I picked up a couple of hard drive fans at Dayton for about a buck each. They are 
already are mounted in pairs and the right size to cover the most"active" half of the 
heatsink. Wired in series they run at a nice steady rate and don't cover the speaker at 
all. I agree with Ron about sound deflection - makes a big difference as does a resonant 
tube over the speaker for "free" filtering!
