That is sweet 7th1der! +rep for the awesome creativity. I actually tried making something last night out of cardboard but will most def make something like this in the near future. Would this work for a few passive intakes? I have a lot of negative pressure in the room so when the door is sealed shut there is major suction going on. Let me know what your thoughts of this light proofing technique covering a passive intake are. Thanks a lot man

Thats nice.. The only possible little improvement would be to paint that inside chamber that difuzes the light black instead of white to lessen the light thats bounced arround in there but it may just be overkill. In a dark room is there any light at all leaking?

I think it would be good for passive intake. I had passive at first but my exhaust was too strong and it wasn't doing anything for my temps. good luck! and thanks

In the list of materials he says black spray paint so I'm pretty sure that he painted the inside black. In the last picture you can see the black through the fan blades.

Yeah but the 1st picture you see the outside of fan and can see white through the blades. I just suggested it as a possible improvement however I am not sure how nessesary or benifical it would be. Its well thought out and nicely done allready.

No leakage but with without multiple coats of paint you may get a slight glow.

Thats because thats a picture looking through the fan before the vent. Look at the last picture with the vent attached.

Allright I see it now..

I will be useing this design you have so nicely layed out for us. You were ahead of me on the black paint I just didnt see it i guess.

In the last picture that little knotch thats open is where the air is comeing in. Putting a board at a 45 degree angle above that hole will also help to difelect some more light and spread the cool incomeing air over the bottom more evenly. The top of that board would be white and the bottom black.
