When your laptop’s fans start running too loudly, there are a few steps you can take to try to fix the problem. The first step is to ensure that your laptop is adequately cooled and ventilated. Your laptop needs to be in an environment with adequate airflow, so make sure it is not placed on a bed or pillow where air can’t circulate freely.
Next, it may help to reduce the strain on your laptop’s processor by closing any unnecessary programs or processes. If you have been doing a lot of multitasking, this could be causing the fans to run more aggressively to cool the system.
If your laptop fan still seems to be running too loudly, even when it isn’t being used, then you may want to check for hidden processes that are running in the background. Some Windows users find that their laptops are running services like Google Update, Skype, Steam, and other auto-updates without their knowledge, which can put strain on the processor and increase fan noise. To check what is running in the background on a Windows system, hit the ‘Start’ button and type ‘msconfig’ and hit enter. Then, click the ‘startup’ tab and uncheck any processes you don’t need running.
If this doesn’t improve the situation, try cleaning the fans. This can be done easily with a can of compressed gas, which can be purchased at most electronics stores. Hold the can a few inches away from the fan grills and gently spray the gas in short bursts. This will help blow out all of the dust that has collected, and should reduce the noise from the fans.
You can also try downloading some cooling software to closely manage the temperature of your laptop. Software like Speccy can be used to monitor the temperatures in real time, and can help alert you when the CPU and fan speeds get too high. If the temperatures get too high, the fan speeds will automatically adjust to keep the system cool.
If none of these suggestions help, you may need to look into replacing the fan motors. This is a more advanced repair job and should only be done by a trained technician. Replacing the fan motors can be expensive, and in many cases, it may be more cost-effective to simply buy a new laptop.
Hopefully, one of these suggestions will help reduce the noise from your laptop’s fan. Keeping your laptop properly cooled and configured is a key part of maintaining its performance and longevity, so it is important to take steps to ensure that the fan isn’t running too loud.
