For the last week or so, the optical drive fan in my iMac would suddenly rev up to 5000 rpm , ( thus making a fairly loud noise ) , after "waking up" from an "energy safer" induced computer/display sleep of 15 minutes. If I don't put the computer/display to sleep, the optical fan would just stay at 800 rpm and no undue noise.

To get rid of the optical drive fan noise, I have to shut down the computer for 15 minutes and restart it.

What is the reason and how can I fix it?

Thanks.
