I've always had to run it 3-5 times in a row to get it to set the PWM Fans correctly, but I can't now, get it to set anything under 100% as the minimum Fan %, even then the Fan detection issue is not gone, so I have had to now set the CPU Fan to Ignore, and each Fan to Silent or Standard Mode, so the computer will boot into Windows.
I have not tried resetting or reflashing the Bios so far as I didn't see much point but will if others think it is the only possible cure, I will, as having to keep an eye on Fan Speeds etc is a PITA via Software.
Thx for any ideas on this one....
So after trying a CLR CMOS and even a Bios Reflash and building my OC Settings again nothing changed, and it was only while running Opt. Defaults, that it would set the CPU fan to anything but 100% , in Opt. Defaults it set the Fan to 20% on low and Mid but if I tried to adjust either, at all, they both flipped back to 100% again.
I had noticed through all this that the CPU OPT Header RPMs were set as expected (1000-3000 rpm) but wasn't sure why? since, it's supposed to be a copy of the CPU Fan Header yet the CPU Fan was showing RPMs from zero to 19000 +/- 200 RPM in HWFinfo ( yes 19000
). So for no real reason and out of Ideas, I decided to tie 3 of the 4 AIO RAD Fans to the CPU OPT Header instead and I then replaced the CPU Fan itself with a new one, since I had one on the Shelf still from another build , and it's all working again...which seems strange as the Original Fan is still working Fine it seems but somehow must have lost just the RPM Sensor part perhaps? , at least I can't think of another reason.
