792348-001 HPE PROLIANT Front System ML150 G9 Server Fan

Compatibility and Fit: Exact Match for HPE ProLiant ML150 G9

The 792348-001 fan assembly is an exact-fit cooling module designed for the HPE ProLiant ML150 G9 series. Compatibility is essential for servers where the thermal design, chassis airflow paths, and management interlocks are tuned to specific fan modules. This category describes the fan with holder as either the OEM HP/HPE part or a verified equivalent that conforms to HPE mechanical mounting points and electrical connectors.

Supported Models and Chassis Variants

Although primarily associated with the ML150 G9 tower/rack convertible chassis, the 792348-001 part may also be compatible across certain HPE chassis revisions that share the same fan cage design and power/monitoring connectors. Verify compatibility by matching the server product number (SPN), chassis part number, and system board connector positions. The product listing in this category usually includes a compatibility table with supported system board revisions and chassis part codes.

Connector, Pinout and Electrical Interface

Proper operation demands an electrical interface that provides power, tachometer feedback (RPM), and sometimes PWM/monitor control. The 792348-001 assembly typically uses the HPE standard multi-pin fan connector compatible with the ML150 G9 system board. The product descriptions in this category detail the connector type and pin functions so you can confirm it matches your system board’s header — avoiding accidental fitment of visually similar but electrically incompatible fans.

Technical Specifications and Performance Metrics

This section gives the technical snapshot that informs procurement and deployment decisions: fan type, RPM range, airflow (CFM), static pressure, acoustic level (dB), voltage and current ratings, form factor and holder material. Where available, datasheet excerpts are summarized and translated into practical impact statements — for instance, how increased static pressure benefits dense front-to-back airflow in populated drive bays.

Airflow (CFM) and Static Pressure

Airflow is the primary metric for cooling effectiveness. The 792348-001 assembly is specified for a targeted CFM at rated voltage and RPM. If your server installation includes high-density CPU and GPU configurations or tightly packed drive cages, static pressure capability becomes equally crucial. This category compares typical CFM numbers and static pressure ratings, explaining how each parameter translates into thermal headroom for common ML150 G9 configurations.

RPM Range and Fan Speed Control

Fan speed profiling is often handled by the server’s integrated management (iLO) or BIOS thermal firmware. The 792348-001 supports a broad RPM range so the host can modulate speed according to temperature sensors and workload. Lower RPMs reduce noise and power draw during light loads; higher RPMs provide rapid heat evacuation under heavy loads. The description clarifies whether the fan supports PWM-based control versus fixed-voltage control.

Noise Levels and Acoustic Considerations

Noise is a real-world consideration for labs, offices, and edge data centers. This category provides calibrated decibel ratings (dBA) at typical operational RPMs and explains trade-offs between noise and airflow. For deployments where acoustic constraints matter, we recommend pairing the 792348-001 with workload scheduling that reduces peak thermal events or selecting chassis configurations with better acoustic attenuation.

Power Consumption and Thermal Ratings

Knowing the wattage draw and heat rejection capacity is crucial for power budgeting and rack-level thermal planning. The 792348-001 part’s rated voltage and current draw are listed in product specifications; from these values you can estimate incremental power draw per fan and cumulative impact for multi-fan chassis configurations. This section walks through example calculations for common ML150 G9 builds so purchasers can integrate fan power into their rack PDU and UPS provisioning.

Physical Design, Holder Construction, and Longevity

The fan with holder is more than a spinning motor — the mechanical assembly, materials, and mounting design determine fitment reliability and vibration characteristics. This portion of the category description explains the holder architecture, fastener locations, anti-vibration features, and material choices (e.g., flame-retardant plastics, metal reinforcements). We also provide inspection tips to spot shipping damage or manufacturing defects.

Mounting Points and Fastening Guidelines

Proper mounting guarantees consistent airflow and prevents cyclic vibration that can shorten component life. Follow the specified torque values and fastener sequences where provided. The category lists common fastener types used on ML150 G9 fan cages and includes best practices for reusing captive screws versus replacing them during service.

Material Durability and Heat Resistance

Server components operate in elevated ambient temperatures. The holder’s polymer must resist deformation under heat and maintain dimensional stability over time. We describe expected operating temperature ranges and how to inspect the holder for signs of aging, such as cracking near screw bosses or discoloration that suggests prolonged thermal exposure.

Ordering, Part Numbers, and Purchasing Guidance

Buying the right spare is critical. This category clarifies the difference between the HPE OEM 792348-001, manufacturer-branded parts, and third-party compatible assemblies. We list valid alternative part numbers, commonly bundled SKUs, and remind buyers to inspect seller return policies and warranty terms.

Genuine OEM vs Compatible Aftermarket Assemblies

OEM parts generally carry the original manufacturer’s warranty and are guaranteed to match the thermal profile for the server. Compatible aftermarket assemblies can offer cost savings but vary in quality. We recommend sourcing compatible parts from verified suppliers who provide detailed electrical and mechanical compliance data and offer a return window in case of mismatch.

Bulk Purchasing and Spare-Parts Planning

For larger fleets, purchase spares based on Mean Time Between Failures (MTBF) estimates, criticality of uptime, and historical replacement rates. This category includes sample formulas to calculate recommended spare levels for typical data center populations of ML150 G9 servers and discusses the trade-offs between stocking spares locally versus relying on rapid-delivery vendors.

Cross-sell and Related Spare Parts

To complete a service kit or to optimize maintenance outings, consider these complementary components: additional fan modules for multi-fan chassis, fan cages, replacement screws and clips, thermal sensors, cable harnesses, and system board connectors. Bundles in this category often include a primary fan plus two spares and a small toolkit for in-field service.

Recommended Spares and Bundles

Example recommended kits include: single-swap kit (one 792348-001 + mounting screws + connector clip), fleet kit (3–5 fans designed for scheduled replacements), and service kit (fans + cable harnesses + anti-vibration pads). These bundles reduce mean time to repair and ensure consistent spare quality.

Buyer Checklist

Use this practical checklist to confirm before ordering:

• Server model and chassis revision match the compatibility table.
• Connector and pinout are identical or explicitly supported.
• RPM and airflow specs meet your thermal requirements.
• Acoustic levels are acceptable for your deployment environment.
• Supplier warranty, return policy, and RMA process provide acceptable protections.
• You have the mounting hardware and any needed spare screws.
• Spare inventory strategy aligns with your availability and uptime objectives.

How to Compare Alternatives

When evaluating alternatives, compare apples to apples: verify airflow at the same static pressure point, check whether the connector supports RPM reporting and control, and ask for measured acoustic data. A visually similar fan that lacks correct control signals can trip thermal throttling alarms or cause the server to run in a degraded state.

Documentation and Additional Resources

For administrators who require validation, consult official HPE parts catalogs and server maintenance manuals to cross-check service part numbers and removal/installation instructions. Archived firmware release notes sometimes contain thermal management updates that affect how the server controls fan speed; ensure your server firmware aligns with best-known configurations for the ML150 G9.

Conformance, Safety and Regulatory Notes

Server components may carry certifications and ratings such as RoHS, REACH, and UL flammability ratings for plastics used in holders. This category flags known certifications and reminds buyers to request compliance documentation if their procurement requires environmental or safety compliance evidence.
