Hi guys,

i like to ask why the pwm headers of the board will drive the fan to above the stated max RPM of the fan?

When I set the target temperature of the processor to 55 degrees and target speed level of 2, when the CPU is 60 degrees i see the fan speed keep going up and above the max rpm of 1800 till hitting 2000rpm and it doesn't seems like its gonna stop..

Your fan rated speed maybe +/-200rpm.

Your fan rated speed maybe +/-200rpm.

I think i fried one Jetflo before.. it keeps going up till some weird noise comes out from the motor area..

After it happens the Jetflo just kept having the noise there. Now I m unsure if i shld use normal pwm fans and set the target temperature lower or not.
