Introduction

See that logo above? I had to manually upload it as part of this review instead of taking it from an older product review, which makes this one of a first set of two Watercool reviews on TechPowerUp—surprising considering there have nearly been 100 reviews in this category since I joined the team. Watercool, which might be better known as Heatkiller in some realms, is a small German outfit that is still growing to meet the needs of the DIY watercooling community. To give you a better idea of how small the outfit is, it deliberately does not send out product samples to larger media outfits since it would not be able to meet the production demands that would arise as a result. The company has added additional manufacturing over the past few months however, so be on the lookout for more Watercool coverage on TechPowerUp!


This review is of the thicker Heatkiller Rad 360-L, which, as the name suggests, is the 360 mm (triple 120) version. This series comes in 120/240/360/480 mm versions and is a completely new radiator lineup from Watercool, which otherwise used the round cylindrical tubes and straight fins in radiators models, including with the massive MORA and boxy HTSF lines from before. This article is meant to be read alongside our accompanying Heatkiller Rad 360-S review, which is a thinner radiator in the same 360 mm size. The two share a lot of common DNA, but are intended for different use cases. The Heatkiller Rad 360-L is 50 mm thick, which has it fall into the 50–60 mm thickness range that requires cases designed with custom watercooling in mind. As always, we begin the review with a look at the specifications below, but let's not forget to thank Watercool for sending review samples to TechPowerUp.
