Micrornd Posted August 20, 2013 Share Posted August 20, 2013 I'm assembling the workstation in my profile currently and have a question that seems to have several different answers. The directions that came with my H110s are very clear - Connect the pump to ANY 4pin or 3pin fan header on the MB (with pictures) And the pump has a standard 3pin fan connector with all 3 wires attached. Yet here in the forums, it is stated that the pump should be connected to 12v, and not a variable voltage or PWM fan connection. Yet in all the reviews I've seen online, the pump was connected to a CPU fan or a MB fan connector, and no mention was made of the pump needing a steady 12v or that Corsair had contacted them to indicate it was needed. So what is the real deal? Why does the pump have a 3pin fan connector on it, if is not meant to be connected to a fan header, and not a std. 4pin molex connector for a constant 12v :confused: And why does the 3pin fan connector attached to the pump have all 3 wires in use, if only 2wires are to be used to connect to 12v :confused: Link to comment Share on other sites More sharing options...
