Asus mobo Fan error :: HELP

[furiousTaher]

asus z170p. updated to latest bios...
cm 212 hyperx


Whenever I try to boot my new asus pc it shows 'cpu fan error, connect the cpu fan properly or set the cpu fan speed low limit. press f1 to enter bios'.

In addition to that when I enter bios it shows my cpu fan is not running at all, but when in reality my cpu fan is spinning properly.

I made sure my cpu fan connector is placed properly with motherboard cpu 4 pins...


I already set fan speed low limit to ignore. it still shows the problem.

finally I had to set cpu fan speed monitoring to disabled otherwise I could not boot.


after searching the internet seems like this a common problem with asus mobo? But the thing is even if i use speed fan or open hardware monitor those software does not show my cpu fan. which is astonishing.


also I noticed these problem started after i updated uefibios last week. though i dont want to revert back to pre historic uefibios.

help please. thnx in advance

May I suggest you revert to old version just to check whether your motherboard detects the fan or not, if both the version giving same error then your fan may have issues just my opinion

Are you sure connected the fan to the "CPU FAN1" connector? And does it show the fan speed of the connected fan, as in RPM?

no my bios does not show fan speed now... although fan is spinning. and yes i checked its cpu fan connector not chassis fan

Try pluggin the fan into a different connector to see if it is showing the RPM speed. If it doesn't, it's actually an issue with the fan connector/header?

even if i change the fan to cha1 or cha2 port it doesnt show up in bios or hwinfo although its running

so fan wire got damaged? do i need confirmation by reverting my bios back to basics?
