Hi
I want to build my new gaming case. i decide to buy Crystal 570X case.
I want to change stock fans and use Corsair LL or HD series instead.
My question is Which components are needed?
What is Corsair Commander Pro and RGB LED Hub?
Do I need both or only Commander is enough or is Commander Pro necessary or lighting node is enough?

I want install following fans:
3x120mm HD or LL for front;
2x140mm HD or LL for top;
1x120mm HD or LL for rear;

Shall I buy Fans with controller or only single fan without any controller (single pack)?

HD is better or LL?
Can replace water cooler fans with them? be cause them speed is lower than cooler's stock fans
What is maximum water cooler dimension for top of this case? is 240mm or 280mm? if is 240 i buy 120mm fans instead 140mm

The Crystal 570x case comes with an RGB Fan Hub already; the SP-RGB fans that are stock with that case are connected to it.

HD or LL is really up to you and what look you are looking for. The HD fans do have a higher speed and corresponding higher airflow and static pressure but are also noisier. The LL fans are just gorgeous but only show the RGB effects on one side (intake). Depending on how you mount them, that may not be an issue.

The HD fan multipack will come with a Fan Hub and a push-button controller. This will provide limited effects. You would need a Lighting Node Pro or a Commander Pro for the full effects. The LL fan multipack comes with a fan hub as well and a Lighting Node Pro. With the LL multipack, you'll have all...

The Commander Pro is a great devices on it's own; it provides fan speed control controllable from Windows and has 4 temperature sensors that you can use as the control source for your fan curve, giving you pretty granular control over noise vs. temperatures.

Finally, the max top-mount for the radiator is 240mm. You have more options for front mounting a radiator.

Thanks very much.
Another question: If I want to connect 6 fans and without Commander pro (it is very expensive), How to connect PWM sockets? Be cause the RGB Hub is only for RGB sockets

My motherboard has 3 sockets to connect SYS_FAN.
How control fans speed from Windows?

The LL max speed is 1600RPM is this enough for cooling system and replacing water cooler stock fans?

Without the Commander Pro, you would need to use your motherboard's fan headers or another fan controller. Assuming that you go with the motherboard's fan headers, whether or not you can change it from Windows depends on the software from your motherboard manufacturer.

As for whether or not the LL is enough for cooling a radiator ... it depends on the heat load that you put on it. TBH, the ML fans give the best noise/performance ratio in the Corsair line. There are those, however, that have used LL fans for the radiators. You may have slightly warmer coolant temperatures and it may not be as good as the ML fans, but it would work. Personally, I have push/pull with LL and HD fans on my radiator.
