Mine are in cases but the cases sides are open and they have tons of fans - those are aluminum lian-li cases. In the smaller case they are 83/82, fans at 90/92%, larger case 74/80 fans 77/80%.

A single card runs around 60 to 70 something with fans at 50-70...

I don't understand why hash rates drop so much though... They are 620/730 and 630/720... The cards are very similar and i tried switching them around with no results... Let me know if powered risers make a difference.

Yeah, I've a funny feeling that the mobo cant provide enough power. Powered risers can push the extra 50w+ through the molex.

I was hoping they would turn up today but the postie has been and gone now Embarrassed
