Your CPU Temperature is a little bit high for only running a 6 Core. Try to get better case airflow or put a fan over the Voltage Regulator heatsink. I am not sure what CPU Cooler you are using but if it is an all in one water cooler then you definitely need a fan over the VRM's to bring the CPU temp down.
The main temperature you want to go by for the CPU is Package Temperature. Accoring to HWMonitor you're only hitting 51C during OCCT Stress Testing so you have a lot of headroom to Overclock.
