[Feature Request] Check if Fan really follows the target curve
n300home opened this issue · comments
Hi There,
Is there a possibility to implement a plausi check, if a fan really follows a designated target curve?
I'm asking, because I have a buggy PCH Fan Controller on my Mainboard. Sometimes the PCH fan speeds up to maximum RPM and stays there until:
- I shutdown or standby my computer
- or Disable/Enable this PCH Fan in in Fan-Controll
My idea would be to check against calibration curve, if its really plausible that the fan runs over 5000rpm although 0% PWM-Signal is given in target curve. If this plausi check fails -> send and overrule once more the actual target value to fan controller.
Relevant hardware specs and setup
My relevant "problem fan" is the PCH-Fan from Gigabyte X570 Aorus Master (rev.1). Imho there is a flapping Temp-Sensor, which sometimes sends inaccurate temperature data, what ends up in a "Panic Mode" in mainboards UEFI Fan Curve.
That's what "Force Apply" is for.
Oh I see the % readout is still 0 and only the RPM sensor goes crazy. Force apply is based on the control sensor.
I could add a new check indeed by checking the expected % out of the current RPM+calibration. If the difference is large, greater than let say 25%, we could assume there is an issue and fireup force-apply.
Oh that sounds really great :)
many thanks
