I have one fan that is making some highly annoying noise, and when I opened my case today to fix it, I noticed the two extra fans were not put facing the same direction.
For example, in one side, the Antec logo would be facing the inside of the computer, and on the other fan, it would be facing outside.
Is it supposed to be like this? I noticed one fan is 99% covered in dirt, while the other one had no dirty at all.
I'm guessing they are supposed to be like this, so one takes air from outside and drags it in, and the other takes the air from inside and expells it.
But then again, the side which they rotate could be controlled by the cpu, so, I donīt know.
