Can I clean my computer of dust without taking it apart?

You don't need to "take it apart" but to blow all of the dust out effectively, you do need to remove the side panel.

It's easy to do, and is very important if you want to get those dust bunnies out of there (and you do!).

Dont be scared. Its very simple and I can't imagine anybody attemting to do this messing anything up. Remove the left side panel. There Usually just held on my a couple of screws. Some also have this panel joined to the top, but those are mostly really old ones. Once open just use a can of air duster. Again this is a very easy procedure and confident in you.

Clean Computer Fan

There's air cans you can buy specifically for what your trying to do. There not expensive either maybe 2$ a can. And it's just compressed air so it won't damage nothing

If you can take the fan out that would be great but if not put a vacuum over the fan or any openings in general and sucks any dusk out

uhh well what people normally do.. including me is just take off the side panel... thats it... then begin arrowing it out or w/e I use a air-can they work really really well... I don't find vacuums to work really well for me... but maybe thats just me xD but yea removing the side panel should be enough.

Just take the side panel off and blow compressed air you can take the fans off if you want but if your gentle enough .You can blow compressed air with out taking anything apart.
