Why might a motherboard be installed on top of spacers?

Building a personal computer is an exciting challenge, but it can be not easy to navigate if you aren’t familiar with the many parts. The motherboard, the central hub of a computer, is an essential portion of the device. The motherboard is the nerve center of a computer, where all the parts connect and exchange data.

While installing a motherboard, one common question is why placing the board on top of spacers is necessary. The necessity of using spacers when installing a motherboard will be covered, and a list of the best spacers on the market as of 2023 will also be provided.

What Are Spacers?

Small metal or plastic screws are called spacers to elevate a motherboard from a computer case. If you’re using a spacer, be sure it matches the size of the screw holes on your motherboard. Spacers prevent the motherboard from contacting the case, which could cause a short.

Why might a motherboard be installed on top of spacers?

For several reasons, putting a motherboard on top of some spacers might be done.

1. To prevent a short circuit

It was previously indicated that using spacers was necessary to avoid a short circuit caused by the motherboard’s direct contact with the metal case. Spacers must be used during installation to prevent the motherboard from coming into touch with the patient.

2. To improve airflow

When the motherboard is installed on top of spacers, a gap is created between the motherboard and the chassis, allowing for improved airflow. The motherboard and other components may benefit from being kept at a more constant temperature. As a result, extending their useful lives and enhance their performance.

3. To accommodate more significant components

If the motherboard is mounted on the case without any space between them, some features, including graphics cards, may not fit. Using spacers during motherboard installation makes room for more significant components and prevents them from interfering with other system parts.

4. To reduce vibration

Vibrations and other components from moving parts like hard drives and fans can be communicated to the case. Placing spacers under the motherboard during assembly can assist in dampening vibrations, which can boost performance and prolong the life of the parts.

How to Install Spacers and a Motherboard?

There should be no harm to the motherboard or other components if the spacers and motherboard are installed correctly. Below is the procedure:

  • The first step is to find the motherboard’s screw holes. Many screw holes can be seen around the board’s perimeter on most motherboards.
  • Second, position the spacers so that the case’s screw holes are aligned with them. The spacers need to go underneath the motherboard screw holes.
  • Insert the spacers into the casing using the included screws.
  • Position the motherboard’s screw holes in the spacers, then gently lower the motherboard onto them.
  • Use the included screws to secure the motherboard to the spacers. If you overtighten the screws, you risk breaking the motherboard.

How Important Are Motherboard Standoffs?

Motherboard standoffs are required; that much is true. To keep the motherboard from touching the metal of the computer case, they raise it to the correct height and insulate it from the metal. Without standoffs, the motherboard could be damaged by electrical shorts and other issues, rendering the computer useless. Standoffs should be used wherever possible while installing a motherboard to ensure safety and performance.

How Many Motherboard Standoffs Do You Need?

The size, shape, and layout of your motherboard’s mounting holes will determine how many standoffs you’ll need. While smaller form factor motherboards may have fewer mounting holes, standard ATX motherboards typically have 9 mounting holes that require deadlocks. It’s crucial to use the right amount of standoffs in the right spots to keep the motherboard from touching the case and from damaging it. For information on how many and where on your motherboard standoffs should be installed, consult the user manual or manufacturer’s website.

Do Standoffs Come With the Motherboard or the Case?

The motherboard or the casing may supply the standoffs for the motherboard. Some cases already have the necessary standoffs fitted for motherboards with a standard form factor, while others may need more added. Standoffs are sometimes included with or pre-installed on motherboards. To determine if standoffs are included and if more needs to be ordered, it’s best to consult the manuals for both the case and the motherboard.

What are motherboard spacers, and why are they used?

Little plastic or metal bits called “motherboard spacers” are placed between the motherboard and the metal surface of the computer casing to keep the motherboard at a slight angle. When the motherboard is kept from touching the case, it reduces the risk of electrical shorts and other issues.

Can a motherboard be installed without spacers?

While it is possible to install a motherboard without using spacers, doing so is not without risk. Without separators, the motherboard could potentially short out against the metal case, among other issues. If you want to keep your motherboard safe and sound, insulating it using spacers is necessary.

How do I know if my motherboard needs spacers?

If you want your motherboard to stay safe and sound away from the metal case, you’ll need spacers. Certain motherboards, however, may already have spacers fitted or feature integrated standoffs, eliminating the need for additional spacers. Find out if spacers are required by consulting the motherboard’s manual or the maker’s website.

What happens if I don’t install spacers when installing a motherboard?

Spacers should be used to prevent a motherboard from touching the metal case. This can lead to fires, fried components, and an utterly unworkable computer.

Can I reuse motherboard spacers when upgrading my computer?

Removal of the motherboard during a computer upgrade typically does not necessitate replacement of the spacers, provided they are in excellent shape. If the spacers on your motherboard are old or broken, you should get new ones to guarantee that your motherboard stays insulated and safe.


Spacers are used during installation to keep the motherboard from shorting out against the metal of the chassis. This protects the motherboard and other internal components from electrical shorts.

By separating the motherboard from the case with spacers, which also serve as insulation, the motherboard may be safely installed. To prevent the motherboard from overheating, employing spacers helps increase the airflow around it.
