This isn't exactly answering your question but if I were you, I would not purchase the FX8350 at this time in the year.
Currently AMD's new CPU line is coming out next year and will not be compatible with the AM3+ motherboards which the 8350 uses. AMD Zen looks very promising so it is work waiting for it to come our early next year.
I am currently running a system with an 8350 and use a corsair H75 (single 140mm radiator, i think, look it up), and I get temps from 35C at idle and 50-65C at load with 60% fan speed.
AMD's chips are known to be a bit extra hot but in my experience they don't go above 80C which is what I consider to be "too hot".
Hope this helps!
