Quiet operation is something that you may want to have in a homebuilt computer. When running processes, most of your internal computer components will always generate some noise because they need to move. Some good examples of “noisy” computer components are your hard drive and your computer fans.
Most of the noise generated by an average computer is almost always due to the internal computer fans. The blades of the fans spin at a fast rate and this movement creates sound. The hotter your computer runs, the harder your fan works. And the harder your fan works, the more noise it creates.
If you want to minimize the noise that the internal fans of your custom-made computer create, get a larger fan. A fan with a diameter of 120mm is quite good. Compared to smaller fans, larger fans spin slower. As such, they generate less noise.
Do not forget to take into account the size of your computer case when purchasing your internal fans. The fans need to fit inside the case together with your other internal computer components. You will have a very difficult time assembling your own computer if several components get in the way of each other.
When building your own computer, the internal computer fans need to be arranged in such a way that the flow of air is maximized. Air has to be coaxed inside the case, guided through the hot computer components, and escorted at the back of the computer case. You will need one fan to draw in cool outside air and another fan to usher out hot inside air. The other remaining fans should help guide the air through your internal computer components.
And when you are connecting the fans to your motherboard, make sure you attach them properly. You do not want your fan to expel air when it should be drawing air inside your case instead.
