My noctua nh-d15 can't go under 60c (don't know what program comes closest to the real temps of a 8 core fx ) with a fx 8300 at 4.2ghz 1.368wolt (170-175watt) with 3x140mm be quiet pure wings 2 1000rpm fans a in a define r5
There are 2 distinct temperatures measured in those processors. Core temp (up to ~62c max) and Package temps (Up to ~90c max). If you have 60c Package temps that free versions of HW monitor shows. than you are running pretty cool.
Try using AOD (AMD Overdrive) program.
