I know you cant see it in the pic but the fan is a small squirl cage that blows out the back. It's not a closed system the air comes in the bottom also out of view I believe(wrong bottom right) thu the tube and out. it's in a dark bedroom, if you were going to ask about light leaks.whats the point in having a cool tube if it's not being vented to the outside of your cabinet? you should have air inlets and outlets to keep your temps down.
