There is only one reason why the fan is spinning so fast, and that is because the temperature is too high.
Check the temperature of your various components. If the speed is described as crazy, it is estimated to be 70 degrees.
If you are too lazy to disassemble the phone, just buy a cooling base. If you know how to disassemble the phone, clean the dust and re-apply silicone grease.
This is probably because your new driver can increase the speed of the cooling fan according to the temperature of your graphics card, so the noise is louder.
In other words, the temperature of your graphics card will be high when you are watching video, and the driver is protecting your graphics card by increasing the fan speed.
I think this is probably the case
