Next up, a new case. It shouldn't be getting that hot. My 990x temps were in the low 80x max using the Phanteks.

Its Geil Ultra series - rated for 2133 Mhz 9-9-9-28.
The ram is allowing up to 186 Bclk at 1866 Mhz now, but the CPU wont get itself stable at 4.6 Ghz+, so its pointless going over 180 Bclk and 4.5 Ghz.
No, not happening. Temp differences wont be that great due to the case, I think you must have had a lower voltage chip or used better than stock thermal paste.

I suppose you can make some tea and fry some eggs on your heatsink while you're at it. 1.475v is a heck of a lot, no wonder you got 101C on the second core! I chickened out when mine started hitting 80C. 
What are you using this system for?

Put HT back on. No point moving from an i7 920 otherwise 
still not ideal
i wouldnt run above 1.4v tbh
my x5680 was the best clocking hex core 1366 cpu i had and that did 5ghz at 1.41v.
you need serious cooling for that and my load temps were hitting 80 which is the max i would consider for a 32nm hex.
a conservative 4.4 is the kind of thing you want to aim for using around 1.35v or less if you can.
unless you have a big waterloop then you can go a bit more mental

Why HT off? Surely the whole point of the 980 is for the extra cores and threads.
The HT doesnt do anything but increase temperatures. I'd rather achieve a higher clock speed with it off.
The extra cores are being used in several games I play, but the only thing I have that uses hyperthreading in Civ V, and even then it makes less difference than a higher clock speed.
My point with the new CPU was for the higher clock speed, and extra performance in a few games that can use all 6 cores.
At 1.38v and 4.55 Ghz without HT, the chip maxes out at 83 degrees after 15 minutes of Linx. I dont want it any hotter than that now.

Agreed - certainly would not run mine much above 1.35v if at all. A seriously expensive mistake could be the result. These cpu's are very good performers even at stock - which is what they were designed for.

Why not get it down to 4.4GHz and enable HT? The 100MHz will hardly make any difference and you get an extra 6 threads. After 4.5GHz, you need a big bump in voltage to achieve higher clocks. Below that, you can use lower volts. My chip did 4.5GHz fine at 1.35V but needed 1.4V+ to get near 4.6GHz.
