I got an Corsair ML120 Pro RGB Fan. It has two cables coming out of it a 4 pin power cable, which I know what to do with and can get it powered and spinning. But, it has a second cable that says RGB hub and is a 4 pin female. I have a Corsair Power Node with some lighting strips but that hardware has 3 pin so I don't know where to plug in this 4 pin RGB Hub cable. Please help. Thanks.
