So I have a CM 590 case that is pretty good in ventilation but it is a dust magnet too. Now I would like to clean it but I not sure can I use a hairdryer (that can blow cold air) or vacumm cleaner to blow away the dust? I scare they will make my parts got static charge and toast my PC when turned on.

Quote from some old thread

another suggestion is just use feather duster or brush will do the trick. if some corners of the case that the brush unable to reach then try to blow with your own mouth lightly.

you got a red note can kautim =)

it can be remove the dust by using air compressor
it cost about rm30++ 1 tin..

I ever used hair blower those high voltage type.
Not advisable to use. Now my VGA fan is not spinning.

the way to blow the dust using high speed blower, is to HOLD the gpu or cpu fan, not to let it spin freely when you blow with it.. if not the fan will get damage

one method which is to use bicycle pump.
works very well cause i just clean my brother PC, a bit tiring but it works well against all the nooks & holes on the components.

Today, i found compressed air can at Korean Shop taman dagang (Ampang). cost only rm14/can..

I have been using both the compressed air can and vacuum since 1993.
Malaysia have high humidity so NOT much worries on static electricity unless you're in an air-con room and carpeted!

do it in the toilet, the humidity there will prevent any static build up.
