Can a 60×60×10mm Ultra-Thin Axial Fan Replace a 60×60×25mm Cooling Fan?

From Size Replacement to Performance Matching: Rethinking 60mm DC Cooling Fan Selection

In industrial equipment, medical testing equipment, automation systems, and other applications, 60mm fans have always been one of the most widely used cooling solutions.

As equipment continues to evolve toward:

• Smaller size;
• Slimmer designs;
• Higher integration;

the available installation space for cooling components is becoming increasingly limited.

This has led many engineers to consider a key question:

Can a 60×60×10mm ultra-thin axial fan replace a traditional 60×60×25mm axial cooling fan?

In some compact equipment designs, engineers also need to determine:

How should 60×60×10mm, 60×60×25mm, and 60×60×38mm fans be selected for different applications?

A common assumption is:

A thicker fan has a larger impeller, higher airflow, and therefore better cooling performance.

However, in real industrial cooling applications, fan thickness is not the only factor determining thermal performance.

The actual cooling capability depends on:

The matching relationship between the fan performance curve and the system impedance of the equipment.

Shenzhen JENTECH Electronics Co., Ltd. has extensive experience in industrial cooling applications, providing DC cooling fans, industrial fan selection support, and application testing services. Based on JENTECH cooling fan technologies and application experience, JENTECH helps customers select suitable thermal solutions for different operating conditions.

1. Why Are 60mm Fans Widely Used in Industrial Equipment?

60×60mm fans are widely used in industrial cooling applications because they provide:

• Compact structure;
• Easy installation;
• Wide performance range;
• Mature application experience.

60mm fans are commonly used in:

With the development of different equipment structures, 60mm fans have evolved into multiple thickness options.

Common specifications include:

2. 60×60×25mm: The Most Widely Used Industrial Standard Fan Size

In traditional industrial equipment designs:

60×60×25mm axial fans

have long been considered a standard cooling solution.

The main reasons include:

• High standardization;
• Mature mounting structure;
• Wide performance selection;
• Compatibility with many industrial applications.

Typical applications include:

• Industrial control cabinets;
• Communication equipment;
• Power modules;
• Automation control systems;
• Test equipment.

60×60×25mm fans usually provide a good balance between:

• Airflow;
• Static pressure;
• Noise;
• Service life.

For example, the JENTECH JC6025 series 60×60×25mm DC cooling fans provide multiple performance levels to meet different industrial cooling requirements.

3. 60×60×38mm: A Solution for High Airflow Resistance and High Heat Applications

Although 60×60×25mm fans are widely used, some high-load equipment requires stronger cooling capability.

Examples include systems with:

• High-density electronic components;
• Multi-layer PCB structures;
• Dust filters;
• Heat sinks;
• Narrow airflow channels.

These structures increase system airflow resistance.

In such applications:

60×60×38mm thick axial fans

become a suitable option.

Compared with 25mm fans, 38mm fans generally provide:

• Larger impeller space;
• Stronger airflow generation capability;
• Higher static pressure output.

They are suitable for:

• High-power supply equipment;
• Industrial control systems;
• Communication equipment;
• High heat-density electronic devices.

Under high resistance conditions, thicker fans can maintain a more stable operating point.

4. 60×60×10mm: A New Choice for Compact Equipment Design

With the rapid development of:

• Medical testing equipment;
• Smart devices;
• Portable industrial equipment;

equipment sizes continue to decrease.

However, the number of internal electronic components continues to increase.

This results in:

• Higher heat density;
• Less installation space;
• More difficult thermal design.

Therefore:

60×60×10mm ultra-thin fans

are becoming increasingly popular.

Compared with traditional 25mm fans:

Typical applications include:

• Medical testing equipment;
• Small analyzers;
• Precision measurement instruments;
• Compact industrial equipment.

However, an ultra-thin fan is not simply a smaller version of a traditional fan.

To maintain cooling performance, manufacturers optimize:

• Motor performance;
• Impeller design;
• Airflow structure.

---

5. Traditional Concept: Thicker Fan = Higher Airflow?

A common misunderstanding in cooling design is:

A 25mm or 38mm thick fan must always perform better than a 10mm thin fan.

This assumption only considers fan dimensions.

In actual equipment operation, cooling performance is affected by:

• Airflow resistance;
• Component blockage;
• Filter structures;
• Heat sink pressure loss.

Fans do not operate under free-air conditions after installation.

The maximum airflow listed in specifications only represents:

Performance without system resistance.

Once installed inside equipment:

Actual airflow changes according to system impedance.

---

6. Actual Cooling Performance Is Determined by System Impedance

Airflow-Pressure Curve Determines the Real Operating Condition

Professional industrial fan selection requires analysis of:

P-Q Performance Curve (Airflow-Static Pressure Curve)

The curve shows:

• Horizontal axis: airflow;
• Vertical axis: static pressure.

Every piece of equipment has its own:

System impedance curve

The intersection between:

Fan P-Q curve

and

Equipment system impedance curve

is the actual operating point.

This operating point determines:

• Actual airflow;
• Cooling performance;
• Noise level;
• Fan operating condition.

Therefore:

A fan with higher maximum airflow may not provide better cooling if it lacks sufficient static pressure in a high-resistance system.

A properly matched fan can achieve better thermal performance even with lower rated airflow.

5. System impedance;
6. Noise requirements;
7. Service life;
8. Operating environment.

Especially for:

• Medical equipment;

Conclusion

Can a 60×60×10mm ultra-thin axial fan replace a 60×60×25mm axial cooling fan?

The answer depends on:

Whether the fan performance meets the actual operating point requirements of the equipment.

The three common 60mm fan sizes:

• 60×60×10mm;
• 60×60×25mm;
• 60×60×38mm;

do not have absolute advantages or disadvantages.

Different applications require different solutions:

• Limited space → Choose ultra-thin fans;
• General industrial equipment → Choose 25mm standard fans;
• High heat and high resistance applications → Choose 38mm thick fans.

Through proper industrial fan selection and airflow-pressure analysis, even thinner fans can achieve stable and reliable cooling performance.
