corsair h115i

I am building a PC and using Corsair H115i platinum AIO and have come up with the below wire (in the pic)...Please could you tell me where does this connect to ? System Specs: AMD Ryzen 7 3800X Corsair H115i platinum AIO Gigabyte X570 AORUS PRO WIFi NZT H519 elite Gigabyte GeForce RTX 2070 SUPER

I just replaced my I7 7700k and Asus Motherboard with an i7 9700k Asus Strix Rog Z390-e Gaming mother board. I also replaced my Corsair H100i Cooler with a Corsair H115I rgb Cooler. I was having doubts replacing anything because my PC ran like a champ, but I thought upgrading to the 9700k...
