Hey Guys, My good old 08 Macpro is getting quite dusty underneath my desk so I was thinking about cleaning it out really well. Now I have read on these forums a great many tips of getting the dust out of small places. I am going to try out the paper cup trick were you place a straw in a hole through the bottom of a paper cup. You then place that cup over the tube of the vacuum cleaner so you can get the dust out of really small places. I was wondering how one services the fans? Don't they need some WD-40 or something? I am not hearing them at the moment but I'd like to take good care of my computer BEFORE something fails and not after. Anyone got any tips? Thanks in advance!
