Asus Rog Strix z690 E mobo. Noctua CPU fan. everything brand new and has been working fine for a month. This morning, turn PC on and I get the dreaded "CPU Fan Error" message with the invite to fix things in BIOS.
Things I've done...
It was fine yesterday...just powered on today and fan said "not today".
Things I've done...
- Plugged fan into CPU_OPT instead - same result, fan spins up on power up but then stops completely once POST is complete to never come on again until start up again (it twitches on power down).
- Plugged fan into Chassis 3 port - runs fine, no probs...but that's not the CPU fan port driven by CPU temps.
- Plugged another noctua fan into CPU fan port to help troubleshoot
- Upgraded BIOS to latest version (2103) - that reinstated all the CPU fan error message which I set to ignore again and gave me a new error where the CPU fan error gets displayed. This one says "Your Cooler has been somewhat characterized. Press F1 to enter BIOS" (I say old chap!)
- Tried manual controls for the CPU fan via BIOS and via windows apps.
- Sent a support request to ASUS. They're taking their sweet time getting back to me. An A$900 motherboard shouldn't have these issues.
