Cyknight Posted May 26, 2021 Share Posted May 26, 2021 If you must built one (and it really isn't recommended to anything that enclosed) best bet is probably two fans/fan rack mounts in the back, one at the top blowing to the front and out of the cabinet, one at the bottom to pull air in.

C4 User Posted May 27, 2021 Share Posted May 27, 2021 I have a 4 x 10 AV closet. All my gear is in this closet. I have two 0-10v continuous duty high efficiency fans, one inlet, one outlet. I wrote quick routine in C4 to manage fan speed based on temperature. Works great and keeps AV gear cool with fresh air. Now my inlet air comes from a room that is kept at a constant 72 degrees. And you will want to return the air to the same space you take air from so that you do not create a negative pressure in your house. Quote Link to comment Share on other sites More sharing options...
booch Posted May 29, 2021 Share Posted May 29, 2021 I'm using an AC Infinity Cloudline fan (located in my crawl space) that ducts through a vertical wall into my rack -- works awesome. Pic for reference below. Quote Link to comment Share on other sites More sharing options...
Neo1738 Posted May 29, 2021 Share Posted May 29, 2021 How do you prevent negative pressure from slamming door to closet, just keep it closed let air under closet door flow in or have a extra hole somewhere? Also what is that you found to put on top of the cabinet? Quote Link to comment Share on other sites More sharing options...

Most fans like the ones mentioned here aren't going to pull that much - does your bathroom fan require something to prevent neg pressure?

When the amps are cranking, this closet takes about 400 to 500 CFM to maintain temperature of 80 degrees with intake air no higher than 73 degrees. I use two in-line ducted fans, one for inlet and one for outlet to keep the pressure balanced. Quote Link to comment Share on other sites More sharing options...
