Who it fits

Key specs explained

10-way fan support

This hub connects up to ten 4-pin PWM fans at once. You can expand your cooling setup without needing extra motherboard headers. This helps users with many case fans who run out of ports. It centralizes control for easier cable management. Check your motherboard's available headers to see if you need this expansion.

15-pin SATA power

The device draws power directly from your power supply via a SATA cable. This reduces the electrical load on your motherboard's fan headers. You get stable power for all connected fans. It separates speed control from power delivery. Ensure you have a free SATA power connector available in your system.

3.94 inches length

The unit is 3.94 inches long. This compact size fits easily into most PC cases. It does not take up much room near your motherboard. You can mount it on flat surfaces using the included adhesive. Compare this to larger hubs that might block other components or cables in tight builds.

3-pin and 4-pin compatibility

The hub works with both 3-pin and 4-pin fans. You can mix older and newer fans in one setup. The 4-pin PWM interface allows for speed regulation. The 3-pin fans will run at full speed or basic PWM control. Verify your existing fans match these connector types before purchasing.

Design and Build Details

The listing describes the CybNemo 10-Way Fan Hub as a compact unit measuring 3.94 inches in length, 1.57 inches in width, and 0.39 inches in height. These dimensions allow it to fit into tight spaces within your PC chassis without obstructing airflow or other components. The small footprint is a practical choice for builders who want to add cooling without cluttering the interior.

According to the listing, the back of the printed circuit board features 3M adhesive. This allows you to stick the hub firmly to the case shell or a flat surface. This mounting method keeps cables organized and prevents the hub from moving around. It helps you manage messy fan cables by centralizing connections away from motherboard headers.

The device uses a 15-pin SATA connector for power. This design reduces the load on your motherboard by drawing energy directly from the power supply. The PWM control connects to the CPU-FAN interface, allowing speed regulation for up to ten 4-pin fans. The listing notes that a specific red interface handles speed signals, while black interfaces provide conventional power. This separation ensures stable operation for your cooling setup.

Setup and Everyday Use

Setting up this hub is straightforward. You connect the SATA power cable to a 15-pin SATA port on your power supply. This provides stable power and reduces the electrical load on your motherboard. Next, you attach the PWM control cable to a CPU-FAN header on your motherboard. The listing notes that the red interface handles speed regulation, while the black interface serves as a conventional PWM port without speed signals. Both maintain PWM functionality. You can then plug up to ten 3-pin or 4-pin fans into the hub. This includes case fans, CPU coolers, and other cooling devices. The hub supports simultaneous startup for all connected fans. For placement, the back of the PCB features 3M adhesive. You can stick the unit to the inside of your case or any flat surface. Its compact dimensions of 3.94 by 1.57 by 0.39 inches help it fit into tight spaces. In daily use, this setup helps manage messy cables by centralizing connections. It solves the issue of insufficient motherboard fan headers. You get organized cooling control without cluttering your motherboard area. The design separates power delivery from speed control signals. This keeps your system running smoothly. The hub is compatible with standard desktop and computer case fans. You do not need to worry about mismatched connectors, as it works with both 3-pin and 4-pin options. This makes it a practical choice for expanding your cooling capacity.

Before You Buy This Hub

You need a free 15-pin SATA power connector from your PSU. The hub draws power this way, so ensure your power supply has an available port. You also need a free 4-pin CPU-FAN header on your motherboard for PWM speed control. The listing specifies the red interface connects to this header for regulation. Black interfaces are for fans without speed signals. Verify your fans are 12V 3-pin or 4-pin models. This hub is not a standalone solution. It works best alongside other case fans and cooling components. You must manage the cable routing yourself. The adhesive back helps secure it, but you should clean the surface first. This device expands your fan count without adding motherboard load. It fits well in builds with many chassis fans. Check your case space for the 3.94-inch length. Ensure you have enough SATA power cables. This setup centralizes control and keeps your build tidy. It is a practical addition for high-fan-count systems.

Check before you buy

• Check for a free 15-pin SATA power connector on your PSU.
• Verify a free 4-pin CPU-FAN header exists on your motherboard.
• Confirm all fans are 12V 3-pin or 4-pin models.
• Ensure your case has space for the 3.94-inch hub.
• Have enough SATA power cables for the hub connection.
