Corsair is expected to introduce the Hydro H50 all-in-one CPU watercooler next week. The new cooler looks similar to the H50, but features a twice as thick radiator, two dual-speed 120mm fans and a new copper surface that integrates directly into the pump. According to Corsair's internal testing, the H70 should deliver temperatures that are around 13°C lower than the H50 on an overclocked Intel Core i7 920 @ 3.8GHz with 1.34V.
The manufacturer has gone back to the drawing board with this new model and seems to have rethought almost every component. The radiator is twice as thick as the H50's, which will provide a larger surface area and allow for much better heat dissipation. This is now combined with two dual-speed 120mm fans, arranged in a push-pull configuration, forcing air across the cooling-fins. The increased airflow over a single fan should keep temperatures suitably low, while the lower speed-setting will allow for quiet operation.
The cooling block has also been redesigned and features a new copper surface that integrates directly into the pump. Coolant channels in the plate then draw heat away more efficiently than the old design, notes Corsair. Along with a new pump design, this means that the CPU-block on the H70 is much smaller than its predecessor's. The more compact pump-assembly should allow plenty of clearance around the CPU socket for any other large components.
Official pricing is unknown, but some shops offer it for preorder for around $110.
