Recently, a user said that after his computer was shut down, there was a problem that the CPU fan was still turning, and after waiting for a while, the CPU radiator fan did not stop, so what should I do if the CPU fan is still turning after the computer is shut down? Below I will bring you the method to solve the problem that the CPU cooler is still spinning after the computer is shut down.
Reasons and solutions for CPU fans to turn on after the computer is turned off.
Method.
1. The motherboard BIOS is set incorrectly
Generally, the CPU cooler fan is still rotating after the computer is shut down, and most of them are caused by the wrong BIOS settings of the motherboard. After powering on, press the DEL key on the keyboard several times to enter the BIOS, find the ACPI option in the BIOS interface of the motherboard, select [EABLED] with the up and down buttons, press [F10] on the keyboard to save the BIOS settings, or find "Load Default Setup" to restore the default settings of the BIOS. However, due to the different BIOS settings of different brands of motherboards, here is a simple way to restore the motherboard BIOS to the default settings, we need to open the main chassis, remove the round coin cell battery on the motherboard, and then install it back to restore the BIOS default settings.
After we find the coin cell battery on the motherboard, we flip the buckle outward, and then the coin cell battery will automatically eject, and the coin cell battery will be removed, and we can install it in place.

It's normal for fans to be loud when running large programs or games. This is due to a technology, that is, when the system runs some small programs, the CPU will work at reduced frequency, for example, it may work at a low frequency, the CPU works at a low frequency, and the natural fan does not need to run at full speed, at this time, the sound is relatively small, when running a large program, the CPU runs at full speed, the fan will also run at full speed, and the sound is naturally slightly louder. However, we can't tell if the fan sound you are talking about is normal based on your text description, if you feel that your fan sound is really abnormal, it is recommended that you contact HP's repair center to check and see if the fan is faulty.
