           Summary: amdgpu: XFX Radeon RX 580 runs its fans only in

In Windows AMD drivers like to ignore VGA BIOS fan control settings along with
their own "Wattman" and disable fans until core temperature starts to go near
50-60 degrees, even at full load fans don't go over 2600 RPM there BUT on Linux
they get stuck at 800-900 RPM by default (if pwm1_enable is not tempered with),
at 1300-1400 RPM if pwm1_enable is set to '2', at 3500 RPM if it set to '0' and
only manual control of '1' works as expected. temp1_* settings are outright
ignored with error "permission denied". Unless manual control is used, GPU's
core may overheat to >70 degrees (I don't even want to know what's happening on
VRMs) at >90% load. This is madness.

In Linux on idle (~0% load in radeontop) GPU doesn't go lower than 41 degrees
even with 1300-1400 RPM on fans, even though under Windows it goes to 35-40
with fans completely off (which I don't want to allow anyway because I don't
know how safe are VRMs).

Easy way to overheat it is to use 'FSRCNNX_x2_r1_16-0-4-1.glsl' from
https://github.com/igv/FSRCNN-TensorFlow/releases with a ≤720p video.

more aggressive cooling and lower frequency than stock.

Same thing with 4.17 kernel. It seems that any kind of fan speed control is
happening only when pwm1_enable were completely untouched and there is high GPU
load. However, it never changes memory frequency, so on idle it reports 40-44W
of power usage instead of 12-15W on Windows. Now, in the middle of hellish
summer, GPU temperature quickly rises from cold-boot 35 to 50-55 and stays
there because of all that. Even my crappy FX-6100 CPU with 9mm fan isn't that
hot on idle.

Same bug with 4.19.16 and Strix RX 470.
