Re: cooling an amp (min. Audi content)

I agree that for this application, blowing air across the heatsink would
probably be the best bet--you want to move air away from the heatsink
but with it upside down fans blowing side to side will do a more
efficient job of getting heat away from the deeper bits of the heatsink.
