I just received my month old iMac today from repair for iSight related issues. Although iSight is back up and running, the fans now have increased in speed and are making a very loud sound almost as though they're in overdrive. This has been happening from the very first moment I plugged in my mac upon receiving it from repair. I tried the SMC reset but it's not responding. According to iStat my fans are operating at:

Optical Drive: 4350rpm, Hard Drive: 1099rpm, CPU Fan: 3856rpm.

Is this normal and if so what else can I do to silence my fans back to the way they were? Please help. I don't want to have to send my iMac back in for repair again.

i had a similar problem when the repair person forgot to plug in the temperature sensor for the fan. it ran high all the time. i did take mine back, luckily i could drive the 45 minutes to get it fixed.

No, it's not normal. As the previous poster stated - they more than likely forgot to plug in the temperature sensor. You need to take it on back unless you want your fans to be damaged. Be sure to speak to the manager of the store and let he or she know that the previous repair was not done properly.

Regards.

Thanks for the advice. I guess I have no choice at this point other than to take it back. I appreciate the advice though!
