New NUC7i7BNH - CPU Core Temp Running at 70c While Idle

Jump to solution

Hello,

I recently purchased a NUC7i7BNH and installed a 250GB Samsung 960 EVO M.2 SSD and 8GB of Crucial RAM. I flashed the BIOS to BNKBL357.86A.0060.2017.1214.2013 and installed Windows 10 Pro with no problems. However, the fan was running louder than I'd like. I went into the BIOS to adjust the Fan Control Mode to "Quiet," but that didn't seem to have any effect. I even changed it to "Fanless" and still no improvement. The fan constantly runs at 3,400 RPM according to the BIOS, but I noticed that the CPU Core Temp is running at 70 degrees. I wouldn't expect the temp to be that high in the BIOS. Am I mistaken or is there something wrong with this unit?

Thanks in advance for any input.

When you are in BIOS Setup, all power management features and interrupts are disabled. This means that you could see higher-than-expected temperatures in this state and you cannot conclude whether anything is wrong.

I find that the supplied fan speed control configurations are nigh on to useless. I suggest that you use a customer configuration. Here is what I use:

Hope this helps,

Thanks, Scott, for your informative response. I set the fan settings to what you described, and the fan is quieter when system is idling in Windows 10. Just wish I could say the same when there's even a slight load on it.

HI,

 

Have you blown some air through the fan and cooling fins ?

After about six months of running, my NUC I7 needed it it. Solved the issue.

Techno,
