SOLUTION: TICK "Force fan speed on each period" ON AFTERBURNER'S FAN SETTINGS.
--------------------

Hello everyone,

I am having a VERY weird problem with my GPU fan curve using MSI Afterburner. MSI GTX 1080 Armor, it has two fans. I had updated my drivers to 511.23. After this I noticed MSI Afterburner cannot control my right fan anymore.

It's constantly at 100% while my left fan reflects my fan curve or whatever I set it to. I noticed the right fan only goes full speed when MSI Afterburner turns on at system launch.

I've linked my fan settings in Afterburner. Issue persists even after rolling back to 472.12 drivers with DDU. What could be happening here?

Edit: Apparantly not linked to Afterburner. Still investigating why...

Edit 2: The fan ramps up as soon as the NVIDIA icon shows up on my taskbar. Some more trial and error shows the right fan ramps up to 100% as soon as I enable Afterburner's fan control.

Edit 3: It's not just Afterburner, does the same thing when I change fan speed from FanControl as well.

Hello,
Since my old post was marked as "SOLVED" I couldn't edit it anymore and wanted to post this here in case anyone suffers from the same issues. I had written "SOLUTION: TICK "Force fan speed on each period" ON AFTERBURNER'S FAN SETTINGS. " however this only worked until I restarted my PC.

The final solution was to replace the fan itself. There were already issues with this fan from the left fan randomly stopping but I never thought a hardware problem could cause a single fan to run on 100% all the time, especially since it only happened when I launched any fan control program... So there you have it. Probably was a faulty cable or something.
