The h115i includes a sata to 2 fan header to power the pump and the pump controles the fans just plug the single pin header from the pump to the cpu header on the motherboard and the 4 pin pump header to the cpu opt or chassis fan header and plug both fans into the female fan plugs attached to the pump I know I have this exact AIO if u do not have a sata to fan header adapter u can also use a molex adapter but that's how it has to operate because the controler is built into the pump
