Fan Test Systems
Advanced Testing Systems for High-Performance Cooling Fans
At Sofasco™ International, we’ve spent decades perfecting not only our cooling fans but also the systems that ensure their performance, reliability, and efficiency in real-world conditions. We’ve developed a comprehensive set of test systems designed to validate AC, DC axial fans, cross blower, chip cooling, and muffin fans across a wide range of thermal and airflow scenarios.
- Every Sofasco fan undergoes structured validation that combines simulation, controlled lab testing, and real-world condition modelling.
- This engineering-driven approach ensures that performance data reflects actual operating environments, not just theoretical benchmarks.
- Validation workflows are designed to identify airflow limitations, thermal bottlenecks, and system resistance early in the design cycle.
Our Test Systems are:
1. Thermal Resistance Testing – Desktop Computers
- Five ambient temperature points with adjustable settings
- Max power input: 60W
- Online monitoring of current (A), voltage (V), and power (P)
- Visual Basic software for CPU temperature variation and thermal resistance tracking
Application: Ideal for validating chip coolers in high-load desktop environments.

2. Thermal Simulation – Notebook Computers
- Four ambient temperature settings
- Simulates CPU, HDD, and battery heat dissipation
- Eight additional temperature monitoring points
- RPM monitoring for case fans
- Live data logging via Visual Basic software
Application: Validates low-profile fans used in compact, heat-sensitive systems like notebooks and tablets.

3. Fan Performance & System Resistance Test Chamber
- Adjustable chamber with visualization
- Static pressure: 0–200 mmAq
- Airflow: 0–5000 CFM | Fan size: 25–500mm
- Fan characteristic curves:
Ps-Qv, Ptot-Qv, Pv-Qv, rpm-Qv, A-Qv, P-Qv - System resistance curve: Ps-Qv
- Online performance logging and analytics
Application: Engineers and OEMs use this to validate cooling system pressure drop and airflow behavior.

4. Heat Pipe Performance Test System
- Adjustable tilt angle: -15° to +15°
- Power input: 0–60W
- Real-time A, V, and P monitoring
- Charts the maximum heat transfer at different tilt angles and temperatures
Application: Critical for testing thermal management systems in aviation, LED systems, or vertical enclosures.
Testing outputs are used to:
- Predict system-level cooling performance before deployment
- Match fan curves to real impedance conditions
- Reduce overdesign and energy consumption
- Validate reliability under continuous operation
This allows engineers to move from trial-and-error to data-driven fan selection.
