Are you experiencing the frustrating issue of Macs Fan Control losing your custom fan presets every time you reboot your Windows 10 installation on your Mac Pro 5,1? You're not alone! Many users have reported this problem, where their carefully configured fan settings revert to default after each restart. This article delves into this specific issue, exploring potential causes and offering troubleshooting steps to resolve it. If you're tired of constantly reconfiguring your fan settings, keep reading!

Understanding the Issue

The core problem lies in the persistence of custom fan presets within the Windows 10 environment on a Mac Pro 5,1. Users report that while Macs Fan Control functions correctly during a session, the custom rules and settings they create are not saved or loaded properly upon reboot. This forces users to reconfigure their fan settings every time they start their computers, which can be incredibly inconvenient. Let's discuss the specifications and confirm if this is a known limitation or if there is a workaround.

Key Symptoms

  • Custom fan presets in Macs Fan Control are lost after every reboot on Windows 10.
  • Fan speeds revert to system defaults after restarting Windows.
  • Custom rules and profiles disappear after each reboot.
  • The issue is specific to Windows 10 (booted via Boot Camp) on Mac Pro 5,1.
  • macOS does not exhibit this behavior; custom presets are retained.

Possible Causes

Several factors could be contributing to this issue. Some potential causes include:

  • Permissions Issues: Windows might not be granting Macs Fan Control the necessary permissions to save its configuration files properly. This could be due to User Account Control (UAC) settings or other security restrictions.
  • Boot Camp Driver Conflicts: Incompatibility or conflicts with Boot Camp drivers could be interfering with the application's ability to write to the system's storage.
  • Application Bugs: There might be a bug within Macs Fan Control itself that prevents it from correctly saving or loading custom presets on specific hardware configurations (Mac Pro 5,1).
  • File Corruption: The configuration files where Macs Fan Control stores its settings could be getting corrupted during the reboot process.
  • Service Startup Issues: The service responsible for managing fan control might not be starting correctly or in the proper sequence during the Windows boot process.

Troubleshooting Steps

Now that we've identified the problem and potential causes, let's explore some troubleshooting steps you can take to resolve the issue. Work through these steps systematically to identify the root cause and implement the appropriate solution.

1. Run Macs Fan Control as Administrator

Ensuring that Macs Fan Control has the necessary administrative privileges can often resolve permission-related issues. To do this:

  1. Locate the Macs Fan Control executable file (usually in C:\Program Files\Macs Fan Control).
  2. Right-click on the executable file and select "Properties".
  3. Go to the "Compatibility" tab.
  4. Check the box labeled "Run this program as an administrator".
  5. Click "Apply" and then "OK".

After making this change, reboot your computer and see if the custom presets are retained.

2. Adjust User Account Control (UAC) Settings

UAC settings can sometimes interfere with applications writing to protected areas of the system. Try temporarily lowering the UAC settings to see if it resolves the issue. To do this:

  1. Type "UAC" in the Windows search bar and select "Change User Account Control settings".
  2. Move the slider down one level (e.g., from "Always notify" to "Notify me only when apps try to make changes to my computer").
  3. Click "OK".

Reboot your computer and check if the problem persists. If lowering UAC resolves the issue, you can try setting it back to the original level after confirming that Macs Fan Control is working correctly. Just be aware of the security implications of lowering UAC settings.

3. Reinstall Macs Fan Control

A fresh installation of Macs Fan Control can sometimes resolve issues caused by corrupted files or incorrect configurations. To reinstall the application:

  1. Uninstall Macs Fan Control through the Windows Control Panel (Programs and Features).
  2. Download the latest version of Macs Fan Control from the official website.
  3. Install the application, making sure to run the installer as administrator (right-click and select "Run as administrator").

After reinstalling, configure your custom fan presets and reboot your computer to see if the issue is resolved.

4. Check Boot Camp Drivers

Outdated or incompatible Boot Camp drivers can sometimes cause unexpected issues. Make sure you have the latest Boot Camp drivers installed for your Mac Pro 5,1. To update the drivers:

  1. Download the latest Boot Camp drivers from Apple's website for your specific Mac model.
  2. Follow the instructions provided by Apple to install the updated drivers.

After updating the drivers, reboot your computer and check if the problem persists.

5. Examine Event Logs

Windows Event Logs can provide valuable information about errors or warnings that might be related to the issue. Check the Event Logs for any entries related to Macs Fan Control or driver conflicts that occur around the time of reboot. To access the Event Logs:

  1. Type "Event Viewer" in the Windows search bar and select "Event Viewer".
  2. Navigate to "Windows Logs" -> "Application" and "Windows Logs" -> "System".
  3. Look for any error or warning messages that might be relevant.

The information in the Event Logs might help you identify the root cause of the problem and find a more specific solution.

6. Verify File Permissions

Ensure that the user account you're using has the necessary permissions to read and write to the directory where Macs Fan Control stores its configuration files. This is typically in the C:\ProgramData or C:\Users\YourUsername\AppData\Roaming directory. To check file permissions:

  1. Locate the directory where Macs Fan Control stores its configuration files.
  2. Right-click on the directory and select "Properties".
  3. Go to the "Security" tab.
  4. Make sure your user account has "Read & execute", "List folder contents", "Read", and "Write" permissions.
  5. If necessary, click "Edit" to change the permissions.

7. Contact Macs Fan Control Support

If none of the above steps resolve the issue, consider contacting the developers of Macs Fan Control for assistance. They may be aware of the problem and have a specific solution or workaround. Provide them with detailed information about your system configuration, the steps you've already taken, and any error messages you've encountered.

Additional Tips and Considerations

  • Check for Updates: Regularly check for updates to Macs Fan Control, as new versions may include bug fixes or compatibility improvements.
  • Monitor System Temperatures: Keep an eye on your system temperatures to ensure that your fan settings are effectively preventing overheating.
  • Consider Alternative Fan Control Software: If you're unable to resolve the issue with Macs Fan Control, you might want to explore alternative fan control software options.
