Epsilon-HD5970AC

Introduction

Named after the Epsilon™ Aurigae binary star system, the Epsilon™ series of waterblocks are single slot, full cover liquid cooling solutions for dual GPU graphic cards. "Full cover" means that the waterblock cools both GPU's, Voltage Regulators, I/O chip, memory modules, and other critical components.

Available Models:

• The Epsilon™ GTX295, for nVidia reference design (P658*) GeForce™ GTX295 graphics cards, is available with either clear polycarbonate or black acetal housing.
• The Epsilon™ HD5970, for ATIreference design Radeon™ HD5970 graphics cards, is available with black acetal housing, and features a custom high performance black-anodized aluminum back-plate
  

Superior Performance
The Epsilon™ waterblock offers superior thermal performance at the GPU level thanks to an embedded thin-pin matrix located directly above the GPU areas. Flow restriction is moderate by design in order to take into account multiple water-blocks in the same loop.

Superior convenience for the user
High thermal conductivity grease pads are pre-applied in the memory and mosfet areas for user convenience. Inlet and outlet ports are G1/4 compatible and spaced to accomodate large compression fittings. Short fittings are available for quad SLI setups.

Superior quality
The CNC machined copper base is chrome plated for a durable and bright finish. Stainless steel standoffs are used to guaranty safe and reliable mounts to the PCB.

During operations: the flow path is carefully engineered to accelerate the coolant at the pin matrix level

The 0.6x0.6mm thin pin matrix machined over the GPU areas lowers thermal resistance, and allows superior performance even at reduced flow rates
