Introduction
When searching for a new graphics card that suits your needs, one of the many things to consider is the design and build of the card. Though it is significant to evaluate the memory, clock speeds, and power efficiency, the backplate of the card is also an essential factor to take into consideration. If you are unaware of what a backplate is, it is the metal panel covering the non-functional side of the graphics card. Nowadays, many graphics cards are designed with passive backplates to enhance the aesthetics of the card. However, do passive backplates affect your graphics card’s temperature and performance? Let’s delve deeper to understand it.
Backplates on Graphics Card
The primary purpose of backplates on graphics card is to act as a baseplate that provides a rigid structure and supports the card’s weight. It also serves as an additional heat dissipation structure that improves thermal performance by distributing the thermal load to a larger area. Additionally, backplates provide protection against electrostatic discharge and mechanical damage during installation or transportation.
These backplates can be split into two categories, passive and active. Active backplates include integrated cooling solutions, such as water blocks and heat sinks, that dissipate heat from the graphics card. However, passive backplates are designed to look better while providing minimal thermal benefits.
Passive Backplates
Passive backplates are unvented plates made of metal designed to improve the appearance of the graphics card. They are also less expensive to manufacture, adding an aesthetic advantage without driving up the price of the product. Many graphics card manufacturers add passive backplates to balance the overall look of the card and also use them to improve durability. These backplates do not have any direct way of cooling the graphics card, but they do offer several advantages when it comes to cooling.
Advantages of Passive Backplates on Graphics Card
Passive backplates reduce the amount of flex in the graphics card, which enhances its rigidity. This decreases the chances of the circuit board cracking and can extend the lifespan of your graphics card. Additionally, passive backplates assist with better weight distribution of the card and prevents any significant change in the shape of the card due to weight, heat, or pressure.
Passive backplates also protect the graphics card from external forces like accidental scratching and bashing that can occur during installation or transportation. This extra layer of protection can ensure that your graphics card remains in top-notch condition and lasts longer.
The area behind the GPU is essential when it comes to thermal management. Passive backplates help with distributing the thermal load from the GPU to a larger area, increasing the total surface area that can dissipate heat. This adds to the overall cooling performance of the graphics card, ultimately increasing efficiency while reducing the chances of overheating.
The primary benefit of passive backplates is that they protect your graphics card and make it look better, all while providing minor thermal benefits that can help with the card’s overall performance. It can be an economical way to have the benefits of a backplate without having to add extra cooling solutions.
Disadvantages of Passive Backplates on Graphics Card
While passive backplates do provide some benefits, they do come with some perceived drawbacks as they are less effective than active cooling solutions. Since passive backplates are designed to look better and provide little thermal management, they are incapable of actively cooling your graphics card.
Passive backplates prevent air from circulating around the GPU, which can initiate passive heat build-up, creating a feedback loop, leading to increased temperatures. This can usually happen if the graphics card runs a lot of high-resolution games, which puts extra pressure on the graphics card and the associated build-up of heat.
Passive backplates are less effective when attached to graphics cards with poor cooler designs. Typically, high-end graphics cards come with active backplates, and passive plates are meant for lower priced cards, meaning poor cooler designs. These cards generate more heat, and passive backplates may not be a good fit for such graphics cards.
Conclusion
Passive backplates on graphics cards can enhance the look of the card while offering minor cooling benefits. They are designed to distribute the thermal load over a larger area, prevent the circuit board from cracking or deformation, protect the card from scratches and bashing, and can extend the lifespan of your graphics card. Although passive backplates do not cool the graphics card actively, they can enhance the overall performance by adding an extra level of protection and defending against external forces.
When choosing a graphics card, it is essential to determine what you want in a card, be it active or passive cooling solutions. Though passive backplates won’t suffice for meeting high-end demands, it can still provide an effective and economical solution for consumers with less-thirsty graphics requirements. Therefore, it is safe to say that passive backplates have their advantages and disadvantages, but if used correctly, they can add value to the graphics card.
