  • The Sunon KD1204PKVX Features,
    • MagLev/Vapo Technology: Eliminates typical mechanical friction, drastically reducing wear, extending the fan lifespan, and allowing stable multi-axis mounting (vertical, horizontal, or angled) without oil-leakage issues.
    • High Static Pressure: Configured to push 0.27 Inch-H₂O of pressure, making it excellent at forcing air through highly restrictive obstacles like heatsink fins.
    • Auto-Restart & Locked Rotor Protection: Safeguards the circuitry from burning out if the blades become blocked by debris.

    • 'KD' DC Brushless Fan series
    • '12' 12V DC rated operational voltage
    • '04' 40mm Frame Width / Height
    • 'P' 20mm Frame Thickness
    • 'K' MagLev / Vapo-Bearing structural design
    • 'V' Vapor Bearing system
    • 'X' Ultra High-Speed performance tuning performance 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
