No, all the heat is dissipated in the grow space. I'd only keep about 45W of heat out of the space by mounting the drivers outside. It wasn't worth it to me, when my extraction fan changes the air in the grow space at least three times per minute.And so this stlye of passive cooling allows you to keep the "inefficient" heat out of the grow space...?
There are no boards, and no fans. I suppose you could call the COB (Circuit On Board) a board of very tightly packed LEDs, but then so are the multi-wavelength LEDs used in the Quantums.So there are no fans cooling your boards?.

When you say cob drivers are outside of tent...
This is like the "ballast"?
So your not using one of the pre made board type lights with fans built in right. Im guessing those have all components in the light..?
