So ive had this fan controller hooked up to 9 noctua industrial ppc fans since last September and i love it ascetically however i cant have the rpm below 1080 or the fans will just go off next time i turn on my pc or go off if i bring it below 800 while the pc is on, this issue has always been there but the noise of the fans from 1090 - 1200 rpm hasnt bothered me too much however with the new 750d front panel with ventilation holes the noise is a little higher and unnecessary if the case will be the same temperature with the fans at 1200 or 800 rpm which is what id like them to be at, nice and silent.

Is there a solution to this problem ? like an adapter i can attach to them to reduce the voltage ?

if i had been smart at the beginning i would have just connected them all to the psu with a and a cable connected to the mobo to control them, but id like to still use the fan controller if possible for the internal temperature sensors.
 
Sorry i forgot to mention which fans im using, the following
7 x Noctua NF-F12 IndustrialPPC 2000RPM IP67 PWM 120mm
3 x Noctua NF-F12 IndustrialPPC 2000RPM IP67 PWM 140mm
 
I'd offer to swap, but I have 9 non-PWM Noctuas running off the very same controller!

Do you have the same problem taskmaster ? I thought it was faulty at first but it took so much effort to wire it all in I've just left it be, but I'd much prefer if it were silent considering Ip the temperature difference from 800 rpm and 1140 rpm will be negligible
