Blowing air onto the PA allows you to put a filter on the fan input to catch
dust and dirt. Doing the reverse pulls unfiltered air into the PA and you can
get a big pileup of junk on the PA. (Including and occasion bug or two).

OK, this sounds like a simple question, but I can see advantages to both
solutions.
When adding a Fan on a PA heatsink, should I be moving new air in blowing it
onto the heatsink? Or is cooling more efficient when the fan pulls the
heat away from the heatsink?
Thanks in advance,
