Understanding the Role of Fans in Mini PCs
Role of fans for cooling
Fans play a crucial role in maintaining the temperature of mini PCs by keeping the internal components cool. As mini PCs have limited space for heat dissipation, the compact size and high processing power generate a considerable amount of heat. Fans work by drawing cool air from the surroundings and expelling hot air away from the components, ensuring the system stays within acceptable temperature limits. Without fans, mini PCs would overheat, leading to reduced performance and potential damage to the internal hardware.
Why fan noise is produced
While fans are essential for cooling mini PCs, they can also create some unwanted side effects, most notably fan noise. The noise is primarily caused by the movement of air and the rotation of the fan blades. As air flows through the fan, it creates turbulence and friction, resulting in audible noise. The faster the fan rotates, the more noise it produces. Additionally, factors such as the quality of fan bearings and the load on the PC can also influence fan noise levels.
Factors Influencing Fan Noise in Mini PCs
Fan Size
The size of the fan is a significant factor influencing fan noise in mini PCs. Generally, larger fans tend to produce less noise compared to smaller ones. This is due to the fact that larger fans can move the same amount of air with less effort, resulting in reduced turbulence and noise. Mini PCs often utilize smaller fans due to space constraints, which can contribute to higher noise levels.
Rotation Speed
The rotation speed of the fan directly impacts the amount of noise it generates. Fan speeds are measured in revolutions per minute (RPM). Higher RPMs generally produce louder noise as the fan blades have to rotate faster to move a larger volume of air. While faster fan speeds can improve cooling performance, they can significantly increase fan noise. Some mini PCs allow users to adjust fan speed settings, enabling a balance between cooling efficiency and noise levels.
Quality of Fan Bearings
The quality of fan bearings is another crucial factor influencing fan noise. Bearings help reduce friction and ensure smooth rotation of the fan blades. Low-quality bearings may produce more noise due to increased friction and vibration. Mini PCs with fans equipped with high-quality bearings tend to operate more silently, providing a better user experience.
PC Load and Usage
The load on the mini PC and its usage patterns also impact fan noise. When the PC is under heavy load, such as during gaming or resource-intensive tasks, the components generate more heat, requiring the fan to work harder to dissipate it. This increased workload can result in higher fan speeds and consequently, louder noise. On the other hand, during idle or low-intensity usage, the fan operates at lower speeds and produces less noise.
How to Measure Fan Noise in Mini PCs
Use of Sound Meter Apps
One way to measure fan noise in mini PCs is by using sound meter apps that are available for smartphones and other devices. These apps utilize the built-in microphone to measure the sound levels in decibels (dB). By placing the device near the mini PC’s fan, users can get a rough estimate of the noise produced. While not as accurate as specialized noise measurement tools, sound meter apps can provide a general idea of fan noise levels.
Third-Party Noise Measurement Tools
For more precise measurements, third-party noise measurement tools can be used. These tools usually consist of a microphone connected to a dedicated noise level analyzer. The microphone is placed near the mini PC’s fan, and the analyzer displays the noise levels in dB. These tools offer more accurate readings and are often used by professionals to assess noise levels in various environments.

For example, a mini PC designed for basic office tasks may have quieter fans compared to a gaming-oriented mini PC.
Influencing Factors: Fan Size
Impact of Fan Size on Noise Levels
Fan size directly affects noise levels. Larger fans have a larger surface area, enabling them to move air more effectively while generating less noise. The increased blade size allows them to move the same amount of air with slower rotations, resulting in reduced turbulence and quieter operation. However, mini PCs have limited space, often requiring the use of smaller fans, which can contribute to increased noise levels.
Typical Fan Sizes in Mini PCs
Mini PCs commonly employ fans with sizes ranging from 40mm to 120mm. Smaller mini PCs tend to have fans around 40-60mm due to space constraints, resulting in potentially higher noise levels. Larger mini PCs or those designed for more demanding tasks may feature fans in the 80-120mm range, offering a better balance between cooling efficiency and noise reduction.
Influencing Factors: Rotation Speed
How Rotation Speed Impacts Noise Levels
Rotation speed plays a vital role in determining fan noise levels. Fans with higher rotation speeds generate more noise due to the increased turbulence and friction caused by the faster movement of air. On the other hand, slower rotation speeds result in reduced noise as the air moves more smoothly through the fan blades. However, slower rotation speeds may compromise cooling performance, especially in mini PCs with limited space for heat dissipation.
Typical Fan Speeds in Mini PCs
Mini PCs usually have fan speeds ranging from 1000 to 2500 RPM. Lower RPM fans tend to operate more silently, making them suitable for applications that demand quieter operation, such as media centers or office setups. Higher RPM fans are commonly found in gaming-oriented mini PCs, providing better cooling potential but generating more noise in the process.
Influencing Factors: Quality of Fan Bearings
Relevance of Quality Bearings to Noise
The quality of fan bearings significantly impacts fan noise. Well-manufactured, high-quality bearings reduce friction and vibration within the fan assembly, resulting in quieter operation. On the other hand, lower-quality bearings may produce more noise due to increased friction and potential defects. Mini PCs equipped with fans featuring high-quality bearings provide a quieter user experience, even during demanding tasks.
Types of Fan Bearings Used in Mini PCs
Mini PCs typically utilize three types of fan bearings: sleeve bearings, ball bearings, and fluid dynamic bearings (FDB). Sleeve bearings are the most common and economical option but tend to produce more noise over time due to wear and tear. Ball bearings provide better durability and lower noise levels but come at a higher cost. FDB bearings, often found in high-performance mini PCs, offer improved noise reduction and longevity compared to sleeve and ball bearings.
Influencing Factors: PC Load and Usage
The Effect of PC Load on Fan Pressure and Noise
Mini PCs experience varying levels of load depending on the applications being run. Higher PC load, such as gaming or resource-intensive tasks, places greater pressure on the components, generating more heat that needs to be dissipated. Consequently, the fan needs to spin faster to effectively cool the internal hardware, resulting in louder noise levels. During lighter workloads or idle periods, the fan can operate at lower speeds, reducing noise output.
