What Is Coil Whine In Laptop And How To Fix It?

Electrical crackling or high-pitched noises may be experienced by users. Many of these issues will arise as a result of “coil whine,” which is inherent in the design of today’s high-power computer products. When current flows through electronic components like coils, they vibrate at specific frequencies, producing an audible tone that the human ear can detect. The symptoms may be more severe in high-end graphics chips. They may be more noticeable when used in a quiet environment. This is a software problem, not a hardware problem. The product emits a level of sound that is within acceptable acoustic parameters when in normal operation. The product’s performance is unaffected.

What Is Coil Whine?

Coil whine is a common sound in desktop and laptop PCs, especially those with older power supplies. You’ll almost certainly hear it unless you use headphones with your PC or your speakers are loud enough to drown out the sound of your GPU’s coil whine.

What Does Coil Whine Sound Like?

When you hear a coil whine, it doesn’t always have to be a “whine.”

Most of the time, a small rattling noise can be heard inside your computer’s components. This is due to the fact that this is the case.

Sensitive electronic components vibrate rapidly during a power surge, producing a noise known as coil whine.

Coil whine is either non-existent or significantly reduced at idle

Other laptops with coil whining, in addition to the Asus Rog and Zenbook Pro, include Dell’s XPS 13 and 15, as well as the Microsoft Surface Book 2 and Huawei’s Matebook X Pro.

In addition to the RTX 2080 and 2080 Super, the RTX 2070, RTX 2060, and GTX 1080 Ti all have well-documented coil whine. It can be found in AMD’s Radeon Vega 56 and Radeon VII graphics cards, among many others.

Why does Coil Whining occurs and has your laptop ever been Affected by Coil Whining?

Electromagnetic coils can be found in laptop and desktop GPUs, motherboards, power supplies, and hard drives. The cores of these coils are solenoid cores wrapped in wire.

Variable current flows through the core of the inductor or solenoid, creating an electromagnetic field around it. An electromagnetic field produces a magnetic force. The Resonance Frequency, which is the frequency at which the Solenoid Core vibrates, causes the buzzing or whining sound.

When the core current is increased, a louder whining noise or coil whine can be heard.

While most GPUs exhibit some coil whining, the frequency with which it occurs varies greatly. Coil Whine Noise is caused by the solenoid core of inductors vibrating at a high frequency in some GPUs. In other situations, the noise becomes increasingly imperceptible.

Is it possible to avoid the sound of “coil whining”?

Coil whine is difficult to eliminate because it results from a physical process that occurs during normal device operation. If the coil whine is coming from desktop components, a noise-isolating case is often the best solution. Connecting a set of headphones, on the other hand, may be the simplest option for many users. Lenovo makes every effort to reduce coil whine noise in our products, but it is impossible to completely eliminate it.

When playing at 240 frames per second or higher, you may need to limit yourself to 144 frames per second or less to reduce coil whine. When it comes to your FPS cap and refresh rate, you have some leeway depending on your monitor and GPU.

Even if your monitor is set to 144 Hz and your graphics card isn’t capable of it, a 120 FPS or lower FPS cap can prevent your card from occasionally reaching 144 FPS.

It’s debatable whether Coil Whining is a bad thing. Is It Bad for your laptop?

Coil Whine in a GPU is generally not harmful or dangerous. This will not cause any problems with your GPU. It will not be any different.

There’s a major issue with the high-pitched noise. When the noise level rises, most people become irritated. Wearing headphones will aid in noise reduction.

Coil whine can be dangerous due to the high ripple on a low-quality motherboard or power supply unit. If you have a power supply problem, it is possible that your laptop will shut down and not restart.

In extreme cases, power supplies can catch fire.

How To Fix Coil Whine On a Laptop Or Desktop Computer

Coil whine is impossible to completely eliminate from a laptop because lower-end components such as the GPU, Motherboard, PSU, and Hard Disk cannot be replaced.

Returning a laptop to the manufacturer or purchasing a new laptop can resolve coil whining.

The GPU’s Coil Whining noise, on the other hand, can be reduced or limited using the methods listed below.

VSync, FreeSync, and GSync are all options. As a result of the lower frame rate, your GPU will be less taxed.

Coil whine noise is reduced due to lower electromagnetic force and fewer vibrations caused by less load on the GPU.

While this may reduce coil whine, it will result in low frames per second (FPS) on games, causing lags and negatively impacting your performance.

use of abnormally low GPU voltages and clock speeds This will also reduce the strain on the graphics card and the whirring of the coils. Low frame rates per second will have an impact on game performance (FPS).

Turn off the GPU’s overclocking

It is possible to reduce coil whine by increasing the amount of power passing through your GPU.

If you’ve been experiencing coil whine after overclocking your graphics card, the first step should be to disable your overclock.

Even if this does not work, you can overclock your graphics card by fine-tuning the settings and lowering the voltage.

In most cases, coil whine caused by an overclocked GPU is best solved by simply not overclocking.

Use your GPU’s Eco or Low Power modes

Locate and click on the driver page for your specific graphics card manufacturer. When it comes to my graphics card, the Gigabyte G1 Gaming Nvidia GTX 1070, I can control it with a recently updated Utility program. This command will enable the Low Power or Eco Mode on your GPU.

The only way to fix coil whining is to replace the motherboard or power supply, not the motherboard or power supply itself. As a result, you’ll need to buy a new computer.

The various components of a desktop computer can be easily changed, allowing Coil Whine to be repaired. Most problems should be resolved by replacing the GPU and power supply. Avoid low-cost, low-quality components in favour of higher-cost, higher-quality ones.

By using an effective desktop case that blocks some of the noise, this noise can be reduced even further without compromising performance.

Final Verdict

High-fps games can cause the GPU to emit a high-frequency noise known as “coil whine.”

Coil whine can damage power supplies and motherboards, but it has no effect on laptop performance.

There is no way to completely eliminate laptop coil whine with VSync, FreeSync, or GSync, as well as GPU undervolting and overclocking.

To repair a desktop computer with coil whine, the internal components that cause it should be replaced.
