Fancasee 1 to 10 Way Fan Hub Splitter Extension Cable User Manual

1. Introduction

This manual provides comprehensive instructions for the installation, operation, and maintenance of your Fancasee 1 to 10 Way Fan Hub Splitter Extension Cable. This device is designed to efficiently power and manage multiple 4-pin and 3-pin PC case cooling fans from a single motherboard PWM header and a SATA power connection, enhancing the cooling capabilities of your desktop computer case.

2. Product Overview

The Fancasee 1 to 10 Way Fan Hub Splitter is a compact solution for expanding your system's fan connectivity. It allows up to ten PC case fans to be powered via a single 15-pin SATA power cable and controlled by a single PWM signal from your motherboard. This hub is compatible with both 4-pin and 3-pin fans, providing centralized control and power distribution.

Key features include:

• Supports up to 10 PC case fans (4-pin or 3-pin).
• Powered by a standard 15-pin SATA power connector for stable power delivery.
• PWM interface connects to the motherboard's CPU_FAN port for centralized speed control.
• Offers greater flexibility for fan placement within the PC case.
• Includes self-adhesive backing for secure mounting.

3. Package Contents

Please verify that all items are present in your package:

• 1 x Fancasee 1 to 10 Way PC Case Fan Hub
• 1 x PWM cable (used to connect the hub's PWM interface with the CPU_FAN port on the motherboard)

4. Setup Instructions

Follow these steps to install the Fancasee Fan Hub Splitter in your computer case:

1. Mount the Hub: Choose a suitable location within your PC case. The hub features a self-adhesive backing for secure mounting. Ensure the chosen surface is clean and dry before attaching.

2. Connect SATA Power: Connect a 15-pin SATA power cable from your power supply unit (PSU) to the 15-pin SATA power supply interface on the fan hub. This connection provides power to all connected fans.

3. Connect PWM Control Cable: Use the dedicated PWM cable included in the package. Connect one end to the red PWM interface on the fan hub (labeled "CPU-FAN" or similar) and the other end to the CPU_FAN port on your motherboard. This connection allows the motherboard to control the speed of the fans connected to the hub.
4. Connect PC Case Fans: Connect your 4-pin or 3-pin PC case fans to the available fan interfaces on the hub (labeled "FAN-0" through "FAN-9"). It is recommended to connect the primary CPU fan (if using the hub for it) to the red PWM interface for optimal speed control. Note that 3-pin fans will receive power but will not have PWM speed regulation functionality through this hub, running at a static speed determined by voltage.

5. Operating Instructions

Once installed, the Fancasee Fan Hub operates by distributing power from the SATA connection and relaying PWM speed control signals from your motherboard. The fan speed will be regulated by your motherboard's BIOS settings or fan control software, typically based on CPU temperature or other system parameters.

• PWM Control: For 4-pin fans connected to the hub, their speed will be controlled synchronously by the PWM signal from the motherboard's CPU_FAN header.
• 3-Pin Fan Operation: 3-pin fans connected to the hub will receive constant power and will typically operate at their maximum speed, as they do not support PWM speed modulation.
• BIOS/Software Settings: Refer to your motherboard's manual for instructions on configuring fan speed curves and monitoring fan performance through BIOS settings or dedicated software.

6. Maintenance

The Fancasee Fan Hub requires minimal maintenance. To ensure optimal performance and longevity:

• Regular Inspection: Periodically check all cable connections to ensure they are secure and free from damage.
• Dust Removal: If dust accumulates on the hub, gently clean it with a soft, dry cloth or compressed air. Ensure the computer is powered off and unplugged before cleaning.
• Environmental Conditions: Operate the hub within a standard PC case environment, avoiding excessive heat, humidity, or direct exposure to liquids.

7. Troubleshooting

If you encounter issues with your Fancasee Fan Hub, consider the following troubleshooting steps:

• Fans Not Spinning:
  • Ensure the 15-pin SATA power cable is securely connected from the PSU to the fan hub.
  • Verify that the PSU is providing power.
  • Check if individual fans are properly connected to the hub.
  • Test fans directly with a motherboard header to confirm they are functional.
• No PWM Speed Control:
  • Confirm that the PWM cable is correctly connected from the hub's red PWM interface to the motherboard's CPU_FAN port.
  • Ensure that the fans you are trying to control are 4-pin PWM compatible fans. 3-pin fans do not support PWM speed control.
  • Check your motherboard's BIOS settings to ensure PWM control is enabled for the CPU_FAN header and that a fan curve is configured.
  • Verify that the fan connected to the red PWM interface on the hub is a 4-pin fan, as this port is typically used to relay the RPM signal back to the motherboard.
• Loose Connections: Re-seat all cables (SATA power, PWM control, and fan cables) to ensure firm connections.
