Corsair H70

When we first reviewed the H50 Corsair were still in the mind-set of sending their products out in plain boxes but that has all changed. Now we get a professional looking retail box with clear images and plenty of information on the product listed on the box sides. Inside we find the cooler sitting in a cardboard tray, each major component protected from the others. Corsair provide plenty of documentation with the H70, including guides on how to install the retention brackets for each CPU socket type. The Intel kit is shown above, supporting 775, 1156 and 1366 CPUs and an AM2/3 set is also supplied.

Moving on to the main components and the one which dominates the box is Corsairs new radiator. This is an aluminium unit and has the standard 120mm dimensions for height and width but thickness is a different matter as Corsair have gone for a 5cm model rather than the 2.5cm equivalent which is used on the H50. The main benefits of this radiator are a larger heat transfer area and the ability to hold a larger volume of the anti-fungal, anti-corrosive coolant.

Moving to the pump we find that Corsair have completely redesigned this part of the cooler, making it significantly smaller than the H50 design. The new low profile pump sits above a copper cold plate and through use of micro channel technology allows efficient flow in/out through the low permeability tubing (1/4" ID) at the side of the block. As well as pre-sealing the coolant within the system at the factory Corsair also apply a layer of thermal paste to the CPU plate, saving the user some time.

Two fans are supplied with the H70 and are 120x120x25mm models. These fans are rated for 1600-2000RPM operation and this can be selected by the user through installation of the two step down adapters which are bundled with the unit. Corsair rates the fans at 50.35-61.2 CFM, 1.8-2.3mm H20 static pressure (each) and 26-31.5dBA of noise per fan. Each fan has a 3-pin connector and Corsair supply a cable to power these off a single 3-pin motherboard connector.

Shown above is the H70 when fully assembled, Corsair recommend that the fans are installed in a push/pull configuration and that they are installed so that cold air is drawn into the radiator from the outside of the case, rather than through the motherboard chamber of a case.

Also shown are two comparison pictures, the first is a comparison to the H50, with the four noticeable differences being the radiator thickness (2.5 vs. 5cm), pump size, number of fans (1 vs. 2) and tube length with the H50 being slightly longer. In the second comparison picture we have the H70 sitting beside the Vantage which looks like it may have a 2nd fan however this is not the case; it is simply a fan housing to aid compatibility with compact cases.
