The fan speed on a laptop can determine how it operates consistently and reliably. You can slow it down or speed it up, based on the circumstances. For instance, slowing down the fan speed may be useful in reserving processes or during a prolonged slow time. Speeding it up is beneficial in keeping the laptop cool during ongoing use or high-traffic times. For the long term, find a happy medium for regular use, so you won't "psyche" out your computer by constantly adjusting the settings.
Click on the Start menu and select "Control Panel." Next, choose "Performance and Maintenance."
Select "Power Saver."
To slow the fan speed, locate the slider next to "CPU Processing Speed" and slide it down by moving across to the left. To speed up the fan, move the slider to the right.
Press "Apply" and then "OK," if prompted.
Keep track of how your laptop fan speed's settings affect the way the computer operates and make revised level adjustments, if needed.
Your laptop settings may have different level variations. Consult with the manufacturer's user manual for your particular model.
If the noise is the only thing making you want to decrease your laptop's fan speed, it may be trying to do you a favor by cooling the system down when needed. Like a car's radiator, the fan can click on to cool the car, and sometimes it's louder than normal when this happens. However, if the fan is constantly running to the point of annoyance, lower the setting.
