RGB headers and fan help

[xXinsert_edgy_name_hereXx]

I am planning to buy this motherboard https://www.asus.com/gr/Motherboards/ROG-STRIX-B350-F-GAMING/

and this case http://www.coolermaster.com/case/mid-tower/masterbox-lite-5-rgb/

The motherboard has 2 rgb headers, but the question is: Do i need 1 rgb header per fan or i can just use 1 header for the set of 3 fans?

Because im also going to use an rgb radiator which is also from coolermaster.

You can use an RGB splitter for just 3 fans. If you're buying from cooler master it will come with a 1-3 splitter for the pump and 2 fans.

No. You can buy it from retail. Sorry about my poor choice of words there.
