That's a bit strange, on account that it explicitly states "GPU Monitoring" on that page. It came about in the discussion of the K-series... I asked if the new cards could have their temperatures monitored, since the older ones could not. Then I was told about smi, and that yes, in fact, you could monitor the temperatures on previous cards.
Now, as I mentioned above, I was told that smi was for Linux-only, but possibly I misunderstood. I'm wondering if temperature monitoring, for some reason, is Linux-only, and that's what he meant.
But that makes little sense.
