1 fan header, 2 fans on radiator

[randomname6969]

So im planning on getting a Corsair H115i pro and the radiator has two 140mm fans on it. My Mobo has only one single cpu fan header. Would it be a good idea to buy a 1-2 fan splitter or does the h115i pro come with a fan splitter?

Methinks it comes with one.

The fans are connected to the waterblock,from where one three pin will connect to the cpu fan header. They then can be controlled by the Corsair software by using the usb cable,again comes from the pump,to connect to an appropriate usb header on the motherboard.
