There are 4-3" Holes in the back of the stand for powercords and venting. But no fans, im finding that the tank warms up when the halides go out and the 2 4" fans go off (on the same timer) but not too bad between 78 and 79 at most. I also have the front of the stand off alot as im always playing with the skimmer and testing the water right now.
I'll snap some pics later today i hope.
