I just bought the Rosewill Thor V2 for 100$ after rebate and the Gamer storm Assassin for $39+ shipping then installed them both. During hours of prime 95 I'm not even going above 60 and that's with the Thor V2 fans set on the lowest setting. I'm pretty happy with the purchases since before I was using a crappy case + stock cpu cooler and would hit 85c under load.
I went back down to 4.0 but was having trouble stabilizing still where my system randomly froze twice during web browsing + prime 95 so I watched a new youtube video where the guy took his to 4.0 so I used his settings while changing only my voltages a bit and I seem to have found a stable 4.0 since I haven't froze and prime95 has run perfectly fine for the last 2 hours.
My current new 4.0 stable settings are below, what can I do to hit 4.2 or do you think I should just throw in my hat and be happy with 4.0? It's definitely a major difference since I've run this thing at stock for the past 3-4 years and now my PC boots up really fast and applications load way faster.
