Watercool Heatkiller Radiator Copper 420-S Stainless Steel (420 x 30mm)

Watercool have now expanded the high-quality radiators of the HEATKILLER RAD series to include 280 and 420 mm versions. We use the popular slim format (S) with a height of 30 mm. In addition to the optimized performance, the radiators are characterized by their compact dimensions and the high-quality workmanship typical of Watercool.

Running a push-pull fan configuration? Heatkiller radiators come with fan screws for one side only. Additional screws are available here.

Finishing and quality control in Germany

In collaboration with a well-known manufacturer from Asia, we have succeeded in creating a powerful mesh radiator with a unique look. The cooling cores are manufactured strictly according to our specifications. The radiator housing is produced directly on site in Waren, meaning that the finishing and quality control ultimately take place in Germany.
 

High cooling performance across the entire speed range

The aim of the development was to produce competitive radiators with a wide performance range. Accordingly, the HEATKILLER RAD already shows very good cooling performance with slowly rotating fans, which scales excellently with increasing speed. For maximum cooling performance, the HEATKILLER RAD can of course also be used in push/pull operation.
 

The best raw materials in use

Only high-quality raw materials are used as the basis for the HEATKILLER RAD. The pre-chamber and channels are made of brass, the cooling fins of copper. Depending on the design, the side parts are lasered from 1mm thick sheet steel or stainless steel and then brushed or powder-coated in black or white. The front sides are made of brushed stainless steel and contribute significantly to the exclusive look of our HEATKILLER RAD.
 

Easy integration into the cooling circuit

The connection to the circuit is made using two standard G1/4 inch threads. The connections required for this are not included in the scope of delivery. The manufactured threaded holes ensure easy screwing in and high strength. The small width of only 120mm ensures maximum flexibility.
