    p870tm motherboard was actually designed with the 2nd CPU fan in mind, so was the CPU HS!

    wandering if it's 12v or 5vm...

    @Prema? @Papusan? @Mr. Fox?

    yea john posted the pin out info from b4. btw is that how 12v works? if so we'd need to find a 5mm 12v fan first and make sure the wiring is similar otherwise worst case would just be 5v. waiting for the fan to arrive.

    They never actually shipped KBL-R dev-units with that FAN, so I don't know what exact FAN model they intend to use for CFL...but I am sure if you are searching taobao long enough you'll find it.

    4-pin fan, with integrated power driver. Needs only low-power PWM signal on control pin to RPM controll, or, if left this pin floating, fan will be working on full speed.
    First, we need to check if this output is enabled in EC. If yes, voltage on pin 2 should change toghether with speed change of main fan.

    honestly though i wouldnt mind have a fan running on 5v at full speed, noise and temp reduction result will dedicate the final decision, though having more choices to do fan control is better.
