Description
The Delta QFR0812SH-AA39 is an 80mm x 80mm server cooling fan designed to move large volumes of air efficiently within a server chassis. Here's a more detailed breakdown:
Size and Design: This square-shaped fan measures 80 millimeters on each side and has a depth of 25.4 millimeters. Its compact size allows for easy integration into various server environments.
Performance: The fan delivers a maximum airflow of 54.57 CFM (cubic feet per minute), ensuring adequate air circulation to cool critical server components. It also generates a static pressure of 0.331 inH₂O (inches of water), which indicates its ability to push air against resistance within the server case. While effective, this fan operates at a speed of 4300 RPM, resulting in a noise level of 41.2 dB(A). This might be noticeable in quieter server environments.
Durability: The Delta QFR0812SH-AA39 utilizes a ball bearing design, known for its long lifespan and quiet operation compared to sleeve bearing fans. The manufacturer specifies a lifespan of 70,000 hours at 40°C ambient temperature, translating to over eight years of continuous operation.
Electrical Specifications: The fan operates on a standard 12VDC power supply and draws a maximum current of 0.33 amps. It connects via a 4-pin header, allowing for potential speed control through Pulse Width Modulation (PWM) by compatible systems. This allows the fan speed to be adjusted based on the server's thermal needs, potentially reducing noise output at lower operating temperatures.
Safety Features: The Delta QFR0812SH-AA39 incorporates locked-rotor protection, which safeguards the motor from overheating in case the fan blades become obstructed.
Supported Models
Unfortunately, due to the generic nature of server cooling fans, identifying specific server models compatible with the Delta QFR0812SH-AA39 is challenging. However, its specifications make it suitable for various servers requiring an 80mm x 80mm, 12V DC fan with high airflow capabilities.
