Warning: These PC Noises Signal Trouble Warning: These PC Noises Signal Trouble

Your PC’s typical hums and buzzes are usually nothing to worry about. But certain sounds can indicate serious problems that shouldn’t be ignored. A high-pitched whine, often called “coil whine,” is caused by the vibration of electrical components under stress.

This whine can point to subpar components that might fail prematurely. While harmless if it only occurs during intensive tasks like video rendering, a constant whine warrants a professional check or a warranty replacement.

Fan Noises: From Normal to Concerning

A gentle fan hum is a sign of a properly cooled system. However, a loud roar suggests dust buildup on the fan blades or worn-out bearings. Thorough cleaning or fan replacement can usually resolve this. A ticking sound, however, indicates that the fan blades are hitting an obstacle, likely a cable. This requires immediate attention, as a malfunctioning fan can lead to overheating, short circuits, or even fire if cables are damaged.
