Zyvpee KSB0605HBA03B6E 4 Pin Ball Bearing Case Fan

Replacement Cooling for Specific Notebooks

This Zyvpee KSB0605HBA03B6E is a 4-pin ball-bearing CPU fan built for X556, FL5900U, V556U, A556U and X556UB notebooks. It draws power through a standard four-wire connector and uses ball bearings for consistent rotation. The non-LED, two-tone housing keeps the focus on airflow rather than lighting. It serves as a direct mechanical match for the listed models.

Suitable for Targeted Laptop Repair

Technicians restoring cooling performance on the exact notebooks named above will find the correct pinout and mounting alignment. Builders working on desktop towers, custom water loops or any laptop outside the X556, FL5900U, V556U, A556U and X556UB series should look elsewhere because the connector keying and screw spacing will not match. Buyers who need RGB illumination or PWM software control beyond basic speed regulation are not served by this unit.

Fits Inside Listed Chassis Without Modification

The fan slots into the existing heatsink assembly of the compatible notebooks, requiring no adapter cables or bracket changes. Its four-wire interface connects directly to the motherboard header, freeing the builder from sourcing proprietary converters. Ball-bearing construction reduces the risk of rattling that sleeve bearings develop over time, preserving acoustic consistency throughout the repair lifecycle.
