TW D5  PWM Pump
Details

TW D5  PWM Pump Motor is a genuine high-performance D5 water pump with PWM speed control via the motherboard or a dedicated fan/pump controller.

PWM control allows for automatic pump speed regulation depending on your CPU temperature. Full performance on demand or whisper-quiet operation in idle mode!

Designed for PC and other electronics water cooling systems, the D5 pump utilizes an electronically commutated spherical motor. This design features a single moving part—a spherically shaped rotor—suspended on an ultra-hard, wear-resistant ceramic bearing.

The magnetic rotor self-aligns perfectly on the ceramic bearing, ensuring durability and efficient performance. All fluid-contact components are corrosion-resistant, contributing to the pump’s exceptionally long lifespan and reliable operation.
