• Fan Thickness: 20 mm (ensure adequate clearance in enclosures)
• 4-Wire Interface:
• PWM control for adjustable fan speed
• Tachometer signal for RPM monitoring
• Power Consumption: 7.2 W (12 V × 0.6 A)
Performance & Suitability:
• Delivers efficient cooling in compact spaces thanks to 52.9 CFM airflow
• Suitable for chassis, small server cases, and OEM desktops (e.g., Dell OptiPlex 7010/9010)
• Hydraulic bearing design ensures quieter operation and extended durability
• PWM functionality allows dynamic speed adjustment for thermal control
Installation & Practical Notes:
• Requires 4‑pin PWM fan header or appropriate adapter
• Fan orientation: arrows on casing indicate airflow and rotation
• Check mounting hole alignment and connector compatibility if replacing an existing fan
• Ensure airflow path is unobstructed to maintain fan efficiency and reduce noise
Summary:
The DASA0820R2U is a reliable, high-performance 80 mm × 20 mm cooling fan with PWM speed control, a hydraulic bearing, and a notable 52.9 CFM airflow. Ideal for compact desktops and workstations needing controlled cooling, this fan balances strong airflow with long-term reliability.
