I have had my GPU for around 2 years, and I never had a problem until now.
I came back from a short vacation (5 days) prior to which the GPU was functioning like normal, and when I opened a game (Fortnite, specifically) its fans started going really fast and loud.

System Information:
Picture

  • ■ Operating System: Windows 7 Professional 64-bit (6.1, Build 7601) Service Pack 1
    ■ System Manufacturer: Gigabyte Technology Co., Ltd.
    ■ System Model: H97M-D3H
    ■ BIOS: BIOS Date: 04/21/15 13:26:41 Ver: 04.06.05
    ■ Processor: Intel(R) Core(TM) i5-4460 CPU @ 3.20GHz (4 CPUs), ~3.2GHz
    ■ Memory: 16384MB RAM
    ■ DirectX Version: DirectX 11

    GPU
    ■ Card name: NVIDIA GeForce GTX 960
    ■ Display Memory: 4095 MB
    ■ Dedicated Memory: 1960 MB
    ■ Shared Memory: 2135 MB

Issue information:

  • ■ Rebooting doesn't fix the issue but shutting down and then powering up does.
    ■ The GPU temperature is normal but the fans are really loud and really fast
    ■ When trying to control fan speed through MSI Afterburner, even the slightest speed up will put the fans at 100% speed and they wont go down
    ■ When the fans are at 100% speed, one fan spins constantly while the other one spins for around one second and then stops
    ■ Through SpeedFan, I can change the speed of the CPU's Fan and the Case Fan

Complementary information from GPU-Z, MSI Afterburner, Speedfan and GPU Temp


Things I have tried that did not solve the issue

    ■ Rebooting
    ■ Cleaning everything with compressed air
    ■ Unslotting and slotting the GPU
    ■ Changing the GPU's thermal paste and cleaning it more thoroughly
    ■ Plugging and unplugging the GPU's fans
    ■ Changing the PSU's PCI-E cable that was connected to the GPU
    ■ Doing a clean reinstall of the drivers through Nvidia Experience
    ■ Doing a clean reinstall of the drivers by first going into safe mode and uninstalling them through DDU (Display Driver Uninstaller)

Good question. The model of the fan that I used was an Apistek GA81STU - but check yours to make sure you have the same volt/amp specs and correct number of pins. When I got my fan, I found out that the mounting bracket was incompatible with my GTX-960, so I had to jerry-rig it by screwing it directly onto the fins of the heat exchanger. So...

This happened to me with the exact same card (GTX 960). Of the two fans on the card, I had to completely replace one of them (the one that "spins for around one second and then stops"). What was happening was that the other fan was going full speed because the other one was dying.

Thanks for the reply, did you replace it yourself? Was it complicated? Or as easy as using a screwdriver?

So it wasn't complicated really - I just had to adapt to make it fit.

Okay, I will try to find a compatible fan and then post an update. Thank you!
