Question Why is my GPU fan not spinning?

Good evening, I'll try to explain what is happening as briefly as possible. Recently my GPU fan has stopped spinning properly, it's not like it's at 0 rpm always, but it simply fails sometimes. The problem is, it behaves differently each day, there are days that it'll work perfectly the whole day and other days the fan won't turn on at all! The most interesting part is that in a good day, it will keep itself at a nice ~1200rpm, going up to even 3000rpm when it really heats up but it can't manage to keep that for long, going back to the usual 1200rpm and sometimes failing back to the 800, 500 and then 0rpm. It's not that the GPU isnt heating enough for the fan to turn on, it was set to always be at 30% speed at LEAST, but I've had it running at 800rpm until my GPU reached ~80ºC and then it sped up to ~3000rpm and then started failing and making weird noises, back to the ~800rpm.

As you can see, the fan is set to 38% and it's still at 0rpm. I already tried to set up the speed in MSI Afterburner but it didn't help, everything is perfectly connected and I already tested this same GPU in a friends computer and I had the same issue.

On a very funny or sad sidenote, as I was writing this topic, my desk stopped shaking, which I realized usually means that the GPU fan is about to turn on and function, I clearly heard the sound of the fan speeding up and switched to HWMonitor to find this:

The fan was spinning at an astronomical 3186rpm for no reason at all, when it was set to 38%, which then quickly dropped to 800rpm for a couple seconds, and then back to 0rpm.
Would buying a new fan for the GPU fix the issue or should I buy a new one? I really don't have the cash for a new one at this moment.

My setup is:
Motherboard: Asrock H310M-G/M.2
CPU: i5-9600k
RAM: 16gb HyperX 2666mhz
GPU: GTX 1060 6GB MSI
I also have a 550w supply.

It seems like you have a faulty GPU.

But try setting a fan curve in Afterburner to see if you can over-ride it.
Well you obviously didn't even read everything I wrote since I already mentioned the MSI Afterburner, thanks for the input anyways.
