Why is My PC Louder Than Normal?

There are a couple of reasons your PC might be louder than normal. One is overheating, or an insufficient amount of ventilation. Another is malware. While you don’t want to use your PC for malicious purposes, it’s important to be aware of the possibilities.

Excessive dust

If your computer is whirring loudly, the chances are you have excessive dust on its fan. Excess dust on your computer makes the fan work harder to keep your computer cool. Dust also increases the temperature of your computer, causing it to run hotter. To fix this problem, you need to clean the dust from your computer. This can be done by blowing the dust away from the fan grates.

To clean the fans, you can purchase compressed air (available from most electronics retailers). Depending on the model, you can also use a soft brush to remove dust from your computer. Avoid blowing compressed air directly into the fan because it can damage the fan.

Dust is another problem that affects fans on a desktop computer. It can clog the fans and prevent them from cooling. To prevent this problem, keep the computer on a flat surface.


There are a number of reasons that your PC may be overheating. You need to ensure that your PC’s fans are functional so that it can run at a safe temperature. If you have overclocked your PC, you should reset it to its factory settings. Also, you should remove any memory-hogging programs that may be running in the background.

Soft surfaces like carpets and soft furnishings may obstruct your laptop’s vents and prevent it from cooling down properly. Try to rest your laptop on a hard surface or raise it to allow more airflow to the components. In addition, dust can collect in the vents of your laptop and restrict air flow around the components. If your computer is running slowly or loudly, it may have dust blocking it.

Another common cause of noisy computer fans is overheating. It can be caused by a variety of factors, from intensive programs to malware on your computer. You should keep your CPU usage to less than 20 percent while the computer is idle. Also, make sure the fans are only turning on when you’re using intensive tasks.

Inadequate ventilation

If your PC is louder than normal, you may have an issue with improper ventilation. A lack of airflow can cause your processor to slow down. This problem may also be the result of a buildup of dust or poor PC storage. To check if the ventilation is working properly, shut down your PC and inspect its vents. If necessary, you can use compressed air to clean the vents and dust filters.

Inadequate ventilation can also cause your computer to overheat. Avoid placing your laptop in an enclosed area, and leave two to three inches of space on all sides of the laptop. Also, it is important to update your device drivers, since outdated drivers can cause your system to work harder than necessary, which will cause your computer to be louder.


A computer can become noisy when there is malware or an infection. These unwanted programs may take up large amounts of storage and other resources. They may also overwork the CPU and cause the fan to spin faster than usual. Using a malware removal tool can remove the infection and make your computer quieter.

Computer viruses come in many shapes and sizes, but they are all bad for your computer. They can cause your computer to run slowly or freeze. They also eat up a lot of CPU and system resources. The fan on your CPU will become louder and your computer will be hotter than normal.

If your CPU is using 100% of its resources, your computer is likely suffering from malware. If this is the case, try disabling Windows Superfetch service or using a performance optimizer to remove any unnecessary programs and files. Additionally, check the hard disk for errors by running CHKDSK on your system.
