[VoiceOps] Single fan loss cause netra meltdown?

I inherited a [small-medium sized] lab with several (a dozen or so) old
SunFire 440s and a couple Sun Netra 440s. Additional air-conditioning was
added at a later date (no precautions, never mind "proper", had been taken
against dust & etc). Of the 440s, several power-supplies were packed tight
with dust and their fans failed (if not the entire power supply), several
system fans also failed in time seemingly simply due to the age.

The Sun Fire 440 servers ran for several weeks at a time before repairs
(various reasons) and survived... But the Netra 440s were added at a later
date and haven't gone through the same torture - so no practical information
there to share.

In any case, it's an interesting finding; do you have a source (might help
me with managers in the future to get repairs done faster :) )?
