AMD Phenom II X42 TWKR Black Edition is not a CPU that will see the light of the day as a retail part [for now]. TWKR processors are speed binned Phenoms that AMD will use to get feedback from system integrators and respectable overclockers. Think of them as Phenom II 955 CPUs that can really go the distance. These high-leakage processors aren't meant to be used with air-cooling at all. Liquid is also doubtful, since putting 1.5-1.8V through 110A rail results in power consumption and dissipation of 165-198W and beyond. AMD states that these CPUs should be used with phase change or LN2 cooling only, as they are "the best of breed".
