Founded in 2002, Thermalright has been a part of the computing world for nearly a decade. Throughout their presence in cooling market, Thermalright has not ceased to manufacture top-of-the-line cooling products for CPUs, GPUs and RAM - since the introduction of the first generation AMD Thunderbirds. Thermalright has been known for their absolute focus on performance, straying away from flashy plastic housings and bright lighting. Today, I will be reviewing the Thermalright HR-02, which can be used passively - without any fans. The benefit for some users of being able to run a passive heatsink is the absolute lack of noise. People who prefer no noise but still wish to run high end computer parts without the hassle of water cooling may have trouble finding heatsinks that are up to the task. The Thermalright HR-02 is specifically designed to perform passively, though it does have the ability to accept one or two fans. This review will contain a complete evaluation of the Thermalright HR-02's unboxing, appearance, construction and installation, specifications and features, followed by rigorous testing.
