Alphacool Core DDCzero XS expansionskärl med pump (14848)

Water cooling enthusiasts building compact systems often struggle to find a pump-reservoir combo that fits tight spaces without sacrificing performance. The Alphacool Core DDCzero XS Reservoir with Pump solves that challenge, integrating a reliable DDCzero pump into a cube-shaped reservoir measuring just 62 mm per side. Its acetal housing and PMMA window offer durability and a clear view of the coolant, while the integrated top fill port simplifies maintenance. Whether you're assembling a small form factor PC or upgrading an existing loop, this unit delivers consistent flow and quiet operation.

Why choose it

This reservoir-pump unit is engineered for space-constrained builds, offering a compact footprint without compromising on cooling performance. The ceramic bearing ensures longevity and silent operation, while the fixed 2500 RPM speed provides a steady flow rate ideal for CPU and GPU blocks. The acetal and PMMA construction resists common coolants and provides a clean, professional look. With three G1/4" ports, you have flexible routing options, and the top fill port makes bleeding and topping up the loop straightforward.

Ideal use cases

• Small form factor (SFF) custom water cooling loops
• Compact gaming PCs where space is at a premium
• Upgrading existing loops with a reliable, low-noise pump
• Showcase builds where a clear reservoir window is desired

Good to know

The DDCzero pump is a cost-effective variant of the popular DDC platform, offering reliable performance at a lower price point. It operates at a fixed speed, which simplifies setup—no PWM control needed. The 3-pin fan connector plugs directly into a motherboard header or fan controller. The reservoir's small capacity means frequent top-ups may be needed in large loops, but it's ideal for compact systems. Mounting hardware is not included; use standard M4 screws and brackets compatible with the 62 mm cube dimensions.
