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.
Is this a good question?
