I just picked up an enclosed reflector with 6" air-cooling flanges. I just ordered a 6" inline fan that is rated to 200 CFM, but it looks like it only runs at 160 CFM. I don't think that'll be enough for my 1000W HPS. My other option was a 424 CFM fan!! That air would be fuckin roaring through the hood! If my nerd calcs are right (Q=VA), then the air would theoretically be coming through the hood at 36 ft/s (25mph). That's a pretty heavy gale. Could that be harmful to the electronics in the lighting circuitry? Harmful to the light in any way? I haven't really seen any guidance on how much air you can pull through these. Does anyone have any personal experience on high flow rates through these? I don't have a carbon filter or anything to really introduce any headloss to reduce air flow (but I'll probably get one once it starts to stink if I have to). So is this fan overkill? I'd like to get a bit more ventilation without introducing another line so I plan on venting my whole room (130 CF) through my hood. Is this 420 CFM torrent of air going to fuck up my light?
