Product Overview

Maximize your PC’s cooling potential with the OTOTEC 4-Pack PWM Fan Splitter Cable set, the ultimate solution for enthusiasts seeking a high-performance, silent, and organized build. Engineered for modern desktops, these 1-to-2 way converters allow you to connect multiple 12V case fans to a single 4-pin motherboard header without sacrificing intelligent speed control. By utilizing the Pulse Width Modulation (PWM) signal, your system can dynamically adjust fan speeds based on real-time thermal demands, ensuring whisper-quiet operation during light tasks and maximum airflow during intense gaming or heavy workloads. The ultra-compact 5cm cable length is specifically designed to eliminate the messy “cable nest” common in smaller builds, providing just enough reach to bridge connections while maintaining a pristine, professional interior aesthetic. Whether you are building a compact Mini-ITX powerhouse or a full-tower workstation, these durable adapters provide the reliability and flexibility needed to keep your components cool and your system stable.

Key Features

• Intelligent PWM Synchronization: Supports full 4-pin PWM functionality, allowing your motherboard to automatically regulate the speed of two fans simultaneously for optimized thermal management.
• Space-Saving 5cm Design: The short-profile cable length is perfect for clean cable management, preventing excess clutter and improving internal airflow within your PC chassis.
• Value-Driven 4-Piece Set: Includes four high-quality splitter cables, providing enough connectivity to expand your cooling array across multiple zones or future-proof your next build.
• Universal Compatibility: Designed for standard 12V 4-pin PWM fan headers and compatible with 3-pin DC fans (running at full speed), making them a versatile addition to any computer accessory kit.
• Durable Construction: Crafted with high-grade plastic and metal connectors to ensure a secure, tangle-free connection and long-lasting performance in high-temperature environments.

Important Information

• Motherboard Power Limits: Please verify that your motherboard fan header can handle the combined electrical load of multiple fans before installation.
• RPM Monitoring: Only one of the two output connectors typically carries the tachometer (speed) signal to the motherboard to avoid conflicting RPM readings.
• Installation Note: Ensure the 4-pin female end is securely seated on the motherboard header to maintain consistent signal transmission.
