I don't believe that every test result is representative of actual results, in every situation. I have the U14S with my 6700k@4.5Ghz, for example, and temps never go over 65°C when running Prime95 no matter how long I run it. With the 212 EVO it would either run into the upper 70's OR you had to have the fan running full blast. My temp was with the fan at only about 70%.
I haven't used the Phanteks cooler on this system to compare it to, but what I can say is that the Noctua cooler uses a far superior fan bearing which is likely to last much longer, so yes, it's probably worth the extra money, but perhaps not in this case, for you. I'm skeptical of many performance reviews, because I know they tend NOT to knock companies that are a bit...
