Chassis Fan Speed Regulation Module for 1 to 4 Pin Fans Function and benefits Automatic temperature based speed control: adjusts fan speed in response to temperature to maintain safe operating temperatures while reducing noise and power consumption. Supports multiple fans: connects 1 to 4 fans and provides coordinated speed regulation for efficient cooling in compact spaces. Flexible voltage options: designed for DC 12V or 24V systems, enabling use in a wide range of builds and enclosures. Simple integration: compact form factor for easy installation into PC cases, server enclosures, or other equipment without complex wiring. Key specifications Fan connections: 1 to 4 pin fans (1, 2, 3, or 4 cable configurations) Input voltage: DC 12V or DC 24V Maximum current: up to 4A Temperature controlled: speed adjusts automatically based on temperature readings Design and compatibility Compact and unobtrusive form factor suitable for tight chassis spaces Built to provide reliable operation in standard computer and enclosure configurations Keeps cooling performance consistent while minimizing noise during routine operation Performance and reliability Temperaturebased regulation provides a practical balance between cooling efficiency and acoustic comfort Suitable for environments with fluctuating thermal loads, helping maintain stable temperatures across multiple fans Suitable for everyday use in professional and enthusiast builds where predictable cooling behavior is desired Applications and use scenarios Desktop PC or gaming rig: achieve quiet operation during light use and maintain adequate cooling under load by automatically adjusting fan speeds Home server or NAS with multiple fans: synchronize and regulate cooling across several fans to optimize energy use and reduce noise Enclosed equipment such as 3D printer setups or small industrial enclosures: maintain stable temperatures with minimal manual intervention while keeping noise levels down
