Changes have been made to the block / pump assembly as well. The new H70 features dimensions of 30mm height and 74mm diameter. The older H50 measures 55mm in height and 70mm across. Aside from this, the two blocks are very similar. There is a single 3-pin power cable running from the pump that measures 12-13 inches long.
The base of the water block is solid copper and ships with thermal interface material pre-installed. We will leave this in place for our testing here today.
As Zahn pointed out in his H50 review, these units are rebranded Asetek coolers and the H70 is seemingly the same, matching up identically to the Asetek 570LC seen here. This isn't a bad thing as many manufacturers rebrand everything from CPU coolers and power supplies to gaming peripherals like keyboards and mice, but it's at least worth pointing out.
The two 120mm fans both spin at 2000 RPM and produce 61.2 CFM of air at 31.5 dBA. When utilizing the included in-line resistors, these numbers drop to 1600 RPM, 50.35 CFM at 26 dBA.
Let's move ahead and check out the installation process.
