Noob Question

Because I can't remember:

On an 80mm case fan, you have two sides, the bladed side, and the bearing side (the back).

Which way does the air suck? Towards the front, or back of the fan?

 

If you look at the blades they are slightly curved the fan blows air in the direction of the dipped side so if this bracket were a fan blade ( it would blow air to the right.

 

Noob Answer:
Just hook it up, ya got 50/50 chance of getting it right.








The bracket side and or the bearing side is out, incomming air is from the other side.

 

Not to mention, one of the sides will have 2 arrows. They will be perpendicular to each other. They tell you which way the fan spins, and which way the air blows. I assume you can figure out which is which.

 

I figured it out, but there were no arrows.


Just an FYI.

 

Of course, if all else fails, you could hold it by the sides, and spin the blades with one hand, holding that hand on the other side. If you can feel the air flow, that's the correct side.
