I've had nothing but issues with my H150i since I purchased my computer. I've been on the phone with Corsair. I've gone through all the plugs 10 times over I've uninstalled and reinstalled the app 10 times over this video should help you the y splitter that is provided with corsair, it is not sufficient for the power that the fans and lcd draw or its a faulty item. Once I eliminated the splitter it solved all my issues.
