Loving my i7-4790k! Immediately after installation with my nh-d14, Full load on all 4 cores at 4.4GHz turbo would push temperatures to 69 - 72C for short periods. Now after an apparrent settling-in period, similar utilization of the cores leads to max temparatures of around 58 - 62C.The thermal compound was probably somewhat sloppily applied, and has had time to rearrange itself, I'm thinking. And the weather is quite a bit hotter than when I built the system! So much better performance and no dealing with massive excess heat from an AMD system. No need to OC, and HT gives me some of the benefits of 8cores, as well. Money well spent.
