• Multi-Channel Fan Support: Connects up to 7 or 8 fans simultaneously via 3-pin or 4-pin headers, perfect for mid-tower and full-tower builds.
• Manual Voltage Knob Control: Adjusts fan operating voltage to fine-tune airflow and noise levels. Supports fans that run at 7V or 12V for flexible compatibility.
• SATA Power Input: Draws power directly from your PSU's SATA connector — no extra adapters required for standard setups.
• PCI Bracket Mounting: Includes screws for secure, tool-assisted installation into a standard PCI expansion slot for a clean, integrated look.

Specifications

Good to Know

• Each individual channel is not rated for high-draw fans exceeding 1A. Please verify your fan's current draw before use.
• Fan extension cables and power extension cords are not included in the package.
• When adjusting voltage, a brief delay in fan response or a temporary stall is completely normal behavior — this is not a defect.

Frequently Asked Questions

Q: How many fans can this PC fan hub speed controller support at once?

A: This hub supports up to 7 or 8 fans simultaneously, depending on the model variant you receive. It is compatible with both 3-pin and 4-pin fan connectors, making it highly versatile for most desktop PC builds.

Q: Does the fan hub require any software to control fan speed?

A: No software is required. Fan speed is controlled manually via the onboard voltage-adjustment knob, which changes the output voltage between approximately 7V and 12V to speed up or slow down your connected fans.

Q: What power connector does this fan hub use?

A: The hub is powered by a standard SATA power connector from your PC power supply unit (PSU). No additional adapters are needed for most modern systems.

Q: Is it normal for my fan to briefly stop or not respond immediately after adjusting the knob?

A: Yes, this is completely normal. When you adjust the voltage knob, there may be a short delay before fans respond, or fans set to very low voltages may momentarily stall. This is an expected behavior of voltage-based speed control and does not indicate a product defect.
