Once again for understanding: You want to connect a single UNI FAN SL-INF wireless fan (Art. 59300087) to the analogue controller of the old UNI FAN SL-INF (without wireless, Art. 21233127) - i.e. wire it in the classic way and use it to control speed and RGB, correct?
If that is your plan, the answer is unfortunately: No. To operate the new SL-INF Wireless, the Wireless Sync Controller (Art. 53791303) is absolutely necessary.
If you want to use both fan types in the same system, you will need two separate controllers: - the old one (from the SL-INF three-pack) for the wired SL-INF - the new Wireless Sync Controller for the SL-INF Wireless
Attention: Many mainboards only have 1-2 internal USB headers - you may need an internal USB splitter, e.g. from Lian Li itself (Art. 24915941).
And if you still have a little patience - I will soon be selling off my entire Lian Li mess. The controller ghetto is absurd: between SL-INF, TL, Wireless, Strimer and co. I sometimes had three controllers in use at the same time. Hardly compatible with each other - and don't even get me started on L-Connect 3. 🤬
Ok good to know but is it the same if you connect the fans via the 3pin argb and the other one as with the controller or do you have more setting options via L-Connect 3?
