[SOLVED] Fan curve not working in BIOS at all ?

[irevidedxl]

Hey guys,

for some weird reason I am unable to edit the fan curves in BIOS. Nothing happens changes when I put it on manual mode or silent/balanced. Does anyone know how to fix it?
Also for some reason chassis 1 fan is always around 1200 rpm and I am unable to lower the rpm. BIOS image

Processor Intel(R) Core(TM) i7-8700 CPU
ROG STRIX Z390-E GAMING
RTX 2080 Gaming X Trio

Case: Corsair 680x
Fans: LL120 RGB 120mm


Edit 1: I forgot to mention that I also did a clean installation of Windows.

While in bios nothing is supposed to change, do you boot into windows after changing anything to see if it changed something?
Also some fans have a standard speed or don't go below a certain rpm, you will have to see the model number of fan1 and search on the web if it's normal or not.

Yes I boot into windows to check if it changed. I am just unable to change it.

I followed this video to see if I can change the fan speeds with this app and it also won't let me. I can't even turn the fan off...

I seriously don't know what's wrong with my fans.

Are you using the Corsair utility called iCUE? If yes, note that it takes over control of your fan motors AND lights. So any settings you make in BIOS Setup will be changed to whatever iCUE is set to do. Use iCUE for your settings IF you have it installed.

Slightly silly question - Have you tried clicking on the "QFan control" button?

I don't use any software to control my fans. I did a clean windows installation as well but nothing helps...

It's not a silly question, and yes I have tried it.

Ok, then tell us how and where all your fans are connected to motherboard.

This is my first PC and I built it with my friend so I'm not that experienced.

3 front fans are connected to the chassis header at the bottom right.

At the top the CPU OPT and CPU FAN are connected.

On the left the chassis fan 1 is connected but the AIO pump is not. Maybe It should be connected to the AIO instead? Although it isn't the CPU cooler fans that aren't working.

So no hub or anything like that? All fans directly connected to motherboard, correct? Three LL 120 on the front connected to CHA_FAN 2, W_PUMP and M2_FAN and one (unknown) on the rear connected to CHA_FAN 1 header, plus CPU fans on their own headers.

Now, there is no speed control on W_PUMP header so the fan connected there will always run full speed. The rear fan - I suppose it could be 3 pin fan, and if the header is set to PWM control then you will not be able to control its speed either. However, the remaining 2 front fans should be controllable on QFan screen in that setup.

It is connected to an RGB hub but I have no idea how any of that works. There's a fourth fan at the back connected to the top left of the motherboard

It is connected to an RGB hub

As long as only RGB cables are connected to hub it does not matter.
