NZXT Noctis 450 pwm controller issue.

[millerjeremy1991]

Hey guys, this is my first post so go easy on me 😉

Now I just picked up a shiny new Noctis 450 case with the PWM fan controller, plugged the 2 fans from my rad into the controller as well as the 4 preinstalled fans, and plugged the "PWM" wire into my "cpu_opt" header. Booted into windows and opened gigabyte's system information viewer(SIV) to calibrate my fan curve. It is reading my cpu fan (which is obviously my pump) but every other value is 0 but it seems like they are running at full speed all the time.

No matter what I do I cannot adjust the fan speed, I've tried speedfan and going into bios to see if I had a pwm/manual mode but no luck.

Before upgrading my case I just had a cheepo deepcool tesseract and with my radfans hooked up to a splitter(cpu_opt), exhaust fan(sys_fan1) and 2 intakes (sys_fan2, sys_fan3) everything ran fine using "SIV" or just letting the motherboard work its magic with PWM.

I'm at a complete loss right now, Any help would be greatly appreciated

Hi, I'd try connecting the 2 rad fans to CPU_OPT (as described in the cooler manual) and the controller PWM cable to one of the SYS_FAN headers.

The fan controller comes with a extension cable right? Where did you plug that in? Just to double check, the cable labelled 'extension' is it connected to the white socket on the fan controller?

I'm having the same problem. My controller is plugged into sys 2 pwm header and I plugged one of my pwm radiator fans into the pwm extension (white header on controller), I can control the fan speed of the radiator fan but the rest of the fans seem to stay on 100 %
