Who it fits

Key specs explained for this hub

4-Pin Connector Type

This connector supports Pulse Width Modulation, allowing your motherboard to adjust fan speed automatically. You get precise control over cooling levels based on system temperature. This is standard for modern case fans. It ensures quiet operation at low loads and maximum airflow when needed. Always match this to your case fan headers for full functionality.

4 Port Capacity

The hub manages four separate fans from a single connection point. This simplifies cable management inside your case. You can control multiple fans without using many motherboard headers. This is ideal for builds with several intake or exhaust fans. It keeps your internal wiring tidy and organized.

SATA Power Direct Output

The device draws power directly from a SATA power connector on your power supply. This bypasses motherboard power limits, ensuring stable performance. High-load fans will run reliably without draining system resources. It provides consistent voltage even during peak usage. This method is common for reliable fan hubs.

500mm Cable Length

The included cable is 500 millimeters long, offering flexibility for placement. You can route the hub away from crowded areas. This length helps maintain a clean look inside your case. It allows mounting the hub on the side panel or behind the motherboard tray. Check your case dimensions to ensure it fits your layout.

Black Color

The unit features a black finish that blends with most internal components. It matches standard black cables and mounting hardware. This helps maintain a uniform aesthetic inside your case. It is a neutral choice that does not draw attention. This color is practical for hiding the hub behind panels or cables.

Design and build details

The Thermalright FAN HUB X4 PWM measures a compact size, weighing only 1.13 ounces. This light weight means it adds negligible load to your case structure. The unit features a black finish with the Thermalright logo engraved on the top surface. This simple aesthetic helps it blend into standard PC builds without drawing attention. You get a practical, unobtrusive look that prioritizes function over flashy design elements.

According to the listing, the hub includes strong double-sided stickers for mounting. This allows you to place the device in any suitable spot inside your case. You are not restricted to specific screw holes or drive bays. This flexibility simplifies installation, especially in cases with limited mounting options. You can position the hub near your fans to minimize cable runs. The goal is a cleaner interior with less visible clutter.

The device uses a 500mm long black cable for connections. This sufficient length gives you room to route wires neatly behind the motherboard tray or along case channels. A longer cable reduces tension on connectors and helps maintain a tidy layout. The SATA power input provides direct output, which the listing states maintains stable operation under high load. This design choice ensures your fans receive consistent power without voltage drops. The overall build focuses on straightforward integration and reliable performance for your cooling setup.

Setup and everyday use details

Installing the Thermalright FAN HUB X4 PWM is straightforward. You begin by connecting the SATA power cable directly to your power supply. This provides stable output even when all ports are active. The hub includes strong double-sided stickers. You can place the unit in any convenient location inside your case. This flexibility helps you keep cables organized and hidden. The included 500mm black cable offers enough length to reach your power source without stretching. This length allows for a clean internal layout. You can route the cable neatly along case edges. The hub supports four 4-pin PWM fans. You connect each fan to one of the four ports. This keeps your CPU fan cables neat and reduces clutter. One important detail involves the red interface port. Due to the PWM motherboard IC reading principle, only the fan plugged into the red port allows the motherboard to read single fan speed. Other ports do not support this specific readout function. This means you must plan your connections carefully if you need speed monitoring for all fans. For everyday use, the hub synchronizes fan speeds based on the connected PWM signals. You do not need additional software or apps. The device operates silently and efficiently. The compact size ensures it does not obstruct airflow or other components. The black finish blends well with most internal builds. You get reliable control over up to four fans with minimal effort. The design prioritizes function over form, ensuring consistent performance. This makes it a practical choice for builders who want tidy cable management and straightforward fan control without complexity.

Before you buy this hub

You need to verify your motherboard has an available SATA power connector. The hub draws power directly from this source, so a free port is essential. Check your case for mounting space. The included double-sided adhesive allows flexible placement, but ensure the surface is clean and smooth for a secure hold. You should also confirm your fans use 4-pin PWM connectors. The red port reads single fan speed, while the other ports adjust based on that reading. Keep the 500mm cable in mind. Its length offers flexibility, but you may need cable ties to keep it tidy. This hub fits well alongside other cooling solutions. It simplifies wiring for multiple fans. You get neat cable management without complex setups. It is a practical addition if you have four fans. It helps maintain a clean interior. The compact size ensures it does not obstruct airflow. You rely on stable output for consistent cooling performance.

Check before you buy

• Verify your power supply has a free SATA connector.
• Confirm your case fans use 4-pin PWM connectors.
• Ensure you have a clean, flat surface for mounting.
• Check that your motherboard supports PWM fan control.
