Identifying G5 Quad noise

PowerPC Macs - MacRumors Forums - forums.macrumors.com
Hello, first post here. I searched through the FAQ but this link regarding fans is dead (and was for G4 only, it seems). However if I have missed a relevant thread please let me know!

I have a G5 Quad that I purchased from a graphics company selling their old Macs. Under CPU-intensive load, the dull repetitive 'clicking' noise that is audible as it idles, gets louder and louder. I can't quite tell what is generating this noise -- CPU fans? LCS pump? But I am not familiar enough with the internals of this machine to pinpoint it. I have not attempted a 'teardown'.

Overall I would like to make this Quad as quiet as possible.

Thanks.
