Performa 550 (with 575 board) - All of the sudden, the fan is intermittent. I noticed that it wasn't spinning, tapped the vicinity, and it spun up. It's quiet and when pushed, spins easily.
The fan is NMB 3110NL-04W-B20. It's also very clean. Do these have a tendency to fail? Or is it more likely that it's not making constant contact with the power pins? Car light bulbs sometimes need dielectric grease. Would a dab here help?
Apple's housing is quite nice; metal frame with rubber dampeners. Although they didn't put provisions for four screws, only two.
Also, while the case is off is there any other handy maintenance?
