Check your motherboard manual to see if you can select type of fan control, and if you can can, change it from PWM to variable voltage.

You cannot control fans with other software if your motherboard does not have 3-pin variable speed fan control.
If your motherboard does not support 3-pin variable voltage control you will need to use an independent fan controller. Tealc (member here) used to make some very nice PWM to variable voltage controllers. Link below is to his thread about them. Don't know if he's still about, or if he is setup to still be able to make you one, but might be worth sending him a trust message and finding out.

Another option might be aqua computer Splitty9 for £9.95. They say "Splitty9 is a universal ninefold splitter and can be used for 3-pin fans".

are we talking about cpu header? do you have cpu_opt or smth like that? if you have two and one is DC and the other PWM it might create an issue

edit: btw you can take a bios screenshot with F12 you just have to plug in an NTFS usb drive

Assuming this is your sig rig, manual says sys fan headers 1, 2 & 3 are variable voltage controlled fan headers. Pin-2 on these fan headers is variable voltage.

Just because a PWM fan is changing speeds does not mean fan header is PWM. PWM fans plugged into variable control fan header change speed because of variable voltage from pin-2. On PWM controlled header pin-2 is constant 12v being pulse controlled by PWM control from pin-4.

Unbelievably I am still around. I haven't made one of those for years.

I would have thought most motherboards would support DC control by now. It's too limiting to have to use PWM in my opinion. If I didn't have a PWM board I'd never have gone about making the things in the first place.

Do Phanteks still make their little box?

Good to see you are still with us!
Indee, Phanteks still list their hub on website, but yours work better.
