Well even just a hole would allow the heat to rise, but i was suggesting you
add that fan in the blowhole with the air of course blowing up and out. Also
place one of those metal finger guards like you see on the sides of pc's
that have side fans.
My brother has a nice 20 year old solid oak stereo rack and when he added a
dual blowhole into the top of the unit, he was able to lower the temp in the
cabinet by approx 8 degrees.
He lives in a hot area of Utah where the average temp is 80-100 degrees year
round so he needed to do something.
