I resecently changed my case fans, however i forgot its positioning, what is the general concept to find out if the fan has been placed for intake or exhuast??
 
Sometimes on the outside there are small arrows that indicate airflow. Otherwise just plug it in and try it before you install them.

most of the time the bladed part is the direction it blows and the motor part is the directionit sucks.
 
Also, if there's a sticker on only one side, that's usually the exhaust side.
 
Are you asking about if you've correctly placed a fan as an intake/exhaust fan as opposed to if you know which way the air will flow when the fan is turned on?

I took it as the first part of the question so I'll say this:

Front panel fan - Intake
Rear case fan - Exhaust
Side panel fan - Intake
Top fan (if case has one) - Intake (mine came as an intake, but I'm not sure if it'd hurt to have as exhaust too)

If you're asking as to which direction fan will blow, they usually have arrows as Shadow said and if not, just turn it on and feel for it. Usually there's a sticker on the middle of the fan and that's the exhaust side.
 
There should be a wire running down one side of your fan. You fan will blow in the direction the wire is facing. But, sometimes the sides will have arrows.

Top fan shouldn't be intake. Heat rises and should be exhausted through the top.

Yeah, that's what I thought and sounded more logical, but it came like that (old Xaser V5000D case) so I just left it. I also figured with the CPU fan blowing toward the rear it'd help get cool air on the CPU then get blown out the back. I doubt it'd make much a diff either way though in my instance.

These fans spread air on both the directions when you being your hand close them then, you will feel air string your hands. So its hard to make out. Today I repositioned my fans, I noticed that even my CPU fan was positioned wrong, the sticker was on par with my TRUE heat sink, I swapped its position. But even after that I see so much air striking my hands, its hard to make out if its intaking or exhuasting. Anyways thanks for the help, despite repositioning my Minimum CPU temprature at stock speed is 36 Degree.

Is it fine or something still wrong??
