Im currently designing a external case for my WC. Is it better to have positive air pressure or negative air pressure? This case will be a sealed case. Im using 2 120mm deltas( cant find anyspecs but judging by the amps I'd say about 85cfm each) that will be for the radiator.
I was planning to utilize some of the crap I already have and use2 80mm fans(34cfm) on the case. Because of the cfm differences there will obviously be a inbalance in air flow. If this will be a problem I can get 2 120mm fans to balance the air flow. If it isnt, which is better? I would think pulling air through the radiator with the 120mm fans and pulling air in the case with the 80mm fans causing negative pressure would be better.(no build up of warm air).
Tks.
