so ive setup my h80i but for some reason i have had to plug on of the fan power cables into my motherboard and i now cat run the other one, now all the videos i have watched show them pluging the fan power cables into the y shaped cable tht has 2 connections on one end and the other end goes into your cpu fan pins and a sata power cable, but i can not for the life of me work out how those fan power cables are meant to connect to the spare to connections on the y shaped cable.
