Cleaning out dusks from CPU fan

Dusks has settled on the CPU fan blades, I'm thinking of cleaning it :-

(a) suck it out using vaccum cleaner or
(b) blow it away using hair dryer

It's better to be safe than sorry and decided to check it out with experts here.

If you take it off the CPU, pretty much any method short of sandblasting is good, since the fans are not particularly static sensitive or anything. I usually use a cheap paintbrush, since quite often the dust has caked hard on the blades and unless you have a very high pressure air source it won't move. For heatsinks, which are usually pretty dusty when the fan is, I usually seperate the fan off them and run them under the tap (faucet) in the sink, this is the cleanest way to do it. For general dusting inside PCs a vacuum cleaner with an antistatic stiff bristle brush nozzle is good. However it's hard to get a good one of these for a reasonable price, you could end up paying $30 online, and get the exact same thing you could have bought in a local discount department store for $2.99. A good compromise is to set up the household vac suction tube near where you are dusting, use a cheap paintbrush with a metal ferrule, hold the brush by the metal, hold the PC case with the other hand to ground yourself, (or use a proper ground and wrist strap if you have one)  and flick the dust toward the nozzle.

Do not use either one of your choices. The elelctrical current generated by these appliance could have an adverse affect on your maachine. Use a can of compressed air to spray the dust out of the fan.
