ok, so cab will be about 3'wide, 6'tall, 2'deep

basically, i'd much rather use my hps for my flowerin cab than cfl's, BUT i need to make the cab quiet, SILENT would be best.

so i'm thinking, a cooltube, exhausting out the back with a pc fan (92mm or 120mm), on a variable-voltage wallwart.

plus another 120mm fan for regular exhaust at the top of the cap, with just passive intake holes all along the bottom back


here's my question: i really don't know how much heat the hps will put out, i've got it on the way from insidesun. am i going to have to run my cooltube exhaust so loudly that it is noticeable? ideally, what i'm going for is for someone to be in the room, and not hear it


LOW-PROFILE is what i'm aiming for, and i'm not sure if i can handle the heat of hps or not
