    Hi,
    Running 480W QB Leds. In a 4x4x80" tent. Will a 4" exhaust fan with carbon filter be enough? Tent is on living area of my house but may be moved to garage/basement.

    Tks.

    No.
    A 4 inch fan isn't enough for my 2 x 4.

    I did one run with a 4" in my old 4x4 tent. 6" is a much better choice. The 4" ran at capacity and I don't like that. No wiggle room. Go with the 6".

    Get at least a 6 inch and put it on a speed controller. I use a 8inch Can max fan pro on a controller in a 5x5. I usually run it at 40% which provides plenty of negative pressure and the fan is almost silent.
