Boyd’s DWDI blowers provide a lot of cooling airflow in a small package and were developed to air-cool densely populated electronics where low noise and vibration are critical requirements. Competing dual axial counter-rotating fans operate significantly louder with more airborne vibration and ear-piercing tones.
Axial Fan vs DWDI Blower 40 mm High Mode
This is a demo unit that contains both the 40mm DWDI blower and a competing 40mm dual axial fan
40 mm measurements: 40x40x56mm, representing a 1U server rack height
(First sound) Axial Fan 40mm High Mode
(Second sound) Blower 40mm High Mode
The 40mm DWDI blower operates at about 4-8 dBA lower than the axial fan and with much lower tonality.
Axial Fan vs DWDI Blower 80 mm High Mode
This is a demo unit that contains both the 80mm DWDI blower and a competing 80mm dual axial fan
80 mm measurements: 80x80x80 mm
(Third sound) Axial Fan 80 mm High Mode
(Fourth sound) Blower 80 mm High Mode
The 80 mm DWDI blower operates at about 5-9 dBA lower than the axial fan and with much lower tonality.
Customers have seen overall sound power reductions of 6-12 dBA with Boyd’s DDI blower vs. Competing dual axial fans.
Advantages- Reduced airborne vibration for sensitive systems like hard disk drive storage. Axial fan efficiency matched with good application engineering and system design implementation. Good performance in straight through airflow configurations with sidewalls close to blower inlets.
