[Collins] Boat Anchor Fans

[Jim Brannigan]

I don't get all this "fancy fan" stuff.
A 110VAC muffin fan on top of the cabinet with stick-on rubber feet and an
in-line lamp cord switch works very well.
Periodic cleaning, particularly power Amps., is a must.
Wipe off the tubes and clean the fan blades with "Simple Green" and a paint
brush.
There is a vacuum cleaner reduction kit sold for use on computers.
An attachment reduces the standard vacuum cleaner hose to a 1/2 inch tube
about two feet long.   Small brushes and a crevice tool are included.
It does a great job.
Speaking of dust.  If you want your computer to last, open the case and
vacuum clean the power supply fan openings and CPU fins.
