Product Features
Technical Overview
This power splitter cable features a 4-pin Molex female connector on one end that connects to your power supply or motherboard fan header. The opposite end splits into two 4-pin Molex male connectors, each capable of powering a standard PWM fan. The 4-pin design supports pulse-width modulation for precise fan speed control based on thermal requirements.
The cable construction utilizes durable materials that withstand repeated installation cycles and maintain reliable electrical connections. Each connector features sturdy housing that prevents bending or damage to the pins during installation and removal.

This fan splitter cable addresses common cooling expansion challenges in computer builds by providing a reliable method to add additional fans without requiring motherboard upgrades or specialized controllers. The PWM compatibility ensures that connected fans respond appropriately to system temperature changes, maintaining optimal cooling performance while minimizing noise during low-load conditions.
Dual Fan Support
Connect two standard 4-pin PWM fans to a single motherboard or power supply fan header, effectively expanding your cooling capacity without additional hardware.
- Maintains PWM signal integrity
- Supports simultaneous fan control
- Eliminates need for extra headers
Reliable Construction
Built with durable materials that ensure consistent electrical connections and withstand the physical demands of PC building and maintenance.
- Sturdy connector housings
- Quality wire insulation
- Repeated installation capable
Deployment / Use Cases
The FAN4SPLIT12 fan power splitter cable serves multiple practical applications in computer system configuration and cooling optimization. It's particularly valuable in systems where motherboard fan headers are limited but additional cooling is required for optimal thermal management.
Common deployment scenarios include adding a second exhaust fan in standard ATX cases, creating push-pull configurations on CPU coolers, or expanding chassis airflow in compact builds where header availability is constrained. The cable also proves useful in server environments where redundant cooling fans are necessary but header count is limited.
Physical Profile
With a 12-inch (1-foot) length, this splitter cable provides adequate reach for most PC case configurations while minimizing excess cable that requires management. The lightweight design at just 0.40 ounces adds minimal weight to your system and allows for flexible routing around components and through cable management channels.
The physical profile is practical for deployment planning because the dimensions and weight are clearly defined: 0.40 oz (11.34 g). This helps confirm rack, shelf, desk, or cabinet fit before installation.

User Manual
FAQ
What type of fans does the FAN4SPLIT12 cable support?
The FAN4SPLIT12 supports standard 4-pin PWM (Pulse Width Modulation) fans, specifically designed for CPU fan applications. The 4-pin design includes power, ground, tachometer, and PWM control wires, allowing connected fans to receive speed control signals from the motherboard or power supply for optimal thermal management.
Can I connect more than two fans using this splitter cable?
No, the FAN4SPLIT12 is designed specifically to connect exactly two 4-pin PWM fans to a single power supply or motherboard connector. Each cable has one female connector for the power source and two male connectors for fans. For connecting more than two fans, you would need additional splitters or a fan hub designed for higher fan counts.
Does this cable maintain PWM functionality for both connected fans?
Yes, the FAN4SPLIT12 maintains PWM signal integrity, allowing both connected fans to receive the same speed control signals from the motherboard or power supply. This ensures synchronized operation where both fans adjust their speeds simultaneously based on temperature readings, providing consistent cooling performance while minimizing noise during low-load conditions.
What is the maximum power rating for this splitter cable?
While the cable itself doesn't have a published maximum power rating, it's designed to handle the typical power requirements of two standard PWM fans. Most motherboard fan headers support up to 1A, which is sufficient for two standard 4-pin fans. Always verify that your specific fans' combined power draw doesn't exceed your power source's capabilities.
How long is the FAN4SPLIT12 cable?
The FAN4SPLIT12 measures 12 inches (1 foot or 0.30 meters) in length. This provides adequate reach for most standard PC case configurations, allowing you to route the cable from the motherboard or power supply to fan mounting locations while maintaining tidy cable management within the chassis.
What warranty comes with this fan splitter cable?
StarTech.com provides a lifetime limited warranty for the FAN4SPLIT12 fan power splitter cable. This warranty covers defects in materials and workmanship for the product's usable life, offering long-term assurance of quality and reliability for your cooling system expansion needs.
