Well, I originally had the H80i in my Prodigy build, later I found out it had some damaged fins on the Rad and with proper thermal paste it was idaling at 47c and on load 80c...I ended up taking it off and put the H100i and added the IC Diamond now I got a 10-30c decrease in temps and the performance got better :3
The only bad thing is the IC Diamond comes out super thick had a hard time applying it.
