I was able to carry out a search and unfortunately was unable to find the fans individually or a model designation in any of the manufacturer's specifications. Unfortunately, the advanced search also failed. I assume that it is Basic fans that are supplied and that they offer other models for sale individually. The manufacturer may be able to send you some directly.
The RGB fans in this case are pre-chained, meaning they use daisy chain technology and only require a single cable connection to the motherboard. The fans can be clipped together easily and controlled via a single USB port or header on the motherboard, allowing management of multiple fans through one connection. This setup is typical for the Lian Li UNI FAN CL series fans compatible with this case, which feature integrated wireless receivers and daisy chain clips for simplified wiring.
