Sapphire RX 460 Fan goes to max speed and back down for no reason

Greetings Everyone!

My RX 460 fans are having problems lately. For some reason, the fan on my GPU goes up to the max speed 3200+ RPM then goes back down to it's normal speed. This happens randomly for no reason even when the GPU is only at 30 degrees and whether the PC is just sitting on idle or browsing the internet and it lasts from less than a second to up to a minute. On GPU-Z whenever the fan ramps up, the fan percentage is on 27% but the RPM is at 3200+. But when the speed goes back down the reading becomes correct like 27% with 1300+rpm. Same reading can be found in MSI Afterburner. 

It also won't follow the custom fan curve whenever it ramps up to the max speed

This also happens in BIOS and safe mode

Here are the things I did:

-Set a custom fan curve

-Uninstalled MSI Afterburner

-Reseating the Graphics card

-Using DDU to reinstall the drivers several times

-Updating the drivers to the latest version

-Cleaned the GPU and the PCIE slot (I didn't change the thermal paste though)

-Reconnected the GPU fan

-Reset the BIOS

-Updated the motherboard BIOS firmware to the latest version

-Replaced my PSU

But none of these fixed the issue.

My Specs:

Motherboard: Asus H81m-D

CPU: Intel Pentium G3250 (I know this sucks but i'm about to upgrade it soon)

GPU: Sapphire RX 460 2gb Single Fan

RAM: 8gb DDR3 1333mhz

PSU: Silverstone strider essential series 500w

As you guys can see, I have a fan curve set but the fan speed/rpm still goes up to 3319rpm even at idle temps which is 30+Fan curve.png
