Corsair H110i is good to go right out of the box. It uses the clips on the side of the socket rather than a plate, so is fully compatible. My 1800X seems to max out at around 46.5 degrees C when running at 3.85GHz(100*38.5). As a result, I will bump it to 3.95GHz tonight and see where the temperatures end up. The ONLY reason I have been sticking with 3.85GHz is to keep the fan noise down, because it got a bit loud the last time I went to 4GHz, which was on 0902.
