I had this exact same issue on my strix 3090 until I learned something - I was using GPU-Z to monitor my board power draw, and having that program opened, for whatever reason, caused the power draw to be higher. As soon as I close that software, and just let PC sit idle at desktop with nothing opened, the fans will stop. If you will use HWinfo to monitor board power draw instead of GPU-Z it may have the same affect for you.
I run a UltraWide 3440x1440 120hz display and a 1920x1080 72hz display. My power draw with gpu-z would sit at 54w, and fans would never stop. I toiled over the issue for a while. If I turned off one of the monitors the fans would stop, but with both on I never could get it to stop. Then I eventually realized that when I closed hardware monitoring the fans would stop. I realized it was gpu-z so I stopped using it and fired up hwinfo. I could then see that power draw at idle was around 40-45w now, and the fans will stop. Once the fans stop, they will not spin up again until temps go over around 50c, even if board power draw goes back over 50w occasionally. So the rule is for the fans to stop, temps need to go under 50c, and board power draw needs to drop under 50w. For fans to spin back up, Temps only need to exceed 50c. Now that I understand how it works, the feature works great. I also noted in my hours of testing after getting the card, that having MSI Afterburner sitting open on 2nd monitor gives me lower Port Royal benchmark scores - by about 100 or so points. I verified it over multiple runs. So, the takeaway is that some of these apps sitting open monitoring your hardware do use some system resources, enough to make some minor impacts. HWINFO, for whatever reason, has never caused me any negative impacts that I've seen....Perhaps it is because it has hardly any GUI - its just like a spreadsheet readout.

Hi, thank you for the answer ! Unfortunately in my case it does not fix the problem. Using hwinfo and both monitors (1440p240hz - 1080p120hz) the power draw is still above 50 and the fans never stop. One thing i saw is that when windows is starting i get a 140w spike which cause the fans to start and they never go down after that because of my idle power draw. Ã‚*

It should be possible to set a custom fan curve to bypass this if one is using multiple high refresh displays. Also, as stated by another user make sure there aren't any applications drawing unnecessary power from the card at idle.

Hi, and thank for answering.
Yeah i will try a custom fan curve.
Any plans for further bios updates ?
I tried with only one monitor but still draws 56w idle with a fresh windows install so maybe bumping up the idle wattage threshold would help.Ãƒâ€š*
