So I just bought a new case and it should be here Tuesday. The case already comes with a 120mm front intake fan and a rear 120mm exhaust fan. the case allows me to put up to 4 80mm fans on the side and I just purchased 2 80mm cause I wasn't planning on getting the money for the new case but I did so yeah. now I'm gonna have 2 brand new 80mm fans to throw into the case. my question is should I have them both as intake or both as exhaust or should I do one intake and one exhaust? thank you in advance
