I guess another option would be the NON PWM 3 pin Noctua 140Mm fan. This Non PWM version only comes in 2000 rpm, not 3000, but would move about the same airflow as the 3000 rpm 120Mm version at highest speed.
Without the PWM on the fan's circuit board, perhaps it would not be cumulatively damaged by feeding the red and black with a pwm motor speed controller and perhaps not whine and perhaps meet or exceed my specifications for full speed range, and high airflow on high, and a very quiet lowest rpm for at night.
Best guess, a two or three wire fan should have no problem being used with speed controller.
