Reduce computer fan noise

What to do with a loud computer fan?


If you want to quiet down your computer fan, the only solution is often to change the cooler’s settings in your device’s BIOS system or additional software. Your fan could also be affected by dust buildup. In this case only a cleaning of the laptop’s interior can help. We tell you how to quiet down your computer.

Computer fans and power supply coolers are essentially components that help prevent your computer or laptop from overheating. How cooling your laptop or computer works best is something you can read in our advisory. A computer is equipped with several coolers that are activated at a certain temperature and serve to cool the case, the CPU and the power supply. Warm air is thereby transported outside and away from the hardware components. If the computer case’s insulation is leaking the computer fan or power supply cooler will produce a displeasing noise. Laptops are also equipped with coolers that prevent the device’s components from overheating. But how can you quiet down your computer or laptop cooler?

Quiet down computer fan with BIOS

The control of the coolers is located in the computer’s or laptop’s BIOS system. The BIOS is responsible for starting the system and can be accessed with a key combination during boot up. A laptop cooler can be noticeably loud due to its placement directly in front of someone, placed on a table or on your lap. You can access the laptop cooler’s settings with the BIOS setting for H/W, meaning hardware and monitor. Here you can set the temperature at which the cooler is activated. But be careful: If you choose to manually change the settings of the cooler’s activation you have to make sure that none of your computer’s hardware components are damaged in the process. You should refrain from turning the cooler off completely. If you turn the computer cooler off completely, hardware such as the graphics board or CPU could quickly take serious damage. Setting the computer cooler manually is always done at your own risk. In case you are not sure how to quiet down your computer, you should best visit a TrustATec partner near you.

Turn down the noise of laptop coolers with software

If you don’t want to change the BIOS settings you can also choose to use Freeware SpeedFan under Windows. This free software can access the control of your computer or laptop cooler and adjust the fan’s speed. At the same time the computer’s or laptop’s hardware components are checked upon and detailed information for your system is listed. Why are some computer or laptop coolers activated very early on and start to produce undesirable noise? Manufacturers set the cooler activation temperature low, so that the computer’s hardware is always protected. In most cases you can manually change these temperatures. But before you do that you should have a look at the manufacturers recommended thermal load for components such as main board, graphics board and CPU to make sure that the hardware won’t be damaged.

Power supply cooler makes noises

When your power supply cooler or your computer fan starts to make weird noises, it could be due to defective hardware such as faulty computer or power supply coolers. In this case you should choose to get a professional repair for your device. Your laptop or computer could crash or show a blue screen as a result of a defective cooler or dust buildup in your fan. It is no use to try to quiet down the cooler through the computer settings, only an expert can offer a professional repair for your device.
