Hey so i wanted to change my case fan control on my bios. I have a z390 aorus ultra motherboard so I went to smart fan 5 in my bios. I tested by trying to turn the fan to the lowest using the curve but nothing happened. I need some help thanks.

Are they PWM fans?

Are they plugged into a PWM compatible header?

Did you set them up in bios as PWM?

Yes

If you set them to the lowest rpm when they already are quiet then it won't make a different try setting them to 100% and see if they get louder and ramp up. If they are detected and set up correctly then they should work with Smart Fan 5.

What fan are you using and which header did you plug it into? What rpm is the fan running at?

about 1000 rpm for all 4 and theyre in system fan header and theyr epwm

The headers are labelled. What are the fan model names and which one are they each plugged into?

Are they plugged into individual headers on the motherboard?

Did you use the Calibrate function in Smart Fan 5?

No whats that.

There's a button that says Calibrate. I think it registers the fan rpm range and fan control might not work properly or at all without using it.

Have you tried pressing F7 to go to Advanced Mode? It might show up in a different Smart Fan 5 menu.

The option should be available when you first enter the motherboard settings.

The fans going to max rpm probably means that fan control works. I think that only makes the fan follow the temps for the pcie slot itself and not the gpu. You can try it and find out.

Ok thanks. Is there a program I can use that lets me control my fan speeds? I tried speedfan but my fans were not showing up.

If you can't do it from the bios, you can try downloading Gigabyte's SIV / Smart Fan 5 program and try controlling it from within Windows instead.
