WalmMart carries cans of compresed air, and at a great everyday low price!
Using compressed air is safe and easy, as long as you follow the directions. Hold can upright, don't tip it or it will spray liquid. Don't shake the can while in use. Use short, focused burstd (using the straw attachment that comes with it).
Be sure to unplug your comp before yuo mess with it. Be sure to ground yourself often.
I usually take the fan off of my heatsink when i clean my case out. That way I can clean out the fins of the heatsink really good, as well as the fan.
