NZXT X53 cable setup

[HCKhor]

Need help on the NZXT X53 installation:

 

1) I heard the ideal setting of concurrent AIO pump should set at 100%, so the lifetime is longer? Is it apply to NZXT? Some website indicate that NZXT X53 is designed as "variable pump speed"? Which 1 is correct?

 

2) (i) When the pc builder set up my AIO, there are 2 cables from my Pump (1 is micro USB cable and another 1 is breakout cable). For the breakout cable he set up as below:       

     a) Sata: to PSU       

     b) NZXT RGB: to None (do not owned NZXT HUE)       

     c) 3 Pin connector: attach to CPU_FAN port on MB (please note that I have AIO pump port on MB, left unoccupied)

2) (ii) 2 NZXT fans on the radiator (max speed 2300 rpm): connected to CHA_FAN 2 port on MB, this CHA_FAN 2 port (split into 3 connectors via fans splitter cable, 1 into 3) was shared by another 1 fan on top of the casing (corsair LL120, max speed 1600).

Based on info listed above, is it correct to connect the 2 nzxt radiator fans to the same port (CHA_FAN 2), and shared with corsair 1600rpm fans?

 

3) If my set up as per above, when I go to set up BIOS Q-Fan controller, CPU fan should set to Direct current (DC) 100%?

 

4) I need to adjust fan curve of other chassis fans via Q-fan, when I do this, it forced me to choose setup for my CPU fans, should I choose DC or PWM

Please advise if the setup above is not the best setup.

 

Thank you.
