According to your description, I suggest you refer to the following information:
1. It is recommended that you turn off the option of long fan rotation in the bios. Please follow the following steps:
Please open (or restart) the HP (or COMPAQ) interface, select the system configuration, set the fan always on as disabled (or uncheck the box above), and then click F 10 to save and exit.
2. If your problems often appear, I suggest you contact the maintenance center for testing.
You can check the nearest HP Gold Service Center through the following website:
