  1. Hi there, thank you for sharing your impressive build! It looks like you’ve put together a well-balanced and aesthetically pleasing system. If you’re experiencing any temperature issues or fitting challenges, here are a few troubleshooting tips:

    • Ensure that the ID-COOLING FX360 AIO is properly installed with correct mounting pressure and thermal paste application to maximize cooling efficiency.
    • Double-check that the Thermalright AM5 Contact Frame V2 is securely attached and making good contact with the CPU surface to facilitate optimal heat transfer.
    • Verify proper airflow within the Lian Li A3 case by managing cables effectively and ensuring the intake and exhaust fans are working correctly—consider adding or repositioning fans if necessary.
    • If you’re facing ARGB synchronization issues, confirm that all ARGB headers are correctly connected to the motherboard and that you’ve installed the latest motherboard RGB control software.
    • For tight fits, consult the case’s manual for recommended cable routing paths and component clearance tips—sometimes small adjustments can make a significant difference.

    Feel free to share specific issues you’re encountering so I can assist further. Your build serves as an excellent example for SFF enthusiasts aiming for high performance in a compact design—keep up the great work!
