No problems encountered in new system. Was able to get a decent OC without unlocking power limits: Single x 4.9 GHz / 2,3,4 x 4.8 GHz / 5,All x 4.7 GHz. Vcore max: 1.264v. CPU cooler used was the Noctua D15. Temperatures never exceeded 81°C in full AVX loads (tested with AIDA64) and 70°C in full non-AVX and gaming loads (tested with Prime95 26.6 and FFXV etc.).
