Corsair Link usb needed to be connected for the pump and fans to run?

[XXXXXXXXX9]

My motherboard has only usb 3 header so i need to buy an adapter for usb 2, but in the meantime can i use the h100i v2 cooling system without the usb corsair link cable?

shouldnt stop it running though might lose some functionality of the link software

I have a Corsair h115i liquid cooler AND a Corsair hx850i PSU. I ran out of USB headers (I needed one for my front USB 2.0 ports and one for my Bluetooth) Out of desperation, I took two regular USB cables that I had laying around the house, connected them, one to each unit, and neatly routed them out of the case to my two free USB ports on the back of the computer and everything works fine with the Corsair Link software. Let me tell you, I was soooo happy to finally have control of my pump speed and rad fans!!! It seems absolutely stupid that Corsair wants to monopolize a whole header for their silly 4 wire plug, but that's what workarounds are for..... Best of luck!
