Whenever I use user-defined automatic fan control on MSI Afterburner, the GPU fans ramp up to around 2000 rpm for about 1-2 seconds and then fall back down to the appropriate speed (see first 3 attached pictures).
This only happens when I open MSI afterburner. By default the GTX 980 doesn't start its fan until the temps are about over 60C, so the fans are fine until windows starts up MSI afterburner. I tried turning off start with windows. The GPU fan remains at 0rpm (this is normal) until I open MSI AF myself.
I tried v3.0.1 MSI AF and also EVGA Precision, same thing happens. It only happens when the computer (or I) open MSI afterburner/EVGA Precision for the first time until reboot (with user-defined automatic fan control).
Since the GPU fan is fine when I turn off user-defined automatic fan control, and it only happens once every reboot (when MSI AF/EVGA Precision opens), I came to the conclusion the user-defined fan control is causing this.
I'm not sure when it started happening, but I am sure that it wasn't happening before. Has anyone have this issue? I'm on nvidia 350.12 driver.
Someone over at Tomshardware told me that this is normal: "it will rev the fan at the beginning to test it its not a bug." But I'm pretty sure about 4 days ago, when I startup my computer with MSI-AF, I didn't hear loud fan noises..
It should normally look like the 4th attached picture; the fan RPM starting at 0 and then curving to the appropriate speed.
