Relatively recently my GTX 980 seems to have picked up this bad habit of not really paying attention to how I set up the fan settings. It will report as running at 90% fan in GPU-Z as well as in Afterburner 4.2.0, but if you look at the tachometer..... Even when under a load it will run the fans as it's supposed to for some time, and then after what seems like a random amount of time it will simply stop running the fan that's over the GPU core..... Even when it's under load! Rather annoying when you're trying to game (or in most cases run Einstein@Home via BOINC) and your temperatures shoot up to 80C core on a relatively light load.

Issue also occurs on 368.39 drivers. Haven't tried rolling back to the 362.xx drivers I was running before.

Rig is J├ĄgerWulfe as in my sig rigs, but for those who have such turned off (or are on the mobile site)...
CPU: i7-4770k
RAM: 16GB G.Skill DDR3-2400 CL10
Mobo: Gigabyte GA-Z87X-OC
Video: MSI GTX 980 Gaming 4G

Secondary fan runs perfectly fine, and the fan over the core does spin.... Sometimes even at the settings I give it, but usually it drops right down and just barely runs, operating at 150-400rpm for a few seconds at most and then drops right back down to 0rpm.


^It is said a picture is worth a thousand words, so..... Here's how the GPU fan tachometer looks for my GTX 980.



Thanks in advance for any assistance as, this is driving me up the wall trying to figure it out.
