help with RGB connector

[Woahduds]

I have the asus x370 (here https://www.asus.com/us/Motherboards/ROG-STRIX-X370-F-GAMING ) which have two 4 pins rgb connector. My new case ( https://www.rosewill.com/product/atx-mid-tower-gaming-pc-computer-case-aura-sync-compatible-dual-ring-rgb-led-fans-top-mount-psu-hdd-ssd-tempered-glass-steel-prism-s500 ) it said it is compatible with aura sync but only have 3 pins connector. I wonder if there is a converter that i could buy to make it work?

3 pin should work in a 4 pin(PWM) (on the Mobo) but not the other way around as you lose the control pin (4th one)

not the fan rgb connector

so fan has 3 pin or 4 pin(PWM)

The RGB lights and fans you have are addressable RGB and will not work with 4 pin analog RGB headers which your board only has.

He's talking about the RGB lights on the fans and not the fan control itself.

my fan connector is not a 3 or a 4. It is a 4 pin connector but definitely not a fan connector. The fan connector connect to a hub and that hub connector needs to go to my motherboard rgb connector. The motherboard is 4 pin male but the connector of the hub is 3 pin female
