Advanced technology for cooling the world's fastest CPUs
If you're serious about high-performance computing and overclocking, you already know that
you've got to keep your PC's processor cool. In order to do this you need a CPU cooler that not
only outperforms your current heatsink, but also does it quietly.
The Hydro Series H70 has been designed to deliver exceptional levels of cooling performance, and
to provide significant headroom for overclocking your processor, quietly and reliably.
The Hydro Series H70 is an evolution of the award-winning Hydro Series H50, with several
significant upgrades that enable it to deliver even greater cooling performance. These upgrades
include a thicker 120mm radiator unit (50mm) with a higher heat-exchanging capacity, and a more
efficient, low-profile pump/cold-plate unit that can soak up more heat and provide even lower
CPU temperatures. The Hydro Series H70 also features two speed-switchable 120mm cooling fans
in a push-pull configuration to provide powerful cooling airflow at low noise levels.
The Hydro Series H70 is compatible with all current CPU socket designs, including Intel LGA775,
LGA1156 and LGA1366, and AMD Socket AM2 and Socket AM3.

  • Page 3 Lower weight and bulk – puts minimal stress on the motherboard and makes it easier to fit Compact cooling block – more flexible installs; doesn’t impede other components, such as RAM The Corsair Hydro H70 offers higher cooling performance, lower noise and better overall system reliability compared to competing premium CPU cooling solutions.
  • Page 4 There are two options for configuring the airflow of the Corsair Hydro Series H70 when you install it into your chassis. The approach recommended by Corsair is to install the fans so that they draw in cool air from outside the chassis. This ensures that the delta between the air temperature and the temperature of the radiator is maximized, which increases cooling performance according to Newton’s Law of Cooling.
