Ping,Ping,Ping

Hi there a mate of mine at work said to me that when he starts his PC up, he hears a metal upon metal sound that gradually speeds up then then goes away after 2 minutes or so.
He says it sounds like pinging noise I've said to him just take the side panel of and listen to where it's coming from,but he won't.

Any ideas on what it could be?

By the way i'll probably show him this thread later

Is that on the CPU, if so is there a fix, or just replacing it be easier

Well he bought it from the (purple shirted place) ,so he'll probably take it there and get it fixed.
TBH i think that's probably the best option for him cos he bought the thing there.
