Also, another core component of any water cooling, the radiator, there is of EKWB in various designs which - come now, the newly added Coolstream-CE models. These are very similar to Cool Stream PE models, so also have a medium strength, however, are designed for 140-mm fan. They once again combine high-quality workmanship, performance and design. Matt black and a very straightforward design with little rounded elements ensures a subtly luxurious look. The thickness of 45 mm allows together with the larger surface area, which is caused by the use of 140-mm fans, a brutal cooling capacity - and the passive as well as active, thanks to the fin density of 16 FPI.

Other qualities are hidden mainly in detail. This is already visible when looking at the scale: 1.59 kg, this 420 version proposes to beech, which is due to the very generous use of copper for the fins and the tubes. By contrast, the atria are made of brass and aluminum and steel - at every point so that each ideal material was used.

The fin design was optimal heat dissipation optimized with 140-mm fans, so it offers the radiator both for passive mode or slow speeds in Silent systems, as well as for high speeds in performance systems. With its enormous surface through the mounting possibility for all three 140-mm fans, this version offers a very high cooling capacity and can even cool extensive systems.

The integration into the cycle is carried out with two G1 / 4-inch threads, which are provided for maximum connectivity compatibility with preloaded extenders. The required connections are not supplied. There are, however, at the required 5-mm and 30-mm screws that are used to install the required fan on the radiator as well as for installation of Radis in the housing.
