Caporegime
Have you tried lowering the P6 and P7 voltage by 0.050mv? That may help reduce the temps and result in a slightly higher clock.We've tested it, the VRM temp has reduced, the card held around 1570-1590MHz for a solid 30 minutes roughly before it started to throttle back, so it helps but due to the Asus fans been so quiet, eventually the card heat soaks, as even 100% fan speed they are still quiet.
I think it is quite simple if you want best performance, you buy Nitro or Devil.
If you want silence, reference levels of performance and good looks with good warranty you buy Asus.
