Control Macbook Fan
Fan control automated by default. But, sometimes the temperature percept in my hand just doesn't feel right, it's too hot. So, to increase the blow increment the fan minimum speed using the following command.
# value=4000 # echo $value | sudo tee /sys/devices/platform/applesmc.768/fan1_min
$value can be set between 0 - 6199 in my case.
Fan not blowing, is it broken?
Well, maybe the fan quiet enough to be hear. But, on the speed around 6000, it will be noisy enough. If it is not, maybe some parameter is incorect.
Fan Manual Mode Active
Fan has two mode so far I know: auto and manual. Set to manual so that the driver
fan1_min parameter we've set.
# echo 0 | sudo tee /sys/devices/platform/applesmc.768/fan1_manual
