Why Does Motherboard Make a High Pitched Noise?

Do you ever hear a high-pitched noise when your computer is on? You’re not alone. Many people hear it, and it’s caused by something called Motherboard Noise. But what is Motherboard Noise, and why does it make that sound? In this blog post, we’ll explain what Motherboard Noise is and Why Does Motherboard Make a High Pitched Noise? We’ll also give tips on how to reduce or eliminate the noise. Keep reading to learn more!

Why Does Motherboard Make a High Pitched Noise?

The high-pitched noise from your motherboard is electromagnetic interference (EMI). This interference can come from various sources, including power lines, electrical devices, and even other electronic components. The other main reason is some components or hardware attached to the motherboard. 

While EMI can be annoying, it’s not harmful to your motherboard or other electronic components. Most electronic devices are designed to operate in the presence of EMI. However, if the noise is particularly loud or bothersome, you can do a few things to reduce it.

One way to reduce the amount of EMI your motherboard is exposed to is to move it away from other electronic devices. Move the tower away from your monitor or other peripherals if you have a desktop computer. If you have a laptop,  keep it off metal surfaces and away from power cords and other electronic devices.

What Components On My Motherboard Making A High Pitched Noise?

While the high-pitched noise you’re hearing is coming from your motherboard, it’s not the motherboard itself making the noise. The noise is coming from one or more of the electronic components on the motherboard. These components include:

1. The CPU Fan:

CPU fans are the main reason for the CPU sound. The fans start running at their full pace whenever your CPU gets heated. It always makes a weird sound. It often happens when you play games or work on a CPU’s full potential. CPU fans always need to cool down the processor to be running at full speed. That is why they often produce whining sounds. Try to replace them. 

2. The GPU (Graphics Processing Unit)

The second thing that makes the high-pitched sound on your motherboard is the GPU. The reason behind this noise is the same as the CPU. The GPU also has a CPU beneath the fans. This processor indicated the high heat signals to fan controllers, and the fans started working in no time. This could be another reason for the high-pitched sound from the motherboard. 

3. The PSU (Power Supply Unit)

Sometimes you confuse the power supply fan sound with the motherboard sound. It is different. Motherboard components make acoustic noise. Sometimes they produce vibrating sounds. Just check the PSU separately if possible to identify the sound. You have to remove the power supply from the mainboard and jump-start it. 

Still confused? Why does my power supply make a high-pitched noise? It is because of two main factors. One is the power supply fan and the second is the old transformer. The transformer generates and refluxes the current. Old transformers do make weird sounds while current passes through them. Try to replace the PSU. 

4. The HDD (Hard Disk Drive)

Hard drives are always in processing while working on your PC or laptop. It has heads and readers in it. Why do they make such annoying noise? The reason could be the age of your hard drive. Old hard drives often make high pitch sounds while writing data. The movement of the head inside the hard drive also causes weird sounds. 

5. Inductors

Inductors are copper-made components. They are coiled around a magnetic circle. These are used to store energy in the form of a magnetic field. When the current flows through this component, it produces a rattling sound. It happens only in the old inductors. If you face such an issue, contact any computer repairing service. 

6. Faulty Capacitors

Capacitors also store energy in the form of current. They have a thin foil-like film wrapped with paper inside them. If your capacitors are not working properly or that film is damaged, it can cause a high-pitched noise from your motherboard. To check if your capacitors are faulty, you can use a multimeter to check for continuity.

7. Overheating

Overheating can be caused by many factors such as dust, high ambient temperature, and faulty cooling system. Recently mining on computers has also tremendously increased. This affects the CPU temperature. It is also a reason for over-hating. It also depends on where you have placed your computer due to overheating inside the computer case. If your motherboard is overheating, it will produce a high-pitched noise.

8. Loose Connections

If there are loose connections between your motherboard components, it can also cause a high-pitched noise. This sound is produced due to an interrupted current or short circuit. To fix this, you can try to reseat the connections or replace the affected parts completely. Try to contact a professional for this job.

9. BIOS Settings

The BIOS settings can also cause a high-pitched noise from your motherboard. If the BIOS settings are not configured properly, it can cause the fans to spin faster, which will produce a high-pitched noise. Or if you have tried to overclock your processor, this may also be the reason. To fix this, you can try to reset the BIOS settings to default.

10. Physical Damage

Physical damage to the motherboard can also cause a high-pitched noise. It may damage different components like capacitors, inductors, resistors, etc. Due to malfunctioning, they will make weird noises. If there is any physical damage, you will need to replace the damaged parts.

Is It Normal To Hear High-Frequency Noise From Motherboard?

It is not normal if the noise is very high-pitched and high frequency. There are some noises when you turn on your motherboard, But they are in a limited range. It may indicate that something is wrong with your motherboard or any hardware. It may also be the symptom that something will happen with any of the motherboard’s components.

So if you hear a high-frequency whining sound, try to resolve it. To know some factors in identifying the sound, keep reading to learn more about it.  

What Is Coil Whine? Is It Bad For Your Motherboard?

Coil whine is a high-pitched sound that comes from the electrical coils on your motherboard. It’s caused by electrical interference and can damage your computer if left unchecked. There are various coils in your computer system that can make such sounds.
