Exhaust T6 is quieter inside tent, than out.
Filter inside tent, ehausting filtered air or filter external with T6 internal.
Space shortage may require less efficient installation.
Exhausting filtered air into lung room retains heat (vice exiting to outdoors).
I drop temp faster exhausting to outdoors or shift to retaining exhausted-filtered air and mix with open windows. Regulating windows or air exchange.T6 speed 4 @76F cools and drops to 75 quickly.
All fans run 24x7, speed 1, lights off and as needed (under 5) for lights on.
Good growing to you.
