HP Inc 4N007AA HP Z2 TWR DL Frnt FAN

HP Inc 4N007AA Z2 Tower Dual-Layer Front Fan

Overview

The HP Inc 4N007AA is a factory-replacement front intake fan designed for the HP Z2 Tower workstation. When the original front fan fails or needs replacement during a field service call, the 4N007AA restores proper airflow through the chassis — preventing thermal throttling on the CPU, GPU, and storage subsystems housed in the Z2 Tower. At 0.45 lb and measuring 8.90 x 7.10 x 1.60 in, it is a direct drop-in swap with no modification required.

Compatibility

The 4N007AA is designed specifically for the HP Z2 Tower (TWR) workstation platform. Verify your chassis designation is Z2 TWR before ordering — the Z2 Small Form Factor (SFF) and Z2 Mini use different thermal assemblies and are not compatible with this fan. Cross-reference against the HP General Product Safety documentation (GPSR reference: HP support document ISH_6126692) if you need to confirm the exact chassis revision supported.

Installation Notes

The fan mounts in the front intake bay of the Z2 Tower case. Color is black, matching the standard Z2 Tower interior. No additional tools or adapter cables are referenced in the product data — standard Z2 Tower disassembly procedure applies. Confirm power connector compatibility with your specific Z2 Tower revision before installation, as HP occasionally revises internal connector configurations across chassis generations.
