Product information

Description

EK Water Blocks EK-Loop DDC 4.1 PWM Motor 12V is a compact DDC-series pump designed for custom PC water cooling loops. It operates on a 12V supply and includes PWM speed control for precise regulation of flow. The pump is intended for integration into CPU and GPU cooling circuits and small reservoirs, providing stable circulation and predictable performance across varying load conditions.

Advantages

The compact form factor simplifies installation in confined spaces while maintaining the hydraulic characteristics of a DDC-series pump. PWM control enables automatic adjustment of pump speed from the motherboard or a dedicated controller, allowing balance between cooling performance and noise. The 12V operation ensures compatibility with standard PC power systems and common fan headers that provide PWM signals.

Suitable for

  • Custom CPU water cooling loops
  • GPU and mixed-component water cooling circuits
  • Small or compact reservoir setups
  • Systems requiring PWM-based pump speed control

Key specifications

  • Form factor: compact DDC-series pump design suitable for tight enclosures
  • Power supply: 12V operation compatible with PC power systems
  • Control method: PWM (pulse-width modulation) for speed regulation
  • Typical application: circulation in custom liquid cooling loops for CPUs and GPUs

How to use

Mount the pump securely within the loop or on an appropriate bracket, ensuring correct inlet and outlet orientation according to your loop layout. Connect the 12V power and PWM control cable to a compatible motherboard header or controller that provides PWM signals. Prime the loop and fill with appropriate coolant, then run leak tests at low speeds before increasing to normal operating speeds. Adjust PWM duty cycle or fan curve in firmware or controller software to achieve the desired balance between flow rate and noise.

Usage recommendations

Use approved water-coolant solutions and maintain regular loop maintenance including checking fittings, coolant level, and cleaning to prevent debris accumulation. Avoid running the pump dry. For quieter operation, configure PWM curves to reduce speed at low thermal loads while ensuring sufficient flow for heat transfer under load.
