Speed controlling computer fans
For years I have been using the Silverstone fm121 as it comes with a remote mounted speed controlling potentiometer, goes as high as 110 CFM and 0.4 amps consumption. It is fairly quiet for this am...

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.
Lots if Ifs and perhapses in there.
One other consideration is Fan color. I've painted the White Silverstone fans black with appliance epoxy, so they are not easily noticed. A black sharpee works OK but takes forever to apply, adn when the fan blades need cleaning it requires some reapplication. I knew painting the impeller could throw out balance and wear the bearings faster, but seemed to have gotten the paint's weight distributed evenly enough.
The Black color of the Industrial Noctua's impeller and inside body, are highly desirable for me.
