Fan hub DeepCool FH-04 — 20‑pin ATX to 4× 3‑pin Molex, 0.55 m cable, black

The DeepCool FH-04 is a compact fan hub designed to expand and simplify chassis cooling. With a 20-pin ATX connector and four 3-pin Molex fan ports, the FH-04 lets you connect up to four independent fans using a 0.55 m cable, helping to improve overall system airflow while keeping installation space requirements low.

Advantages

The hub supports up to four independent fans and is compatible with both 3‑pin and 4‑pin fans. Each port includes PWM function so fan speeds can be adjusted individually, while the system only detects the speed of Fan 1. Its small footprint and included double-sided adhesive make the FH-04 easy to install and integrate into most chassis layouts.

Suitable for

• Expanding cooling capacity in desktop PC cases
• Managing multiple case or radiator fans from a single header
• Compact builds where space for additional fan controllers is limited

How to use

Mount the FH-04 inside the chassis using the included double-sided adhesive, or secure it in another convenient location. Connect the hub’s 20‑pin ATX connector to the appropriate motherboard or power source, then attach up to four fans to the 3‑pin Molex ports. Configure fan control via the motherboard or fan controller; note that only Fan 1 RPM will be reported to the system while PWM adjustments apply per port.

Recommendations

For reliable operation, place the hub in a location with minimal obstruction to airflow and avoid routing cables across high-temperature components. Verify motherboard or controller compatibility with the 20‑pin connection and ensure the combined power draw of connected fans does not exceed the supply limits.
