Thanks for the reassurance! Alright, guess I don't need to get worked up after all haha.
As for cooler, Xigmatek Gaia SD1283, grabbed it for $19 off Amazon. Instead of stock fan, went with 2 Yate Loon D12SH-12 in push-pull. TIM is Arctic Silver 5. HWMonitor states max cpu temperature as 25 C during Prime95.
So far, I am happy with the FX-4170 at stock speeds... though just for the fun of it, I will see about taking it to 4.6Ghz, I think that's a modest enough OC.
