Might need to upgrade your cooler if the heat issue from early testers prove correct
 
The IB TDP went up from 77W to 95W, and the TJ Max is 105C*; in comparison the SB i7-2600K is the same 95W TDP with 98C TJ Max and SB-E is 130W TDP with 91C TJ Max.

I still don't like the idea of a 4.7GHz~4.8GHz running 97C~98C which is only offers a 7C~8C margin best case from CPU throttling or drop-out. By comparison a SB @ 4.8GHz is 68C or 30C margin, and SB-E @ 4.8GHz is 72C or 19C margin.

*based upon what I've seen so far.

I sort of get it.. basically, for practical purposes, I want to stop at a safe temperature. I'm assuming IB has a higher threshold for CPU temperature (maximum it can take) than SB, but let's say they're the same. I want to stop at 70% of unsafe temperatures... which will get to a higher clock... IB or SB?

Lemme try rephrasing. I want to stop at 70% of maximum CPU temperatures (when it becomes unstable). Which will go higher... IB or SB?

It's very possible that the BIOS vendors don't have a perfect understanding of how IB behaves with different voltages which causes the mobo to run it with a higher vcore than it needs. Let's wait for release and see what happens with the following BIOS updates.

Good point :)

Are any of you planning on getting IB right when it comes out? Wait... dumb question. I don't think anyone's going to go from SB to IB, but new builders will have IB. Is it strange that I'm already excited for Haswell?
 

The i7-3770K has a TJ Max is 105C*, so 105C*0.70 = ~74C so best guess low 4.XGHz (~4.2GHz).

From what I've been seeing I have to wonder if the Ivy Bridge is really going to be as good as people are making it out to be. It seems there is little performance increase with greater heat. Sounds alot like Bulldozer.

Bulldozer was performance loss with more heat ;)

No but there was stuff floating around on the internet before Bulldozer was released saying that it runs hotter, and slower then previous AMD and Intel CPU's and that ended up being 100% true. Either way I don't care because I'm not switiching to Ivy Bridges I'm waiting for Haswell. By then if there are any problems Intel should have the problem fixed.

I wouldn't be surprised if there isn't a big performance gain either, but I would be surprised if it does run hotter than SB (not at launch but after the platform matures). Like I said in my earlier post, I'll bet some of those early reviewer BIOS revisions overvolt the CPU to ensure it stays stable (especially with turbo boost). We even see that on mature platforms.
 
For those that have a SB now, IMO you'd be nuts to toss (sell) your CPU. I remember all of those folks saying "...as soon as the IB comes out I'm gett'n one and selling my SB..." to those folks, don't. If you're wanting to toss cash then I can see benefits to the Z77 with the improved Virtu or simply add another GPU or be happy.

By the platform maturing, do you mean hardware or like... drivers? Meaning, if I buy an IB chip when it comes out, and they make it better later on, (platform "matures") will I be able to reap the benefits of the changes they make? Via software? Or will it end up being a different chip, and I'll be stuck with the hot first edition?
