It seems BIOS using RPM values instead of PWM percentages. I've lowered PWM percentage to 1, 3, 5% and fan runs on about 1400 RPM. Is there a way to adjust PWM and RPM values?

I don't have another fan to connect and it seems fan connected properly. PWM percentage tied to RPM. But RPM values are 10x higher. Check screenshots I've made. 100% PWM equals to 15k RPM.PWM and RPM are tied to one control, since PWM dictates the percentage, as you are aware, and the RPM by the fan itself.
There's a lower limit to how slow a fan model can spin. Bigger fans can run as low as 300 RPM, a typical 120mm would probably run at 700-1000 RPM depending on model. At lower PWM percentage the fan would just spin at its minimum speed. Voltage (3-pin) controlled fans would simply stop spinning beyond its lower threshold.
Out of curiosity, is the fan fully plugged in? I had a similar issue with my GPU AIO that turns out my 4-pin connector to GPU power isn't plugged in all the way. The fans spin at 100% speed (since it's receiving 12v) due to no or bad PWM signal.
You can also try plugging in another fan to the header through a splitter or hub to see if the issue persists. Could be bad PWM chip inside Thermalright fan, unlikely, but can't hurt for deductive reasoning.
Ah alright, is that the MSI software? Could be its interfering with BIOS settings. I'm not familiar with motherboard manufacturers' desktop software, but the general gist is that they're finicky to work with and not as reliable as BIOS settings. Try uninstalling that and monitor temps/fan speed with HwInfo.I don't have another fan to connect and it seems fan connected properly. PWM percentage tied to RPM. But RPM values are 10x higher.

It's BIOS HW Monitor. I'm not using any 3rd party software.Ah alright, is that the MSI software? Could be its interfering with BIOS settings.

try reinstalling the Gigabyte GPU control software.It's GPU fans which are causing the trouble.
may just be a design flaw in the card.Fans are still loud even at 25%
how do you think you may have damaged the fan's sensors?Is it possible that I damaged RPM sensors on fans? Should I replace them?
