Mine does 756 mh/s @ 52 C,only because of my room being 80 F...........

They were designed for room temps of 72 F or cooler,which is pretty stupid considering
most folks buying these were/are going to be running them in a basement/garage/bedroom.....not in datacenters

So,figure anywhere from 750-896 mh/s at best

Not necessarily stupid, as most people will comparison shop this device at the top performance level, not the expected level for their given environment.
If their sales are higher because of this, then they have made the correct decision.
