I have this desktop which has a noisy fan and it is so annoying. I think CPU cooler fan was spinning nearly 4200 rpm. I just like to change it soon, but before I do so I would like to ask for your expert advice. Is it really the fan that is need to be changed or there are other parts that are causing this noise?
I don’t think so. Aside from the cooling fan, there are no other parts or components inside the CPU that will create noise. There are only four components in the CPU that uses a cooling fan. First, the power supply; second, the processor; third, the graphics accelerator or the video card; and fourth, the CPU tower itself.
Normally, the number one component in the CPU that produces an annoying noise is the cooling fan attached to the CPU. If you have a cooling fan attached to the CPU case, try disconnecting it from the power source and check if the noise is gone. If this is positive and the noise is really coming from the cooling fan of the CPU, replacing it with a new one would be a good idea.
If it is not the CPU fan that’s causing the noise, it is probably the cooling fan of the processor which is attached right above it on top of the heat sink. That’s the second possible source of noise that you might hear from the CPU. The cooling fan attached on the video card seldom causes annoying noise that can distract the user.
You can also adjust the setting of the cooling fan in the BIOS to make it a little slower but I’m not sure if it’ll do any good especially if the noise is so severe.
There are several causes for making a noisy fan of a desktop computer. When the motor of the fan becomes disable then makes noise. Spinning components of the fan may be recovered. One of the causes of noisy fan is heat. If your system is heated enough, then try to
• Clean Your Computer
• Get a New Heat sink (You may use water cooler)
• Invest in a Fan Controller
• Upgrade Your Fans
