Hmm. This could explain some things. What if some of the review chips have TIM, and some are soldered? What if Eggy's chip wasn't a dud, and it just had the TIM like the engineering samples (the chip overclockers.net reviewed was an engineering sample). Hmmmm...... There have been alot of inconsistencies in the data I've been seeing, perhaps this is why?

the only reason my temps are so relatively low, is because the voltages are low aswell. if i try to go for 5-5.2 ghz@1.35-1.4V i see the same 99C peaks other reviewers do at that voltage. sounds like silicon lottery to me

IIRC overclockers.com reviewed the 3770K, punceh has the 3570K, the Hyper Threading on the 3770K will add a lot of heat, also they fail to say what voltage the 4.5Ghz was achieved with. It's not the frequency that generates most of the heat, it's the voltage. If punceh has a good chip and is able to run 4.5Ghz with 1.18v then ofc his chip will run colder then Overclockers.com's chip if theirs required 1.25v.

I have posted this many times, all the chips i tested (2x 3770K and 1x 3570K) was RETAIL chips, they are not ES or anything like that.

I think we're pretty safe to say that the die shrink and the epic fail of using paste instead of older is causing the heat. I actually think that is good news, this means that hopefully Intel will see in the sales numbers and the reviews and so on that they made a epic fail and fix this on the Ivy-E chips before it's launched. If the temps was due to something very different it may not have been as simple to fix and we could see the same problems with Ivy-E.

hello everybody smile.gif

Sandy Bridge 2500K Vs Sandy Bridge-E 3930K Vs Ivy Bridge 3570K
at Stock Vs 4GHz Vs 4.5GHz in a lot of benchmarks smile.gif

After Page 7 there are many many charts:

Anybody trying to use a water block (imho an air heatsink might break it because of the weight) directly to the CPU without the IHS? It'd be awesome to know the temps tongue.gif

some finnish guy apperently did here
though as was later explained in that thread, the water block he used uses a fixed amount of pressure on the ihs, with the removal of the ihs there is less pressure on the die, thus making the contact fairly weak.
i dont know how it would react with a (water)cooler that can properly apply pressure regardless of ihs height or not.

Yup, I though that too. The block is only going to make contact with the metalic (die) part but using thermal pads with the same height around might provide decent pressure.
Something like this:

Btw, I'm pretty sure that at least changing the amount and quality of TIM would improve 5-8ºC

well using those pads would be probably a bad idea because they probably wont get perfect contact a IHS+tim/cooler+tim would get, then they need to have more thermal conductivity than the tim(i dunno what those pads have). best is just a cooler that has enough pressure on the die. switching the tim will probably give an improvement, but when you have the ihs off anyway i guess its better to just put the cooler on directly(even if it doesnt have perfect contact with the die).
either way, removing the ihs isnt something most people will be up to i guess tongue.gif i might do it at some point if it shows better results(when i get my water loop soon(tm).

Shame... I was kinda trying to be optimistic, as I am/was hoping to get a 3570K to replace my aging core 2 duo. If it really is a lottery on performance, I'm not sure I want to anymore. I'll have to wait till more people get their hands on the chips.

Are all the ivy chips paste TIM, or just the cheaper ones?
