Hm, it could be radeon-profile mis-reporting fan load percentage, using the max
value of 3200 reported by sensors. That's where I got those 50% I mentioned

I just run The Witcher without vsync (Wine+dxvk) which loads GPU almost to 100%

Here is what I see:

>From sensors:

Adapter: PCI adapter
vddgfx:       +1.12 V
fan1:        1892 RPM  (min =    0 RPM, max = 3200 RPM)
edge:         +76.0°C  (crit = +118.0°C, hyst =  +0.0°C)
                       (emerg = +80000.0°C)
junction:     +94.0°C  (crit = +80000.0°C, hyst =  +0.0°C)
                       (emerg = +80000.0°C)
mem:          +88.0°C  (crit = +80000.0°C, hyst =  +0.0°C)
                       (emerg = +80000.0°C)
power1:      182.00 W  (cap = 195.00 W)

From: /sys/kernel/debug/dri/0/amdgpu_pm_info

GPU Temperature: 76 C
GPU Load: 99 %
MEM Load: 50 %

So the fan shows around 1900 rpm for full load and 76°C. That is closer to 1570
rpm described in the Gamersnexus review. So may be it's correct?

It would be good to get some input from AMD, from those who know something
about VBIOS and Navi firmware.
