I've discovered that my motherboard has pwm fan control on the cpu fan header only. The other fan headers control them via voltage. As such my case fans have higher minimum speeds. I would like to know if there is a controller that provides true pwm control over fans or failing that the best way...

Ok, I'll just list things out instead of getting all wordy-smurdy :) because we engineers typically like stuff like that. 1. I have a cooling pad for a laptop. 2. Both 2-pin 5v Fans (70x70x15 mm) were failing. 3. The only 2 pin 5v fans I could find at that size are too loud. 4. Only quality...
