RTX 3080 zero rpm not working

Hi there
I got a used Palit RTX 3080 Gaming pro oc today.
Installed perfectly and all is good appart from the fans. Its gone into my near silect pc and I just cant get the GPU fans to run under 30%.

I have trawled the net for answers but just cant find anything that works. I have tried Palit Thunder master, MSI afterburner and fancontrol. Running the newest drivers and BIOS.

The card is sat at 46C and gpu usage is between 0 and 1%.

I would appreciate any help if possible?

Cheers
Gwyn
 
Are you using multiple displays or a 4K high refresh monitor which is keeping the GPU running at higher idle clocks?

Palit cards and zero RPM can be a bit hit and miss, I had a Palit 1070 which was advertised as having it but the production model did not and from a quick Google a few people have had issues with it on the 3000 series Palit cards - some of them have updates available to fix it.

46c with 30% fan? Sounds like it's not getting down to its idle speeds/voltage. I was messing with this last night actually trying to get zero rpm to work with a custom fan curve and at idle with 30% fan on an FE card it was about 30 degrees.

Using totally stock card how long are you waiting for the fans to stop? On the FE it can take quite a while before they stop.

If you are using a custom fan curve it seems very hit or miss if zero rpm will work going from experience.
 
I’m running at 1440p with a max 85hz. I’ve tried it on the default fan curve and custom curve and neither stop the fan. I was just surfing the net last night for a couple of hours and the fans never stopped.

As pointed out above, something is not right with your idle temps.

For instance, I have a 3080 TIFE, which is currently showing 27C at idle, with fans at zero.

If you haven't already done so, I'd be taking the card out and giving it a good clean, and perhaps be looking at repasting it.
 
3080 fe currently at 58c while surfing net and watching stream , 1440p 240hz fans at zero

room ambient 22c , its not idle browsing web constantly scrolling + watching streams

fans kick in at around 60c

Doesn't sound right, considering I have the same card, with the same cooling solution, albeit a TI, and my idle is currently at 28C.

I do have a twin fan cooler sat below it, though I doubt that accounts for a 30C :eek: difference at idle.

its not idle im browsing the net while watching streams, it settles to around 30-35c idle zero fan, gaming loads are around 70c
 
Thanks for all the replies. It was late last night messing with it. Going to try again tonight and get some figures up here. If it is running hot, might have to redo the thermal paste.

Have you tried uninstalling all of these softwares? It might be that the custom fan control is what is preventing zero-rpm mode. I don't think zero-rpm mode and setting a fan curve below 30% is necessarily the same thing, since the VBIOS may handle this with a different algorithm.

I’m just doing some testing now but currently sat at 30% fan and 47c whilst idle in windows.
Just ran 3D mark and it maxed at:
GPU 77c
Mem 86c
Hot spot 87.2c
 
My 3070FE is sitting at 40C idle (room temp ~21.5C) with the fan at 0 RPM, friends 3080FE is sitting at 40C idle as well with 0 RPM, which to me sounds like the normal situation with 3000 series cards in current temperatures. The fan on my 3070 doesn't kick in until over 60C.

EDIT: I have the case fans backed off at idle for noise purposes, could probably drop a bit off that with them at normal speeds.

What power is the GPU using while in idle , can use gpuz or hardware monitor

According to GPZ:
GPU 1710MHz
Mem clock 1887.7MHz
Board power draw 96w
GPU chip 16w
MVDDC 63w

At true idle as in on desktop with nothing running I'd expect board power to be ~20w and clock speed ~200Mhz.

So something is keeping the GPU in a higher power state. Have you changed windows power profile at any time? Most run this on balanced.

And in Nvidia control panel have power set to adaptive not prefer performance or whatever it's called. I'm not at my PC to check.
