The 920 at 5.0Ghz is only one degree better than the 620? The 620 is only 60 bucks, if this is a legit review I think I might pick one up to replace my crappy CNPS 9900 LED that I can't even go over 1.2v @ 3.7Ghz with.
 
Solution
yes they differ only a few degrees only if the default and overclock state of almost the same, although still below 1 degree Noctua D14
