Cool offer for the forum involvement - Happy to help if selected Mishima.
I run a H50 with push-pull fans and the radiator outside of my case - pretty easy to swap the fans and try just push, just pull, both with other fans.
I also have 2 exhaust fans on the top of my case extracting air from the H50 rad push pull... and a front intake fan
My case is a thermaltake v3 - a mid-tower case, and on the small side so needs some air through there.
More than happy to report on noise, temps, game temps, oclock etc.
