--- Comment #1 from Wilko Bartels me@jasondaigo.de --- (In reply to Shmerl from comment #0)

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.

--- Comment #3 from wedens13@yandex.ru --- 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.... Apparently this issue was solved in windows with AMD driver update.

--- Comment #5 from Shmerl shtetldik@gmail.com --- 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.

--- Comment #6 from Shmerl shtetldik@gmail.com --- 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.
