New CPU as well. My previous 2700K did 5.0ghz with less than 1.4v ... now I need at least 1.43v to get stable but temps are a bit on the high side for me, hitting mid 80's at hours long Prime loading and with 20C ambients. Before, with 1.39v, I rarely hit 75C, even with higher ambients. It's amazing what a few voltage ticks will do.
Later, I'll get rid of my modded H100 (high pressure mount) and either get a custom loop or one of the better Rasa kits.
What are you cooling your 5ghz machine with?
