Can I control the fan speed via software? (over usb)

Mind is controlled but done with firmware. It is super quiet thou

What resistors do i need to work with my raspberry pi 4 pwm

Depends on how your attaching it, I'm using it via the enclosed usb adapter for past 6 months, but it runs constant, I have purchased a 2n2222 npn transistor but not used it yet in conjunction with pinouts for temperature control.
