Yeah I try to clean the dust from the heatsink/heatpipe every 3 months
or so. It tends to make the machine run way quieter, and makes the fan
happier, and the system cooler. One time I did my wife's laptop and it
dropped the temperature of the CPU by 15C and the fan stopped running
at full blast.
I find that a Q-tip works well after removing the cpu fan. Making the
tip damp makes it collect the dust better (but not soaking wet).
