Nope. Too much power for consumer fan controllers. Most of them barely use 2W per fan.
Well, you can get an Arduino and code your own hub, you're already able to control it with a knob, so just automate it with a microcontroller.

And a mosfet between Arduino and the fan. Arduino generally tops out at 20mA per pin which is 0.1w. A decent mosfet can handle several amps and can even drive 12v fan from a 5v pin.
/r/AskElectronics should be a good place to ask for the right kind of mosfet that is able to handle 1A or more (want to have some margin), can be driven by 5v at gate pin and can handle 12v at source and drain pin.
Most motherboard fan headers support 1 amp, while high end ones have 3 amp ones available for things like water pumps. I would just buy adapters to terminate your fans and plug them directly into the motherboard, using one header for each fan as to not overload it. You will be able to control the fan in your bios/software with voltage instead of pwm but it will work basically the same.
This is what I was looking into, but I can't find out what my motherboard's headers r rated for
The motherboard controls the fans with a PWM signal. Other posters are right that your motherboard can't power your fans directly, but if you can find a suitable MOSFET module (or solder up your own) you can use the signal from the motherboard without pulling too much current and damaging it.
