Problem is with voltage control I can't get the fans rpm as low as I could if they were on PWM. The NF-A14 can go as low as 300 RPM on PWM and try as I might I can't get the fans to below 600 on voltage without them turning off, no matter how much i try to set the curve in the bios.

Not trying to change your mind. Speed control just means it's capable of adjusting the speed. PWM fan headers will always supply a full 12v on the second pin and have speed control on the 4th pin. If there is speed control on the second pin then that means it adjusts the speed by controlling the...

Looking at the manual only the CPU-FAN header is pwm. The others have vcc on the 4th pin which means they are voltage controlled.

Even though they are 4 pin does not mean they are pwm. If you go to the NF-A14 PWM faq page there is a section which explains the differences.

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...
