Ive got two computers on which the fan runs every so often. This is what prompted me to open the case and look inside. Lots of dust bunnies in both the desktop and laptop

On the laptop but Im assuming an accumulation of dust is making the cooling of the fan innefficient and thats why it turns on so often.

What is the best way to get all the dustbunnies out?Look here and here..

Good luckI forgot we have explanatory THREADS but - my approach is .........

I find careful USE of compressed air does the trick - use a compressor if you have one and set output pressure to something quite MODEST and fit a nozzle gun - 15 to 20 psi MAY well be enough... otherwise get a can of compressed air or nitrogen gas.

If care is used then a fine camel hair brush (like for photo lens cleaning) can also help before using air - just to losen dust accumulations.... this can certainly help on fan blades ... make sure tho best you can that what is blown out goes away and not into other areas ... best done outside really.

CPU HEAT sink fins can also get well filled with a sorta greasy dust and those too need carefully cleaned to aid cooling air. Do everything with care!i wouldnt use the photolense brush thing for anything then fans though and the heatsink Quote from: computeruler on August 18, 2008, 07:39:30 PM
