I have an EVGA GTX 960 SSC. In the 900 series ACX 2.0, the default profile for the fans is stay OFF until the temperature reaches 65 °C. At 65 °C the fans are activated. This is great for normal use of the video card, but with hard usage like long renders in Blender 3D, although GPU temperature does not reach dangerous levels (no more than 70 °C in my case, 22 ºC in room, winter) but the backplate gets really hot, it burns when touched. So I fear for the health of other card components. Furthermore, the heat stays inside the case and is not well extracted out. The funny thing is that with the default hardware profile, I’ve never seen the fan to overcome more than 18% of speed.
This problem does not occur if from nvidia-settings (I have set “coolbits” option in xorg.conf) I choose in “Enable GPU fan settings” to 35%/40%. At that speed the GPU is kept really cold, the backplate is not so hot and the heat is extracted from the PC case better. But the problem is that in this way the fan is always ON.
So it would be nice to have more fan settings from the nvidia-settings GUI. For example be able to choose another temperature instead of those “65 °C” hardware factory, for example “50 °C”. So that way, the fans are activated at “50 ° C” and the fan speed is variable always trying to keep the temperature at 50 °C.
In short, incorporate features for better profiling the fans such as those Windows users can set through some applications, and Linux users can not use.
Thank you very much!
