That seems a little high to me, It looks like you are not overclocking them (avg 10.9) It should be less than 1%. How are you cooling them?
They are v2 blades, 9 are on a backplane in a milk-crate type open container. I have 3 sickle-flow cooler master 120mm fans on each side, all punching in the same direction. Then the blade running solo has 2 120mm fans on the heatsink, a 140 on the back, and an 80mm sucking air out the top. It's a weird rig, everything is suspended with zip ties and I used folder racks to mount it. I was considering adding an exhaust fan to the top of the backplane, but everything seems "good enough" so I didn't bother. Do you think I need more cooling? I can post pics? I am getting 104gh/s, which I believe is considered good for the v2 blades(?).
