5-Pack 4-Pin PWM Fan Extension Cable (25cm / 9.8"), High-Density Black Braided TX4 CPU & Case Fan Power Cable, Male to Female Wire Backward Compatible with 2-Pin & 3-Pin Fans

Streamline internal cable routing and effortlessly extend cooling reach inside your computer chassis with this 5-Pack 4-Pin PWM Fan Power Extension Cable (25cm / 9.8"). Encased in premium high-density black braided sleeving with reinforced heat-shrink tubing at both ends, each cable extends the connection between your motherboard fan headers and case cooling fans. Full 4-wire pass-through ensures complete PWM automatic speed regulation and real-time RPM tachometer monitoring, while remaining fully backward compatible with 3-pin and 2-pin fans.

• Full 4-Wire PWM Signal Pass-Through: Features a complete 4-conductor pinout (Ground, +12V Power, Tachometer RPM Speed Sensor, and PWM Duty-Cycle Signal). Fully preserves motherboard BIOS and software temperature-controlled fan speed curves.
• Backward Compatible with 3-Pin & 2-Pin Fans: The standardized male TX4 connector housing accommodates standard 4-pin PWM fans, as well as classic 3-pin DC voltage fans and 2-pin chassis fans (3-pin and 2-pin fans operate at steady full speed).
• Premium High-Density Braided Sleeving: Wrapped in an abrasion-resistant, tightly woven black nylon mesh sleeve. Protects internal conductors against sharp metal chassis edges while delivering a sleek, stealthy, all-black aesthetic for custom PC builds.
• Reinforced Industrial Heat-Shrink Tubing: Both connector terminals are secured with high-grade flame-retardant heat-shrink tubing, preventing wire pull-out, internal fraying, and terminal loosening during intensive cable routing.
• Optimal 25cm (9.8") Cable Extension: Provides ample length to reach distant top-mounted radiators, front intake fans, and rear exhaust ports around motherboards, eliminating unsightly cable tension behind the chassis tray.
• Economical 5-Pack Bundle: Includes 5 identical premium extension cables, ideal for fully outfitting multi-fan gaming workstations, liquid cooling radiators, and mining chassis.
• Product Type: 4-Pin PWM Case & CPU Fan Power Extension Cable (5-Pack)
