I have a relatively new build, details are below.
My CPU fans randomly stop working all together, and will not restart without rebooting. I could use some help figuring this out. This is on a Gigabyte Z97-UD5H board.
In the Bios I have:
CPU fan speed control set to "Normal"
CPU/CPU OPT/System Fail Warning "Enabled"
CPU OPT Fan Speed Control set to "Normal"
I am using Gigabytes SIV (fan controller) and have "smart fan" enabled.
After the system sits idle for some time. I have noticed both CPU fans are idle (not always) and they will not restart unless I reboot.
When this happens I have opened SIV changed fan speed to other settings (max, quiet, etc) but the fans will not restart. I tried to re-calibrate the fans within SIV but they do nothing. Re-calibrating does seem to give a possible clue as windows event logs show this error (only after trying to re-calibrate). I do not see this error in the event logs unless I try to calibrate the fans when they are not working. No other related Windows events are there

Only rebooting gets them started again and they work fine for a day to two, then they symptoms randomly repeat
I have checked the connections, they seem fine, nothing touching the fans.
I did upgrade (ok they look better) the Noctua fans to these Noctua fans (NF-A14 iPPC-3000 PWM), but can rule this out as I had the same issues with the ugly Noctua fans.
