Indeed it does more or less the same thing.
So, it helps.
But I would say it doesn't slow down enough the fan speed to be really
silent when the machine is idle.
For instance, with the patch I sent (when idle) :
hw.sensors.smu0.temp0=39.19 degC (CPU T-Diode)
hw.sensors.smu0.fan0=1128 RPM (System Fan)
hw.sensors.smu0.fan1=1128 RPM (CPU fan)
hw.sensors.smu0.fan2=1128 RPM (Hard Drive)
hw.sensors.smu0.volt0=11.88 VDC (CPU Voltage)
hw.sensors.smu0.current0=0.62 A (CPU Current)
hw.sensors.lmtemp0.temp0=33.00 degC
With a speed around 1100 RPM, it is almost silent and it is similar as if
it were running MacOS X.
With the patch you sent, we get (when idle) :
hw.sensors.smu0.temp0=39.02 degC (CPU T-Diode)
hw.sensors.smu0.fan0=1520 RPM (System Fan)
hw.sensors.smu0.fan1=1520 RPM (CPU fan)
hw.sensors.smu0.fan2=1520 RPM (Hard Drive)
hw.sensors.smu0.volt0=11.88 VDC (CPU Voltage)
hw.sensors.smu0.current0=0.62 A (CPU Current)
hw.sensors.lmtemp0.temp0=37.00 degC
... and it's a bit noisy and borring on a desk.
Maybe CPU_TEMP_MIN could be bumped a little bit ?
Thanks !
