when i use my imac then fan never runs atuomaticaly even though the top is burning but it works with smcfan control how do i make it run automaticaly?
Do an SMC reset. Unplug the power cord and let it sit for a few minutes. How can you tell that the fans are running at all? These machines idle very quiet. Install the iStat Pro widget to monitor fan speeds and temps.
heres info. try using a different fan
