The Wraith should be more than enough. I've seen people use it on the much hotter FX6000(can't remember which) to OC somewhere at 4,5 iirc. The FX were already rated 125watt, right out of the box. The OC probably push it to near 150watts level. Yet, somehow the Wraith sustain it at 80C tops. Even doing full speed most of the time, it still heard as a mere whisper. In fact, the Seasonic's fan he used were louder and more audible than the Wraith.
That said, I wanted this APU happened 3 months ago. I've already purchased 3 sets of G4400 + GT1030 + 2x2gb DDR4 + the cheapest h110 I could found which happens to be a foxconn's for my cyber cafe. fml
