Thermalright has undoubtedly created a legendary heatsink with their Ultra Extreme. I am pleased to say that their new TRUE Black 120 is no exception and has thoroughly impressed me. Its performance was second to none on our toasty Q6600 test platform. Not only did it best all sixteen other heatsinks we have tested, it did so by a significant margin.
