Details
The Alphacool Core DDCzero 3300-4800rpm PWM Pump is a compact, PWM-controlled circulation pump for custom PC water cooling, with a maximum flow rate of up to 220 L/h. Please note that, due to its unique design, it is only compatible with pump tops and reservoirs specifically designed for the DDCzero platform. It is also sold together with one, as the Core DDCzero Pumptop with Pump or the Flat Reservoir 90 with Pump.

How it is built
At its core, the pump features a durable ceramic shaft paired with a ferrite magnetic rotor, and the housing is constructed from plastic. The shaft is there for long-term durability, the rotor for reliable continuous operation. The pair is rated for up to 50,000 hours under 24/7 operation, providing an extended service life and exceptional reliability. Its lightweight design makes it an excellent solution for systems where installation space is limited.
Flow and speed control
Despite its small footprint, the pump provides a head of 1.42 meters, ensuring dependable coolant circulation for a wide range of cooling systems. PWM control allows the pump speed to be adjusted between the two ends of its range, balancing cooling performance, power consumption and noise levels to match system requirements. It is energy-efficient and quiet at the same time, with low power consumption and the noise level listed above. Power and speed control are handled through the one standard connector, with RPM monitoring via the same plug, allowing direct motherboard or fan controller integration without additional wiring.
Where it is used
The pump was engineered and designed for continuous operation in custom PCs, servers, server environments, data centers and industrial cooling applications. It delivers its flow while maintaining quiet performance, and is built for demanding environments including gaming PCs, workstations and enterprise servers.
Compatibility and what the loop needs
The package includes the pump without a top, so a DDCzero-specific pump top or reservoir has to be on hand before it can run. The manual's steps are short: install the O-ring, install the pump in the pump top, then connect the 4-pin PWM cable.
