Hi @daltong00 ,
thank you for contacting ASUS support. We appreciate you reaching out to us regarding the issue with your ROG Ryujin II fan hub not having power.
We recommend you try the following steps:
- Reseat connections: Please unplug and replug the connections between the fan hub and the motherboard and power supply unit.
- Check other devices: Please temporarily unplug other ARGB devices connected to the motherboard to see if they are causing interference.
- Update the motherboard BIOS: Please visit the ASUS website to download and update the latest BIOS for your motherboard.
- Test with a different SATA power cable: Please try using another SATA power cable to see if the cable is faulty.
- Check the fan hub itself: If the above methods do not resolve the issue, we recommend that you try to replace the fan hub on another system to see if the fan hub itself is faulty.
- Check Device Manager and Armoury Crate: Please check Device Manager for any unknown USB devices and confirm that the ROG Ryujin is correctly recognized in Armoury Crate.
If the above methods do not resolve the issue, we recommend that you provide the following information via private messege:
- Motherboard model

The logs contain detailed information about the software's operation and can help the team identify the problem.
Please ensure that the logs accurately record the occurrence of the issue.
