Key Features
80 x 80 x 25.4 mm Reference Frame
The Delta AUB0812H-E manufacturer drawing identifies an 80 mm square frame with 25.4 mm depth and 71.5 mm mounting-hole spacing. Confirm these dimensions for the -79C assembly before installation.
3900 RPM Family Performance
Delta specifies a rated speed of 3900 RPM ±10% for AUB0812H-E. A separate manufacturer performance approval for suffix -79C has not been established, so this is a family reference value.
50.15 CFM Reference Airflow
The AUB0812H-E approval specification lists 50.15 CFM maximum free-air flow and 0.239 inH₂O maximum static pressure. These represent different test endpoints and are not independently confirmed for -79C.
Sleeve Bearing Reference Design
Delta's AUB0812H-E specification identifies sleeve bearings, plastic frame and impeller materials, and an average acoustical noise level of 37.5 dB(A). Confirm the supplied -79C variant if these details are critical.
Three-Pin Listed Configuration
Complete-model -79C listings describe a three-pin connection. Delta's AUB0812H-E reference drawing identifies red positive, black negative and blue FG feedback leads, but the exact -79C connector and pin positions require verification.
Applications
- Electronic enclosure forced-air cooling
- Digital projector cooling systems with matching fan specifications
- Compact telecommunications equipment ventilation
- Industrial embedded computer cooling
- Electronic control module thermal management
- Networking equipment airflow
- Test and measurement instrument ventilation
- Maintenance of compatible AUB0812H-E-79C fan assemblies

Frequently Asked Questions
What is Delta Electronics AUB0812H-E-79C?
AUB0812H-E-79C is a Delta Electronics AUB-series DC axial fan identifier. Multiple complete-model sales listings specify 12 VDC, 0.30 A and a three-pin connection.
What supply voltage does AUB0812H-E-79C use?
Exact-model listings state 12 VDC. Delta's AUB0812H-E approval specification lists a 5.0–13.2 VDC operating range, which should be verified against the supplied -79C assembly.
What are the fan dimensions?
The manufacturer AUB0812H-E reference model measures 80 x 80 x 25.4 mm, with 71.5 mm mounting-hole spacing. A dedicated -79C mechanical drawing was not established.
Is the rated current 0.23 A or 0.30 A?
The Delta AUB0812H-E specification lists 0.23 A average input current, 0.30 A maximum average current and 0.30 A current printed on the label. Complete -79C seller listings also show 0.30 A.
What electrical power is specified?
Delta's AUB0812H-E approval lists 2.76 W average input power and 3.60 W maximum average input power. These belong to the documented -E configuration and are reference values for the -79C listing.
What is the reference rotational speed?
The Delta AUB0812H-E datasheet lists 3900 RPM ±10%. A separate suffix-specific speed approval was not found for AUB0812H-E-79C.
What is the maximum airflow?
The Delta AUB0812H-E reference specification states 50.15 CFM (1.421 m³/min) maximum free-air flow. This figure is not independently verified for the complete -79C suffix.
What is the maximum static pressure?
The reference AUB0812H-E specification lists 0.239 inH₂O (6.080 mmH₂O). Maximum pressure is measured at zero airflow, separately from the maximum free-air-flow point.
What is the listed acoustic noise?
The manufacturer states 37.5 dB(A) average and 41.5 dB(A) maximum for AUB0812H-E. This rating should be confirmed for a -79C assembly where acoustic performance is critical.
Does this fan have ball bearings or sleeve bearings?
The Delta AUB0812H-E manufacturer specification identifies a sleeve bearing, which is also shown by major component distributors. Bearing details for suffix -79C were not separately confirmed.
What does the three-pin connection provide?
The Delta AUB0812H-E reference drawing shows red positive, black negative and blue FG speed-feedback wires. Complete -79C sales records state three pins, but the connector keying and precise pinout must be checked before electrical connection.
What should be checked before ordering AUB0812H-E-79C?
Verify the complete AUB0812H-E-79C marking, 12 VDC input, 0.30 A label rating, actual 80 mm frame dimensions, mounting-hole pattern, fan thickness, connector type, three-pin wire order, feedback signal and cooling performance requirements against the installed equipment.
