How do case fans work?

[chowderblue]

How do case fans work? do you put some of them so that the air blows into the case and then others blow air out? for example heres a picure i will make
x = fans,    I = Case,     arrows = the way the air is going from the fan
  _________________________

/                                                   x --------->

x --->                                             I

I                                                    x -------->

I                                                    I

I__________________________I

if this is the case then i would install some of my fans to blow inwards and the others outwards right? and whats with the labeling of "static pressured" and such?

[chowderblue]

Also with all in one water coolers, i have to install fans onto the radiator?

 ^ = airflow  

 i

            ^                                                ^

            I                                                 I

      xxxxxxxxxx                               xxxxxxxxxxxx                     <-- fans

Static pressure - Allows pushing air through tight spaces, but less air flow compared to "air flow" fans. 

and yes. You'd need intake and maybe exhaust if you wanted.

Yeah, you do, static pressure fans work well with rads.

but they're not marked as exhaust or intake fans right? they're all the same i just put them different ways?

and they blow upwards right? if i were to install the radiator on the top of the case i would put the fans on top to blow upwards?

[Wolther]

@chowderblue Yep, a fan can be either one. Just turn it around

No problem

Two intake, one exhaust is generally a good setup for case fans unless you're running dual GPUs, have a case without great airflow, etc.

 

Radiator fans generally perform better when pushing air through the radiator, rather than pulling it. Unless you're doing a push-pull setup which, again, is only really necessary if you have a thick radiator.

what? oh boy. so on the bottom of my case i put 2 intake fans? and then if i install my radiator and its 2 static pressure fans on top of the case they would push out. this is my build :https://pcpartpicker.com/list/CJWXJV

Linus and JayZ2cents agree, as well as others, that push or pull does not matter. Pull is easier for cleaning. Tot mounted fans should always blow up, you dont want to fight convection (heat rises).

Nothing I said disagreed with what you told me. Why was I quoted?

I misread your post, thought you were saying to use static pressure fans and push through the radiators in reference to OPs  second post. You kind of did in your second post.

Does he have to install a fan on a rad? Yes he does. 

Do static pressure fans work better on rads compared to 'air flow' fans? Yes they do.
