My sawtooth G4 has a recurring problem that fits your description.  It's the 
fan on the ATI AGP video  board. Easy test is to stick your finger, carefully, 
on the fan. If the sound goes away you got it. If the fan bites your finger off 
it's something else.

I have been taking the tape of the fan about once a year and applying a tiny 
drop of gun oil. It's a thin 40 mm square thing and so far I haven't seen a 
replacement on the el-cheapo electronics stores.
