The MSI Codex R2 desktop is known for its impressive performance and visual appeal, but sometimes the RGB lighting in the fans can develop issues, like flickering. Flickering lights can not only be annoying but may also hint at underlying issues with power delivery, connections, or software. This guide walks you through troubleshooting and resolving flickering fan lights, ensuring that your setup looks and runs as intended.
1. Check Physical Connections
The first step in diagnosing flickering lights is to ensure all hardware is properly connected. Loose or partially connected cables can easily cause flickering in RGB fans.
- Secure All Connections: Start by turning off and unplugging your PC. Carefully open up the case to inspect the internal connections, specifically looking at how the RGB fans connect to the motherboard or power supply. Look for any cables that might have loosened over time or might not be firmly seated. Firmly push any connectors into place if they appear loose.
- Reseat Connectors: It can be helpful to unplug each fan cable from its connection point and then plug it back in. Sometimes, this simple step can correct issues caused by incomplete or intermittent connections, which are often the culprit behind flickering lights.
2. Inspect the Power Supply (PSU)
The power supply unit (PSU) is crucial to providing consistent power to all components, including the fans and RGB lighting.
- Check PSU Wattage: If your system has multiple accessories (e.g., additional fans, graphics card, or RGB components), it could be close to reaching the PSU’s power output limit. When the PSU can’t deliver sufficient power, RGB lights may flicker as the system prioritizes more critical components. Confirm that your PSU’s wattage is sufficient for your setup by checking the power requirements of each component and totaling them up.
- Test with Another PSU (If Possible): If you have access to another PSU, try swapping it temporarily to see if the flickering stops. This test can reveal if your current PSU has trouble delivering steady power, potentially indicating a faulty unit or one that’s undersized for your system’s demands.
3. Adjust Software Settings for RGB Lighting
MSI desktops often come with proprietary software to control RGB settings. For the Codex R2, MSI’s Mystic Light software is designed to manage lighting configurations and patterns.
- Use MSI Mystic Light to Customize Settings: Open the Mystic Light software to access your RGB controls. Make sure that you aren’t unintentionally using a flicker or pulse effect, which can sometimes resemble a malfunction. Switch to a solid color or steady mode to see if the flickering persists.
- Update RGB Control Software: Outdated RGB software can cause unexpected issues. Download the latest version of MSI Mystic Light from MSI’s website to ensure you’re running the latest bug fixes and compatibility updates.
- Check for Third-Party RGB Software Conflicts: If you have other RGB control software installed (such as ASUS Aura, Gigabyte RGB Fusion, or Corsair iCUE), it can conflict with Mystic Light, causing lights to act unpredictably. Uninstall or disable any competing RGB software to prevent interference.

4. Check for BIOS or Firmware Updates
In some cases, BIOS or firmware updates can include fixes for RGB-related issues, especially for systems that rely on specific fan controllers.
- Update BIOS: Go to MSI’s official website and search for the latest BIOS updates for your Codex R2 motherboard model. Firmware updates sometimes address compatibility with new RGB hardware or fix minor bugs affecting lighting. Follow MSI’s instructions for BIOS updates closely, as improperly updating BIOS can cause stability issues.
- Update Firmware for RGB Controllers (If Available): Certain fan controllers or motherboards have firmware updates specifically for the RGB functionality. Check MSI’s support site for any updates related to your system’s RGB lighting components.
5. Test Each Fan Individually
If only one or a few fans are flickering, the issue may be isolated to specific components rather than the entire RGB system.
- Swap Fans Between Ports: Move the flickering fan to a different RGB header or fan port on the motherboard (or fan controller if one is used). If the problem follows the fan, the issue may lie within the fan itself.
- Test with a Different Fan: If possible, replace the flickering fan with another one that you know works correctly. This method can confirm if the issue is hardware-specific to a fan or a connector.
6. Inspect the Fan Controller (If Applicable)
Many pre-built systems like the MSI Codex R2 come with a fan hub or controller, which consolidates power and RGB signals for multiple fans. These controllers can sometimes develop issues if a connection is loose or if the controller itself is failing.
- Ensure the Controller is Properly Connected: Make sure that the controller is securely attached to the motherboard and that all cables are fully inserted.
- Reset the Controller (If Possible): Some controllers have reset buttons, or you may be able to reset the RGB by disconnecting and reconnecting the power.
7. Consider Electrical Interference
Sometimes, the issue may be due to the power supply from the outlet rather than your PC hardware.
- Use a Surge Protector or UPS: Make sure your system is plugged into a stable power source, ideally through a surge protector or an uninterruptible power supply (UPS). Electrical interference from the wall outlet or power fluctuations in your area can sometimes affect the performance of RGB lighting and other sensitive components.
- Avoid Overloaded Power Strips: Plugging your PC into an overloaded power strip can also cause inconsistent power, which may lead to flickering lights. Try plugging your system into a different outlet or power strip to see if that resolves the issue.

Troubleshooting Summary
- Physical Connections: Ensure all cables are securely connected and reseat any that might be loose.
- Power Supply: Verify your PSU’s power adequacy and consider testing with another PSU if possible.
- Software Settings: Use Mystic Light or other RGB control software to set a stable lighting mode and remove any potential conflicts.
- BIOS and Firmware: Check for updates to BIOS and any RGB controllers to eliminate compatibility issues.
- Fan Testing: Test fans individually by swapping their connectors or replacing them temporarily.
- Fan Controller: Confirm that the fan controller is connected properly and reset it if necessary.
- Power Stability: Use a surge protector or UPS and avoid overloaded power sources.
When to Seek Professional Help
If, after trying these troubleshooting steps, your MSI Codex R2’s fan lights still flicker, it may be time to seek professional assistance. Persistent flickering could indicate a more serious issue, like a motherboard defect, a PSU with voltage irregularities, or a malfunction in the RGB controller.
Final Thoughts
While flickering fan lights can be frustrating, the cause is often one of the more manageable issues mentioned above. By following these steps methodically, you can address potential software, connection, power, and hardware issues, restoring your MSI Codex R2’s lighting to its full, steady functionality. Remember, a stable system not only enhances visual appeal but also ensures a smoother computing experience.
