Anyone complaining about heat obviously hasn;t been around long enough to remember the old Athlons: http://www.phys.ncku.edu.tw/~htsu/humor/fry_egg.html

Wonderful! I'd forgotten that one. Yet is was the Prescott that really pushed out the heat - another case of a brilliant over-clocking chip, Northwood, that was die shrunk to come up with Prescott; and all the heat that came with it.
My guess is that Haswell will run fairly cool,

OK, here's the really important question for those who now have and Ivy bridge -
"Is it what you were hoping or would you have been happier with a Sandy bridge that runs much cooler."
"Is it what you were hoping or would you have been happier with a Sandy bridge that runs much cooler."
Given they are the same price, I am glad I got a 3570k and not a 2500k.

Well, I just ordered my Ivy so i hope I am happy too! getting the H80 cooler as the size of coolers needed just won't fit my case - a coolermaster storm.
I hope all of you waiting for Haswell are more prepared for potentially more IGPU improvements and small CPU IPC increases, i'm not saying it will be like that, but lets not think it'l be a 5.5ghz beast or anything before we see early signs of that first at least

I know you meant it offhandedly but is seems others really perpetuate that thought more seriously. 22nm is ready, it delivers silicon which is more than viable it is just not as polished as the mature 32nm.
I hope your right but it`s looking more and more like heat is becoming a big problem.
You could say the same about Bloomfield. My near 4 year old i7-920 is still an excellent CPU, not seeing any real need to upgrade it.
But if you only intend to play games then running IBT was always just more of a "situation i'll probably never encounter but it's good to know" kind of benchmark, while I agree that it doesnt exactly sound encouraging that the chip cant run IBT without getting incredibly hot, I dont think that really means it's unstable or anything hinting at that, it's just a hot chip no matter what way you look at it, it just depends on what overclock you're aiming for as 4.5/4.6ghz still sounds relatively easy to achieve

Yep I get that around 4.4Ghz, 1.175v
Looking at some others say they needed 1.3v for 4.5Ghz, seems like I got a good chip!
Just checking i follow the reasoning:
ibt runs the chip hotter than prime. Instead of lowering the overclock to deal with the inadequate cooling, the plan is not to run ibt?
That's a pretty lax definition of stable
Yes normally i would agree.
However i have had to rethink this with IB.
The chips have a problem dissipating the heat generated, a design flaw i suppose.
I had read the reports about the high temps but it was still a shock to experience it first hand for myself.
It was a < insert three letter anocronym> moment, the catalyst for my initial post.
Reducing the clock speed and vcore brought the temps down from the throttling zone but it was clear that the chip would not be suitable for sustained high loads.
Whilst gaming and encoding using handbrake the temps were OK, a tad higher then SB but no where near the danger levels observed with AVX prime or IBT.
I use AVX enabled clients using the P95 math libaries 24/7 on my PC's and from my initial testing quickly realised that it wouldn't last long doing that.
At least not at the target clocks i had in mind.
Still only a minority run there CPU's flat out with highly optimised sofware 24/7
so it shouldn't be an issue for most.
Where it may be an issue is when proving stability.
How risky is allowing the IB CPU to run at the elevated temps generated using IBT. ?
They may prove to be hardy, but a warning is in order i feel.
