Thanks. I had a large tower heatsink (Thermaltake Contac 30) on my old Phenom II X6 OC'ed to 3.7 GHz, and I believe it never reached 60º. I was surprised the 6700k without OC (4 GHz) hit 62 with an Arctic Freezer 13. Case is different though, I used an Antec 902 v3 before (very airy) and now a Fractal Design Define R4 (sound dampening, less airflow apparently).62°C is not that much. I'd start worrying once you go beyond 80°C.
