SMCFanControl lets me set a higher minimum fan speed on my MacBook Pro (I like to keep it at about 3600rpm instead of 2000rpm minimum). Is there a way to do this with the MacBook Air? SMCFanControl doesn't seem to detect the MacBook Air properly. Essentially I want it to run at around 3600rpm and increase to 6200rpm as needed. It should never be running lower than 3600rpm.
