Corsair H70 Review – versus Vantage & NH D14 @ 4.53ghz

The Corsair H70 arrives in a beautifully designed box, which immediately reminds us of the AX1200 and AX850 power supplies we recently reviewed. We really like these new Corsair designs.

The unit arrives well protected with the CPU head wrapped in protective plastic and a hard cover over it.

The kit contains a primary fitting instruction guide with sub-guides for each socket type.

The package contains backplates for both Intel and AMD as well as front mounted brackets for final fitting. All necessary mounting equipment for slot 775, 1156, 1366 and AM2/3 are included.

Corsair supply two 120mm fans which connect to each side of the radiator in a push/pull methodology. The H50 only had a single fan so airflow will be significantly improved with the H70. These are rated at 1,600-2,000rpm and this can be selected by use of the step down adapters which they supply (see above). Corsair rate the fans at 50.24-61.2 cfm operation and around 26-31.5dBa each. These run from 3 pin power connectors and Corsair also supply a Y cable to power them both from a single port on a motherboard.

Our radiator arrived in pretty good condition with only a few scuffs on each side which you can see in the images above. It didn't have any effect on the cooling prowess but it raised an eyebrow when we removed the unit from the box. This radiator is a new design as it is a 5cm thick unit compared to the old 2.5cm version which formed the basis for the H50. Obviously with double width this means there will be a larger heat transfer area. The liquid comes pre installed and contains anti fungal, anti corrosive coolant.

The total surface area of the cooling fins is significantly increased.

Above are images of the cooler before the fans were fitted, the radiator can be seen to be significantly thicker than the H50's. We noticed the tube length on the H70 is also shorter.

Corsair have completely redesigned the pump and it is much smaller than the H50 design. This new low profile design rests above a copper cold plate and Corsair are using micro channel technology to allow for efficient flow through the tubing. You will also notice that a layer of thermal paste is already applied from the factory, we used this in our testing today.

The Corsair H70 with both fans fitted – we will look at the installation on the next page.
