Before you get started go to your local Wal-mart in the electronics department, and pick up a can of compressed air. It is a good Idea every once in a while to open up the case and blow out all the dust that builds up in there. Over time a lot of dust can cause the temps in side your case to rise and over time may be one of the reasons your fan fried.

I clean out all my PC ever 3 months or so just to keep them from getting over heated. I also have my vaccum cleaner going at the same time. What I do is when I start blowing out the dust the vaccum is used to suck the dust in to the vaccum, rather than blowing all over the place. I have also use the vaccum very carefully and sucked out the dust when I did'n have any air. Hope this also helps.
