Did some testing yesterday, and discovered that with 16.12.x that while gaming, and I use a fixed fan speed for my testing, that the fans will throttle down, and allow the card to reach up to 93C. Twice this happened, and after a bit at this temp, the PC was forced to reset itself. I was present when this happened a third time, and I had to go into Wattman and force it to raise the "fixed" fan speed by resetting it to Auto, then back to another fixed speed. Then the fans came back on, and cooling was re-established. So either Wattman isn't ready for R9 cards, or our R9's need a FW update to work better with Wattman. On the upside, I ran the game again and left it running all night, and this time it was perfectly fine. Ugh.
