According to your description, I suggest you refer to the following information:
1. It is normal that the notebook fan is loud when it is turned on or running a large program or game.
2. This is because when the system runs some small programs, the CPU will work at a reduced frequency, and the CPU's working frequency is low, so the natural fan does not need to run at full speed. The sound is relatively low at this time. When running a large program or turning it on, the CPU will run at full speed, and the fan will run at full speed, and the sound will naturally be a little louder.
3. After all, we can't judge whether your fan sound is normal simply by your written description. If you think that the sound of your fan is really abnormal, I suggest you contact HP's service center for testing to see if the fan is out of order:
