  • The Delta GFC0412DS is a,
    • Counter-Rotating Dual-Rotor Design: Pairs two independent motors back-to-back inside a single 40x56mm frame. One rotor draws air in while the other forces it out in the opposite rotational direction, generating massive static pressure (4.11 in-H2O).
    • Pulse Width Modulation (PWM): Built-in 4-wire or 8-wire dynamic speed control allowing the server motherboard to regulate RPM based on heat levels.
    • Integrated Safety Sensors: Features a Tachometer (Speed Sensor) for continuous system monitoring and Locked Rotor Protection to cut power if physical debris jams the blades.
  • GFC0412DS -BA42 EP TD -D 4621B10F Dell CMRFD DPN 0CMRFD A00 Part Number Breakdown:
    • 'GF' Delta Electronics proprietary high-performance dual-rotor, counter-rotating fan series code
    • 'C' Structural frame geometry code denoting a 40mm x 40mm profile
    • '04' Explains the physical depth/thickness of the dual-fan assembly housing (56mm)
    • '12' Indicates the standard requirement for a 12V DC operating input voltage
    • 'D' Explains the speed class classification (Super High-Speed Output)
    • 'S' Signifies a standard data transmission package containing a Tachometer/Speed output and standard Pulse Width Modulation capability
    • '-BA42' Dell custom identification modifier. This dictates the custom internal firmware calibrations, exact wiring harness length, and specific hot-swap pinned connector style required by Dell's server motherboards
    • 'EP/TD' Specific Delta internal manufacturing plant location designations, internal tracking lines, and regional environmental code compliance symbols
    • '-D' Pinouts structural interface variant used on specific hardware assemblies
    • Photos are representative of the model and specifications you will receive; however, the exact factory batch codes, manufacturing dates, and plant location stamps may differ across individual units.
      • '4621B10F' Unique factory production lot code, serial identifier, and manufacturing date matrix tracking stamp
    • Dell frequently assigns multiple different Part Numbers (PNs) to the exact same physical part known as "substitutes" or "cross-references", the exact Dell PNs may differ across individual units.
      • 'Dell CMRFD' The unique, base 5-character alphanumeric identification string assigned to this physical product part inside the global Dell asset infrastructure
      • 'DPN 0CMRFD' Officially means Dell Part Number. The character 0 is prefixed to complete requirements for 6-character inventory tracking barcodes
      • 'A00' Hardware revision state code. A00 tells the engineer it is the initial, first-generation manufacturing standard cleared for global deployment
