  • The Sunon KD1204PKV3 Features,
    • Impedance Protection (ZP): Prevents the motor from electrical burnout if the fan blades become physically blocked.
    • MagLev Design: Eliminates standard mechanical friction, allowing for a longer lifespan (~50,000 hours) and lower acoustic signature.
    • Wiring Connection: Configured with a standard 3-pin standard motherboard/PCB layout.
  • KD1204PKV3 MS.M ZP CLE N0143 Gigabyte 22SF3-100402-31 Part Number Breakdown:
    • 'KD' DC Brushless Fan series
    • '12' 12V DC rated operational voltage
    • '04' 40mm Frame Width / Height
    • 'P' Outer frame style/profile code (denoting PBT plastic square shell).
    • 'K' Structural configuration code for 20mm thickness casing.
    • 'V' Vapo Bearing / MagLev mechanism.
    • '3' Speed profile tier classification (Low to Medium-Low speed tier)
    • 'MS' used to indicate specific combinations of internal motor housing materials, winding specifications, and compliance architectures
    • '.M' stands for "MagLev Motor Series" utilizing a specific revision of internal housing materials. It tells the factory that the stator and internal sleeve housing must be milled to accommodate Sunon's proprietary magnetic levitation field
    • 'ZP' (Impedance Protection / Zero Protection): This is a safety classification. It stands for Impedance Protected. It means that if the fan blade gets physically blocked or jammed (a locked rotor event), the internal motor coils are designed to resist overheating or catching fire, automatically cutting or choking power to protect the server's motherboard circuitry
    • 'CLE' (Custom Lead Wire & Electronics): This specifies the physical cable arrangement and internal hardware configuration. It tells the factory exactly how to prep the fan before shipping. For this model, it specifies a 3-wire lead configuration (Positive, Negative, and a Tachometer/Frequency Generator pin for RPM tracking) with a specialized terminal connector housing that plugs into the Gigabyte server board
    • 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.
      • 'N0143' (Customer Account / Project ID): This is a highly specific factory lot control number assigned to Gigabyte. Sunon assigns these numerical or alphanumeric sequences (often 4 or 5 digits) to denote unique customer-tailored variations, covering everything from custom wire lengths, precise connector pin arrangements, or a unique physical bracket pre-attached to the fan
    • 'Gigabyte 22SF3-100402-31'
      • Proprietary replacement cooling for Gigabyte Enterprise Servers, 1U/2U rackmount chasses, and networking equipment
      • High-density industrial network switches, power supplies (PSUs), and small form factor (SFF) computer systems requiring constant uptime
