My 1 day old Rx 480 8GB GDDR5 shows always a temperature between 40C° something and 50C° something with the fans 99% of the time off no matter the workload despite while using the card for rendering in Vray. My conclusion is something with the temp sensing must wrong which is supposedly very unhealthy for the card when working under high load and fans are at 0 rpm.
It get's even more fishy. I have changed the minimum temperature for the fans to start working to 40C° in Wattmaster. After that, a minute or so later, the fans started spinning for around 10 seconds and then stopped again. After that the started occasionally for no particular reason to work for around 10 seconds or so. Tt also seems that the fans start working when I turn on my PC and then shut down some when in the booting process.
My Gigabyte GA-MA770-UD3, AMD 770, ATX motherboard is quite old, so that could be the reason. But I have doubts that the board is the reason for the error, because the temp sensing and the fans are a part of the graphic card and not the motherboard. And everything else but the temp and fan control seems to work.I have already reinstalled the driver a second time but the problems remains.
Last screen shot was taken while rendering in Vray - so the temp really shouldn't be just 52:
Proposed solutions to my problem are highly appreciated. Thanks!
