    It's been a very long time since I opened my desktops and gave them a good cleaning. My question is this: When cleaning the CPU/heatsink with my can of compressed air, it is almost impossible not to get a spay or two of the liquid coming from the can on these parts. How harmful is this to those fan and heatsink parts - does it help to shake the can real, real good or will that make it worse or doesn't it matter ?

    Any suggestions on how to prevent this?

    The liquid that comes out of compressed air cans is condensation and it evaporates quickly. When finished cleaning your computer just wait a few minutes to make sure everything is dried up (optional).

    I stopped buying and using cans of compressed air a long time ago.
    Besides the cost and not being very long-lasting, there's the condensation issue if they're not held at the proper angle.

    A cheap portable hair dryer on its coolest temperature setting and highest blower setting is what I use.
    This has worked well for me for several years.

    Note: If the processor's heat sink is badly clogged with dust, you may need to remove its cooling fan unit first to properly blow the dust out of the heat sink.
    This applies to whatever you use(compressed air, hair dryer, etc.).

    An air compressor using a blow gun with a VERY small nozzle works well for me. In addition, I take the system out to the garage and having a very long air hose from the compressor, I can have the system outside [not blow dust inside the house or garage]

    I get a guy to clean my computer mainly because I'm afraid of using compressed air. I'm afraid of anything that says it can kill you on the label. :D But I do some cleaning with a brush in between because I live in a dusty area and have a dog that sheds constantly so it has to be cleaned often. My guy told me (and I've also read) that you should never shake the can at all as that causes it to create condensation inside which comes out when you spray which is something that you want to avoid. You should also always hold the can in the upright position, don't turn it upside down or sideways and use short bursts rather than long ones to help prevent condensation.

    I have always used a 3 HP portable vaccuum to clean my computers. Does the job real well. I only used compressed air when necessary.

    I've been using a shop compressor that has an air dryer.

    Good idea to stick a slender piece of wood in cooling fan blades so as to not over speed fans and damage them.

    A lot of dust accumulates in the PSU, also.

    Often a can of compressed air, when shaken, will make a good replacement for freeze spray, another tool we used to use to detect problem components on motherboards (back when it was still economically feasible to actually repair them instead of replace them). If a component failed when warm, it would often work again when cooled.

    Thanks everyone - some real good suggestions. I finally used compressed air since I already had several cans. I found that if I just did 3 or 4 quick burst the can wouldn't spit out an liquid. Worked out without any wetness at all. All back together and working great. Going to do the hair drying next time I clean then - sounds a lot easier.
