I have recently installed a couple of fans to the back of my computer, as of now they are both blowing towards the inside of my case. I have one fan on my cpu, and two on my power supply (one blowing in from the outside, the other blowing towards the motherboard. My question is should my new fans (the ones in the back) face in, out, or one each direction, if the latter which one should blow in and which out.
p.s. the two fans are arranged on top and bottom of each other.
