Do laptop keyboard covers cause overheating?


Are laptop keyboard covers safe?


Laptops have become an essential part of our lives, providing us with convenience and portability. To safeguard these valuable devices, many users opt for laptop keyboard covers. However, an ongoing debate has raised concerns about whether these covers could potentially cause overheating. In this article, we aim to delve into this topic and provide a comprehensive analysis of the effects of laptop keyboard covers on device temperature.

The Functionality of Laptop Keyboard Covers

Laptop keyboard covers are designed to protect the keyboard from spills, dust, and other potential hazards. These covers are typically made of silicone or similar materials that are both flexible and durable. They fit snugly over the keyboard, creating a protective barrier that prevents liquid damage and dust particles from entering the device. As a result, many laptop users consider investing in these covers as a precautionary measure to extend the lifespan of their devices.

However, despite their protective benefits, concerns have been raised regarding the impact of laptop keyboard covers on device temperature. Let's explore both sides of the debate to gain a better understanding of the potential risks and benefits.

The Argument Against Keyboard Covers

Proponents of the idea that laptop keyboard covers cause overheating argue that these accessories can interfere with the laptop's natural cooling mechanism. Laptops are designed with tiny ventilation openings to allow heat to escape, and any obstruction to this process can lead to elevated temperatures.

When a keyboard cover is placed over the laptop, particularly those made of thicker materials, this can impede the flow of air and trap heat within the device. Over time, the accumulation of heat can negatively impact performance, shorten the lifespan of internal components, and cause thermal throttling, where the laptop automatically slows down to prevent overheating.

Moreover, opponents of laptop keyboard covers argue that the positioning of the cover itself may exacerbate the issue. Due to the snug fit required for a proper shield, the cover can press down on the keys, potentially restricting the space beneath each keycap. Consequently, the airflow required to cool the laptop's internals may be significantly limited, leading to a rise in temperatures.

The Argument For Keyboard Covers

On the other hand, advocates for laptop keyboard covers contend that these accessories do not cause significant overheating issues. They argue that laptop manufacturers are well aware of the potential risks associated with keyboard covers and design their devices accordingly to dissipate heat effectively.

According to this perspective, the ventilation openings present in laptops are strategically placed to ensure that critical areas, such as the processor and graphics card, receive sufficient airflow. The addition of a keyboard cover may restrict some airflow, but it is generally believed to be minimal and within the operational parameters defined by the manufacturer.

Furthermore, proponents argue that the accumulation of dust and debris within the keyboard can pose more substantial dangers to a laptop's lifespan and performance. Keyboard covers effectively prevent such particles from entering the device, thus ensuring that the internals remain clean and free from potential damage caused by contamination.

Taking a Balanced Approach

While opinions on the effects of laptop keyboard covers on overheating may differ, it is crucial to consider a balanced approach when forming our own judgment. Understanding the potential risks and benefits can help users make informed decisions regarding the usage of keyboard covers for their laptops.

It is worth noting that the impact of keyboard covers on temperature largely depends on various factors. These include the type and material of the cover, the laptop's design and cooling capabilities, and the user's environment and laptop usage patterns.

Recommendations for Safe Usage

To mitigate potential risks associated with laptop keyboard covers, here are some recommendations for safe usage:

1. Opt for thinner keyboard covers:

Thicker covers obstruct airflow to a greater extent. By choosing thinner cover options, you allow for better ventilation and heat dissipation.

2. Keep an eye on device temperature:

Regularly monitor your laptop's temperature to ensure it remains within acceptable ranges. Various software applications can provide real-time temperature readings for your laptop's internal components.

3. Choose quality materials:

When purchasing a keyboard cover, prioritize quality materials that do not retain heat. Consider options made from lightweight and breathable materials to minimize any potential impact on device temperature.

4. Maintain a clean environment:

While keyboard covers protect against spills and dust, it is still essential to maintain a clean environment. Regularly clean and remove dust from both the cover and the laptop's ventilation openings to maximize cooling efficiency.


In conclusion, whether laptop keyboard covers cause overheating remains a subject of debate. While some argue that these accessories may restrict airflow and contribute to increased internal temperatures, others emphasize the importance of protecting laptops against dust and liquid damage. Ultimately, the decision to use a keyboard cover should be based on individual preferences, laptop design, and environmental conditions.

To ensure the safe usage of laptop keyboard covers, users should consider opting for thinner covers, monitor device temperature, choose quality materials, and maintain a clean environment. By adhering to these recommendations, users can strike a balance between protecting their laptops and mitigating any potential risks associated with overheating. Remember, each laptop is different, and understanding your device's specific cooling requirements is vital for optimal performance and longevity. Stay informed and make wise choices to enjoy a well-protected and efficiently functioning laptop.
