cooling layout for small computer cabinet

>>1193707
If you're going to have 4 high-end PCs then 4x 50cfm fans isn't enough... Especially since the cabinet will be full of PCs. You want something that has high pressure and high airflow to make sure the air flows through the highly obstructed cabinet properly. Of course that means using louder and larger fans. Also keep in mind that there will be dead zones or at least reduced airflow in areas like in the corners unless you specifically have fans there.

It should ideally look exactly like a PC case's airflow does unless you're having one PC exhaust hot air into the intake of another, in which case a cabinet is just a bad idea for you. In take from the front and bottom, exhaust out the top and back.

Intake fans are only good for cooling the components immediately in front of them or redirecting flow.

For optimal cooling efficiency, negative pressure systems usually win in comparison tests. Strategic placement of passive intakes in front of the hottest components also helps.

I read that it should be about 160 cfm per 1kw. What would you recommend?

also, to clarify, these are just bare boards and components mounted straight to a shelf inside the cabinet, there are no enclosures

wondering if i should pick up 2-3 140mm intake fans for the back and use the sides as exhaust
