I have the exact same issue and have had it for a couple of years - did not dig in to figure it out because I'm not a gamer. Very annoying if streaming video or doing anything at all, really.

I can add to the descriptions above:
If you set the fan speed manually with any tool (I only yesterday downloaded Afterburner and confirmed what I found with Radeon software): at 83% fan speed manual mode set, no fan speed (if it is running, it is very low). At 84%, fan kicks on to 100%. In fact, if I let it sit at 83% fan speed request for a long time, it might ramp (maybe for a different reason. This happened once.) But if I set it to 84%, it goes 100%, and cools the card way down. If I then request 83%, it will keep running and oscillate a bit between full speed and something a bit lower (going by sound, because it isn't actually running at 83% or 84%, I don't think). Request 82% and it is off.
Normal use, it is kicking on with GPU temperature as described above - 80C or whatever is where it finally hits the 84% request or higher and fan starts screaming. The temperature climbs fast, of course, when the fan is not running. So it kicks on, runs a few seconds or 10, then kicks off. Very loud, very annoying.
The latest Radeon software doesn't give me options for Wattman or changing curves or target temperatures, I don't believe.
I'm to the point of buying an NVIDIA card if I can't get an update. Which is crazy, as this card seems to be fine for what I do but I don't need to be murdered by my wife for loud fan noise.
Is there a fix for this? I've done all of the driver updates, etc. I've done things to keep it cooler - limited video ads running, etc. But this should not be necessary. If the fan would kick on at intermediate speeds, it would not get hot doing what I am doing - not a gamer. Could the fan/shaft be physically sticky?
