yo HR, sorry to hear about the temps but i have a suggestion for your ventilation, also what is your fan rated for? here is a pic of the way i have my ventilation ran (we run the same watts), i noticed running anything more than 2 in a row causes the last ones in the row to be REALLY hot, as soon as i switched up to only 2 in a row my lights ran much cooler, just a suggestion.

Azamax is amazing. I suggest Neem oil, too. I hope your heat issues cool off.....HA! (I'm really really high right now) There has to be blockage somewhere if you are having heat issues with that many fans. I'm certain you already know this but, for clarity's sake, you should be taking air out faster than in..... I haven't read the entire thread, but do you have a page explaining your venting setup? If so what pg #? If not, how do you have it hooked up? I second not having anymore than 2 lights to a fan... 1 6" wind tunnel works perfect in my 5x10 with 2x1000w HPS.

I can see your problem already. You've got the 8" sucking air from inside, through the scrubber, and pushing it through 4 hoods. You should be pulling micro-filtered air from outside, in through your hoods, pushed outside to a carbon filter. Even with 4 hoods on 1 8" fan, you shouldn't be where you're at temp wise. I've never liked the conventional "scrubber" with it being in the tent. It forces you to push the air though the hoods rather than pull it. It never has made sense, considering most people aren't using cool tubes or pressure sealed hoods.... Besides, temps drop when you introduce fresh cool air, utilize it, then exhaust it, not just use exhaust all the hot air in the tent. Gimme a bit to MSpaint up a diagram of my venting.

This is how my tent is setup. Very consistent temps at 77*F The HEPA has filter air coming in and washes the fresh air from the bottom, up, across the whole garden before being sucked up n out via the vent towards the top of the tent on the opposite side of the garden. I always have my fan pull from the hoods to the filter because, then, no matter what you are creating a negative vacuum in your tent. If you try to push the inside air through the hoods and out, you will always create positive pressure. If you suck the inside air out through the hoods, you will always create negative vacuum. The carbon in the filter should do it's job whether the stinky air hits it from inside or out. I hope this helps you win your battle of temps!

*EDIT That's a 6" inline for my setup. I was referencing your situation.

no prob, i had my lights running the same way before i changed it but the inline fans are so much more efficient on the suction side because any leak in your venting will be blowing heated air out but when sucking the air any leak will be sucking air anyway so it wont hurt anything. when mine was pushing through the lights, the glass covers would push out small amounts of air aiding in the heat to the room temps got up to the 120's lol once changed to sucking through the lights they dropped back down to the 75-80 mark.
