The Epsilon™ water-block is a single slot, liquid cooling solution for nVidia® reference design (P658*) GeForce™ GTX295 graphics cards. This "full cover" waterblock cools the GPU, Voltage Regulators, I/O chip, memory modules, and other critical components.
The Epsilon™ water-block offers superior thermal performance at the GPU level thanks to an embedded thin-pin matrix located directly above the GPU area. Flow restriction is moderate by design in order to take into account multiple water-blocks in the same loop.
The base plate is made of chrome plated electrolytic copper, as opposed to commonly used nickel plating which is yellowish, and the top is machined in clear polycarbonate material. The advantage of polycarbonate over widely used acrylic is that it is virtually impervious to cracking.
High thermal conductivity grease pads are pre-applied in the memory and mosfet areas for user convenience. Short barb fittings are included for either 3/8" or 1/2" tubing and are compatible with quad SLI setups
