Hello I have a question. I currently have about 60 servers running with all 3 x R9 290. I use Sapphire and XFX as brand.

1) They run all about 875 khs per card, about 2625 each machine.
2) My temps depend. They are mounted on the motherboard. But I am getting temps from 80 - 94. Is this to high?! When the temp reaches the 94, the speed drops back to 865 or a little lower.

All servers are located in the datacenter with good airflow. But maybe we should consider to change the cassis to get a better temp result.

In short: my question is if the temperatures I am getting are maybe way to high and dangerous for the cards?

Thanks!
