Overactive fan after fsck-yf

Hi, I hope someone can help please!

After running the fsck-yf command, we've had a few instances in our office of the iMac's fan going mad. (very noisy and lots of air shooting out of the back) It doesn't seem to want to stop, can anyone tell me how to make it stop please?

Thanks in advance

Hi:

Can you tell us why you ran FSCK and when you did, what did it report back had been repaired if anything? Then we can go from there.

Regards.

Hi

Thanks, it was my colleague who ran the fsck after she had upgraded from Panther to Tiger. When she ran Software Update for the first time after the upgrade she had a few problems with it, so did fsck. It didn't repair anything as far as I'm aware. I've had the same problem myself after running it - the fan just seems to go crazy. It kept like that for perhaps 2 weeks before suddenly just stopping.

OK, I understand. It may have just been file indexing after the update which caused the hard drive and CPU to work harder. That in turn causes temps to rise, hence, the fans start spinning faster to cool everything off. Although, it would seem to me the whole index process should have completed in several days not weeks.

Regards.

Thanks - I'm sure it's not doing any damage, it's just very off-putting with all the noise it makes.

Is it worth me advising her to reset the SMU perhaps?

i've seen this many times on Imac machines. the fix is very easy. Restart the machine in single user mode. once it is started up type exit at the prompt and hit enter (instead of typing reboot). the machine will restart and the fans will be working correctly.

Thanks for that. Could you clarify for me please what you mean by starting in single user mode?

hold down cmd+s at start up.
