DTov77 Posted January 11, 2021 Share Posted January 11, 2021 My first build. Connected 3 Corsair LL120 Fans directly to a ROG STRIX B550-F motherboard and they aren't working at all (no power or lights). Do I need a hub to connect them? Any other suggestions / guidance on how to fix? Link to comment Share on other sites More sharing options...
c-attack Posted January 11, 2021 Share Posted January 11, 2021 Don't do that. If the connector doesn't fit exactly, there is a reason for it. Corsair RGB fans require a controller and separate power source. They were not designed to be powered from your MB RGB headers. If you connected to a 5v D-RGB header, they might still be OK. If you connected to the 4 pin 12v RGB header, the fans may be damaged.
