It's the issue of delidding that causes ivy to run hot. Delid ivy and it'll run very cool. I mean with just an nh-d14 i'm able to push over 1.5v for small fft. That's something you dont see, on sandy you'd need custom water for that.
Well, 22nm means there is also a lower surface area to dissipate the heat. This appears to be why you can cool a GTX 480 pretty well on an Antec 620, despite its massive power consumption.
Also, there are plenty of people running 1.496V on air coolers in the Sandy stable club. they have to run a blend test in that club, but it tends to get as hot as small FFTs in some parts of that test. One guy had a hottest core of 80 degrees on a Silver arrow and 1.496V.

Also sandy ran alot cooler then ivy
Ivy actually runs cooler than Sandy, it's just that the heat can be dissipated better on Sandy, so if you have unlimited heat dissipation (like a custom loop with a 480 rad or something), sandy will probably be better, but if you can only run an air cooler or a CLC, then delidded Ivy may perform better.
If you don't have the nerve/cash to delid, Sandy will definitely perform a lot better.
