PowerBook fans (cooling devices, not aficionados)

[Brian J.Sletten]

I have a Rev. B 667MHz Ti that has had a dying fan for a while. It not 
only makes the characteristically embarrassing noise when it activates 
properly, it has alternatively been sounding like a dying duck, a hip 
hop bass line or a NASCAR ride with engine problems.

Does anyone have any advice on replacing the fan? How difficult is it? 
Any recommendations of vendors in the Washington, D.C. area? I'd rather 
not have to send the machine anywhere but it is getting to the point 
where I have to do something about it. I'm willing to do it myself if 
it isn't too exotic of a procedure.

Thanks in advance,

Brian
