I have this setup:
-
Motherboard: ASUS Prime x570-Pro White
-
GPU: Gigabyte nVidia RTX 2070 Super 8Gb
-
Windows 11
-
latest nVidia drivers
The problem: my GPU fan is too noisy and I can not control it.
Some details.
The issue exists only during gaming and and the exact symptoms are the following: when the GPU temp reaches around 70-75c, the GPU's fan speeds up to 100% for 1-2 seconds and then slows back down. Then there's some low RPM period and then again 1-2 seconds of 100% speed. These low RPM periods could be from 3-5 seconds to 3-5 minutes.
I've experimented with the following apps:
-
Gigabyte control center
-
MSI Afterfurner
-
FanControl
All these apps have a feature of custom temp/rpm curve. My goal is to configure such a curve, to raise the fan speed slowly and predictably. I configured a curve with some idle section, another with a 100% speed when the temp is really high, and several sections in between with some reasonable fan speeds.
Nevertheless, I observe that the fan time after time jumps to the 100% speed 1-2 second periods ignoring my curves in any app.
For example, In my curve the RPM supposed to be 60% when the temp is from 50c to 80c degrees. But in fact it again starts jumping to 100% time after time when the temp is around 70-80c degrees.
Need to mention than I've managed to configure every app in a way, that I can clearly see that it actually controls the fan. I can completely stop it, for example, or configure a constant RPM. And overall the curve works, except these unpredictable jumps to 100% speed.
I need help and/or advice with that. What do I miss? Where else to look? Is there anything low level in my system overriding my custom curves and forces the fan to go to 100%?

I have a Zotac Nvidia 1080 Ti and the fans eventually go crazy. I have monitored this with GPU-Z log but couldn't find any logical correlated parameter that could explain this functioning. I have uploaded it to imgur: https://imgur.com/tHaamBA. What is more strange is that the column Fan Speed (%) does not change; it always shows that fans are at 50%, as this is the fan speed I set for temperatures between 40 and 50 degrees. However, the RPM can go > 3000 as shown in the image. Can this hurts the GPU or the fans? I have read that it could be a PSU bad connection problem. Have you experienced anything like this before? PS: no black screen malfunctioning or something like that happening.

I'm having a weird problem with my GPU fans.
When they start from 0 at the lower % (30%, gigabyte 2060 card) the fans spin and stop, like it doesn't have enough momentum to keep spinning.
At 40% they go normal and going back to 30% after that is okay too.

Red is when starting the test setting 30% with MSI afterburner, orange is 40% and yellow is 30% again.
This is from GPU-Z while idling/browsing:https://i.imgur.com/tzxux4d.gif
It seems to do it intermittently: https://i.imgur.com/7am3Mln.gif
What can I do??
EDIT: after some digging, it seems it's a know behaviour of the gpu.

The video is exactly what happens to me and the results of 30% fan speed vs 40% are the same
