Pump Expansion Chamber (PEC)
The pumped version features TWO outlet ports and TWO inlet ports allowing two discrete loops on the same reservoir, pump, and radiator without the use of additional manifolds, “Y’s” or “T’s” which can decrease efficiency in the loop/s. As mentioned earlier it fits the D5 pump and will be available either with or without the pump for those who already own a D5.
The pump housing features a full 360 degree deep draw helix with an oversized (nearly double the stock D5) primary outlet that feeds an expansion chamber to decrease any pressure drop. The back of the housing is optimized for the dual bay upright mounting position so that water is spun up by a spiral structure that is humped (we buy it dinner first =) and ends in a very sharp edge at the inlet terminus which feeds water into the impeller at a decreased angle that lowers motor loading.
Although it obviously will not run two loops as well as it would one, it comes closer then you might think, and certainly closer then two loops created with “Y’s” or “T’s” or manifolds. It will outperform a single loop that feeds both a CPU and video card/s in cooling power because all components are getting cooler water—you’re not feeding preheated water from one component into the next component on the chain.
Users only wanting to run one loop can simply use the included plugs to cap off one pair of ports. The pumped version is a true two bay solution because all four ports face directly rearward. There is no need to use one or more bays above or bellow the reservoir to allow for turning radius on your tubing. Obviously the eight port standard is also a true two bay solution.
Stay tuned for more pictures/info and Release Dates...
