The low Voltage and high Wattage means a strong Electric field( Amperage) is produced. GPU is the most important source of Coil Whine because it operates at low Voltage and high Wattage. In other cases, the noise is very less and less audible to our ears. The solenoid core of Inductors in some GPUs vibrate at high frequency and the Coil Whine Noise becomes prominent. If you increase the current flowing through the core then the electromagnetic force will be stronger and the whining noise or coil whine will be louder.Д¬oil Whining occurs in most GPUs but the frequency of vibration is different. This Force causes the Solenoid Core to vibrate at a certain frequency called Resonance Frequency that produces a buzzing or whining noise. This electromagnetic field produces an Electromagnetic Force. When a variable electric current passes through the Inductor or Solenoid core then an electromagnetic field is generated around the solenoid core.

If you use an external GPU with your laptop or desktop then the phenomenon is more prominent for some graphic cards. Coil Whine can be present in any electronic component that has transformers or Inductors.Д¬oil Whine is mainly observed in the Graphics Processing Unit(GPU) but it can also occur in the Motherboard, Power Supply Unit(PSU) and also your Hard Drive like the HDD or SSD.Д«oth Desktops and Laptops can produce Coil Whine and it pretty much depends on the laptop or desktop model you are using. This high pitched noise is unfortunately audible to the human ears and it will bother most people who donвЂ™t use headphones.

6 How To Fix Coil Whine In A Laptop and Desktop?Д¬oil Whine or Coil Noise is a high pitched sound that is produced when a variable electric current passes through an electromagnetic coil that produces a variable electromagnetic field causing it to vibrate at a certain frequency called Resonance Frequency.
