It is not possible to mount the radiator of the "Liquid Freezer III 420 A-RGB" from Arctic directly onto a fan from Lian Li, as the radiator and the fans of the Liquid Freezer III are designed as an integrated unit. The fans are pre-installed and their cables are hidden in the hose sheathing, making installation with the cooler's own system simple and straightforward.

If you want to use a Lian Li fan, it would need to be specifically compatible with the Liquid Freezer III's radiator, but this is not the case as the configuration and connections are specifically designed for the Arctic system.
