Good day!

I just purchased the Asrock Steel Legend B450M board. So far everything is working fine, I'm just struggling syncing the RGB of my Antec Neptune 240 with the board. The Polychrome software does seem to pick it up but nothing I do in the software actually changes anything.

I have the radiator fans connected to the Antec controller for power and RGB, and I have the CPU block connected for RGB as well. I then have a cable coming out of the controller that goes to the CHA_FAN2/WP (Tried CPU_FAN2/WP but there was no reading) and ADDR_LED1 headers respectively. The connector only has 3 pins so I am unable to connect it to a 4-pin header.

Am I missing something or is this just one of those cases where things don't work? The Neptune 240 is advertised to be polychrome compatible so surely there must be a way to get it to work?

I'd appreciate any and all help!

Regards
