My HP CQ40 409AX laptop, the fan is ringing, do I need to replace it?

It's normal for fans to be loud when running large programs or games. 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 working frequency of the CPU is low, 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 is running at full speed, and the fan will also run at full speed, and the sound is naturally slightly louder. However, it is impossible to tell whether 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 whether the fan is faulty.

HP's junk products have been on the party, it is recommended that you try the cooling pad, if it doesn't work, just change the book, HP's customer service is super expensive, it's better to buy a new one, remember not to buy HP.

If you still have such a problem after cleaning the dust, you need to contact the repair center to check whether there is a problem with the fan, and you may need to replace the fan to solve it.

HP's heat dissipation is really bad, and there are inferior products for a while, if there is a problem with the computer itself, it is recommended that you buy one.

CQ-40 Buy a cooling pad will use it, I didn't watch the 315 party the year before last, and I dare to buy the HP CQ series.

cq42-151

I'm also very entangled in this problem.

Reasons and solutions for HP laptop fan sound:

1) This is due to the fact that the lubricating oil of the roller in the CPU fan has dried up, resulting in a lot of friction, and the friction sound emitted, or the dust is mostly stuck, will make a sound.

2) In such a situation, as long as you open the back cover of the notebook, use a brush, and clean the dust on the cooling fan.

If the notebook is just disassembled and cleaned the fan, we are 50 yuan at a time, I am from Chongqing, and I should be able to talk about the price, but it is just a matter of how much he earns and how little he earns.

It's OK to remove it yourself and clean it up with a brush, which is much easier than disassembling and assembling a desktop computer, and you don't need to waste money.

1.Generally speaking, there are devices such as cooling fans inside the notebook, and due to its mechanical structure, it will produce a certain amount of noise during high-speed rotation, so it is normal for there to be a certain amount of noise.

2.You can try to turn on the computer and click F10 to enter the BIOS, select System Configuration, change the Fan Always On option to Disable, and then click F10 to save to exit and try it.

3.In addition, if the fan is loud, it means that the heat dissipation demand of the laptop may be greater, so the fan work intensity is high, you can consider using a raised laptop or installing a heat dissipation base to help assist in heat dissipation.

Hello, welcome to HP products

When the internal fan of the notebook is operating normally, it automatically adjusts the speed according to the amount of heat dissipated by the hardware, and it is currently rotating at a high speed.

After pressing the F10 button continuously to enter the BIOS during boot or restart, select the System Configuration column Fan Always On The right option is disabled and off, and then press the keyboard F10 directly and select Yes to exit, the notebook will automatically reboot back to the original system to see if the normal operation of the fan can be restored

I hope the above reply is helpful to you.

1. The internal heat dissipation of the notebook is that the fan automatically adjusts the speed according to the heat dissipation to achieve heat dissipation, if the notebook is obviously hot and the fan sound is louder, the notebook is slightly higher to ensure the air circulation at the bottom, and observe to see if it can be improved. Observe whether this phenomenon occurs when using the battery alone and the external power supply alone, and if only the external power supply appears, replace it with another power outlet and try again.

2. Pay attention to whether the fan sound is always loud or intermittent, such as running large-scale software games, etc., the fan speed increases and the sound becomes louder. This is because when the system detects that the program is running at a high power, it will increase the speed of the fan to prevent the machine from overheating.

3. If the fan has been loud to avoid overheating or hardware problems, it is recommended to contact the local HP Care Pack service center to detect the specific cause and repair center.

Are you switching to an original fan, or a replacement? The feeling you describe is that the temperature control function is not activated. Or did you change the fan line.

In addition, it should be noted that if a 32-bit operating system is installed with 4GB of memory, it will not fully utilize the full capacity of memory due to the limitations of the memory mapping access of the system itself, which is normal, and it is recommended to install a 64-bit system in order to fully identify the memory capacity and use it.

The computer temperature is too high, take the computer apart and clean the cooling fan.

We hope you find the above reply helpful.
