What does a dying laptop fan sound like?
If your laptop fan is loud, screeching, or making a grinding noise, it tends to be one of two things: Your device is overheating, or something inside it—like the fan—is broken. Extra fan noise is often a fact of life for many people who use high-powered laptops, especially gaming laptops. If it bothers you, consider using a pair of headphones to block out fan noise while working or gaming.
What is the lifespan of a laptop fan?
The official answer from the fan manufacturers is “between 30,000 and 50,000 hours” before fan replacement – which equates to between 3 and 5 years of continuous use. However, these statistics come with a lot of caveats regarding the operational conditions under which the laptop fan is operating. An average laptop can last four to five years, but the battery is usually the first to have issues. Unlike desktops, laptops have smaller parts that wear out quicker and are harder to replace. You can extend a laptop’s lifespan by monitoring its performance and upgrading parts when possible.
