The "Performance Limits" and Selection Logic of Various Cooling Fans

Different types of cooling fans do not have superiority or inferiority; they merely differ in their suitability.

Axial-flow cooling fans: Focus on high air volume, low noise, and low cost, suitable for scenarios with spacious space and no complex obstructions, and are the choice for the general public;

Centrifugal cooling fans: Centered on high air pressure and strong adaptability, suitable for scenarios with narrow channels and airflow obstructions, and are the choice for experts in complex environments;

Cross-flow cooling fans: Focus on uniform airflow and low noise, suitable for slender cooling spaces, and are the experts in precise coverage;

Mixed-flow cooling fans: Centered on the balance of air volume and air pressure, suitable for scenarios that need to consider both, and are the flexible compromise solution;

Ultimately, the core logic of selection is to start from the equipment requirements, clearly define the equipment's heat generation power, cooling space, and air resistance, and then combine parameters such as air volume, air pressure, and noise, to select a cooling fan type that matches the performance and has a reasonable cost, so that the cooling system can be both efficient and stable, and safeguard the long-term operation of the equipment.
