After reviewing several CPU air coolers, it is time we to test the top-shelf liquid cooling solution from Corsair: the H70. It is a complete sealed system, with easy installation and no maintenance. Let’s see if it is really worthwhile picking this system over high-end air coolers.

Traditionally, water coolers are sold as individual components: you have to buy a radiator, block (or blocks, if you want to cool other parts othar than the CPU, like the GPU and the chipset), hoses, pump and reservoir. This kind of system is obviously targeted to the ultra-enthusiast user, since installing and setting up the system is not that easy. Some time ago, however, manufacturers started selling sealed systems, where the product comes preassembled and installation is almost as easy as regular air cooler. The H70 is one of these products.

The H70 box is big, made of hard card paper, as you can see in Figure 1.

In Figure 2, you can check the content of the box: the radiator/block system, two 120 mm fans, manual, and hardware installation parts. As you can see, the radiator, hoses and block are preassembled and sealed, which means the cooling fluid comes already inside the system and there is no need for maintenance.
