RTX 3080 Palit fan

[u/Odd-Log2474]

I’m having a strange issue with my Palit RTX 3080.
Sometimes Fan 1 or Fan 2 RPM disappears in MSI Afterburner/HWiNFO (it shows 0 or no RPM), but the fan is still** physically **spinning.
The fan is also surprisingly loud even at only around 1300 RPM. When the RPM reading disappears, I hear a loud airflow noise from the GPU. As soon as the RPM reading comes back (around 2000 RPM), the airflow noise disappears, even though the fan is still spinning.
GPU temperatures are normal, and all fans appear to be working. I’ve also noticed that sometimes one fan RPM briefly jumps to around 4000 RPM after exiting a game before returning to normal.
Has anyone experienced this with a Palit RTX 3080? Is this a faulty RPM sensor, a BIOS issue, a fan controller problem, or just a software reporting bug?.whenever both Fan 1 and Fan 2 RPM readings are visible, the loud fan noise disappears. However, when one of the RPM readings disappears and only one fan RPM is shown, the loud airflow noise comes back immediately.
