Is it normal for a laptop fan to run constantly?
It is normal for laptop fans to run when you use them. They are designed to run when needed, which is true of most desktop computers. If you’re playing a game, watching a movie on your laptop, or doing something else that requires a lot of processing power, it will generate heat.
The CPU will be working harder than usual, and this will cause the fan to work harder too. This is normal; it just means your laptop needs more cooling than usual to continue running at its normal speed without overheating.
However, this is not normal if your laptop fan is running fast for no reason, and you can hear it from across the room. In most cases, if your computer is overheating, it will shut down automatically before any damage is done.
Sometimes, yourPC won’t turn on after overheating. If this happens, you will need to check for other issues with your computer, such asviruses or malware, that might be slowing things down or preventing proper cooling.
You may also run into another strange issue where yourfans turn on, but your PC doesn’t. Check out our detailed article on how to address this problem.
