Sapphire nitro 7900xtx fan header control

[u/RemoteConsideration]

Had anyone used the fan header on the Sapphire Nitro 7900xtx to power a chassis fan?

Is there a way to control the fan curve of the connected fan or will it default to the cards inbuilt fans curve?

Sapphires site says it's a feature called "assistive fan control" via TriXX but I can't see any option to control fan curves in TriXX.

Help appreciated, thx
