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.
