is it posible to create a custom fan curve in my motherboard bios?

[LukeTheLama]

basically, I've been trying to create a fan curve that isn't the silent mode in smart fan as the silent mode still ramps ramps up fast from 40c which is my idle lol. Anyway, I've been trying to customise it but it won't let me at the points just aren't moving. My fans are 3 pins so I have to control them in the bios as they don't have PWM which is annoying. I've got an Aorus b550 elite matx mobo. I can't use software to control the curve due to it being 3 pin.

You may have to set the BIOS setting to [Voltage] from [Auto] control as Voltage based fan curves are for 3-pin fans and varies the voltage applied to the fan.
