The **M6DPP-CA2N-R** is a specific part number typically associated with high-performance cooling solutions, most commonly identified as a component of the **Cooler Master MasterLiquid** series (specifically related to the pump/block assembly for All-in-One liquid coolers). --- ### 1. Component Overview This part represents the core "Pump-Block" unit. In a liquid cooling system, this is the electronic heart that manages heat transfer from the CPU to the liquid coolant. | Feature | Specification Details | | :--- | :--- | | **Component Type** | Dual Chamber Pump Assembly | | **Connection** | 3-Pin or 4-Pin PWM Connector | | **Lighting** | Addressable Gen 2 RGB (ARGB) | | **Material** | Copper Base (Cold Plate) / PPS-Glass Fiber Housing | | **Operating Voltage** | 12V DC (Pump) / 5V DC (LEDs) | --- ### 2. Key Electronic & Mechanical Parts #### A. The Dual Chamber Pump The internal electronics drive a motor that separates the incoming "cold" liquid from the outgoing "hot" liquid. * **Motor:** Typically a 3-phase motor with a silent driver IC to minimize magnetic noise. * **Impeller:** Designed to maximize water pressure and flow rate while maintaining low RPMs. #### B. ARGB Lighting System The "CA2N" designation often refers to the specific lighting controller integration. * **LED Type:** Addressable RGB LEDs allow each diode to be controlled individually. * **Interface:** Standard 3-pin 5V ARGB header. * **Controller Compatibility:** Compatible with software like MasterPlus+ or motherboard ecosystems (ASUS Aura, MSI Mystic Light). #### C. Cold Plate (Thermal Interface) The electronic efficiency of the unit depends on the **Microchannel Cold Plate**. * **Function:** Increases the surface area between the copper and the coolant. * **Sensor Integration:** Some variants include an internal thermistor to report liquid temperature to the BIOS. --- ### 3. Wiring Configuration | Wire Color/Type | Function | Destination | | :--- | :--- | :--- | | **Black (3-pin)** | Pump Power/Tachometer | Motherboard AIO_PUMP or CPU_FAN header | | **3-pin (5V/D/G)** | ARGB Signal | Motherboard ARGB Header or Hub | --- ### 4. Technical Advantages * **PPS (Polyphenylene Sulfide) Housing:** Provides resistance to chemicals and moisture, ensuring the electronics inside the pump remain dry. * **Tri-Phase Motor:** Reduces power consumption and vibration compared to standard single-phase motors. * **Ceramic Bearing:** Used in the pump shaft for longevity and resistance to corrosion. ---
