You might also experience problems while starting up your computer, such as a black startup screen or an endless series of reboots. That’s why your computer crashes and gives you the notorious blue screen of death. When your PC’s internal temperatures get too high, your CPU will shut itself down to avoid permanent damage. Your CPU will self-regulate its performance to try and lower heat output, meaning that you’ll see a noticeable drop in speed and performance. If your fans can’t sufficiently reduce the heat levels inside your computer, you may start to experience a range of issues. A computer fan’s job is to keep your computer cool, and excessive fan noise means they’re working harder than they normally need to. Loud computer fans and loud laptop fans can indicate problems, especially if the noise persists for a long period of time. A computer fan making noise out of nowhere can indicate a high CPU usage issue. If there’s a program eating up way more than its fair share of your CPU’s resources, that can easily cause your computer to heat up fast. Sometimes, it’s not a fan problem at all. There might also be something wrong with the firmware for the hardware component running the wonky fan. Desktop and laptop fans that are running loud might be loose. Moving parts wear down over time and eventually break. Desktop PCs also need access to cool air. The word “laptop” is misleading - when you place it on your actual lap, your legs both transmit heat to your laptop and also prevent cool air from cycling in to cool it down. Dust and other debris are a common cause of noisy computer fans. As dust collects on your computer fans, they no longer work effectively. Dust builds up inside your computer, especially if you’ve got a bulky desktop PC.
Your computer fan might be running in overdrive for a few reasons: But if you’re experiencing lots of desktop or laptop fan noise under normal circumstances, read on to see what the problem might be. So long as they calm down when you’re done, this isn’t necessarily something to worry about. When putting your computer through intensive tasks - such as while playing online video games, editing large multimedia files, or performing a CPU stress test - it’s normal to have loud computer fans. To keep heat levels down, the fans inside your computer start spinning to push the hot air out and cool down your PC. And the sensitive electrical components inside your PC are vulnerable to high temperatures.
