How many fan controllers do I need?
If you are looking to control Performance Fans using NZXT CAM, the fans must be connected via an NZXT controller such as the Control Hub. For most configurations, only a single controller is necessary. Some example configurations are included below:
Control Hub + Kraken Elite/Kraken Plus 360 (2024)
This configuration will require minimal wiring or additional accessories, however it will be limited to 120 mm base fans (F120X and F360X) and radiators (Kraken Elite 360).
