Yes, however, Core temperatures are more important than Package temperature. Use Real Temp 3.7.
Regardless, There may be an issue with your case ventilation or cable management.
Just as you suspected, I agree that it would be better to back it down to 4.6. This should allow you to reduce Vcore to about 1.210, which should in turn drop your rendering temperatures by 6 to 8C. If you then repeat Prime 95 v26.6 Small FFT's, I think you'll see the Core temperatures drop by about 8 to 10C.
