GPU Fan Speed Fluctuating Randomly Even After Replacement – Acer Nitro V 15 (ANV15-51)

Hi everyone,
I’m using an Acer Nitro V 15 (ANV15-51), and about 8 days ago, I started noticing that the GPU fan speed fluctuates randomly. It suddenly speeds up to maximum and then slows down again, even when the laptop is idle or under light use.

I thought it was a fan issue, so I replaced the GPU fan 3 days ago, but the same problem is happening again. The fan keeps ramping up and down without any clear reason.

Has anyone experienced a similar issue or knows what could be causing this? Could it be related to the GPU temperature sensor, thermal paste, drivers, or BIOS settings?

Any help or suggestions would be greatly appreciated.

Thank you!
