Why is the fan loud when I bought a new computer?

Under normal circumstances, the higher the speed of the cooling fan, the louder the noise will be.

There are several reasons why the cooling fan becomes louder:

1. The weather is too hot, and the inside of the chassis continues to be high, which makes it impossible to dissipate heat in time, resulting in the continuous high-speed operation of the cooling fan, resulting in louder noise.

Solution: Use the machine in a cool room or turn on the indoor air conditioner to control the room temperature to prevent the indoor temperature from overheating and affecting the computer. If you are using a laptop, it is recommended to purchase a cooling base to assist in heat dissipation.

2. The computer has been used for a long time without cleaning and maintenance, and a large amount of dust has accumulated on the cooling fan, and the dust accumulation and friction between the shaft or the shaft and the bearing cause the running noise to become larger.

Solution: The desktop can remove the side cover of the case and remove the fan dust with a professional dust cleaning device; The laptop can be cleaned with a soft-bristled brush and dust blower to clean the cooling fan.

3. Running large-scale software or games, the CPU works at full load, and the heat dissipation increases. As a result, the cooling fan will run at full speed, resulting in louder noise.

Solution: It is recommended to go to Task Manager and end the process with high CPU usage. When running large programs, try not to run other programs to reduce the workload of the CPU and thus reduce the noise.

Example: (The following describes how to find a high CPU usage, but the program is not limited to the following programs.)

Right-click on the blank space of the taskbar to bring up "Task Manager";

In the "Task Manager", click the "CPU" column header, and the Task Manager will sort the CPU usage by type.

Select a higher program or processRight-click, select "End Process" or click "End Process" in the lower right corner;

4. The internal wiring of the chassis is abnormal, resulting in friction between the cooling fan and the wiring, and the noise increases; (Split desktops only).

Note: The content of this article is intended for your learning and reference, Lenovo does not recommend that you expand, upgrade, or replace your hardware device by yourself, as such operations are risky. If you have any of the above needs, we recommend that you contact your nearest Lenovo service location for professional support.

This situation is mostly caused by non-professional disassembly, when Lenovo split desktop machine leaves the factory, the wiring harness has been bundled and sorted out with cable management tape, after disassembly and assembly, please try to restore it to avoid abnormal noise.

Can the speed of cpu 5000 rpm not sound well? The machine is fine, but the CPU fan speed is too high, if you can't stand it, it is recommended to replace the CPU fan.

What does it mean to hold down? Don't let the fan turn? High speed is not necessarily bad, now the weather is getting hotter and hotter, ask more about your fan is original or rear-equipped, the noise of the original is generally relatively large, don't worry too much, if you can't stand the noise, replace the fan!

TT of around 100, overclocking three, and Cooler Master can all be considered!

This doesn't mean much.

Computer cooling and fan sound have nothing to do with each other.

Generally, if the fan is not installed, it will be very loud.

It's okay. Normal.

It's the same for every computer.

It is estimated that it is installed with a counterfeit fan, or the quality is not up to par.

You can try unplugging the fans of the CPU, graphics card, and motherboard to determine which one is louder.

If it's a power supply, it can only be said that it's too unfortunate, and if it's the other three, it doesn't cost much to replace it.

Top with professional lubricants.

There is also the possibility that the screws are loose.

Solve it directly with the boss who sells your computer, and he will help you

Reasons: 1. The use time is too long, the coil of the fan is aging, and there is a lack of oil.

2. Due to improper use, the central shaft is bent due to impact or vibration.

3. The position of the fan is offset due to excessive dust accumulation or loose fixing screws.

4. Power supply problem.

Solution:1Usually, there is no fixed speed of the computer fan.

It is caused by too many programs running on the computer, which may cause the cup, graphics card to heat up, etc. At this time, the fan will accelerate by itself, and the sound may be a little louder, but it is not very loud, which is considered normal.

2.Restart your computer without opening any programs and see if it is loud? If it's not big, you can use Master Lu to test it. There is a special testing tool to detect the performance of the computer. In the meantime, you can take your time and take a look.

3.If you don't know very well yourself, and the computer is still under warranty, it is recommended to send it to the after-sales service in time to check it. Clear your doubts!
