Corsair 900D fan configuration

[Metro]

Hello

 

How many fans would you use with a Corsair 900D, I will be having it like this

 

The blue is intake and the red is exhaust

 

It will be Push and Pull on the radiator at the top

 

What do you think

 

Thanks

Exhaust out of the top and rear, intake on front and sides.

If you use pressure optimized fans for the rad, then you should use them as outtakes, simply because they will move less air out of your case than airflow fans.

Your pressure will be still positive and the pressure on the SP fans will even increase which is good for the rad.

So, front -> intake / top and rear -> outtake

To further explain, you should rarely ever use top mounted fans as intake due to the physics of hot air.  Hot air rises so you'd be fighting physics by having intakes on the top.  If you intake in the front the cool air gets pushed in forcing the warm air to the top and back.  You exhaust there and you get a much better scenario for moving air through your case keeping things at a cooler temperature.

Should I get another 4 fans for the side then or is it not needed, I will not be building a full custom loop for it.

I would do

front-intake

rear-intake

top-exhaust

side panel-intake (optional, since no custom loop probably not a big deal. 4 intake 3 exhaust is pretty good

 

edit: primary reason I would do a intake in rear would be for mobo cooling.  watercoolers eliminate the airflow that aircoolers generate around the vrm on mobo and that scares me.  having a intake blowing on that area will help a lot.  exhaust will not move as much air over the area although it will still have some effect

Well then there would not be much air going out of the case because of the static pressure fans on the top

there is 3 fans on top, one of them not going through a radiator. That'll move more than enough air

I am thinking about getting 9 Noctua NF A14 fans for both static pressure and airflow, that should do it, what do you think, is there any better airflow fans

Yeah there should be tons of threads on that topic that'll be more help than i could be. I just got a fractal design venturi and its stupid quiet, great pressure and decent airflow for 15$us. But those threads would be the best resource
