Oh that tiny fan I was just using to blow air on the stems a bit to strengthen them..Just above it is a 120mm fan that sucks the hot air out the top & a intake @ the bottom
Its pretty air tight when I put my hand over the intake you can hear the whole box suck inward..lol

But yah this morning I tookem outa the box & now their in a closet/area of a closet thats maybe 2x2 not even that
I'll check temps to see if it stays a bit cooler if it dont I'll put them back into the box and leave the top off to vent the hot air & keep the big fan blasting air on the bulb..
