EKWB Announces 420 and 560mm CoolStream Slim Radiators

After introducing 140mm and 280mm CoolStream slim radiators last month, EKWB is following it up with new 420 and 560mm versions. While the 140mm and 280mm fill the performance gap of existing CoolStream models, the two new additions bring significant performance bump considering their size. A 420mm radiator can fit 3 x 140mm fans on one side, while the 560mm can fit four 140mm fans on one side.

EKWB CoolStream SE Features

• Copper fins
• 90% copper tubing (H90)
• Brass chambers
• Aluminum/Steel housing
• FPI: 22
• Port threads: 2x G1/4″
• Fan compatibility: any standard size 140x140x25mm fan
• Fan mount thread type: UNC 6-32 thread tapping

Each radiator has 22 fins which the EKWB Vardar fans compliment well with its static pressure performance. Like the previous CoolStream models, the radiator uses 90% copper tubing with brass chambers and copper fins. Two G1/4-inch standard threads are available for connection, and the fan mount uses UNC 6-32 thread tapping. Unlike other radiators, the fan size is the same width as the radiator. Which means there is no overlap and it fits inside most cases, in comparison to other 420mm or 560mm radiators.
