Server down. Culprit: dust.
My server went down yesterday!
It was when I came to it to program a bit more on my Arduclema guinea pig that I realized it was off. I quickly opened the case (a 1.5-second affair on this dual-processsor PowerMac G4 MDD) to see if something was horribly wrong, and I saw the problem immediately: dust had clogged the air intake.
This PowerMac has been modified by me in the past to keep it’s fan noise down; every fan was replaced, mainly the two Nidecs on the power supply, and the CPUs heatink got a couple of specially placed fans and duct. Many air paths were blocked to force simple, efficient intake and exhaust. So when dust settled in, it quickly wreacked havok on the inside temperatures.
I gave it a good cleanup, and here it is, up and running. Again. But one of the power supply fans has given up the ghost and needs replacing, as does a cheap blower that was on one of the PCI bays (exhausting the Nvidia GeForce Titanium).
This PowerMac needs some love…
