Consuming slightly less power but significantly reducing die size means greater power/heat density.
Also, it was inevitable that moving to a smaller node would make the leakage curve less favorable. Moving to tri-gate transistors likely did reduce leakage, just not as much as people were hoping for.

It is Intel's new 22 nanometer technology with Tri-gate transistors that has brought these limitations. The transistorsare extremely tightly packed and the die size is so small compared to earlier processors, that the heat cannot be removed fast enough with air and water cooling. Rumors has it Intel is not entirely on the mark with the new 22 nanometer technology and a box shot of a Core i7-3770k shows a higher TDP than earlier expected.
I said nearly the exact same things two days ago, and half the people on OCN think I'm crazy because I can do basic arithmetic.

Cost is the main point behind a die shrink.
And power consumption was reduced slightly. They could probably have gotten away with saying 77w TDP, but the increased total thermal resistance from the greater relative reduction of the die size probably means that coolers designed to only move 77w of heat can't keep the temperature delta between ambient air and on-die temps acceptable, even if that's all the heat that is produced.

The real problem is that people have stupid expectations based around abject ignorance of very fundamental principles. Neither Ivy, nor BD should have come as much of a surprise.

Water won't help, that much.
What people refuse to understand is that these chips are not hotter because they are producing more heat
They run hotter because higher thermal density increases the thermal resistance of the system, which makes it harder to remove heat from the die. If the chip is only producing 100-150w of heat while OCed, the difference between an air cooler that can move 250-300w of heat vs a custom loop that can move ~700w of heat still isn't going to be that big.

Would totally defeat the purpose of the die shrink.

You can probably do 4.5GHz on the stock cooler.

There is a reason NVIDIA dropped the IHS in their current generation of chips.

No they haven't. People just have no sense of history and anything that happened more than 10 minutes ago doesn't factor in to their reasoning.
Ivy Bridge is Intel's tick
. It's a die shrink and minor refinement. Not a brand new architecture. Guess what? The last tick that happened two years ago went pretty much exactly the same way.
The is the same deal as Bloomfield vs. Gulftown. Gulftown, even the quads, do not overclock much better, or run much cooler than Bloomfield, and no one pitched a fit over them.

Intel chips do not handle heat better.
You only think this because you don't realize that reported temperatures on each platform are not reporting the same thing.

Ivy doesn't seem to OC worse in general, than Sandy.
I have both a 2600k and a 2700k, and neither of them will do past 4.7GHz on air. 5GHz is pretty rare for a 24/7 stable, air-cooled OC, on Sandy.
Most Ivy results so far are showing 4.7-4.8GHz. Which is quite comparable to what Sandy is typically capable of.
