Hi and thank you for all the good advice.
I had cleaned out the dust bunnies with canned
air about 4-6 months ago....but....wow!  This
poor computer was gagging for air!  I'm surprised
it was even running, it had so much dust.
I did move it to this new location in the
office after the last cleaning, so I think that
is a pretty obvious clue that I need to move
it to a better spot.

Anyway, back to the problem.  It is the power
supply fan that is making the noise.  I'm not
happy about that since this model uses an
expensive power supply.  I cleaned it thoroughly
with a brush and a vaccum, but the noise continues.

I would prefer to leave the computer on all the
time (or at least until I feel I need a reboot),
but do I have too much of a fire hazard at
this point?  Should I just wait until it dies,
replace, THEN continue leaving it on if I choose?

Thanks again.  I cannot tell you how much I have
come to rely on all the info from this forum.
