help over heating problem

I had the same problem. First thing I tried was replacing the four cooling fans with the ones that intank sells. That fixed it during the winter when the room temp was cooler. Summer was still a problem though. Eventually I have up and bought the led pro hood. That completely solved it. You could also look at the rapidled retro for the hood you have. It's cheaper and has more spectrum than the jbj.

I also put a fan over the rear chambers which worked but was noisy and my evaporation was way higher and hard to control. Krazie
