    PWM issues

    Hey all,
    I'm trying to wrap my head around as to what I'm doing wrong here.
    I've upgraded my 4 PWM Corsair fans recently to the Corsair LL series.
    They're connected to the node pro hub for the led/light effects and from there their 4 pwm pins go to the same splitter that ends up in the CPU_FAN of my VII Maximus Ranger mobo.

    Everything works as it should, lights effects etc but I have absolutely no control.
    AI Suite 3 shows a PWM max fan speed of 750-800RPM.

    Help?

    I can’t understand where you connected the 4 fans PWM cables... what is “the same splitter”?
    Anyway, if you are planning to control your fans speed via BIOS (or AI Suite), try to connect them to mobo headers, directly if you have 4 available, or via Y splitters.
