I know there is a build-up of dust within my iMac 24" (mid 2007) and I would like to blast it out with shots of compressed air. I'm worried of over revving the fans and generating a back voltage damaging my beloved computer! Help please.
iMac, Mac OS X (10.6.3), iMac 24" (MA878LL/A) 2.4GHz 2GBDDR2
If I hadn't done this regularly (once a year) I think it would be appropriate to vacuum the machine from ALL enrty ports first.I've put compressed air (from my compressor) into all the openings of my several iMacs without consequence. My compressor has a regulator on it and I keep the PSI at about 60. I start with the slot at the top rear of the machine, move to the A/C hole, then the several ports (USB, Headphone, Firewire, etc.) I also blow into the Superdrive slot. Then I Vacuum the memory slot area thoroughly with the memory modules removed. Earlier this spring I actually took the iMac apart and noticed that the fans get a dust buildup inside the impellors themselves. I don't think you could dislodge the buildup without air directed at them in close proximity
I use a 100 PSI compressor.
Never thought about back voltage though... I've had the fans revved up pretty good all my computers.
I have the following:
Metro Vacuum ED500 DataVac 500-Watt 0.75-HP Electric Duster
I has predominantly good reviews and there's also youtube videos of it.
How do I clean the dust out of my iMac, Compressed Air?
