Z170 Extreme6 CPU temperature in UEFI

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Hello, I have a similar config (except Extreme7+) UEFI 1.60, and I just noticed the same issue.At first I thought it was the thermal paste that needed to settle in (everything installed 3 days ago), but after testing "A-Tuning" in Windows 10, I noticed the temp was at 31°C, instead of 51°C in the UEFI a few seconds before starting the OS...

I'm not too worried, I guess it's a calculation/conversion problem somewhere that could be fixed in a future UEFI update.

	I would say so long as temps are OK in OS under load you should be fine. I have noticed that temps in BIOS seem to be significantly higher than idle temps in every case I have seen, a lot of different boards from different manufacturers over the years. I suppose it depends on how the CPU voltage and usage is handled in the UEFI. I suspect your temps may be normal though without a Z170 system of my own to test I can't be sure. All I can say for certain is that your in OS temps fall into a more than healthy margin.
