Archive recordRecord full part number, hardware revision, serial/date code, firmware/BIOS, accessories, physical condition, and the documentation revision used for verification.

Compatibility and handling

  • Confirm the complete part number, connector signal/pinout, supported host, dimensions, power, firmware and operating-system requirements before use.
  • Inspect for corrosion, cracked parts, bent pins, damaged insulation, failing bearings, leaking cells, or prior repair. Avoid powering unidentified or damaged hardware.
  • For compatibility claims, cite a specific manual, CPU support list, interface standard, or tested host configuration; physical fit alone is insufficient.
  • Record measurements with the test setup and instrument conditions; distinguish vendor maximums from measured or sustained results.

Model notes

Check header current budget, radiator/guard clearance, and airflow direction indicated by frame arrows.

NF-A12x25 PWM, FLX, ULN, and chromax variants use different control/connectors and speed ranges.
