Fan controlling without Fan Control

[necromancher]

Hey everyone i got a small problem figuring this out.
So the thing is that i am gona put a 3ple rad with 3 fans on my system and i want to control the fans individually or at least the rad fans as a pack.But i got 4 extra fans in my system for good airflow.
So my mobo has CPU_FAN and CPU_OPT 4pin headers and on of them is going to be used for the pump.And CHA_FAN x 3 4pin headers.
If a use a pwm splitter like this : http://www.ekwb.com/shop/accessories/cables/ek-cable-splitter-4-fan-pwm-extended.htmlwill i be able to control each fan connected to the splitter individually as it is claimed on the specs of the splitter.Beacause if i am gonna connect the 3 rad fans and one other fan of the system to the splitter i want that fan to be controlled apart from the 3-rad-pack.
If this isn't my solution what can i use instead?A fan hub would do the job?LIke phanteks or Grid+ from NZXT?
Ideally i would like a fan hub so i can upgrade my system with a second 3ple rad and control again the 3packs individually.

 

Thanks for helping me sorting this out.

 

p.s A fan case control solution is not at the table right now due to budget problems .

 

p.s2 All the fans are pwm right now but non-pwm solutions are acceptable
