What temp you running that thing? Been trying to tune my rigs (290x) and they run hot as hell so I tune them down to keep them at around 85C. You get more than I do per rig.

My MSI R9 280X stays at 82c at 40% fan speed. It's using a small engine overclock (1020/1500 -> 1040/1500), and is mounted in an ATX case with the side partially removed to improve airflow. Multiple cards in proximity would obviously result in higher temperatures.

This has been pointed out before, but middlecoin calculates moving average using your submitted shares. The US East server tends to reject fewer shares, resulting in my moving average showing up to 0.82 Mh/s when cgminer only reports 0.72.

Not fair to compare 280Xs with 290Xs. Let alone the architecture difference, the cooling is significantly different between the two. We have a mix of 280X, 290s and 290Xs in our cluster and 280Xs no matter where you place them, in an open air case or a standard ATX, function significantly cooler with less power requirements and not so significantly less hashing power equaling greater efficiency.

Think you are missing a word or two there somewhere. Cheesy

"We have a mix of 280X, 290s and 290Xs in our cluster and 280Xs no matter where you place them"

I have the reference design 290s, not sure if that makes any difference. Somewhat freaked out that reference designs only have 1 fan.
