OK, so I noticed my fan wasn't turning on my 2080Ti, and that the block and radiator were getting REALLY hot. So, as a first test, I simply unplugged the fan from the 2080 and plugged it directly into another power supply, and, viola, the fan works just fine. Interestingly, I then tried plugging in the power that is sent directly from the 2080 in to another case fan, and, boom, it also works.
 
BUT, when I replug the eVGA fan back into it's own power on the 2080, it doesn't run, and it never comes on.
 
So, for now, I'm keeping the swap on so that both fans run continuously, until I hear from some of you folks about what could be happening here...j
 
thanks.

    New Build or GPU upgrade ?
     
    If upgrade what was your old GPU ?


    2080TI .. make Sure you use two separate PCIe power cables from your PSU 
     
    Run EVGA Precision X1 (always use the Newest Version - first) this can update your GPU "MCU" when it installs
     
    X1 - Will make several updates to other areas of the OS - when it installs  --> Install from an Admin logon & let it update those files
     
     
      turn Windows 10 Fast Startup OFF, when upgrading drivers, firmware or hardware


    With Windows 10 there is a new “hybrid” startup mode that should cut down on boot up times. 
     
    It does this by putting the PC into hibernation instead of "fully shutting down."

    Use Afterburner or X1 to manually control the fans.

    The fan on the rad should run at all times, and the fan on the card itself can shutoff and not run when below 60c.

    ok so this is a brand new build. 
     
    I just installed X1 today ( i know i know), but i'll turn fast boot off and see how that goes.
     
    And, yes, I have both power plugs installed and connected properly to the power supply.

    Just as a side note, here is how I have my XC with Hybrid kit setup for quiet cool running:
     
    Mods: Noctua A12x25 rad fans push pull on intake air, on MB fan header.  Mini-gpu adapter cable to plug pump into MB header.
     
    Settings: Fan/Pump control reading MB system temp sensor, in MB bios.  Below 35C, fans 1000 rpm, pump 7.5V (any lower and it won't start at boot).  35C and above, fans 1800 rpm, pump 10.5V.  Have several presets in Afterburner, light use is like 35% vrm fan and -100 mhz underclock, high OC is 130% power, +1000 mem, +135 clock, 70% vrm fan.  On high OC with 80-99% gpu use its around 50-55C.  I really like how it stays at a stable fan speed and never jumps around.

    thanks.




    Is the fan you're using on the radiator currently a PWM (4-wire) or a voltage control (3-wire) fan?  If it is PWM, the card is sending PWM signal.  If it's 3-wire, the fan is getting full 12V and running full speed, if the PWM signal wasn't being sent it wouldn't make a difference - you should try a PWM fan and see if it runs or not.
     
    Is the Rad fan reporting an RPM?
     
    Could be a bad connection?  Try bending the pins just a bit.
