The chaps over at EVGA have added a new product to their Hydro Copper Waterblock Series, which will expand the lineup to cool its first X58 motherboard, the EVGA X58 SLI. The X58 Hydro Copper Waterblock (200-CU-HC58-B1) features a sleek-modern look and is fully compatible with all three part numbers of the X58 SLI motherboard. EVGA is calling the engineering work behind this block an “E-Flow” design, which it claims capable of dropping CPU operating temperature down by as much as half. In testing, the block was able to keep the IOH around 26C. More specifically, the block features a high flow path design and will cover both the IOH and southbridge. Included in the package are both 1/2” and 3/8” fittings as well as some Artic Silver Ceramique thermal compound material. The new Hydro Copper waterblock is currently available directly from EVGA for $129.99.
