Just got home and did the following:
Undid my settings and set just the following:
Turbo =off
CPU ration = 20
Bckl 160
dram freq = DDR3-1600
CPU volt = 1.225
PLL = 1.8
qpi=1.225
Dram bus voltage = 1.6
Everything else was auto
Idles were 34-35
Prime95, all 8 threads running large FFT's temps were 64 62 64 62.
Can anyone tell me what's different? My ambient temp is down 3-4 degrees F, that shouldn't equate to 10 degrees lower load temps, though, should it?
Would setting the CPU ratio to AUTO lower ambients a couple degrees more or is that more of a power saving thing?
I'm really trying to undestand more and more of this

Edit: Update
I tried the same settings with a BCLK of 170 and by the time i returned to the room 15 minutes later, it rebooted itself. Could've take 30 seconds, could've take 14.5 minutes - I don't know.
So I upped teh vcore and qpi voltage to 1.25
Completed 15 minutes of prime with temps going 70-71, 68, 68, 68.
Ambient temp in front of machine is 77.1F.
Do you think the machine was upping voltage on it's own to create the higher temps from saturday/sunday?
2nd question, with OCZ gold DDR3-1600 RAM, do I need to throttle it back a bit? It's list at a freq of 850 in CPUZ. I thought i read somewhere 1600 should be 800.
