Thermalright TL-FAN Hub X4 4-Port PWM Fan Controller Hub, Black

The Thermalright TL-FAN Hub X4 solves the most common frustration in PC building: running out of motherboard fan headers. Instead of daisy-chaining splitters that overload a single port, this compact hub gives you four independently protected 4-pin PWM outputs driven by one motherboard signal. All connected fans spin in perfect synchronization, following the same curve you set in BIOS or software — no extra controllers, no software required.

Highlights

• Expands one motherboard PWM header to four fan ports, ideal for mid-tower and full-tower builds.
• SATA-powered design delivers stable 12V DC, supporting up to 4.5A total across all ports.
• Each port is rated for 1A, enough for high-performance fans without risk of overloading the header.
• Compact black ABS housing with adhesive pad for clean, tool-free mounting inside the case.
• Includes PWM signal cable and SATA power cable — everything needed for immediate installation.

In daily use

After connecting the hub to a free motherboard PWM header and a SATA power lead from your PSU, you can plug in up to four standard 4-pin PWM fans. The hub passes the PWM control signal to all fans simultaneously, so they ramp up and down together based on CPU or GPU temperature. Because power comes from the SATA connector rather than the motherboard, you avoid the risk of burning out a header when running multiple high-RPM fans. The adhesive backing keeps the hub securely in place on a flat surface, preventing rattles and keeping cable runs tidy.
