Delta PFR0812DHE-F00 12V High-Pressure DC Axial Fan

The PFR0812DHE-F00 is a high-performance DC axial cooling fan from Delta Electronics’ PFR series. It operates from a nominal 12V DC supply and uses an 80 × 80 × 38mm frame.

With a maximum speed of 11,000 RPM, maximum airflow of 109.70 CFM and maximum static pressure of 2.187 inchH₂O, the PFR0812DHE-F00 is designed for equipment with dense internal structures and high airflow resistance. Typical applications include GPU and AI servers, storage systems, telecom equipment, industrial computers and other high-heat-density electronic equipment.

The F00 version uses three lead wires and includes a speed sensor output, allowing the host system to monitor fan rotation. It does not provide PWM speed-control functionality.

Technical Specifications

Airflow and static-pressure figures are maximum values measured at different points of the fan performance curve. The actual operating airflow depends on the resistance of the equipment’s complete airflow path.

Typical Applications

The Delta PFR0812DHE-F00 is suitable for cooling systems that require both high airflow and strong pressure capability, including:

• GPU, AI and high-density computing servers

• RAID, NAS and enterprise data-storage systems

• Network switches, routers and telecom equipment

• Industrial computers and edge-computing systems

• Power supplies, rectifiers and electronic load equipment

• Battery energy-storage control cabinets

• Automated test and measurement equipment

• High-density electronic enclosures

• Replacement of failed Delta PFR0812DHE-F00 fans

High Static Pressure for Restrictive Airflow Paths

The fan’s maximum static pressure of 55.55mmH₂O makes it suitable for equipment containing restrictive components such as densely packed heat sinks, drive cages, filters, cable bundles and narrow ventilation channels.

When selecting a replacement, airflow alone should not be used as the only criterion. A lower-pressure fan may fit the same mounting position but fail to move sufficient air through the actual equipment.

Speed Monitoring Function

The PFR0812DHE-F00 has three lead wires: two for fan power and one for the tachometer signal. The speed-feedback signal can be used by the host controller to:

• Monitor whether the fan is rotating

• Detect fan failure or abnormal speed

• Trigger equipment alarms

• Support preventive maintenance

• Improve cooling-system reliability

The tachometer signal should not be confused with a PWM control input. If the equipment requires four-wire PWM control, verify the complete Delta part number and control interface before ordering.

Power Supply and Noise Considerations

At its rated operating point, the fan consumes approximately 25.20W and draws 2.10A from a 12V supply. The equipment power supply, PCB traces, wiring and connector should have adequate current capacity, including suitable allowance for fan startup conditions.

The specified noise level is 66.0dB(A). This model is primarily intended for performance-oriented server, telecom and industrial applications where cooling capability takes priority over low acoustic noise. It is generally unsuitable for quiet office or consumer-PC applications.

Replacement Selection

When replacing a PFR0812DHE-F00, verify the following parameters:

1. Complete part number: PFR0812DHE-F00

2. Rated voltage: 12V DC

3. Operating voltage range: 7.0–13.2V DC

4. Frame dimensions: 80 × 80 × 38mm

5. Rated current: 2.10A

6. Airflow and static-pressure requirements

7. Three-wire tachometer interface

8. Wire length, connector type and pin sequence

9. Airflow direction and mounting orientation

Fans with the same 80mm frame size are not necessarily interchangeable. Differences in current, thickness, connector, pin assignment, rotational-speed signal and pressure performance may prevent correct operation.

Do not replace the three-wire PFR0812DHE-F00 with a two-wire or four-wire version without checking the equipment interface. Connector housings and wire colors can also vary between customer-specific suffixes.
