Engineered in the USA

Introduction:

Named after the Epsilon Aurigae binary star system, the Epsilon™ series of waterblocks is a single slot, full cover liquid cooling solution 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 ATI® reference 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.

(*) Compatibility

  • Epsilon GTX295: nVidia® GTX295 reference board design P658 (single board)
  • Epsilon HD5970: ATI® Radeon HD5970 reference board design

How to check for compatibility with nVidia boards?

The nVidia® reference board number is usually printed on the back of the circuit board, in a code located below the nVidia logo, as can be seen below. This example shows a P891 board.
