Can't control case fans in bios/software

The fan speed controller to your front panel seems like it has to overwrite the BIOS settings. If you don't plug in "F" on the fan hub, do things start working better?

You could also try going to your BIOS and setting fan header D to DC mode instead of PWM. See if you can control it that way. The hub might not be reporting speeds back to the motherboard correctly.

This is the hub for my case (dark base pro 900.)

I have A connected to a pwm fan header on the motherboard and a rear exhaust fan plugged into the first slot on the left but it doesn't get picked up for some reason in the bios or in monitoring software. The same happened when I had 3 case fans connected to the top 3 slots.

 

A from above goes to D here. I don't think I did anything wrong, is there anything that I could have messed up? Technically I can still control case fans through a front panel slider to an extent, but a custom fan curve would be ideal.

I'm not actually trying to be as grumpy as it seems.

I will find your mentions of Ikea or Gnome and I will /s post.

Was able to modify case fan speed in bios just now, but it's a bit finicky, sometimes the rear fan doesn't follow the speeds I set, just gonna wing it and hope that it actually ramps up when the pc heats up too much, if not I'll find out one way or the other.

 

Only downside with the radiator fans connected into the hub now is that with the front panel slider if I take them off manual mode(bios control) the radiator fans turn up really hard cuz they are higher capacity than the single rear fan, but if I just stick to custom bios fan curves it's not an issue. 

 

Anyways, thanks for the ideas
