Volume flow (throughput) in m³h
The black bar is the specification from the data sheet, which we check with at this point. Let’s first start with the value for m² per hour, which is more common in Germany, and compare the individual installation variants from pure case fans to use on 60 mm radiators. It can be seen that the value is reasonably maintained or achieved. Since we test the fans in an installed state under real-world conditions, a slight undershoot of the specifications is quite possible and not a big deal as long as you stay below 5 percentage points. Because then you quickly get into the usual tolerance range for the whole fan series, where never all fans perform really identically.
Volume flow (throughput) in cfm
The whole thing again in cfm. However, since only the unit of measurement changes, what has already been said for the airflow applies to the same extent.
