My GPU is stuck at 30% & 1000 RPM FanControl

[Ploxin62]

Hello, today I saw that first my CPU & then the GPU have a weird "?" infront of the %.
It says that something is overriding the FanControl Curve & I honestly don't know what that could be.

On my CPU, it basically disappeared after activating the "force apply" setting (sometimes it comes back & then goes away again), but on the GPU, it's still here & doesn't disappear even with force apply setting on.

I uninstalled GPU Tweak from Asus & that still didn't help. Previously, I used the MSI Center Software to control my fans on everything, but then I switched to FansControl.
This issue somehow came up a few days after I uninstalled the fan assist app from MSI Center.

Important Specs:
-CPU: AMD Ryzen 7 7800X3D
-GPU: ASUS TUF NVIDIA 4070ti Super
-Mainboard: MSI B650 Tomahawk WIFI

For your CPU, most likely something else is setting % from times to times, most likely your bios curve. For Nvidia GPU, the [1-29] range is not available, so your 13.3% on your screenshot is not valid, and will snap back to 30%, the minimum allowed. 0 RPM is possible at 0% if you set the appropriate checkbox in the sensor settings.

You want your GPU curve to look a little like this:

For the CPU I think so too, but how can I fix that? Also for the GPU thing, it worked previously, so I don't understand why it shouldn't work now tbh.

Isn't 55 - 0% too low? I mean, when I play I would like to get it cooled before it reaches anything above 50 tbh

This is how my GPU curve looks

[Ploxin62]

After updating & checking the setting for 0 RPM on Sources, nothing changed. It's still running at 30% & 1000 RPM constantly.

EDIT:
I changed the Curve to this:
-25 Degrees - 30%

Now it's gone & constantly running around 30%, which is something I cannot change as far as I understand everything here.

The "?" on the CPU Curve still appears, how can I fix it in the bios?

[Rem0o]

You need to remove any type of auto fan curve in the bios. Best is to set a constant manual speed in there.

Okay, will try & give feedback. Thanks

I disabled "Smart Fan Mode" & set every fan that is connected to the mainboard to "PWM" & put the fans at 50% no matter the temperature.

It still gets overridden by an external source. I don't know if the mainboard is the issue, maybe you could help me? I took a picture of my bios how it looked prior to the change, maybe you could find something to change.

It's the same for the CPU fans.

I've got the same motherboard, and found that DC mode worked best for SYS1-6. I had issues with PWM mode with the B650 Tomahawk SYS1-6. PWM may work on CPU & Pump although I'm using a separate NZXT Kraken controller for those. Excerpt from the MSI manual in the image below ,which suggested it as default when non-auto with different default settings for SYS vs. CPU / PUMP. Good luck!

Also, I can't remember if I was using the default LibreHardwareMonitor or a different release directly from there git, as initially it couldn't see Sys5 & Sys6, which I think was the fix for that, although i'm not 100% sure as I was messing around with a few things all at once.

[Ploxin62]

Thanks I will try but don't know if this will help me since it's showing the "?" on both CPU Fan & SYS1.
Previously, it worked fine. I don't know why all of an suddon something else is trying to take over the fan control..

I have the same issue on my ASUS TUF 4070 ti super.
Mainboard is ASUS ROG STRIX B550-E GAMING
Nvidia 0% hardware curve override is on as well as force override.
I uninstalled pretty much every software related to mainboard and GPU, even Geforce Experience and tried both the Performance and Quiet BIOS on the GPU.
Tried both custom graphs, setting speed to zero below 50° as well as linear graphs with Min temp 50°.
The only 2 ways to stop the fans from spinning, is either turning off any fan Speed Control, in any Software, or, on top of that, enable 0dB Fan in ASUS GPU TWEAK III (which will also disallow a custom curve).

What's also weird is on the Geforce experience overlay, under the performance section, you can actually see how it switches from "Automatic" to "Manual" with a fixed speed of 30%, whenever one of these overrides occurs.

Since not even the ASUS software can properly deal with that, I strongly suspect this is a problem with ASUS hard- or firmware.

Anyway, great piece of software @Rem0o it is such a big leap in noise/ temp profiling 🙌. Also so much fun tampering with it 😄

I am a big fan of your fantastic tool and sent you money several times. Really excellent tool.

However, sadly, for the last ca. 2 months, it has no longer been able to set the fans of my GPU (Asus GeForce RTX 3060) to 0%. It used to work great before.

Please see my attached setup. I used to have one of the GPU fans set to 0% up to a certain threshold. The other fan was set to always run at the lowest possible RPM, which in my case is around 685RPM. Now, I need to let both fans run at 685RPM since setting one of them to 0RPM means the setting is ignored and it is set to around 1000RPM.

Specs:

• CPU: Intel 12700K
• GPU: Asus GeForce RTX 3060 (Nvidia Driver 560.70)
• Motherboard: Asus ProArt Z690-CREATOR WIFI
• OS: Windows 11 Pro 10.0.22631
• FanControl: V198

I have not changed any software setup on my machine. I only updated Fan Control and it suddenly stopped working. Unfortunately I don't know when exactly that happened. Specifically, there is no other software on my machine (that I am aware of) which controls the GPU fans. Same goes for the BIOS which only controls CPU and motherboard fan headers, not the GPU fans.

I already enabled the "Force Apply" feature in Fan Control, to no avail.

I also checked the FanControl logs and there has not been any log output for the past few weeks.

Overall Setup:

GPU Silent Curve:

It would be great if you could check the last ca. 2 months of changes to see if anything could have affected the 0RPM feature of the GeForce RTX 3060. Judging from this thread, other NVidia GPUs are affected as well.

Many thanks and thanks for all your hard work on this invaluable tool.

First thing make sure you got the 0% nvidia setting checked in sensor settings.

Second thing, did you change monitors or add a second monitor? It is common for nvidia gpus with multiple monitors to refuse going 0 rpm due to the higher idle load.

Also, do you got afterburner in the mix?

[chrisgleissner]

Thanks for your reply.

I found the GitHub page on which you have a screenshot of the settings where you can enable the 0% Nvidia setting. But even after much searching in the UI of Fancontrol, I cannot find this screen. How can I access it?

I don't use Afterburner or any similar software.

I have a dual screen setup. Both are 4k and both are connected via HDMI. One of them is additionally connected via DisplayPort and the Gpu mirrors the same signal to both Hdmi and DisplayPort. I have not changed my screen setup in years, but I did enable the screen mirroring recently. I will see if disabling it makes any difference. You are absolutely right. I did read about the 0rpm mode being disabled if power draw exceeds a threshold, and maybe I am just above with the mirroring.

Thanks for the idea.

I did some more investigation. The 0rpm mode works correctly on a freshly started system. It appears that at a certain temperature and/or watt usage, the Gpu no longer permits this mode and the (force) override attempts of Fancontrol don't work. I presume this is simply a hardware limitation. Either way, even without this mode, Fancontrol allows me to set the Rpm to 685 which is low enough to be basically inaudible in an idling system. So I am happy and this is a non issue. Thanks again for the great tool.
