RTX 3080 ROG STRIX OC fans spinning even at idle

[pjeruk]

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.

Undervolting is a nice idea, but not on idle power state.
For me, it really seems that the VRMs are not idling as they should. In HWInfo64 I found the VRM temperature reading, and assuming "PWR_SRC Power Draw" from GPU-z is the consumption of the VRMs, it would make sense to me, since the temps are pretty high.

Now watercooled, the GPU on idle is less than the water temp - so it should be idling correctly. The VRM temp is on idle not less than 40C, also cooled by the GPU waterblock.
The card itself is working totally fine, getting a score of more than 13100 in Port Royal, so it is hopefully possible to be solved by a bios update - since my power bill would be glad for 30-40W less while being working on my PC.

No one should have to go to lengths of undervolting their cards that are design to run at certain speeds with 0db feature, that idea its definitely not a fix, its temporary patch, this should be fixed via new bios update

So I handed over the GPU to the service center. I described every piece of information I had to the staff and fixated that the problem occures for side fans. Not exactly sure what they did, guy who gave it back to me said they've changed/replaced the fans but as far as I can see it is the same fans I had before (they have some marks/cuts). But after that fans' RPM doesn't go above 1000 RPM all of a sudden. Even when I have temp apound 55-60 0C they keep cooling at around 1100 RPM. I have not yet tested it on big recent releases like AC: Valhalla or CP2077 but in every other game or EVEN idle it has no effect as it had before. Now this is as described one of the most silent top GPUs on the market.

I can't confirm the "silent" part at all, unfortunately. My card becomes super noisy, especially in recent titles.

Running CP2077 with RTX on at 1440p and the fans ramp up to 2500 RPM, which is SUPER loud. Temps are ~72°. Granted the card is pinned at 100% utilization and power limits, so this is a worst case scenario, but sill... It's everything but quiet.

Bios V2 is out now.
Is it worth to update?

I have just updated to V2 and this Bios seem to address most of the premature fan start-up.

Although, there are still some random fan start up that will spin for good amount of time when watching 4K YouTube videos, even thou power draw is less then 100W and temperature below 35C, but It's a lot less dramatic, so It's OK update.

Hello,

A further VBIOS update will be coming to address the fan threshold. Expect it to drop on the support pages within an ETA of a month's time.

Dear all,

Thank you.

That's it? that is the fix, I hope not:(

Its been said previously that the fans will spin even at 30-32C because of the short wattage spikes and supposedly vBios update that would address that was going to be release.

I really hope this isn't the "fix", if I ever have to mount the air cooler again, e.g. when selling the card.
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.
