The fan speed is controlled by the GPU BIOS. If you know your exact card model and BIOS (I think there was a tool to get them in TPU), you could re-flash it and see if it's fixed.
My graphics card model is Sapphire Pulse RX 6700XT. But I have doubts about GPU Bios flash. They say it is a very risky transaction.
I still don't think it was worth the trouble, is there any difference in clocks ?
Also does the "fan instability" prevail if you leave the load running for a while? Hysteresis (the difference in temperature in an amount of time required before the fan speed goes up) is a thing. If it eventually climbs up to an acceptable level that keeps temperatures in check, that's ok.
Actually, I want to test this too. Is there a program that can play without any measurement program on the game screen and create statistics of the temperature and frequency values in this process after about 3-4 hours?
Additionally, we will test my GPU on my friend's computer today. I want to be absolutely sure whether the problem is with the GPU or not.
It would be great if I could find someone else using the Sapphire Pulse RX 6700XT to compare it to, but I don't.
I found a solution, guys.
In the custom fan setting, the fan percentage was not as I wanted. When I tried to reach the rpm values I wanted by manually adjusting them one by one, I came to the following conclusion:
After adjusting this curve, I came to this conclusion in a 15-minute furmark test (1920x1080, 8xMSAA):
When you set it this way, it runs around 2000 RPM. Since the max fan speed of Sapphire Pulse 6700XT is 3500 RPM, I probably cannot get the exact values. I don't understand it exactly, but now I can adjust it as I want.
I cannot calculate it numerically, but I can say that I can adjust it as I wish, since I can determine how many rpm is spinning at which % value by changing the setting during the test.
Update:
The fan speed was entered incorrectly in the BIOS of this GPU. It should be written "-15" units less than normal fan speeds. So I learned how to calculate.
Thanks for everything guys.
