The controller is designed to manage the speed of all standard fourwire chassis fans and CPU fans. It combines manual speed control with automatic temperaturebased speed control, providing a performance cooling accessory that fits a wide range of systems. Key benefits Simplified control: integrates manual speed adjustment with automatic temperaturebased speed management for reliable, hassle cooling. Safe operation: monitors each connected fan channel and provides audible and visual alerts if a fan fails, using a buzzerenabled alarm that clears automatically when the fan resumes normal operation. Temperaturedriven performance: outputs at minimum speed when the temperature is below the set minimum threshold and at full speed when the temperature reaches the maximum threshold, helping balance cooling and noise. Quality and durability: undergoes strict quality control and testing to ensure stable longterm operation under diverse environmental conditions. Durable construction: manufactured with quality materials, enabling accurate temperature setting and precise control, with easy maintenance and extended service life. Specifications and features Compatible with standard fourwire chassis fans and CPU fans Manual speed control plus automatic temperature control Audible and visual alarm for fanchannel failures (works with the buzzer) Alarm clears automatically when the affected fan resumes normal operation Precise temperature setting for reliable speed regulation Designed for longterm, stable performance in various environments Practical use scenarios Gaming PC or performance workstation: dynamic cooling control to maintain temperatures while balancing noise levels during heavy workloads. Small form factor or quiet PC builds: use the automatic temperaturebased control to keep system temperatures in check with minimal fan noise. Server or workstation deployments: continuous fan monitoring with audible/visual alerts helps identify cooling issues quickly, reducing downtime and potential hardware risk.
