Following up on the review of the Alphacool XT45 Triple 180 radiator, let’s now take a look at EK’s offering. They have, over the past 2 years, revised their entire radiator lineup beginning with the Coolstream PE (Performance Edition) for the 120 mm fan size and added 2 more for the 120, 1 for the 140 and 1 for the 180 mm fan size. The Coolstream WE (Wide Edition) is their attempt to get into the 180 mm radiator market, and getting ready for a time when 180 mm fans and radiators will gain more traction just as how we have moved from 80/92 mm to 120 mm and now to 140 mm as well. At this time though, aside from use as an external radiator, the few cases that support 180 mm size radiators generally have a thickness limit of 55-60 mm total (rad + fan). As such, EK wanted to target this compatibility boundary condition and thanks to Derick we can examine how well they have done.

Let’s begin by taking a look at the specs from the product page:

As with the other new radiator designs from EK, the WE adopts a boxy design with a removable housing for modders to be able to paint or apply a different finish. By default, the radiator core which is copper and brass comes with black paint on the visible areas and the stainless steel house has a matte finish as well. As a result of the floating core design inside the housing, the EK WE radiators are longer than average and this is no exception coming in at 40 mm over the length of 3×180 mm fans in a line so please account for system compatibility. EK has a technical drawing as well for reference to assist with this. The core design seems like to their EK-Coolstream PE with 19 splitter fins, 2 ports and the floating core rated to 1 bar of pressure. So be careful if you plan to use air leak tests using pressurized air. As with everything  EK, this also carries a limited 2-year manufacturer warranty including this one. Let’s carry on to the next page now for a good look at the radiator.
