Ivy Bridge Temperatures – It’s Gettin’ Hot in Here

Interesting editorial by I.M.O.G. ... worth a read!

Why is Ivy Bridge so hot? Ask that question in any forum currently, and you are likely to receive one of two different popular (but not entirely correct) answers that everyone has been parroting:

  • "Power density is greater on Ivy Bridge than Sandy Bridge"
  • "Intel has problems with tri-gate/22nm"

The first answer is correct, but wrong at the same time – power density is greater, but it isn’t what is causing temperatures to be as much as 20 °C higher on Ivy Bridge compared to Sandy Bridge when overclocked. The second answer is jumping to conclusions without sufficient evidence. If you aren’t in the loop, there’s evidence of a considerable temperature difference nearly everywhere you look – we confirmed it by mirroring settings in our Ivy Bridge review, and we have read similar reports in solid testing at Anandtech as well as from other sites.

So why is Ivy Bridge hot?

Intel is using TIM paste between the Integrated Heat Spreader (IHS) and the CPU die on Ivy Bridge chips, instead of fluxless solder.

Hey man, im not trying to attack you

Just saying, the whole story is getting dragged out of proportion. Since that article at OC.com, everyone is talking about it, saying Intel is to blame, they did something wrong, etc. Now that finally people have started to do some testing, and report that the thermalpaste is not the problem, i think that closes this chapter. What bothered me about your previous post is that your still questening, while severel independant people have come to the same conclusion. If you really want to find out, do some testing your self. I think there have been lots of words, but very little facts from you and overclockers.com

"Intel" say it's the process/ die size

I have no world records, but I have some GOLD MEDALS.

Titan has nothing to offer that is worth the price.

It kinda makes sense the new tri-gate is giving some temperature issues.

Let's check the temperature issues in maybe 6 months when the process has matured a bit.

Intel has had this Ivy for more than 8months now. I think they'll spend a few more months on it but i think they're more inclined improving haswell[power wise]. haswell[mobile] is due 2013.

I couldn't agree more with it getting dragged out of proportion. A lot of people have taken what is in the story and ran with it, blamed Intel, or jumped to a lot of conclusions.

It does not irritate me that you put more faith in tests you have seen than how much faith I place in the tests I have seen. I think everyone has a right to make up their own minds. My mind just isn't made up yet. It looks like there could be some flaws in the few user tests I've seen. I probably need to look around more.

I don't intend to do any testing myself with delidding however, I'm just going to pour some LN2 on one of these buggers and freeze the crap out of it. That is more my thing. I've actually been traveling since I published the story, though I did buy a 3770K on the way home yesterday.

@Hondacity: I didn't take anything from the inquirer or XS for this article. I confirmed the W/mK from rge's comments on OC forums and research. I don't know if the inquirer wrote anything about this even?

Ya, cool to see more tests being done. Hokie posted that over in our Overclockers discussion thread, after seeing it referenced on VR-Zone. The site that did the testing actually replaced the thermal paste and still used the heatspreader (sticking it back on with 2 sided sticky tape), and seem to have gotten good results - a lot cooler when overclocked using different paste under the IHS.

Their results show more improvement than I would expect from just replacing the paste.
