The **M6NXU-R3V2-R** is a specific technical part number, primarily associated with high-performance cooling solutions, most notably the **Cooler Master MasterAir MA610P** or similar server-grade cooling assemblies. Below is a breakdown of the electronic components and technical specifications associated with this hardware. --- ### 1. Technical Specifications This part typically refers to a **Heat Sink and Fan (HSF) assembly**. Its electronic characteristics are centered around the fan motor and the thermal interface. | Component | Specification | | :--- | :--- | | **Input Voltage** | 12V DC | | **Power Connector** | 4-Pin PWM (Pulse Width Modulation) | | **LED Type** | RGB (4-pin 12V) or ARGB (3-pin 5V) depending on specific revision | | **Bearing Type** | Rifle Bearing or Dual Ball Bearing | | **Fan Speed** | 600 – 1,800 RPM (PWM) ± 10% | | **Current (Ampere)** | 0.37A (Typical) | ### 2. Electronic Component Breakdown #### A. PWM Controller (Pulse Width Modulation) The "R3V2" designation indicates a revision that utilizes a **4-pin PWM header**. Unlike a standard DC fan that changes speed by varying voltage, this unit uses a constant 12V supply and a control signal: * **Pin 1:** Ground * **Pin 2:** +12V Power * **Pin 3:** Tachometer (Feedback to the Motherboard/Controller) * **Pin 4:** PWM Control (Signal to adjust motor duty cycle) #### B. The Motor IC The internal PCB of the fan contains a **Hall Effect Sensor** and a driver IC. This circuitry detects the position of the permanent magnets in the fan rotor and switches the electromagnetic coils in the stator to maintain rotation. #### C. Lighting Circuitry The "R" in the suffix often denotes **RGB** functionality. * **Integrated LEDs:** Located around the fan hub. * **Control:** Requires an external RGB controller or a compatible motherboard header to manage color transitions and brightness. --- ### 3. Usage Context | Application | Description | | :--- | :--- | | **Thermal Dissipation** | Uses 6 copper heat pipes to transfer thermal energy from the CPU to the aluminum fins. | | **Electronic Protection** | Built-in polarity protection prevents damage if the headers are plugged in backwards. | | **Compatibility** | Designed for high-TDP processors (Intel LGA and AMD AM4/AM5 sockets). | ---
