Hello yes, in the fifth picture of the description, you can see the 4-pin RGB 12V cable perfectly, I connected it without any problem and it works perfectly.

These fans need a Thermaltake RGB controller to be able to use their full functionality and to synchronize them. Thermaltake Sync Controller TT Premium Edition (SATA, 9x)

Hello The more expensive edition comes with a controller to control the ventilation. These can also be turned down to 500 RPM. The "cheaper" ones only go down to 800 RPM. Kind regards

Hi, yes exactly. You can use these fans with Aura Sync, daisy chaining also works (so you can plug in several fan light control cables in a row and then route them into the Aura Sync port).

Ja, das MSI B450 Tomahawk (AM4, AMD B450, ATX) hat 6 Fan-Headers.
