    3090 Strix OC fans not spinning under load/manually

    I noticed that 1 fan was not spinning (rear fan) under any load condition or when I toggled manual fan control and then set them to 100% in MSI Afterburner. That was a few weeks ago. Now the rear fan is spinning but the other two are not. Same issue as with the rear fan ; Under load only that fan spins and setting to 100% fan speed in MSI Afteburner does nothing.

    I have updated everything that Armory Crate had just to be sure it a fix wasn't released there.

    Please advise if there is another piece of software that will work. I can't imagine this is normal behavior.

    Thanks.

    System Specs if needed.

    3090 Strix OC

    Hello,

    Try GPU Tweak 2 or participate in the GPU Tweak 3 beta via Discord.

    Disable ALL "Tweaksoftware" like MSI-AB or GPU-Tweak ...

    Put load on the GPU...
    All fans start/stop spinning together => ok
    Only one fan start/stop => most like this is a hardware-problem...

    When you turn your computer on, are all 3 fans spinning?

    yup, get rid of all the 3rd party crap that you are running in the background and just run the ASUS native software.

    When I use any software to manually control the fans they do not spin. In GPUz it shows fan percentage at 100% but RPM is 0. The same is true when I uninstall all software that lets me control the fans. Based on this I am thinking i need to RMA it.

    On a boot up the front and middle fan do not move at all. The rear fan spins though.

    When the fans do not spin at boot (without windows runing), the card is damaged and you have to rma it
