The Corsair SP/AF120 arrived today and I've set them up inside the Zalman Z9 Plus case but not sure if I've set them up correctly as exhausts and intake which will help airflow,

Two top fans of the case,

Front fan,

Bottom fan,

Also on the other side of the CPU heatsink, do I setup the fan the same as this side?

Stand back! Do not disturb the art display!:D

*First thing I notice is how clean and organized everything is. :D
*Second thing is that you case sets so close to shelf there is very little space for airflow.

I've similar setup to the image I've shown you

I would turn bottom fan over and use it as an intake... but I worry very little about exhaust fans. Good intake fans will easily create airflow as long as there are enough exhaust vents to let air out.

I'll turn the bottom fan over as intake which brings air from the bottom to the case?

The computer desk I've shown you, mine has about 7cm on each side where the computer sits on and the computer desk doesn't have the wood blocking the back of the computer

Is my front fan setup correct or do I need to turn if around?

I'm talking about between the bottom of computer and shelf, not along side of computer. Your bottom fan is trying to pull air from under computer. Computer is setting on shelf. Shelf is very close to bottom of computer. :)

The Zalman Z9 Plus case has a bottom stand which has 2cm space for air to pull in

A fan needs at least the same area in the circumference of fan. Simple as can be. You can't move all a 153cm square area (140mm fan) can if the area feeding it is only 88cm square. 88cm square is the area of a 20mm space (feet on you case) around a 140mm circle.

Hope you understand.

Try this and see if it helps you understand. Take your 140mm fan and with it running move it from flat on top of you desk (or whatever flat surface you want to use) and put your face so fan is blowing at it. now lift the fan up to 10cm, back down to 5c, then 3cm, then 2cm. You will feel the difference. The closer you get to surface the less air the fan will blow up at your face... and the louder the fan will sound.

At the end of the day you will do want want to do. And that's fine with me. :)

Very often case design is for looks and appeal, not real function.

I know what you mean, there will be less cold air going through the case as the bottom space is little, what would be your suggestion of the bottom fan? Intake or Exhaust?

So facing the PSU fan up is a good idea,

Also is my front fan setup correct or do I need to turn it around?

=Front and bottom in.
=Back and top out.
=Side of fan with all fan is air in.
=Face fan side of PSU down.
=Set your case feet on top of some 2-3cm spacers... Take feet off and put a 2-3cm spacer on the with longer mounting screw/bolt.

Sorry, I'm a bit confused, should I face the PSU fan up or down? Is my front fan setup correct or do I need to turn it around?

Also can you provide me images of spacers and mounting screw/bolt as I haven't done this before

Did you try the fan test I discribed?

Yes, as I've few Zalman fans with are taken out from the case which I used for the test,

Just I want to make sure that I didn't do anything incorrect which will create a bad airflow

Just few questions that I want to ask before finishing my build,

1. Should I face the PSU fan up or down?

2. Is my front fan setup correct or do I need to turn it around?
