Asus ROG Strix 270e Motherboard

[dig69]

Hi, I have just insatalled the above board and all is well except the Chassis fan header 1. I have checked in the bios and it shows fan running, but the fan only
runs for a brief moment when booting up and then stops when windows loads.
Fan expert does not recognise the fan header and neither does the Q setup in bios. I have been forced to use the cpu-op & io-pump headers for my extra case fans. PS Sorry should be z270e.
Any advise would be greatly appreciated.

Thanks

Have you tried connecting another fan to the header to test it?

Hi Chino thanks for the reply.
Yes I have tried another fan. I have 5 Noctua fans in my case, 2 for the noctua cpu cooler and 2 140mm & 1 129mm case fan.
When the system boots the fan in chassis 1 runs until window 10 is loaded and then it stops. I have been into the bios Q fan and it shows the fan running
at 23orpm but it is not turning at all. When I go further into the Q fan monitor it shows less parameters than the chassis 2 fan, which works well.
Mate I hope I explained this well enough.

Again thanks for any help.
Regards

Try setting the fan header to Turbo mode. Save and restart. See if the fan stops spinning.

Really odd , bios shows fan not spinning, but it is, then after I set to turbo bios shows 3100rpm far greater than the fan can spin, although the fan still
spins at normal speed. Then I load windows and the fan stops and the Fan expert does not see it. I'm thinking of re-installing the AI Suite or I"m beginning to think it
is a faulty motherboard.

Well uninstalled AI Suite 3 and the fan is now recognised by the Q Fan in bios and spinning normally after boot up. It would appear that the suite was the problem.
The downside is that I really like AI Suite 3 and it's other features and the fact that I could check temps without booting to bios.
I just can't win.

I had suspected that to be the problem.

Out of curiosity, were you using the latest version of AI Suite III for your motherboard?

Yes mate I think so , it updated when I first set it up..EZ update ver 2.03.01 Duel Int Processors 5 1.03.77 System Info 1.01.04. if they are the latest versions.

Also Chino, I also notice that all is ok with fan speed etc on Fan 1 until I do a fan tune through Fan Expert 4 and then Chassis Fan Header 1 is not recognised again.

The motherboard is thankfully working ok, but it's a software problem through A1 Suite 3 it seems.

Very strange.
