For desktop PC make sure that there’s ample vacant space around it. In desktop adequate airflow in required in and around it so you need to place your PC outside of cupboard, if it’s inside it. Specially when summer season arrive, do not keep your laptop or desktop computer in closed room. If kept in closed room it will cause a rise in temperature. Unlike desktop, laptop has certain heat limit, and when laptop gets close to that limit it will start malfunction or get hang. If your laptop fan constantly running then it might be a wire loose issue. The processor fan is controlled by 4th wire where its yellow in color in most 4 pin fans unlike the 3 pin chassis fans, if the yellow one gets disconnected, it will cause laptop fan always on at it’s full 100% rpm.

Regularly Clean Your Computer Fan

If the above two steps are not helping you out in silencing the noisy computer fan. Then you need to open up your computer and start cleaning. Remember, dust is the major enemy of these machines, it causes overheating issues which may be why you have a noisy computer fan. We have already explained in our previous post of preventing computer from overheating the way to clean the dust out of your computer.

Before you start fixing your PC fans read some guides on ifixit. Clean CPU fan, graphics card fan and any other component having fan on it. Clean the power supply fan and computer case fan using Canned air. Canned air works great for CPU fans cleaning which will cost you around $5 USD at Amazon.

But what if all the above steps doesn’t yield any result or laptop fan not working, then you need to entirely remove CPU fan or any other PC fan and replace it with new fan. Because either the PC fan is broken or has stop working properly, that’s why above mentioned steps are not giving you any relief. You can buy the spare fan from nearby computer electronic store or from internet as well.

It’s also pertinent to mention here that there are many fan controller software on the internet. Some of these tools are Speedfan, SMcFanControl and macs fan control. These are free monitoring tools which also allows you to manually control the computer fan speed. But you must not use these tools unless you have advance knowledge about these apps.

For instance if your computer making noise and you slow down fan speed using Speedfan app before your computer cool itself down. It will cause overheat. To some extent these free software can also help you figuring out the noisy computer fan by increasing the fan speed. But i personally will not recommend you to play with these computer fan speed controller apps.
