Hi all,

The fans in my iMac have always been very quiet, as I do not usually use it for intensive work.

However, today, I just noticed that it was noisier than usual, even right from cold boot.

A check with my iStat Pro showed that the fans were all running at relatively high speed of 4500rpm and above, even as when the temperatures were averaging 37 degrees celcius.

May I know what is wrong here?

Luckily there's still warranty, as it is barely 6 months old.
