows for tolerance settings for the fans and maybe the thermal monitoring item for the CPU. Do you have any idea what the temperatures ARE when it reports this? What does the BIOS monitor say??

Bios temp reads 31c.

Check fan connections..

Checked. All OK.

Checked. All OK.

Did you check the "thermal monitoring" feature to see that the tolerances are reasonable?

On CPU fan control in bios?
CPU fan is set to standard profile.
Low fan speed warning set to 500.

I was thinking there might be a "tolerance" range in BIOS that's set too low. If not the case, I only offer this observation. For Intel chips of just a few generations earlier, there were core temperature sensor defects such that the core sensor was "stuck" for the lower temperature range. I had a perfectly good Wolfdale processor which showed 51C on both cores at IDLE!! The monitoring software would show no change until the temperature exceeded 51C.

Other than that -- WTF do I f'ing know about it? I just can't say where your problem comes from there.
