Gigabyte GeForce RTX™ 4080 16GB AERO OC Fan speed issue

[NazZaR]

Hello!
I have some weird issue (or not) with my Gigabyte GeForce RTX™ 4080 16GB AERO OC.
Usually for RTX cards in idle, fan stop is at around 30% speed. But with this Gigabyte 4080, it is around 52% for some reason. And it does some weird stop-speed up constantly if set below 52%. It comes to almost full stop and then speeds up rapidly to over 1500RPM and then calms down. And this cycle continues unless you set it to minimum 52% speed, which is a lot for GPU without load.
I don't know, whether it is by design or I am doing something wrong.

Here is a video of GPU behavior when set under 52% speed.

Turns out it is probably some of strange Gigabyte decisions. This fan speed behavior is by design.

What kind of start/ stop % did you set on the control card for the GPU?

From your reddit thread it seems like there is some built in behaviour you got to play around with as you mentioned.

I left the values that Fan Control detected:
