44 // How to Build a Computer This section of the building process will be brief and cover adding fans to your case. The purpose of this is to generate good airflow, and help reduce dust build up inside your computer. Case fans also help keep the inside temperature of your system down by cooling excess heat.

Case fans

All computers need more than one fan inside, especially since the parts in your computer are putting off a large amount of heat, and require a lot of energy to power. Normally you will see on average five fans that are mounted inside the case, and some cases come with one or more fans pre-installed. You will want to purchase some extra fans, but make sure that the size fan you buy fits your case. The most common size fan is 120mm, but consult the make and model of your case for the appropriate size. Now, lets start installing your case fans.

Case locations

These are the main areas where you will be putting your fans. Most often you will put two or three fans in the top and front of the case, and one or two at the back. How many fans you will need in these areas are based on the size, make, and model of your case.

Let’s install the case fan!

Installing the fan is pretty easy, and once you install one all of the others are done the same way. Each fan has four holes that will match up to areas on the case to be screwed in. The screws you will need are included with the fan.

The front and back fans need to be positioned so that they are pulling in the outside air to blow inside of your case. The top fans will be doing the opposite, and should be placed to pull in the air from inside the case to be blown outside. Having your fans this way will help keep the inside cool, circulate airflow, and push some dust out.
