STUPID FAN QUESTION..

[WangoZ]

What is the front and what is the back of a fan?? I have 2 fans for the front of the case, 1 out of the back as well as the power supply fans..I also have an opportunity to put a fan in the clear window of my case..Where there is currently one of those big ole "tubes" to bring air in or out, over the processor..
But, I know I need to draw air IN the front, expel it OUT the back..not sure about the side,
and I have an XP-120 with a 120mm fan on th CPU..Just not sure how I should palce all this air including the 120mm on teh xp-120!!

spin the blades with your finger and feel whcih side has air coming out of it i think its the side with the supoorts( atleast for my fans it is)

There should be a pair of arrows molded into the outside of the frame. One denotes direction of rotation and the other denotes air flow direction - need to look under good light as they are sometimes not very distinct. Usually the label is on the side where the air comes out too.
