Need help with Corsair h110i GT

[suprx_]

Hey guys!
I just got my nzxt noctis 450, and when I was trying to mount my 280mm rad in the top. It doesn't seem to fit so well, I can only get a couple of screws in, any solutions?

Use zip ties. That is how I installed my H110i in my Rosewill Throne case. I experience no vibrations or added noise from them.
