Evga is top notch. And anything in life there is problems I had a titan x die on me they sent me a rma one doa. They took care of me and I didn't give them attitude it happens.
We all have bad days and things go wrong. And the Nzxt h700i or h710i is a ok case for air flow. It's really good with out the top and front panel on temps will drop 5-10C.
I have noticed in my old h700i that my 3000rpm fans even at 60% was dumping so much heat out of the case that it was like a heater. Switched to a different case with more room and my room temp doesnt raise by 10-15 degrees anymore.
