Fan airflow performance

Airflow performance

On the previous page, you have been able to see the acoustics for 5V and 12V settings. We'll now focus on airflow, and, while an exact measurement, I'll classify this page as somewhat subjective. But we can get a good indication of airflow per fan at each setting.

With the help of a simple to use anemometer, we can see how airflow behaves. An anemometer is a device used to measure the speed of the wind and is also a common weather station instrument. The term is derived from the Greek word anemos, which means wind, and is used to describe any wind speed instrument used in meteorology. It's a relatively cheap device to get and does seem to provide pretty steady results. Each fan is measured with the anemometer positioned precisely, as shown above. Now we can measure how much air the fan is sucking inwards; the value is measured in meters per second; higher is, in this metric, better, of course. 

The included 140mm fans are absolutely powerful and capable.
