Resetting the SMC solved my MacBook Air Fan Noise With Lion problem

Posted by jpluimers on 2012/01/09

This might have been caused by my MacBook Air haning itself one time during resume: I manually turned it off keeping the on/off switch pressed for 5+ seconds, then rebooted.

Anyway: over time I observed that the fan was running fast without much CPU/GPU/memory/disk activity.

Resetting the SMC like the answer below, followed by resetting the PRAM and NVRAM solved my issue.

I had exactly these issues with my new Macbook Air 13.¬† Having read this forum I downloaded istat pro and discovered that my fan was always running at over 4000 rpm and the top left part of my case was quite warm.¬† I then followed the instructions here…resetting the SMC and after this the problem was fixed!
