Sorry the top post but want to insure you

1st - vacuum it out insuring the heat sinks are cleared


You should *never* use a vacuum cleaner inside a computer. If you do
so, you run the risk of a static electricity discharge frying the
motherboard.

I agree in theory, but in practice I'm not nearly so strict. I've used
a vacuum cleaner well over a thousand times over the years and never

I think I have seen vacs specially designed for use with computers.
Expensive (overly so, I think), but presumably static-dissipative. I'm
talking about mains (US: line) powered ones, not the USB-powered mini
ones that are really just for cleaning the keyboard.

had a problem. Like registry cleaners, though, there is always a risk.
I minimize or eliminate that risk by leaving the PC plugged into the
AC outlet and periodically touching the wand to the PC's case during
the cleaning operation. That's how they taught it in my Air Force tech
school some 40 years ago and it works well.

Much more effective, however, is using compressed air instead of a
vacuum. It's a lot messier, blowing dust bunnies everywhere and best
done outdoors, but it's much more effective.

ISTR the vac. I saw could be used in suck or blow mode.
