\_ SMTP quoth Christopher Bardin on 2/12/2003 09:02 as having spake thusly: \_ \_ Newer computers dissipate so much power that they require forced \_ cooling. The cheapest cooling solution is to blow ambient air into \_ the computer with a fan, air inevitably containing dust which, for \_ some reason I can't explain, settles out of the air and coats the \_ innards of the computer. Possibly ambient electrostic charge. \_ You could use a computer as a pretty efficient air filter. I clean \_ the dust out of my computer twice a year, using the exhaust of my \_ vacuum cleaner as a blower, and I'm always amazed by the resulting \_ cloud of dust. Bah. I'm on a pretty much 2 month cycle of applications of the leaf blower. I don't know where all the blasted dust is coming from, but I do know that the leaf blower makes it go away. Maybe the new carpeting (long story) will help and duct filters on the output in the room will help. David
