Isn’t it annoying when you have a Laptop and all you can hear is the fan revving or making a super loud noise? There are a few different ways as to why your computer fan is so loud and, in this article, we are going to explain the most common reasons and the best ways to resolve the loud-sounding fan.
What does the computer fan do?
It’s important to understand the reason for the fan. The fan is linked to the heatsink / CPU which allows your computer to process all the information it’s running. The fan allows the hot air to flow out of the computer without it getting too hot and overheating. The location will change per a different computer, if it’s a laptop you’ll only have 1 fan but if you have a desktop you could have several fans. This leads to the next paragraph.
So if you have a desktop computer you could have more than 3 fans in one computer. Having multiple fans could mean that it sounds louder than it is but another issue with this is that you could have different manufactured fans. Each type of fan will have different volumes, for example, a bequiet fan will generally be a lot quieter than a standard fan in a computer case. Of course, if you have a laptop this may not apply.
One reason your fan could be loud is due to it being broken, it’s a very common thing with computer fans. There are a few ways you can resolve this, either take your computer apart and try to see if anything’s wedged, if not replace the unit. You could also try to repair the pivot if you’re tech-savvy but we wouldn’t recommend it. The good news is that if you’re using a computer you can get a fan very easily on Amazon. If it’s a laptop you will have to get a specific one from eBay or contact your local IT professional to get the part and replace it for you.
The whole point of a computer fan is to cool the computer. The problem is, however, when either the cooling paste is old or the RPM of the fan is set too fast. On some computers, you can manually set the speed of your fan which will make it sound a lot louder! However, some computers will automatically increase the fan speed on a higher heat which will cause the fan to become loud again.
This is one of the most common reasons why your computer fan is so loud. With your computer or laptop being in your house all the time and no easy way to clean it the dust can gather easily causing the fan to work harder which in return causes it to sound loud. The best way to resolve this is to use a specialist computer cleaner or air can which can blow the dust-out, hopefully reducing the volume.
The majority of the time your computer fan runs loudly because either the fan has broken, the computer has gotten hot or it could just be the make of your computer fan. Either way the best way to get the problem resolved is to take it to an IT professional to get fixed. Hopefully the above guide will have answered the question of “why is my computer fan so loud?”
