Hello again! I'm will be using a building with the NZXT h500 as a case which has 2 dust filters for the fans, one in the front and one on top. The case comes with 2 fans (one in the back and one in the top). What's the ideal airflow? I'm thinking of buying two extra fans and put them in the front, while I will have 1 fan in the back and one in the top working as exhausts. Is this a good idea? Saw a video in youtube and the guy was saying that its better not to use exhausts so that the graphics card and the CPU will be also "breathing" from the back and the top of the PC to reduce temperature. Is that true?
