RTX 3080 ROG STRIX OC fans spinning even at idle

Hi i just got my 3080 oc strix card and I don't know what to do because fans on auto wont slowing down at all. Even if card is cold like 32c fans are still going on 53% any ideas what to do? When I'm trying manualy change fans under 35% fans are starting spining and stopping over and over. I was trying quiet mode and performance but nothing change.

My card never goes under 50W of power consumption to stop the fans, with two screens >80W, with one screen it is about 70W, and even without a screen it was not lower than 50W.
I hope either it is a driver or vbios issue. And since performance is not affected at all, I do not think it is faulty hardware. And with another 3080 it worked very good - just switched because I wanted and Asus card. Hopefully at some time the support in Asia will respond to my ticket.

Another question I thought about was if for some reason a very old power supply can affect the power consumption of the card? I don't believe so, but who knows?
In my case, I am using an 8 year old 730W Xilence PSU, still doing its job with no (obvious) issues.


The problem is that the frequencies of wattage spikes triggers the fans to be sporadically ON/Off which is not good for the fans themselves, let alone this isn't how 0db should properly function.

If vBios (not via-drivers) can extend the wattage spikes even for 2-3 seconds and bypass the current threshold that is to short, that would fix it.

As far is your PSU? Don't use anything that is warned out, you dealing with power hungry and sensitive GPU, although it might still look like works OK I wouldn't trust it.

People don't realize and don't pay enough attention to how very important is PSU, I would say its heart of your system, don't let it fail on you, you know when that happens, very little you can do to fix it.

I have be quiet! Dark Power Pro 11 850W. So not the case here.

Dear all,
Please refer to below FAQ for the Fan Stop design for the 30 series card
https://rog.asus.com/support/FAQ/1044879
Thank you.


I hope this is a joke and not a real solution because your cards design doesn't follow that FAQ at all.

I agree, the FAQ's for 3090 do not fully correspond with 0db functionality.

There are times that the fans spin regardless of power draw and GPU's temperature.

New BIOS doesn't seem to have any impact on 0db for me.... still pretty much stuck at 1000 rpm

Like I said, this V2 BIOS made slightly better 0db mode compliance, but there are still spin ups even thou power draw and temperature are whey below 0db FAQs, but it's a less dramatic.

Did you check your cards power draw and temperature and if it's in line, check in CP power option "power management" if its set to moderate and not off and in NVIDIA CP and settings in there, in your case, something else is going on.

Hello,

Have you checked the power consumption of the card?

Sits around 50-55W and 30 degrees on idle... occasional power spike. Power mode set to normal in CP. It's perhaps slightly better than before, but still spending a lot of time with 1000rpm at "idle." The issue is probably more about what's causing the spikes, but maybe that is normal

With that power draw and temperature fans definitely shouldn't be spinning. Even with higher power draw spikes if the fans gets triggered, they should stop shortly after, unless something else is keeping power draw or temperature higher.

Do the fans stop at all or spin constantly, from the sound of it It sounds like they spinning most of the time, if that's the case, there is something off for sure.

Even with the previous Bios, fans would stop and say off, the problem was and still slightly is, 0db mode is so sensitive to power draw spikes, which is slightly better with V2, but still happens but again, not as dramatic.

will run GPU-Z for a while and see what graphs out... maybe I was just unlucky in that ever time I happened to check it was after a power spike!

Edit - tbh, I think the issue is the 50w power draw threshold, my card seems to want to idle just over that!
