Cooling fan speed and pressure level

If you aim to double the maximum air volume, two approaches can be considered: increasing the Fan speed or augmenting the number of fans. According to the aforementioned calculation formula, these methods result in notably different sound pressure levels. Therefore, to minimize the sound pressure level as much as possible, increasing the number of fans proves to be more effective. Consequently, adjusting both the fan speed and the number of fans can serve as viable solutions during equipment design.
