I realize that this question has been asked a million times, but bear with me.
Usually but not always (approx. 7 out of every 8 boots) I get a "CPU fan speed error detected" on boot. My motherboard is an Asus Z170-A and my cooler is a Thermalright TRUE Spirit 140 BW Rev A.
I've triple-checked that the CPU fan is plugged into the CPU_FAN connector correctly, and definitely not plugged into the CPU_OPT connector. The UEFI reports that the fan is running at ~320rpm. The minimum fan speed in the UEFI (below which an error should be reported) is 200rpm. And the only option lower than 200rpm is 0, which I would prefer not to set.
The CPU temp is usually around 27C.
Here's the weird part: Most of the time when I boot up, the CPU fan slightly twitches, then doesn't move for 4 seconds, and then starts spinning. From what I understand this is normal CPU fan behavior. But every once in a while the CPU fan starts spinning immediately, without any delay, and these times are exactly the times when I don't get the "CPU fan speed error detected" message.
The inconsistent fan behavior, coupled with the fan speed error messages, is leaving me baffled. And I haven't been able to find any similar problem descriptions elsewhere online.
Any ideas? Thanks!
