High GPU fan speed on idle

RTX 2060 SUPER VENTUS OC fan doesn't go below 1000 RPM on idle (1% activity, 30°) when set to 0 in MSI Afterburner, which causes a loud noise and, I assume, a fan wear.
"Predefined fan speed curve" value set to Default makes it spin at ~1400 RPM on idle.

Your target the fans to turn off at idle? If so, set fans "Auto" then test again.

There's no "Auto" value in Afterburner Fan setting, only Default which is the same, I think.
And as I said it makes the fan spin at ~1400 RPM.
When I'm setting the fan speed to 0% via "Custom" option it lowers to 1000 RPM but not less.

That's normal, fan can't be set to off when custom fan curve is used.

There's no "Auto" value in Afterburner Fan setting, only Default which is the same, I think.
It not possible to do not have "Auto"

See here where is "Auto" FAN button

Oh, I haven't noticed the "Auto" button, thanks.
Result is the same when it's turned on, though.
The minimal value on a Fan Speed slidebar is 29% on my screenshot. Does it mean that it couldn't be set lower that this?

Found something called "Zero RPM" option by searching the internet. Only forums posts, not GPU specifications so I cannot be sure.
But it seems legit that VENTUS GPU does not have this option since it's the cheapest one.

Also the feedback on this feature is quite controversary.
From one side, it sounds good to let the fan rest sometimes, but from the other side, shutting the fan down and starting it over continuously may be worse than consistent spinning.
The speed of 1000 RPM still seems high for me.
