How do I choose the right cooling fan for my application?

October 21, 2026 | FAQ

Selecting the right cooling fan involves several factors:

1. **Airflow Requirements (CFM):** Calculate the heat dissipation needed for your system. A general guideline is 1 CFM per 3-5 watts of heat for typical electronics.

2. **Size Constraints:** Measure the available space in your enclosure. Common sizes include 40mm, 60mm, 80mm, 92mm, 120mm, and 200mm.

3. **Voltage:** Match the available power supply. Common DC voltages are 5V, 12V, 24V, and 48V.

4. **Noise Level:** Consider the operating environment. Noise is measured in dBA – lower is quieter.

5. **Environmental Conditions:** For dusty or humid environments, look for IP-rated fans (IP54, IP55, IP67).

6. **Control Options:** PWM control allows precise speed regulation based on temperature sensors.
