Fan header dead?

[Bausparkadse]

Hi,

i just noticed that one of two fans on my cpu cooler doesnt seem to work anymore. I tried switching between cpu primary and cpu opt fan headers, and the problem remained on the cpu primary header. With the cpu opt header both fans work.

I also tried resetting the bios, did not help with this problem.

 

Might this be a setting issue or is the header dead?

Im kinda lost on this one...

 

Thanks in advance for your input!

Try disabling fan control. So that it runs at full power. It could be the motherboard is trying to run the fan at a to low speed. Otherwise it does indeed sound like it has a problem.

Tried that now, sadly it still does not run... So i guess some 4pin extension cables and using other headers is the solution

Yes, that sounds like the immediate fix. This could be a bios problem that can be solved with an update. But since it started without changing bios version, I doubt it. Doing a RMA for the motherboard would be the proper solution. But, depending on where you live, that can be a real pita.
