The Alphacool VPP655 Variable Speed Pump - Bare Bones Single Edition is just the pump. Why buy a full D5 / MCP655 Series pump when you can just get the guts of the unit alone. Fits directly into bay reservoirs made for D5 , MCP655 Series and this pump is ideal for PC and other electronics water cooling. The DC pump is equipped with an electronically commutated spherical motor. In a pump with a spherical motor the only moving part is a spherically shaped rotor which in this pump is held in place by a bearing ball made of ultra-hard and wear-resistant ceramic. The spherical bearing of the rotor offers many advantages: For example an increase of bearing play is impossible due to the design, allowing the pump to run quietly and smoothly over its whole lifespan. A separate magnetic shielding of the pump is not needed.
The ball motor design allows efficient operation of the pump in combination with excellent performance. The pump can simply be connected to a 12V Molex connector of the system PSU.

The special feature of this model is the fact that only the pump core itself is shipped. Why pay more for all the things you won't need when using this pump with a third-party pump top? Another feature is the ability to be adjusted in five speed settings.
