Compatibility between the ASUS ROG Crosshair VIII Hero WI-FI motherboard and the Corsair iCUE H100i Elite Capellix XT water cooling system is not directly dependent on motherboard compatibility, as water cooling systems are typically connected via USB or SATA and are not specifically based on motherboard models. However, the iCUE software can work with ASUS motherboards to control RGB lighting, although there may occasionally be conflicts with other software tools.

To ensure that the iCUE software works correctly, you may want to disable other monitoring or control software.
