Turning Subway menu-board computers into gaming machines: a challenge between passive performance and modern gaming ⚙️🎮
📝 Article summary
In an exceptional technical experiment, an ambitious gamer turned the silent fanless PCs used in Subway menu boards into gaming computers, taking advantage of low-power Intel Core i3 processors that run without a cooling fan. These devices face a challenge in delivering acceptable performance for modern games, achieving frame rates limited to 15 fps in GTA V and 25 fps in Minecraft. The article examines how simple desktop computers can be adapted and their entertainment experience enhanced, with a focus on the limits of passive cooling technologies and software options to achieve the best possible benefit.
💻 Technical background: about fanless PCs in electronic menu-display systems
Many fast-food restaurants such as Subway use small, hidden computers that rely on the silent fanless PCs design to ensure quiet, long-lasting operation. These devices often depend on low-power Intel Core i3 processors to run menu display systems and ordering software.
These computers are characterized by:
- Small size and a neat, unobtrusive appearance.
- Low power consumption.
- No cooling fan (Silent Operation).
- Ability to run light, stable tasks.
However, these advantages come at the expense of the high performance associated with modern games that require strong processing and graphics power.
🤔 Why is the unique experience of turning these devices into gaming PCs interesting?
The experiment aims to test the limits of the technical capabilities of devices not originally intended for gaming, and to attempt to deliver an acceptable gaming experience using a passively cooled Intel Core i3 processor.
The results show:
- A modest ability to run GTA V at 15 frames per second (fps), which is within the bounds of very basic play.
- A better rate in Minecraft reaching 25 fps, due to the game’s less demanding graphical nature.
Challenges of passive cooling in gaming performance
Fanless devices rely on passive cooling, which severely limits processor clock speed and restricts sustained high performance, especially in gaming environments that require graphical endurance and intensive computing.
🧠 Technical challenges in using fanless processors for a usable gaming experience
Thermal performance and clock-speed constraints
The Intel Core i3 processors used in these devices are low-power and are often designed to operate within strict thermal limits.
- Fanless operation prevents higher clock speeds or allows them only for short periods.
- Temperatures reach levels that make comfort and sustained performance impossible with demanding games.
Integrated graphics processor (Integrated GPU)
These computers rely on the integrated graphics processor inside the central processor (Integrated Graphics), such as Intel UHD Graphics, which does not support advanced technologies that ensure high-quality graphics and performance for demanding games.
- This affects frame rates and the smoothness of game motion.
- It does not allow graphics to be rendered at high intensity, which requires adjusting resolution and graphics quality.
Memory and storage constraints
Random-access memory (RAM) and storage are important components in how games respond to complex graphical elements. Subway menu-board devices often come with limited memory modules compared with traditional gaming PCs.
- Negative impact on loading resources such as maps and open environments in GTA V.
- The need for compatible driver updates for the operating system used (usually Windows or Linux).
Why is this development important?
Developing such experiments reflects the ordinary user’s ability to test the limits of low-capability devices and understand the relationship between computer design, power consumption, and gaming performance.

Software tweaks and supporting settings
The gaming experience on these devices can be improved through several factors:
- Reducing resolution to lower levels such as 720p or even 480p.
- Lowering graphics quality to the minimum.
- Using lightweight operating systems and updating drivers regularly.
- Closing unnecessary background services to free processor and memory resources.
- Using software to control the device’s temperature and regulate processor consumption.
Using fast storage and expanded memory
When possible, using SSD storage and a larger RAM capacity helps reduce loading times and improve responsiveness.
- The original devices may be limited to restricted RAM, which constrains performance.
- Upgrading these components is sometimes possible depending on the device design.
Leveraging cloud storage networks and cloud gaming ☁️
Cloud gaming services are an attractive option for those who have thermally weak computers.
- Devices can connect to cloud services that host the game on powerful servers.
- The fanless device then becomes an access point with low operating load and better results.
Technology takeaway
Low-power devices like Subway menu-board computers can be turned into limited gaming units, but doing so requires technical modifications and patient endurance in the face of thermal constraints.
🔥🔐 The importance of heat management and its effect on device lifespan and gaming performance
Heat is a major enemy of devices that run continuously and heavily, especially those that do not rely on a cooling fan.
- High temperatures reduce the lifespan of electronic components.
- They cause stuttering and delays in games (Stuttering).
- Driver updates will not help without proper thermal controls.
Accordingly, heat management is essential to improving performance and preserving the device.
Passive cooling between advantages and limitations
| Advantages | Limitations |
|---|---|
| Complete operating silence | Limited thermal performance |
| No mechanical fan | Weak performance in advanced games |
| High reliability due to fewer moving parts | High temperatures under intensive use |
What is changing in the world of technology?
New cooling technologies and energy-saving processors offer hope for developing higher-capacity fanless devices that can support reasonably playable games in the future.
🎯 The future of gaming on low-power devices intended for office use
With the development of CPU and GPU technologies, especially with the entry of AI artificial intelligence into improving graphics and performance, we may see an increase in the ability of small or silent devices to handle games.
- Improving cooling technologies such as passive liquid cooling or new materials.
- Using artificial intelligence to improve frame rates and graphics through AI-based upscaling.
- Expanding caching capabilities and processing techniques to reduce the burden on the processor.
Cloud gaming models also remain a strategic option for those who cannot upgrade their devices.
Conclusion
The experiment carried out by the ambitious gamer in turning silent Subway menu-board devices into gaming platforms is evidence of the possibility of exploring new dimensions for low-power, low-consumption hardware. Despite the thermal and performance constraints imposed by passive cooling, software adjustments and technical solutions open a window for improving the user experience.
At the same time, the role of innovations in processors, cooling, and artificial intelligence stands out in pushing performance boundaries, making them suitable for both daily and entertainment use. Future solutions may integrate these technologies to bring smoother gaming to smaller, lower-power devices, giving gaming enthusiasts from different backgrounds the chance to express their technical creativity and personal experiences.
Important technical point:
Even the simplest devices can be harnessed to achieve new technical experiences, and passion and knowledge are the keys to true innovation.
