Every so often, I take a can of compressed air, and blow out the dust from
the fan exhaust on the bottom of my 3/60, and along the back and sides of
the beast (under that plastic cover is a metal case with louvered air
intakes.

My 3/60 runs a lot cooler when I do this. Big Heat is bad for computers;
this is why machine rooms are generally very carefully temperature
controlled. And humidity.

Me, I have an extra problem: no A/C, and my housemate breeds maine coon
cats (long hairs).
