Just installed lights cooling fan and a filter fan into a 8x8x8 T and then out of the Tent, The filter fan is Apx 1100 CFM the fan to cool the lights is about 650 CFM. I noticed the ducting and light fan is hot when i run both because i think the bigger fan is causing an over sucktion and pushing the hot air from the lights partially back into the smaller fan, so the T is not working, I bought a duct clost to a Y shape or a WYE (initials on the piece itself) I know it allows air flow better but i wanted to install it and dont want to install it wrong and end up heating the light cooling fan more and run into damaging it. This is a picture i found on Amazon of the same Ducting, if we call the left side A, the right side B and the bottom hole C, how do i connect both fans and run it out of the tent. thanks.
