[OBR] Why is Ivy Bridge hot, power hungry and a bad clocker. - Page 19  

post #181 of 183
no the issues I am referring to is that the heat transfer currently used isn't targeted enough for a die so small. The die is extremely small, so small that current coolers cannot allow for the transfer of heat fast enough. Like under Ln2 there is a constant 20C minimum delta from idle to load, no matter how well you can cool it it never goes under 20C delta once you load it to a certain point like 50%, and reducing that isn't easy, imagine that.. Either way this isnt' so surprising to me, but we are also dealing with a new transistor, forget the uarch, the new transistor seems to be able to handle A LOT more voltage than Sandy. i was doing OCing and i set 5.5g and 1.75v so i can move up in windows, i had totally forgot to pull down temps, and I was running at 15C at that speed and temp and booted into windows on it, once i saw that on my DMM i was like holy ****, and then just poured ln2 and kept pouring until the CPu was at -185C which the lowest i could get the die temp(the cpu has no CB or CBB). i then proceeded to OC it and it max OC was not less than before.

These CPus can also easily take 2v under Ln2, however you don't really want to push too much volts or you will add more heat, the fact that these CPus can function under those high temps and high volts to me indicates that we are entering a real where the leakage is higher than it was before, thus for the same input power you have much more heat, thus meaning that at the same input power as sandy this CPu will run hotter, however the input power isn't that much of sandy, which is good.

Sigh. I was hoping to replace my rig but this seems.. Well no really a bad overclocker, the temperature is really deal-breaking.
