When the warm/hot weather arrives (now), I usually find my processor fan 
periodically switching to overdrive.  In the past, I used a straightened 
paper clip to 'pick' out the lint between the fins.  I just did my check; no 
lint, but probed the fins anyway, then started up the computer (with case 
cover and duct removed and blew out whatever was inside.  Seems to be 
running cooler now with no overdrive.

Relating to the OPs post, I once read somewhere that blowing compressed air 
into a computer would place a static charge on the innards.  I do wear a 
wrist strap while cleaning the fins, but wonder about using compressed air.

What do you think, Jan?
