Trying to locate the USB header on MB that controls my front USB.

[ScornSnakeX]

I have an Alienware Aurora R3 (Lga1155 046MHW)

I am replacing my factory liquid cooler that came with my machine 4 years ago because of temp problems. I purchased a Corsair H80i v2 liquid cooler, I finished installing everything and last step says to "Connect the USB header side to a free 9-pin USB 2.0 header on your motherboard" as per directions in last step http://www.corsair.com/en-us/blog/2015/march/h80i_gt_how_to

My motherboard only has 2xUSB 2.0 headers and they are both currently being used (came like that) here is the diagram of my motherboard http://en.community.dell.com/owners-club/alienware/f/3746/t/19461681

What are my options are far as possibly unplugging one of those USB headers and using it? Anyway to just disconnect the front USB since I do not use those at all? If so which plug is it in the diagram I could disconnect?

Thank you

#3 and #4 are fan headers

Yes but I need a USB header so my Corsair liquid Cooler can communicate with its software, COrsair link.

Looks like you need to pick between 16 and 17 and lose 1 set of USB ports on the Front. They are both USB 2, so if the back plane USB and 1 set of the front will work for your peripherals, there it is. Far from ideal.

so one of those ports control the front USB (All of them?) and other is back side USB (All of them)? The back side usb ports will be more then enough for my perphels, so which port 16 or 17 for front usb?

the 2 headers 16 and 17, chase the cables. They should go to the front USB ports. The back ones come straight off the MoBo and are not changed by the headers usage.
