Fan is haywire and I don't know where it is

I'm extremely confused right now. I fired up my Powermac G5 today, and about 20 minutes later I heard some grinding. It went away after about 5 seconds, and I was too busy to look into it at that time. About 10 minutes after that it started grinding again. This time it was grinding in short bursts, at this point I was freaked out and turned the machine off. Powered it back up and it was grinding constantly for a bit, then it would go into the bursts again.

I looked at the fans the best I could, and they don't seem to be having any issue during the grinding, as in they don't seem to slow down or have issue spinning. I really don't know what's wrong with them because they are clean and spinning fine. Just making lots of weird noises. I'm wondering if the noise is coming from something else now.

Where you using the superdrive at all? One of my g5's superdrives sounds like somebody stepping on a goose over and over mixed with a cement truck locking up it's brakes. It still works fine, just sounds hideous.

Ah, I might be a total fool. I had a disc in there that it could've been reading from, but not sure if it would run constantly. I'll check it out next time I can get to the machine.
