So I mainly have 2 questions:

1) Do I need extra case fans or am I good to go with the stock and re-arrange them into 1 intake, 1 exhaust? or should I purchase say 1 aftermarket 120mm fan

2) Not too sure on how the case fans work. The stock case fans I would need to attach to the motherboard right? The stock fans are 3 pin fans whereas the Extreme 4 has 4pin fan connectors so I won't be able to connect them?

(On pcpartpicker I see people using 3 pin fans on the Extreme 4 such as the Pure Wings 2 140mm so I'm a tad bit confused on how case fans work
For example this build: https://au.pcpartpicker.com/b/6VD2FT uses the stock fans provided with the Extreme4 so I should be alright, maybe?

Thanks!

One additional case fan is a good idea.
You want to have more intakes than exhaust for positive case pressure.
In that way dust gets blown out of the cracks and gaps.
be quiet! Pure Wings fans are a good choice.
I have Quiet Wings fans and they are the best I have owned.
I like them better than my Noctua fans and they are very quiet.
------------------

You can plug 3-pin fans onto a 4-pin motherboard.

On my motherboard I run a detection app in the motherboard control software.
It spins all the fans and finds their control method and min-max speeds.

I'm not 100% sure but I think 4-pin PWM fans use Pulse Width Modulation. Like a rapid on-off switch for the fan.
The width of the square wave changes but the voltage stays the same...

With 3-pins fans, the motherboard changes the DC voltage to the fan in order to control it. Like a throttle pedal.

Depends on how picky you are about having everything match up.

One new 120mm fan + the 2 stock fans will be fine.
Put the 2 stock fans in front and the new one in back.
Two 140mm fans in front will be able to run slower and quieter, plus they will look better.
