Why Corsair Fans Not Showing Up in iCUE?

Corsair fans may not show up in iCUE due to various reasons, and troubleshooting the issue requires a systematic approach. Here are some common factors that could lead to Corsair fans not being detected or showing up in iCUE:

  • Software Glitches: iCUE is a complex software, and glitches can occur during updates or changes in the graphical user interface. Running the wizard setup again on iCUE or reinstalling the software might resolve these issues.
  • Firmware Issues: Fans may not be detected if there are problems with the firmware. Forcing a firmware update for the device the fan is connected to could potentially resolve the detection problem.
  • Loose Connections: Physical issues, such as loose cable connections, can result in fans not being recognized. Checking and securing all cable connections, and then forcing a firmware upgrade, might help bring the fans back into view.
  • Hardware Configuration: Incorrect hardware configurations, such as connecting 3-pin fans to a port expecting 4-pin PWM fans, can lead to detection issues. Verifying the hardware setup and adjusting settings accordingly in the iCUE device settings may solve the problem.
  • Power Supply Concerns: Inadequate power supply or issues with the SATA power connector might affect the functioning of fans. Changing the SATA power connector to a different cable on the PSU could potentially resolve power-related problems.
  • Controller Limitations: Corsair controllers, like the Commander Pro, have limits on the total current they can handle. If the connected fans exceed this limit, it might result in detection issues. Reviewing the current usage and considering using a separate controller if needed can be a solution.
  • Interference from Other Software: Other software applications, like hwinfo64, might interfere with iCUE’s detection process. Ensuring that conflicting software is properly configured or temporarily disabling it can help diagnose the issue.
  • RGB Current Limitations: Exceeding the maximum allowable current for RGB components, especially if numerous RGB devices are connected, can lead to detection problems. Adjusting the RGB settings and considering alternative configurations may be necessary.
  • Corrupted Software Installation: A corrupted iCUE installation can cause various issues, including fan detection problems. Reinstalling iCUE and forcing firmware updates after the reinstallation might eliminate any underlying software corruption.

How to Fix iCUE Not Detecting Fans or Not Showing Up Fans?

Follow the below methods to resolve any error while running the iCUE utility.

1. Restart, Reinstall, and Update iCUE

If you encounter the issue of Corsair iCUE not detecting fans, start with these three essential steps for a potential resolution.

  • Restart iCUE: Close the Corsair Utility Engine and open the Task Manager by pressing Alt+Ctrl+Delete on Windows 11/10. Locate the iCUE process, right-click, and choose “End Task.” Ensure that the application is completely closed from the system tray. Relaunch iCUE to check if the detection problem is resolved.
  • Reinstall iCUE: If restarting doesn’t solve the issue, consider a full uninstall of iCUE, making sure to remove all files and profiles associated with the program. After uninstallation, reboot your system and reinstall iCUE. In many cases, this step alone resolves the fan detection problem.
  • Update iCUE: Keep your iCUE software up-to-date by visiting the Corsair iCUE download page and downloading the latest version. Install the updated version on your computer. Corsair frequently releases updates to address errors and enhance functionality, so ensuring you have the latest version may resolve the fan detection issue in iCUE.

2. Uninstall Conflicting Software

If you find yourself unable to monitor fan speed or voltage through iCUE, it’s likely that conflicting software is attempting to access the same information. Running multiple PC monitoring programs on a Windows PC can lead to data gathering conflicts and deactivate the Corsair iCUE cooler interface.

Various programs, including HWiNFO64, HWMonitor, EVGA PrecisionXOC, MSI Mystic Light, Riva Tuner, and Asus AuraRGB, are known to cause conflicts with Corsair cooler drivers, preventing efficient RGB control and fan detection in iCUE.

To address this issue, uninstall all other monitoring programs that may be running on your system to avoid conflicts. After uninstallation, reboot your PC and manually reactivate the Corsair iCUE driver:

  1. Open iCUE.
  2. Navigate to SETTINGS.
  3. Select “Restart iCUE Service.”

3. Rearrange the Fans on the Controller Hub

If you’re grappling with Corsair iCUE not detecting fans or RGB components, particularly when using a CommanderPro fan controller, rearranging the fans on the hub might resolve the issue.

Follow these steps:

  1. Check Fan Controller Configuration: Ensure that the lighting channels on the fan controller (CommanderPro) are configured correctly.
  2. Manually Add Fans in iCUE: When fans are connected to the fan hub, they might not be automatically detected by iCUE. Manually add these fans to iCUE in an organized manner.
  3. Rearrange Fans on the Hub: Fans on the hub should be arranged properly. If the RGB fans are not operating as expected, try rearranging them on the hub controller.
  4. Sequential Operation: RGB fans operate in a sequence; if the first fan in the hub doesn’t receive a signal, it won’t pass it to the others. Ensure a proper arrangement to prevent one malfunctioning fan from affecting the entire chain.

By rearranging the fans and ensuring correct configurations, you enhance the chances of iCUE detecting and controlling both fans and RGB components effectively.

4. Specify Fan as 4-Pin PWM in the iCUE

If Corsair iCUE is only recognizing a subset of your fans and seems to miss others, especially when controlling fan speed through a fan controller like CommanderPro, adjusting the fan specifications can help.

Follow these steps:

  1. Access iCUE Settings: Open iCUE and navigate to the settings.
  2. Specify Fans as 4-pin PWM: Within the iCUE settings, locate the fan configuration options. Change the fan specification from “Auto” to “4-pin/PWM.”
  3. Check Fan Hub Headers: Additionally, confirm the fan headers on the fan hub. Ensure they align with the specified fan type (4-pin PWM).

By explicitly specifying the fans as 4-pin PWM in iCUE settings and aligning the configurations with the fan hub headers, you can address the issue of iCUE not detecting all fans. If the problem persists, there’s one more potential fix to explore.

5. Run Wizard Setup Again

Running the wizard setup again on iCUE can help reconfigure settings and potentially resolve any software glitches that might be affecting fan detection.

6. Force Firmware Update

Forcing a firmware update for the device the fan is connected to can be an effective solution, especially if there are issues with the current firmware.

7. Check for Loose Connections

Ensure that all cable connections, especially the ones connecting the fans, are secure. If a fan is not showing up after a loose cable connection, forcing a firmware upgrade might bring it back.

8. Verify Hardware Configuration

Check and confirm that the hardware configuration aligns with the settings in iCUE. Ensure that 3-pin and 4-pin fans are correctly identified in the iCUE device settings.

9. Adjust Power Supply Connections

If there are power-related issues, changing the SATA power connector to a different cable on the PSU might help in resolving problems with fan detection.

10. Consider Controller Limitations

Corsair controllers, like the Commander Pro, have current limitations. Check the total current usage and consider using a separate controller if the current exceeds the specified limit.

11. Manage RGB Current Limitations

Be mindful of RGB current limitations. Exceeding the maximum allowable current for RGB components, especially with multiple devices connected, can lead to detection problems. Adjust RGB settings accordingly.

12. Seek Manufacturer Support

If all else fails, reaching out to Corsair’s technical support is advised. Their team can provide personalized assistance and guidance to address specific issues.

Remember to follow these solutions systematically and, if needed, seek additional support from Corsair’s technical team for a more tailored resolution to the Corsair iCUE fan detection problem.
