I have 24" iMac. When I bought it (4 months ago), fan was very silent, but yesterday when I switched my iMac on, it started very loud. I downloaded istat menu utility to check fan speeds, it shows:

CPU FAN: 3295
HARD DRIVE: 5498
OPTICAL DRIVE: 4401

cpu temperature always shows 25 C

I am only running safari, how can I decrease fan speed ? please help

Rather than focusing on reducing the speeds, if it doesn't slow down to me that says there's a problem because it's not adjusting the speed itself. You're still under warranty, so I'd get in touch with Apple.

Have you tried the usual restart?

How long have you left it? The vacuum cleaner cooldown phase should only last for 3 or 4 minutes.

The easiest way to check your fan speeds and temperature is by using the iStat Pro widget.
