            Bug ID: 105718
           Summary: amdgpu reported fan speed looks too high (dual fan
                    Sapphire Pulse Vega 56)
           Product: DRI
           Version: unspecified
          Hardware: x86-64 (AMD64)
                OS: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: DRM/AMDgpu
          Assignee: dri-devel@lists.freedesktop.org
          Reporter: shtetldik@gmail.com

I have Sapphire Pulse Vega 56, which ships with two fans. According to this:
https://www.youtube.com/watch?v=3mKSrSluxbM&t=1m25s
in a normal scenario, fans should spin at under 650 RPM. However sensors report
for idle load around 1280 RPM for me, which looks like a double value of the
above:

amdgpu-pci-2f00
Adapter: PCI adapter
fan1: 1281 RPM
temp1: +29.0°C (crit = +0.0°C, hyst = +0.0°C)

pwm1 is set to auto:

sudo cat /sys/class/drm/card0/device/hwmon/hwmon3/pwm1_enable
2

Is this a misdetection, or it's supposed to be like that? Actual fans are
pretty silent.

System: Debian testing, x86_64 (kernel 4.15.4).

i notice the same for my vega pulse.
in ur example im pretty sure the fans are even off.they should at such a low
temp. the rpm information seems to work as long at it goes up. but when the
temperature falls below 55°C the fan are going to stop and the rpm info doesnt
get updated anymore and stays there.

I have exactly the same issue with Sapphire Pulse Vega 56. It also reports some
unreasonably high value (something around 3000rpm) as max fans RPM.

I've found this thread
https://www.hwinfo.com/forum/Thread-Solved-SAPPHIRE-PULSE-Radeon%E2%84%A2-RX-Vega56-8G-HBM2-Wrong-FAN-RPM.
Apparently this issue was solved in windows with AMD driver update.

By the way, after using this card for a while, newer firmware fixed fan curves
that were getting stucks, though top level RPMs still remain like that. But
over time I stopped considering them too high. I think they are appropriate for
the card.

Actually, I've noticed another similar issue. I just got Sapphire Pulse RX 5700
XT. It's also dual fan.

According to this:
https://www.gamersnexus.net/hwreviews/3498-sapphire-rx-5700-xt-pulse-review

The top level of fan rotation (at high load and more performance BIOS setting)
is around 1570 rpm. While sensors report that max is 3200 rpm for me!

And something like 50% load (of the fan) is shown as around 1600 RPM!

So I'd say something is definitely off. It's almost like values from both fans
are added up, instead of showing actual one.

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
above.

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

Here is what I see:

>From sensors:

amdgpu-pci-0f00
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.

You could use UPP (https://github.com/sibradzic/upp) so see what your the
powerplay tables report is the maximum for fanspeed. On the MSI Evoke 5700 XT,
mine reports a FanMaximumRpm of 3200. I believe in the case of the Evoke, that
some benchmarks have shown it can get near 3200 RPM at max speed.

I don't know if the driver impacts the values here, or if this is strictly
based on the BIOS. But it might be helpful to see if that max matches what the
sensors are reporting.
