Package description: With four direct mount copper heatpipes, software controllable RGB lighting, and a two position fan. It is the ultimate in a stock CPU coolers that we have come across in memory. The Prism served us very well in our AMD Precision Boost 2 and Wraith Prism Deep Dive article, which took place on an open test bench, which of course showed it in the best light possible. Let's now take that same cooler and put it on our HSF/AIO test system, which of course is more a "worst" case possible scenario, and see how it does. We are likely putting more heat to it than it will likely ever see in a real 2700X configuration, but we do separate the wheat from the chaff.
