Subject: pwmconfig: Further raise the fan threshold

Modern 4-pin fans can have a minimum speed (PWM=0) which is still
|
|
relatively high. I've seen 4500 RPM fans lower their speed to only
|
|
3500 RPM, which is 77% of the maximum speed, above our current
|
|
detection threshold (3/4 or 75%). Increase the threshold to 5/6
|
|
(roughly 83%) to make sure such fans are handled properly.
