My main desktop was making some whirlwind noises inside the panels for several months now... like the fan was blowing hard and any processing caused the "engine" to sound like it was going to take off.

I knew it had to be cleaned sometime but I didn't realize how much dust and dirt this thing had accumulated! I applied some light air from an air compressor and I was totally amazed at how much crap was in there. Best thing, it stopped making that noise like it was going to get ready to blow up!

I used to buy junk computers for parts of Gov't auction sales.
Filthiest machinery on earth. Maybe static attracts the dust?

Little Campbell-Hausfield air compressor, open the computer out doors and give it a snort.
ALWAYS stand up wind. Who knows what the dust is.

Plus, the dust means less cooling, it runs hotter, and that means more fatigue on the boards.

Open it up. Grab the frame of the computer with one hand and a vacuum cleaner hose with the other and vacuum it out. Not only might there be astatic charge that collects dust, but over time that fan pulls a LOT of air though the unit. Cleaning it ought to be a once-per-year thing.

Yessir. When the fan mesh screen over the output is gray and furry, time for a vacuum.
I like to use the soft hairy curtain brush or a soft 2" paint brush.

If you have pets they clog up pretty quick! Same with your bathroom exhaust fan.

Ya had me for a moment there...

....I thought you were gonna say and "tap it briskly on a hard surface."

Did you try turning it on & off?

If you want to hear some horror stories talk to a PC tech. I have opened up desktops and found mouse nests, dead mice, I have not found snakes but have friends who have found them, all kinds of insects. When I used desktops I would take the CPU outside, take off the covers and use a compressor to give it a good blow out. As Brian said, stand upwind.
