What CPU for Vapochill (phase change cooling)?

OK so I have bought a modded Vapochill LS sometime ago and I want to use it to cool my main rig for a serious 24/7 overclock.
I was waiting for Haswell but now that it's out I am kinda disappointed on the temps I see. There seems to be the same problem with Ivy with the TIM not to mention the VRMs onboard dont help either.

Before Haswell was an option, I was told Ivy is not worth it for Phase Change, because its not that its a hot chip (something phase cooling can correct) but more so that there is no good contact of the cpu with the cooling system so no matter your cooling power the result is bad once you crank the Vcore. So Sandy was favourable to Ivy when phase cooling.
There seems to be now the same case with Haswell...
Well, is that true? Is it worthless to try Haswell on Phase?

If so, what do you suggest I should build? Shall I go with Sandy? I am kinda bummed if I have to go with 2010 tech and no pci-e 3.0...
Then, on AMD side the Piledriver is worthless, I will feel stupid if I get an FX8320 to 6ghz and have worse results than a Sandy on air at 4.8 for example...

Socket 2011, is it an option? The Hexacores might be too much for vapochill to handle (I was told it's good for up to 275-300W) and the 3820 is not unlocked :/ Should I wait for 4820k on Semptember? Another 3 months of wait and they might end up with bad TIM again and the wait would be for nothing...

I am so confused....kinda hope Haswell can work with Phase so I can stick with that, even if it will only do 5.3ghz...should be better than a Sandy 5.7 with the IPC improvements...

Phase cooling will let ivy & sb-e boot up at higher clocks than could be done with water cooling, but under load they all run hot enough to bring a single stage to it's knees. Sandy bridge & older cpus will still do very well on the single stage.
I haven't had a chance to play with haswell yet, although I'm guessing it will be similar to ivy. Validations & light loads should do great on the SS, but not sure what will happen under long heavy load

Blinky what do you plan on using this cpu for? You have listed quite different cpus in that some are less than half price of the others.

Also you do realise that not all chips are capable of going up to and over 5ghz, it will just be luck.

You would need to delid the cpu if your planning on going ivy or haswell.

I will mostly be doing this for the hobby, but I am not interested in something meaningless like max Posts or a quick PI death run...

Supposedly the goal is gaming, but to be honest I don't game that much anymore and even if I did we all know GPU is where the money should go.

So to give a more exact picture, I want a fast machine (even if I dont take full advantage of it) and I want the phase cooling to make some difference and not feel like I'd be better of with air.
I mean, in the past I've had twice 2600k and a 2500k and I had OCed them all to 4.7 GHz on air prime stable for 24/7.
Now to justify the phase cooling and the trouble it brings me (noise, insulation, maintenance) I would need to at least be able to have a 5.2GHz 24/7...
I am not interested if I can run PI at 5.7GHz with 1 core active or 3D at 5.5GHz with the machine 50% stable and barely able to pass the 3dmark test.

I just want to reach a nice speed (have a decent speed bump over air/water so I don't feel my cooling overkill goes wasted) and keep it that way for the next 2-3 years only changing GPUs possibly.

So it's not so much about performance needs, it's more about doing my hobby but stil without being totally pointless.
And what I mean about pointless? Well for instance what I said above, if I end up prime stable at 4.9ghz then it's pretty pointless to go into all the hassle/cost of phase to get 200mhz over air....
Another case of "pointless" would be if I used this cooling on an AMD 8350 and reached a high speed that would still result in lower performance than a 3 year old Sandy Bridge (possibly on air)...

I found this article, doesn't really address your questions re 24/7 on haswell phase. But looks fairly promising.

Hopefully this helps you out mate, its shame such a thread got next to no interest. Theres not enough extreme 24/7's around anymore!

Long live SS!
