I've got a 20x24x36 cabinet with a pull out mid atlantic rack. A door is present with the little rubber bumpers that keep it from slapping shut. This leaves about a 1/8" crack around the perimeter of the door. Currently I have a double rack mounted fan unit on the top back of the rack, blowing towards the door. In the back of the cabinet, there are a couple of 4 inch holes to route the wires in. In spite of this, it still gets hot enough to warm a small house, so I end up opening the door and every couple of hours.
Any good websites on how to's? Such as quite fans, filtering, fan placement, etc.

Thanks

If indeed the crack is a consistent 1/8" and the door is, say, 22" by 34", then you have the equivalent of a 14 sq. in. hole at the front of the cabinet; plenty for ventilation without even considering the holes in the back. However, blowing air toward the door won't do it. Get the air flow reversed and vent it out the top or back. The fan will need to be flush mounted to either of these to be effective. This will allow you you take advantage of the venturi effect; air that has to pass through a constriction speeds up. It sounds like the fan's current position is doing little more than blowing hot air around.
Good luck!

Yes, as I recall, Mid Atlantic has a "cabinet cooling white pages" that has the ins and out of cooling.

In fact, here's a link to the form that you have to fill out to DL it:

oex, you beat me to it. This is what I have used, and it works great. I bought the system with the individual fans and controller for 4 fans. I cut a slit in the bottom of my cabinet for air intake (using a router) and then cut holes for the fans in the back top of each of the cabinets. Nothing but room temp in all three now.

if the front of your cabinet is shaped like this:

| <----door
|___
|
|____________(floor)


put air holes in the horizontal section
