The Alphacool DDCzero is a compact and powerful circulation pump designed for use in PC water-cooling systems, datacenter systems, and industrial applications.
It ensures a reliable coolant supply while maintaining low power consumption. The pump speed can be monitored and controlled via a PWM signal using the 4-pin fan connector.

Features
The DDCzero was developed for reliable and long-lasting continuous operation. Inside, a robust ceramic shaft works in combination with a rotor made of ferrite magnetic material.
• Compact design - Ideal for SFF
• Speed range control of the pump via PWM
• High-performance with high flow rate

Thanks to its compact dimensions and low weight, the pump can also be installed in systems with limited space. Both the pump housing and the pump cover are made of durable plastic.
This makes it particularly suitable for server, datacenter, and industrial applications where high reliability and a long service life are required.

Performance
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.
Despite its compact design, the pump operates efficiently and is optimized for smooth and quiet operation.

Power Supply and Control
The Alphacool DDCzero is connected to the motherboard or a suitable controller via a 4-pin fan connector.
This connector supplies power to the pump, enables PWM speed control, and transmits the speed signal.

Areas of Application
The Alphacool DDCzero is suitable for a wide range of cooling systems. Thanks to its compact design, the pump can be flexibly integrated into various cooling and control concepts.

Compatibility
Due to the special design of the Alphacool Core DDCzero PWM pump, it is only compatible with pump tops and reservoirs specifically developed for the DDCzero.
