Originally built this pc back in 2013, always ran it at stock speeds. Next let me say, I don't have this much in this PC. I had most of these parts since 2013 or before. I got an itch to upgrade, but didn't really see a point in a new CPU, MB, and Ram when I could just o/c the hell out of this one. I also wanted to work on the look of it as now I work from home and will see it all the time. So I bought a new case a few months back, just got the Asiahorse Solar Eclipse (4) case fans, and the CRYORIG H7 cooler. I did have a Cooler Master Hyper 212 EVO which would have been fine, but I wanted one that I though looked better, on the plus side the H7 cools better. When I started working from home back in March 2017, I wanted a bigger monitor. My pick was the LG -34UM67 34" ultrawide @ 75hz. I had a Hanns-G 28' that I now use for my work computer. Anyway, this has breathed new life into the old boy, as it seems to scream at 4.5ghz, topping out at 67c running prime for 2 hrs. When I game on this, it usually does't top 60c, usually about 55c-58c. I was hoping to get a Rx 580 or the newer Vega 56 cards but due to mining, I got tired of waiting and pulled the trigger on this ASUS GTX 1060 3gb card. Anyway is was a fun little revamp of an older machine.
