I want to install a couple 120mm fans in my case, but I don't really know which way to install them to get air flowing in the direction I want. How do I tell which way I should be installing it?
Yeah, I'm sorry dude, the answer is so obvious, that I'm not surprised some thought you were kidding, lol.
Anyway, I'd like to add to the helpful answers, here. You can tell:
- Apply power and put your hand in front of it. One side it will obviously be blowing and pushing your hand away. The other side will be doing the opposite and will suck your hand in. Of course, be careful not to allow your fingers to snag in the fan blades, as that can damage your hand and the blades
- Most, if not all, have two little arrows embossed on the outside edge of the frame, at 90 degrees to each other. These indicate the direction of rotation and air flow.
- EDIT: and what Depth said, below. Very obvious indication
I think an equally important question is about balancing the thrust from the front fan and the others in the case. I believe that the should all be the same, in order to avoid creating high and low pressure spots inside the case. I'm not 100% sure on this, so I'd be grateful if someone could clarify.
And finally, what do I do? I run my PC 100% of the time with the side panel off, so the only case fan I have running is the front one for the hard discs.
