Version 3.0c. Fan control seems not to be working properly.
Environment:
Clean installation Windows 10 (1709), no updates.
Drivers - latest (18.6.1)
Card: single Asus ROG Strix RX580 O8G (stock bios, only timings modified)
No any additional software than can interfere with fan control is installed (like Afterburner etc.)
-fanmin 50
-fanmax 100
-tt 55
When miner starts - fans are initially stopped. When temperature rises to 50 and above - fans start working on max speed (maybe not max but high enough). In a few seconds temperature drops below 50 and fans begin to slowdown and finally stop. In a few seconds the sequence repeats.
Tried setting -tt -50 to force constant fan speed - not working.
At the same time it works on Asus Strix RX570 more or less properly. At least asjusts fan speed to keep temperature set by -tt.
I have compared bios bios fan settings for these two cards - they are identical.
It is incompatibility with this particular card or I am missing something?
Have you tried control fan speed using any other software, e.g. Asus gpu tweak II?
Command -tt -50 should keep fans at 50% but that GPU has a thing they called 0dB technology and it starts fans at 55°C and stops them when temperature drops below that value.
Maybe you should try -tt -30 to keep fans at 30%, that way GPU should be above 55°C and fans would be spinning constantly.
