Hey, I'm not sure if this is the right category or not, if its not feel free to move it.
I just got a computer that, for some reason, the oem didn't install any fans in the case. I just purchased a 120mm fan for the rear vent, there is already a place to put it and everything is ready. I just want to know, what direction should I put it? Should I have the fan blowing air in, or pulling it out?
If it's important, the only other fans in the case are the CPU fan and the power supply fan.
