RGB fan control help

[Raimonds M]

Hello.

Recently I acquired myself a used case, CORSAIR Carbide Series SPEC-DELTA RGB Mid-Tower ATX PC Case , I got it used so no chance of returning.
As a fool I did not check that I don't have RBG Control slot on my motherboard -  Gigabyte GA-Z170-Gaming K3, Z170.

Tried to find out how to control the fans myself or get an controller but there is so much different versions. 4 pin, 5 pin, 6 pin. 12v 5v. Very confused.
Can i get 6 pin controller and if i plug 4 pin fans will they work?
I know that this case has 4pin 12v fans? I had some ideas like to get these to, RGB Fan controller hub and RGB controller  but looking into it, looks like they cannot be plugged together.
Don't have a big budget on this. 

Is there anybody who could point me the right way, really want the flashy lights on my case 

EDIT: I will try out this combo and hope it works. This one + RGB controller  Can anyone confirm if it works?

Thank you.

Raimonds.
