Fix Sapphire RX 570 4GB Not Reporting RPM Speed on Windows 10/11

Issue: Sapphire RX 570 4GB Not Reporting RPM Speed on Windows 10/11

Upgrading from Windows 10 to Windows 11 or even within Windows 10 versions, you might have experienced GPU fans not reporting their speed anymore. In this situation, users with a Sapphire RX 470 are forced to run fans at 100%, but find out that fans are not actually running at full speed. This article will help you fix this issue when using a Sapphire RX 570 4GB.

Key Concepts

This article covers the following key concepts:

Identifying the Issue

First, ensure the problem lies with the GPU fan speed reporting and not a different issue such as insufficient cooling, by checking the temperature of the GPU using tools available on Windows. Popular options include:

• Task Manager > Performance Tab > GPU section (default in Windows 11)
• Resource Monitor > Performance Tab > GPU section (Windows 10)
powershell -Command Get-WmiObject -Class Win32_VideoController | Select-Object -Property Name, CurrentClockSpeed, Temperature

The reported temperature should help you determine whether the fan speed is the issue or not.

Updating your Graphics Drivers

One of the primary reasons the GPU fan speed might not report right is the use of outdated graphics drivers. To rectify this issue and ensure the system has the latest compatible drivers, follow the steps below:

1. Visit the official AMD website to download Radeon Software Adrenalin Edition: https://www.amd.com/en/support/graphics/radeon-rx-500-series/radeon-rx-570
2. Select the latest compatible driver version for your Windows 10/11 system.
3. Download and run the installer, accepting the terms and completing the process.

Checking and Modifying System's Fan Control Settings

Adjusting the fan control settings within Windows should help with the fan speed reporting. To check and modify these settings:

1. Windows 10: Open the Registry Editor (Win + R, type "regedit", hit Enter) and browse to:

   HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Control\Class\{4d36e968-e325-11ce-bfc1-08002be10318}\000*

2. Windows 11: Open the Local Group Policy Editor (Win + R, type "gpedit.msc", hit Enter) instead and navigate to:

   Computer Configuration\Administrative Templates\System\Device Installation\Device Installation Restrictions

3. For both systems, look for the ThermalPolicy key within each of the subkeys and modify these values:

• Min Thermal Limit: Set max value to 85.
• EnableThermalMonitor: Set to 1.

These configuration changes improve the chances of proper fan speed reporting within Windows.

Utilizing Third-Party Software for Additional Control

MSI Afterburner can provide enhanced control over GPU properties, thus helping you fix issues with fan speed reporting. You can download the current version from the official MSI Afterburner website: https://www.msi.com/Landing/afterburner/graphics-cards. Use MSI Afterburner for GPU curve and fan control to ensure correct fan speed reporting.

• The problem of the fan speed not being reported on Windows 10/11 can be related to outdated drivers or incorrect fan control configurations.
• Updating graphics drivers and checking/modifying fan control settings, along with using third-party tools, fix issues with fan speed reporting.
