Why is my desktop fan so loud? A loud desktop fan can be very annoying if you are trying to listen to some music. It can also get in the way if you are trying to be quiet. Fixing this problem is as simply as finding out why your desktop’s fan is so loud.
The most common reason is that you may have too much dust in your desktop fan. That will make the computer overheat. The desktop computer sensors will detect this rise in heat. In turn, it will tell the fans to blows as hard as they can to keep the computer cool. You will have to open up the computer to get rid of this problem. You can easily get this done with a Phillips head screwdriver.
If you have a new desktop computer then you won’t have to worry about using the screwdriver to open the desktop. Most desktop have a lever in the back that allows it to come off without any tools. Some other new desktops have screws that are designed to be turn with the hand. If you have an older desktop then you may have to use the screwdriver to get the side off.
Once you have the side of the computer off then you can get down to business. In this case, you can possibly use a compressed air can to get the dust out of the CPU fan and metal heatsink. This should be the hottest part of the computer. If you feel the dust is trapped inside of the CPU fan then you will have to remove the CPU fan from the motherboard to manually clean it.
After you put everything back together, you should no longer have that problem with your desktop CPU fan. You computer should have better performance and it should also be a lot quieter. If you want to avoid this problem as much as you can then you can actually buy an aftermarket desktop CPU fan for better desktop cooling. This will extend the life of the desktop and reduce the amount of times you will have to clean out your desktop CPU fan.
