Enhance your PC cooling system with this high-performance PC Chassis Fan Hub, designed to efficiently expand a single motherboard fan interface into multiple PWM-controlled ports. Crafted from durable metal, this fan hub is ideal for 12V motherboard fans with 3-pin or 4-pin connectors, providing optimal fan management and reducing motherboard load for improved system stability. Key Features: · **Motherboard Interface Expansion:** Converts one motherboard CPU fan interface into multiple PWM fan ports, allowing uniform speed control of several fans from a single connection. · **PWM Compatibility:** The red cable connects directly to the CPU fan header with speed sensing, while black cables provide standard PWM fan control ports without speed measurement, ensuring broad fan compatibility. · **Direct Power Supply:** Powered directly through the PSU via SATA interface, minimizing motherboard load and ensuring stable power delivery to your fans. · **Temperature Control Integration:** Separates the PWM temperature control line from the motherboard, enabling precise and accurate fan speed adjustments according to thermal conditions. · **3-Pin and 4-Pin Fan Support:** Supports both 3-pin and 4-pin fans for flexible installation; note 3-pin fans will operate at full speed as they lack PWM speed control functionality. · **Convenient Installation:** Equipped with adhesive backing and a screw hole for secure mounting on any flat surface inside your PC chassis. · **Robust Metal Construction:** Built from premium metal material for durability and stable performance in demanding PC environments. Specifications: · Material: Metal · Suitable For: 12V motherboard 3-pin and 4-pin fans (3-pin runs at full speed without PWM control) · Interface Type: Large 4D interface, SATA interface (for power supply) Package Includes: · 1 x PC Chassis Fan Hub This PC Chassis Fan Hub is an essential accessory for builders and enthusiasts looking to streamline fan management, reduce motherboard load, and maintain an efficient cooling setup. Its reliable metal construction combined with versatile fan and power support ensures smooth and quiet operation tailored to your system’s thermal demands.
