A lot of people say use a 3rd party TIM rather than the one that is pre-applied. Something like the MX-4 will shave a couple (even a few is you are lucky) degrees off the CPU core temps. The biggest difference will come from using a bigger radiator. At those voltages, a dual radiator will be better.
I'm assuming you are using the fans in push pull. What temps do you get at the moment @ load?
i got a H80i rather than a H100i because of my case (Silverstone Fortress FT02)
my temps are 80-81 degrees (maximum) using AIDA64 and 92-94 degrees (maximum) using IBT
