The newest iteration of Thermalright's flagship cooler offers better RAM clearance (45mm) than previous models. In terms of overall dimensions, the Macho Rev.C Plus is 140 x 102 x 158 mm and features six 6mm heat pipes. Passive cooling is still an option according to Thermalright, although the Taiwanese company makes no mention of max TDP. When in doubt, go with the larger Le Grand Macho which handles 65W CPUs for sure.
