Sorry for the delay, it took me a few days to dig out the assigned password to be able to post again.
It appears that the 60-62c temps reported by the motherboard in the bios are somewhat off. Don't get me wrong, sometimes AMD Overdrive shows TMPIN1 as 0, TMPIN2/3 as 248c, and TMPIN4 is always 249.6c, which I'm pretty sure is inaccurate as well.
But when AMD Overdrive is working properly, it reports 31-32c for each core, TMPIN1 @ 51c, TMPIN2 @ 53c, TMPIN3 @ 39c, and as always, TMPIN4 shows 249.6c.
With the stock cooler I would get much the same or slightly higher temps, but the fan could be heard even when some distance from the machine. So I bought a Hyper 212 plus, and am now getting the temps shown above, and can barely hear the system even when sitting right next to it.
Thanks for all the help!
