Which way round to position pc fans

[Dpower]

Hi, this may sound kinda of stupid but which way round do i fit my pc fans.
I am aware that the back should be an exhaust and the front an intake but which way do i fit them?. So which way should the logo face inwards?
I am new to pc gaming and have just recently build my pc, but just cant figure out which way round my fans go.
I have a NF-A14 PWM and a Noctua NF-S12A PWM .
Thanks

Front, Side, Bottom (if any) ---> Intakes

Rear, Top ---> Exhausts

I am not a fan of 'Positive pressure' or 'Negative pressure' because the air inside the case and outside the case is of the same quality as far as cleanliness is concerned.

Computer cases have screens, not filters - a lot of dust gets past these screens. Regular and careful cleaning using a can of compressed air is recommended.

Well look at the fins, fans spin clockwise so air will travel where it's being captured and pushed through, you can easily tell which way the air will go by just spinning them clockwise with your hand and feeling which direction of the air. If you're looking at the logo then its exhausting the air. for intake the logo should be facing forward so you see the back of the fan and for exhaust you can see the logo. Air usually flows away from the logo, in pretty much every fan anyway.

He knows this he want's to know what way the fans go round, not the position in the case, he want to know how to determine intake and exhaust.

What heatsink do you have and what direction do you have it? A picture of the inside of your case might help, but this is generally what you want.

For the bigger heatsinks, some people prefer this way

Re-read his Q, he knows that he wants to know how to determine what way round they go.

The Air flows away from the logos on the fan.

Just put your hand infront of a fan, you'll feel the air coming out.
