The Alphacool Core DDCzero Pump Top combines an exceptionally compact design with the powerful Alphacool DDCzero PWM pump. Thanks to its small dimensions, the pump-top combination is ideal for small-form-factor systems and other water-cooling systems with severely limited installation space. The base and top are made entirely of durable acetal. The G1/4" connection threads are also integrated directly into the robust material, ensuring a stable and reliable connection for the installed fittings. Three G1/4" ports enable flexible integration into the cooling loop. This allows the compact unit to be adapted to different tubing layouts and system configurations. The Core DDCzero Pump Top combines the pump and top in one space-saving unit, making it suitable for small cases as well as densely populated PC, server and industrial systems. The enclosed, linear design integrates seamlessly into the design language of the Alphacool Core series. 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 offers high delivery performance and ensures a reliable coolant flow. Its speed can be flexibly adjusted across a wide control range to meet the specific requirements of the system. The Alphacool DDCzero PWM pump is connected to the motherboard or a suitable controller via a 4-pin fan connector. This connector supplies power to the pump, enables PWM control and transmits the speed signal. PWM control allows the pump performance to be adjusted specifically to the current system load. 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.
