Overview 

The MH PWM Fan Controller is a versatile device designed to efficiently manage PWM (Pulse Width Modulation) fans, offering precise speed control to optimize cooling performance while minimizing noise. It supports multiple 4-pin PWM fans, allowing users to connect several fans to a single hub, making it ideal for PCs, servers, or custom cooling setups. Many models include built-in temperature sensors, enabling automatic fan speed adjustments based on real-time thermal data for hands-free operation. Users can also switch to manual mode to set fixed RPMs for full control over cooling and acoustics. Advanced versions feature an LCD or OLED display for monitoring fan speeds

Features

• PWM Fan Support – Compatible with 4-pin PWM fans for precise speed control.
• Multi-Fan Hub – Controls multiple fans (often 4–8) from a single controller.
• Thermal Auto Mode – Adjusts fan speed automatically using temperature probes (included in some models).
• Manual Speed Control – Allows fixed RPM settings for custom cooling/noise levels.
• LCD/OLED Display (on some models) – Shows real-time fan speeds and temps.
• Software Control – Advanced models support USB connectivity for PC-based tuning.
• Wide Compatibility – Works with 12V PWM fans (standard for PCs & servers).
• Low-Noise Optimization – Smart fan curves reduce unnecessary noise.
• SATA/Molex Power – Draws power directly from the PSU for stable operation.
