The Alphacool Core DDCzero Flat Reservoirs combine a compact reservoir with the powerful Alphacool DDCzero PWM pump. Thanks to their flat design, they are particularly well suited for small-form-factor systems. The series is available in various sizes, allowing flexible adaptation to different case layouts and cooling concepts. The base of the Core DDCzero Flat Reservoirs is made of durable acetal. The transparent top is manufactured from high-quality acrylic and provides an unobstructed view into the reservoir. The G1/4" connection threads are integrated directly into the robust acetal base. This avoids sensitive threads in the acrylic and ensures a stable and reliable connection. Five G1/4" ports provide numerous options for integrating the reservoir into the cooling loop. Inlet, outlet, filling and draining can be flexibly adapted to the tubing layout of the respective cooling system. The 200 variant is the largest model in the series and offers the highest filling volume. As a special feature, it can be equipped with up to two DDCzero pumps, making it suitable for larger or more demanding cooling loops. The integrated Alphacool DDCzero PWM pump is a compact and powerful circulation pump for PC water-cooling systems, datacenter systems and industrial applications. A robust ceramic shaft, combined with the durable plastic housing, ensures reliable and long-lasting operation. The pump provides strong performance and ensures a dependable coolant flow. Its speed can be flexibly adjusted across a wide control range to meet the individual requirements of the system. The Alphacool DDCzero PWM pump is connected to the motherboard or a suitable controller via a 4-pin fan connector. Compatibility The Alphacool DDCzero pump tops and reservoirs are exclusively compatible with the Alphacool Core DDCzero PWM pump. Standard DDC pumps cannot be used due to their larger dimensions.
