"I fixed it. It was indeed the Y splitter that came with the h75. I hooked the top radiator fan to the top fan header and the bottom radiator fan to the cpu header. Then in alienware command center I adjusted the top fan to sync with the cpu sensor. Thanks for your input!"
these 2 solutions seem different to each other. I cant work out whether the second solution used the Y splitter or not and there is no mention of the pump wire and where that should go?
