MSI Afterburner is the go-to software for any PC gamer looking to overclock their graphics card. One crucial aspect of tweaking your GPU’s performance is controlling its fan speed. However, a significant number of users have reported the fan speed control feature not working correctly on Windows. In this article, we’ll walk you through how to fix this issue.

Firstly, it’s essential to understand what causes the MSI Afterburner fan speed control not to work. The problem arises when the software loses read/write permissions for the Windows Registry. This registry holds critical information about your computer, including hardware configuration and software settings.

Without these permissions, the software cannot make the necessary adjustments to your GPU’s fan speed. Luckily, fixing this problem is relatively simple, and here’s how to do it.

Step 1: Close MSI Afterburner and any other third-party software affecting your GPU.

Step 2: Press Windows key + R to open the Run dialog box.

Step 3: Type regedit into the text field and hit Enter to open the Registry Editor.

Step 4: Navigate to the following directory: HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\‌‌Run.

Step 5: Right-click on MSI Afterburner and select Delete.

Step 6: Restart your computer and open MSI Afterburner as usual.

By deleting the MSI Afterburner entry in the Windows Registry, we’ve essentially reset the software’s permissions, allowing it to once again read/write essential settings.

If this method doesn’t solve the issue, you can try reinstalling the software entirely. Before doing so, we recommend using an uninstaller tool to remove all traces of MSI Afterburner from your computer. Once you’ve done this, you can download and install the latest version of the software from the official MSI website.

In conclusion, the MSI Afterburner fan speed control not working on Windows can be a frustrating issue, but it’s relatively easy to fix. By deleting the software’s entry in the Windows Registry or reinstalling it entirely, you can regain control over your GPU’s fan speed and enjoy a better gaming experience.
