Cleaning the fans without removing them?
My fans keep spinning like crazy, even when just using the browser with a single tab open they end up at 6200rpm and are noisy. I guess this is because of the dust build-ups since everything else works just fine and it started to get noisy quite recently.
Since I am planning to install the new memory modules (2x4GB) tomorrow, would it be of any use if I cleaned the fans from dust since the machine will be open?
I am not comfortable with removing the fans themselves (I'm female and a blonde, fullstop). Would blowing from a can of compressed air do any good or would I just make it worse by getting the dust deeper or perhaps end up damaging the fans?
I was thinking of cleaning everything I can reach with a clean Q-tip if compressed air won't work.
Thanks in advance.
P.S. It's a late 2008 2.4GHz Intel Core 2 Duo; I have already upgraded the RAM to 2x2GB (was 2x1GB) and changed the HDD from 250GB to 500GB. The serial number ends with 11GK, and I'm running 10.7.3 on it.
