Using industrial fans for gpu deshroud mod. (alien.top)

Per the title, I have installed some high cfm and high wattage fans on my 4080, it works fine but i'm currently using a manual knob to control the dc. Because I bought them without even a fan header, they just have 2pin connectors - does anyone know of any controller hubs I can use to both power them (.7a/8.4w per fan), and control the dc via a mobo header?

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
