the default fan curve on the 3090 FTW3 Ultra V2 is useless;
- just sitting idle in the desktop and looking at HWiNFO64, the card will reach about 60ºC on the core, about 68ºC on the memories and about 70ºC on the hotspot before the fans start to spin, which will rapidly cool down the card and the cycle repeats...
- temps while gaming are absolutely horrible when using the stock fan curve...
 
and the third fan is rarely spinning at a constant rate like the other two fans, the third fan wobbles due to the constant variation in speed and the fan makes a "ticking noise" that sounds like plastic hitting plastic, probably the shroud.

and as we all know, the third fan (and fan header) on EVGA cards can only be controlled by Precision X1 which is absolute horse in its current state due to randomly unticking the "Fan Curve Control" on its own!
can you please fix PX1?
all I want is to stop having to babysit PX1 on every reboot just to make sure that the stock fan curve doesn't cook my card

    My first concern when reading this is your third fan wobbling and causing a ticking noise. Contact EVGA tech support for this problem. 
     
    Each person who has a PC case can have a varied amount of air being circulated within the case. The default fan curve is made for the majority of customers but perhaps it doesn't work for you so you'll need to make your own fan curve. Or alternatively instead of using PX1 try MSI Afterburner and you can also make a manual fan curve there.

    here's a 10 second sample of the ticking noise recorded on a HyperX SoloCast at 24-bit 48kHz set to 100%/+4.5dB volume in Windows, case side panel closed, all case fans and AIO fans running at the lowest possible RPM.

     my custom fan curve is linked to all 3 fans as seen in this screenshot

     
    but the third fan is always spinning at 21%~22% when the other 2 fans are at a constant 14%.

    sorry to see your having issues with PX1


    The default fan curve is for those who value silence most, so the fans only start once the card has gotten very warm
     
    Please test with GPU-Z & check the sensor tab for fan speeds, this lets us eliminate any software sensor errors associated with HWinfo utility
     
    1) what is your OS?
    2) which version of PX1 are you using?
    3) Nvidia driver?
     
     
    Couple of ideas for you (& how I use PX1 1.3.6)
     
    First, change the default bios on your GPU - there is a very small switch on the GPU near where the 3 power cables connect to the card.  Shutdown your PC to a true power off state (not soft off) - move the switch, power up PC & boot
     
     On the home screen of PX1:
    Do the fans indicate "Auto" in the display box?
    Is the chain link closed, to lock all 3 fans to the same speed?

    GPU-Z does not report the correct PWM fan speed for the first and second fans, and it does not report the PWM fan speed for the third fan.

    Windows 11 completely up-to-date.
    1.3.7 as visible from my screenshots..

    change the default bios on your GPU

     
    I am not using the OC vBIOS as that wouldn't even allow me to control the third fan at all.

    If they weren't on Auto then my custom fan curve would never do anything and the card would be running on its stock fan curve... so obviously, yes, it's set to Auto...
    It is, but it doesn't matter at all as I am not using a fixed fan speed...

    - just sitting idle in the desktop and looking at HWiNFO64, the card will reach about 60ºC on the core



    This is by design on the 3000 Series AFAIK including my 3080 XC3 and 3080 Ti FTW3..... they are designed to be Silent until a Load, like gaming is encountered. ( these chips are supposedly fine to 95° , so I assume EVGA knows what they are doing )
     
    If like me you don't mind the Fans and like to keep the GPU cooler then 1 option is to switch to Bios 2 (OC/Gaming Bios) and DON'T install PX-1  ( or simply don't let it start at boot to test this)  and all the Fans should run at 33% by default, using the built in Bios fan curve.
     
    I see 34% in GPUz without PX-1 running  ( same RPM on the Right Fan which maybe linked to Fan 2? as they are always the same RPM reading )  if you still see weirdness with no PX-1 running I would ask support and confirm latest Firmware and MU with them)
     
    Or 
     
    Override the OC Bios Defaults with  PX-1 if you want a more aggressive curve i.e. a bit more airflow in summer at idle say 40% at 30° etc

    33% is way too much, I can keep the card at about 27~28ºC with the lowest fan speed of just 15%.
    I just want to be able to use PX1 without having to worry about the fan curve, as there is no way to control the third fan with 3rd party tools.

    The OC bios, is a bit strange in my testing as Fan 1 and Fan 2 won't go below the Bios Limit of 33% but the "Right Fan" does,
    so you would need to use the Standard Bios but I would suggest you try slightly higher %ages eg 20% or 22% as many Fans do not work correctly, or even at all, when set to their lowest setting as they won't get the voltage needed to spin, so you many need to try it at 25% for eg. and go down 5% , if still good go down ( or up) another 2% etc until you find the % at which all the Fan will spin without issues.

    I can lower the fans down to 13% before they start randomly dropping out, that was never my issue.
    My fan curve works perfectly, as long as PX1 doesn't randomly untick "Fan Curve Control" on its own... which is the reason why I started this thread.
    Just flipping through the pages/tabs inside PX1 makes the "Apply" button go from greyed-out to clickable...
     
    At least one of the fans rattles, especially at lower RPMs, and I've heard it rattle at around 1200RPM which is about 40% PWM duty cycle.
    The noise does not go away even when using a fixed fan speed.
    Sometimes it rattles, sometimes it doesn't.. but it rattles most of the time. The card is and always was mounted vertically, not sure if that's relevant to the rattling or not.

    Ahhhh....... that went over my head, it is LONG time Issue with PX and why I don't start it minimized on Boot, I never figured out what causes it , but it does seem related to install new Nvidia Drivers in most cases, to me at least, so I now check it if I update Drivers , the 546 series doesn't work for me but 545 is okay it seems so far.
     
    The Rattle is only something Tech Support can help with , though in the past I have "fixed"  bad fans by press the center hub fairly firmly to make sure the fan is seated properly on the bearing....

    If reinstalling doesn't work, you could try downloading the latest version of Precision X1.
