Product information

Description

Gelid FC‑MC01B‑B is a compact fan speed controller designed to reduce fan RPM and acoustic noise by providing a stable 5 V output from a 12 V input. The unit is housed in a black enclosure measuring 62 × 19 × 25 mm and is rated to supply up to 700 mA, making it suitable for a single 3‑pin or 4‑pin fan that accepts a 5 V feed. The device provides a simple hardware solution to lower cooling fan speed when full voltage is not required, helping to balance airflow and noise in PC cases or other electronics cooling applications.

Advantages

The controller offers a straightforward means to decrease fan speed without modifying motherboard settings or firmware. Its fixed 5 V regulated output delivers consistent reduced RPM under varying input conditions. The small, black enclosure is space‑efficient and easy to integrate into tight spaces inside computer cases or equipment racks. Rated current protection up to 700 mA ensures compatibility with many single fans used in consumer PCs and electronics cooling.

Suitable for

  • Reducing noise from a single 3‑pin or 4‑pin case fan that accepts a 5 V supply
  • Lowering RPM of fans in compact PC builds or HTPCs
  • Quieting fans in small electronics enclosures or network equipment
  • Testing fan behaviour at reduced voltage for diagnostics

Key specifications

  • Input voltage: 12 V DC
  • Output voltage: regulated 5 V DC
  • Maximum output current: 700 mA
  • Supported fan types: single 3‑pin or 4‑pin fans that accept a 5 V feed
  • Enclosure colour and dimensions: black, 62 × 19 × 25 mm

How to use

Connect the controller between the 12 V supply and the fan’s power lead so the fan receives the regulated 5 V output. Ensure the fan’s current draw does not exceed 700 mA. The unit provides a fixed reduced voltage output; no software configuration is required. For 4‑pin fans, leave the PWM control pin connected to the motherboard or controller as needed, but power should be routed through the FC‑MC01B‑B to obtain the lowered supply voltage.

Usage recommendations

Verify fan specifications and measure current draw before installation. Use the controller only with fans that operate reliably at 5 V and within the 700 mA limit. Avoid exceeding the rated current to prevent overheating. Install the unit in a location with adequate airflow and secure connections to prevent accidental disconnection during operation.
