I have a 6870x2 which has 2 GPUs on one card. The two GPUs are seen as two different cards, one with a fan (gpu1), one without (gpu2). If gpu1 overheats then the fan ramps up as expected. If gpu2 overheats the fan doesn´t change. The two GPUs are sharing the fan so should both contorl it's speed.
My hope is that ADL somehow distinguishes that two GPUs are on one physical card, and we can use that to use the MAX or the AVERAGE of the two GPU temperatures for temperature control...
