Well, right now, the eVGA board shows my 4000+ (at 2700)
as 12*C while under Prime it only goes to 18-19*C. My ambient is about 16.7*C, so the sensors are funky. When I had the same setup temporarily on my DFI, I could get it to max temp of about 26*C at 2800mhz. It could also be that the CM Mini is running in my Stacker with the side panel off while I mod it for 120mm. BUT, there's the CM customer service issues
