Hello,
I'm using fanctrl.pl from this forum to control all fans including CPU on a SuperMicro X11SSL-CF. With my new built, one model seems to be giving me trouble: the NF-P14s redux 1500 PWM. I'm running two of them with the board set to full mode
I've used Noctua's spec sheet to come up with thresholds:
ipmitool sensor thresh "FAN" lower 200 300 400
ipmitool sensor thresh "FAN" upper 1700 1800 1900
These however did not work. Even at 100% the fans would go into non-recoverable and setting a duty cycle did not have an effect.
I tried to massage them a bit but I cannot get them to exhibit consistent behaviour.
These settings work a bit better, but still have the problem of the fans going into 'nc' sometimes:
ipmitool sensor thresh "FAN4" upper 1500 1600 1700.
Also, as soon as I set a duty cycle to e.g. 37%, the fans stop spinning (confirmed by looking into the case), are then listed as not recoverable and only spin up again after a power cycle. I've tried increasing/decreasing the lower thresholds, e.g. to
ipmitool sensor thresh "FAN4" lower 0 100 200
and
ipmitool sensor thresh "FAN4" lower 400 500 600
but neither helps with the fan just stopping completely.
Another mystery is the CPU fan. I have the exact same stock intel fan in the same motherboard, where it's reporting speeds of 2000-2200 max and running fine with these settings:
ipmitool sensor thresh "FANA" upper 2000 2100 2200
On this motherboard, the CPU fan reports 3100/3200 RPM and also goes into nc sometimes. So I'm beginning to think something must be off with this unit? Any ideas what might be going on?
Edit: after a BMC reset, sometimes one of the fans completely disappears from ipmitool sensor list:
FAN4 | na | | na | na | na | na | na | na | na
