Adrenaline driver create curve If I set it in below 20% speed | AMD RX 5600 XT

[sapphired18]

Fan Control: v199
GPU: RX 5600XT
Driver Version: 24.8.1

My GPU, does not have 0 rpm if I use advanced control in AMD Adrenaline

Here's the image in adrenaline if I set 20% as lowest point in Fan Control

Can Fan Control adjust to "Zero RPM Mode" if I set certain range like below 20%?

The image below is what to my mind, it should behave

if it under 20% in Fan Control it will create a curve in AMD Adrenaline

This is what actually happen

Here's the calibration result

If your GPU doesn't support it natively, no.

if it under 20% in Fan Control it will create a curve in AMD Adrenaline

That's the GPU defaulting back to a stock curve because the command sent was not valid/out of range. Keep above 20%.
