What is coil whine?

Coil whine is a high-pitched noise that can be produced by electromagnetic coils or transformers in electronic devices, such as computer components, power supplies, and graphics cards. It is typically not a sign of a faulty or failing component, but rather a normal byproduct of the electrical currents moving through the device.

The noise is often described as a buzzing, whining, or squealing sound, and can vary in intensity depending on the workload of the device. Coil whine is usually most noticeable when a component is under heavy load, such as during gaming or other demanding tasks.

While coil whine is generally harmless and does not affect the overall performance or lifespan of the device, it can be annoying to some users, especially in quiet environments. Some ways to reduce or eliminate coil whine include adjusting power settings, using high-quality power supplies, or installing sound-dampening materials.

Overall, coil whine is a common occurrence in electronic devices and is not usually a cause for concern, but it can be a nuisance for those sensitive to high-pitched sounds.
