How is a motherboard backplate necessary for good CPU performance?

A backplate is a metallic piece used to protect the back of a graphics card. It can also balance the weight of the processor’s heatsink and prevent any damage to the Motherboard. Backplates may appear to serve just cosmetic functions at first glance. Still, they do more than making a graphics card look great. In this article, we will also discuss if a motherboard backplate is necessary or not.

What is a Backplate?

A backplate is a piece of hardware used to cover the back of a graphics card. It can be made of aluminum, glass, or stained steel. Though the Backplate is designed to improve the appearance of the graphics card, it may also be used to balance and stabilize the graphics card itself. Furthermore, depending on the material used, they can transfer heat. The Backplate itself acts as a cover that protects the graphics card from external influences.

A backplate provides support and stability to the graphics cards. Graphics cards are expansion cards that include an integrated graphics processor to boost image output performance by converting binary data into images. This does not function independently; in fact, the graphics card is only one of the components that caused a picture to emerge on a screen.

Can we use Motherboard without Backplate?

Nope, it is not necessary to install the Backplate, the computer will work absolutely fine without a backplate, but if your cooling system weighs more than .500 grams, It will prevent damage to the board from bending.

Purpose of Motherboard Backplate

Backplates are often constructed of aluminum. However, stainless steel or acrylic are also used on occasion. Some metals are well-known for aiding in heat dissipation in electronic components. Typical air-cooling systems employ metallic heatsinks composed of aluminum and fans to disperse heat. Even when backplates are constructed of aluminum, they only lower the temperature of the motherboards by -1 or -2 Celsius degrees. Therefore they do more distribution work than dissipation work. However, if a fan is put directly in front of the Backplate, actual heat dissipation occurs.

Rather than stainless steel, aluminum is frequently utilized in heatsinks. Because it transports heat 15 times quicker than stainless steel, pure aluminum has higher thermal conductivity (235 watts per kelvin per meter) than stainless steel (15 watts per kelvin per meter). Motherboard Backplates do not disperse heat on their own; hence they are mainly used as a show element rather than a cooling component. A backplate, on the other hand, can give support and stability to the Motherboard. 

When Motherboard is upgraded, the size of the Mobo may change, causing the Motherboard to exceed the surface that could previously be utilized on the CPU, requiring the usage of the Backplate. As a result, the Backplate stabilizes the graphics card and strengthens the motherboard and GPU structure.

Backplates can also serve as a passive heatsink by distributing the heat generated by the graphics card. The majority of backplates are composed of aluminum, which has a high heat conductivity.

Temperature control by Backplate

A backplate can reach incredibly high temperatures, even exceeding 60°C; nevertheless, this is not a cause for concern. Electronic components can now withstand high temperatures without deterioration. At the same time, backplates absorb the heat generated by the processor installed in motherboards and CPUs. As a result, backplates aid in the distribution of CPU heat.

Backplates are generally metallic component that covers the Motherboard; hence heat transmission is a possibility. The Backplate’s large area and metallic surface allow the motherboard processor to maintain a stable temperature and better “management” of the heat. As a result, the heat dissipation will be determined by the backplate material. A backplate, on the other hand, will never match the efficiency of a proper cooling system.

Does the motherboard backplate assist in good airflow?

The passive backplate function transfers heat to themselves without needing a fan, which is precisely what a backplate accomplishes. Backplates can act as a passive heatsink for good airflow, even if they weren’t designed for it.

Aluminum backplates are used, and this material is recognized for its heat conductivity. Backplates and passive heatsinks share more than just the material aluminum. Passive heatsinks have a vast surface area to transfer heat and are positioned directly over the item to be cooled. Passive heatsinks, on the other hand, feature a unique form that optimizes heat transfer and dissipation. Backplates have a flat design and only decrease the heat by -1 or -2 degrees Celsius, but genuine heatsinks reduce heat by twice as much. Backplates can assist in dispersing and minimizing the heat generated by CPUs. They can also act as passive heatsinks, although this is not their primary role.

Is the Retention bracket and Motherboard Backplate the same?

The retention bracket is the front of the motherboard bracket where you install your CPU—also referred to as the CPU Socket. The CPU is held in place by a unique lever. The Backplate is located on the other side of the Motherboard, on the backside. 

This plate has two purposes:

  • To put the cooler’s screws in place
  • To transport heat from the Motherboard’s opposite side to the cooler as well.

So, if the cooler you bought requires it, you’ll need the Backplate as well. The cooler includes the Backplate. It is usual for motherboards to have a backplate, which is subsequently used by the cooler. It’s also usual for the more remarkable to come with its Backplate, which you should utilize.

Because the sequence of operations varies significantly depending on the cooler, it’s better to stick to the instructions that came with it. However, you may install the CPU first. I wouldn’t put the Motherboard in the case until the CPU and cooler were installed on the Motherboard.

Do Graphic cards need a Backplate?

Backplates are beneficial but not essential products; they are branded as an accessory. They primarily “improve” the graphics card’s look. Backplates provide a lovely and durable cover for the graphics card. Still, they also provide other functions such as heat dispersion and stability. The robust surface of the backplates provides weight stability and sturdiness to the GPU frame. Furthermore, the backplates are constructed of aluminum; they are helpful for heat dispersion since their lengthy surface absorbs and resists high temperatures. Hence, if a fan is positioned directly in front of them, the backplates will aid in heat dissipation, effectively acting as a cooling device.

Furthermore, the Backplate has a cover protecting the graphics card’s back from external components such as liquids that might harm the GPU and kill it, but chances are meager.

Is the Backplate for the Graphic card as crucial as the Motherboard backplate?

Aside from its aesthetic value, backplates also serve to cover and protect the graphics cards. As a result, the GPU becomes more durable, and its structure becomes more robust.

Finally, the use of heat dissipation is only an added benefit of aluminum features. Because most backplates are composed of aluminum, the metal’s thermal conductivity allows it to operate as a passive heatsink in some cases; nonetheless.

Installing Motherboard Backplate

The best technique to install the Backplate is to push it in from the inside of the case. You’ll want the metal ring, but verify how the ports on your Motherboard are set out to ensure you’ve got it correctly. Once it’s in the proper direction, give it a little push, and it should click into place.

Now that you’ve fitted the Backplate, it’s time to measure your Motherboard. Turn your computer on its side so that the central cavity is facing up. Inside your case, there should be several pre-drilled holes in the rear. Take your Motherboard out of its anti-static bag and attempt to line them up with the holes on the Motherboard, ensuring sure it’s tight against the Backplate you’ve just installed. Please make a note of which holes you can see, and then place your Motherboard back inside its anti-static bag.


Backplates are great additions to a graphics card’s aesthetic, and they also offer some added functionality that is handy. The CPU performance is significantly affected by having a backplate and is essential for stability and airflow. Hope you enjoyed reading the article.
