Alphacool Core DDCzero Pumptop with Pump (14566)

The Alphacool Core DDCzero Pumptop with Pump is a compact acetal pump top with the DDCzero PWM pump integrated and three G1/4 ports. The included bracket mounts it directly to any standard 120mm fan or radiator location.

Properties

• Pump: DDCzero PWM, 3,000 to 4,800 RPM
• Ports: 3x G1/4
• Maximum flow rate: 220 L/h
• Maximum head pressure: 1.4 meters
• Material: acetal, base and top

Pump and top in one

The unit combines the pump with a durable pump top to create a space-saving, high-performance solution for custom liquid cooling systems. It was designed for, and is ideal for, small form factor PCs, workstations, servers and industrial applications, where it delivers reliable coolant circulation while minimizing the space required inside the system. Whether you're building a compact gaming PC or a professional liquid-cooled workstation, it provides dependable performance in an exceptionally compact package.

Housing and ports

Constructed entirely from acetal, an all-acetal construction, both the base and top provide exceptional strength and long-term reliability. All of the G1/4 threaded ports are machined directly into the housing, with the threads creating secure, leak-resistant connections while allowing flexible tubing layouts. Three ports keep the loop configuration open, enough to accommodate a wide variety of cooling loop configurations.

Pump

At the heart of the unit is the PWM-controlled pump, delivering up to the flow and head pressure listed above. PWM speed control allows operation between the ends of its adjustable operating range, enabling users to optimize the balance between cooling performance, power consumption and noise levels. The ceramic shaft and durable construction ensure dependable long-term use in gaming systems, workstations, enterprise servers and industrial cooling.

Mounting

The pump top features a clean, minimalist design that integrates seamlessly with the Core series while maximizing installation flexibility. The package includes the Core Universal Mounting Kit with its mounting hardware, which lets the pump top mount on a fan or radiator position. It also supports both standard (straight) and 90° rotated mounting positions, making it easy to optimize tubing routes in compact, space-constrained installations or densely populated systems. Alphacool's manual says to install the mounting bracket with the screws (4x M3x8mm) that hold the cover in place.

What the loop needs

A loop uses two of the ports, one in and one out, so the pump top takes two G1/4 fittings. The third takes the plug in the box. The pump runs from a 4-Pin PWM cable. Alphacool's data for this kit gives 3,000 to 4,800 RPM, while the box list names the pump as the Core DDCzero 3300-4800rpm PWM Pump, which we also stock on its own.
