Hi Yuki: My tech friends use cans of compressed gas to blow off the accumulation, rather than risking sucking up the cpu chip or fan off of it's zip socket with a vacuum cleaner or poking around with a toothpick. I'm sure it's not chlorofluorocarbon gas in today's environment and the gas is said to be non ozone depleting. DusterT II Compressed Gas Air Duster, 10-oz. Can from Kensington.
