Intel's Ivy Bridge Hotter Than Sandy Bridge When Overclocked

[blazorthon]

[citation][nom]josejones[/nom]There sure seem to be a lot of heat problems with several Ivy Bridge CPU's not just the i7 3770ki5-3550 Ivy Bridge review: i5-3570K Ivy Bridge review: http://www.newegg.com/Product/Prod [...] 1nhsu8zv95Is Intel going to fix the heat issue or not?[/citation]

The problem is not i7-3770K specific, as you said. It's with all Ivy Bridge CPUs. At stock clocks, the heat problem is null, but when overclocked, they heat up more than Sandy does despite the lower power usage. The greatest culprit of this seems to be the paste used in place if solder between the CPU die and the IHS, although the die shrink may have played a part if it increased heat density to a point greater than even the solder could handle as well as the previous generations of CPUs (after much thought and discussion with the other members of this forum, I'm convinced that the paste is the greatest problem).

Intel might fix the issue. It seems that it would be an easy fix to at least remedy the situation by returning to solder, but Intel probably won't do that until Haswell, if ever. They seem intent on reducing the overclocking potential of their CPUs in a way that doesn't hurt power efficiency or stock performance.

Well Blazorthon seems to be right in that that this is not a problem to Intell. Ivy works like a dream at stock settings, so no worry. But I can see special OC versions at huge price in future 🙂
Well, maybe not, but if there is no need they will stick to low production expensies as long as they can. And at this moment they can do it.

I think that Intel would have been better off doing the paste for the non-K edition CPUs and leaving the Ks with the solder. That way, the CPUs that can really benefit from the better heat conductivity would and the CPUs that don't benefit from it are cheaper. Well, it would have been better for us.

Yes it would have been... *sigh* But this does definitely leaves room for stepping upgrades or really good for Haswell, If they for some reason have to try harder...

i personally think intel had some extra thermal paste and decided to slap it onto the chips instead of soldering it like before.

One of those quotes from newegg was mine. The problem was the stock cooler. I got a CM 212 evo and temps are fine at 4.2Ghz. Never goes above 60C now max abuse on all 4 cores. I could really care less if the CPU at max load is 60c rather than 40c. I never planned to OC more than this and I wouldn't a SB either for my uses. For extreme OC SB was probably better but this performance IMHO is more than acceptable.

I still give intel -1egg for supplying such a crappy cooler on a top shelf chip. The cooler that came with my old pentium D was 2X as large and copper core etc.

so what i have to do when i overclock my ivy processor? just adding few more fans/coolers on the case would be enough or i have to do something more?

You don't have to do anything more. Adding case fans would probably not help anymore than it would with Sandy, if even that much, simply because this isn't a problem of excess heat, it's a problem of getting the heat from the CPU die to the CPU's IHS. You just need to make sure that you don't push your CPU too far if you go with Ivy Bridge. It's not like it can't have similar performance to Sandy anyway, just at a lower frequency.

There is an article in Muropaketti (Finnish hardware site) where they did replase the Intel heat "insulator" with more proper stuff:
http://muropaketti.com/artikkelit/prosessorit/ivy-bridgen-lammonlevittajan-irrottaminen-ja-vakiotahnan-vaihto,3

They did find out that with Intell stock cooler the CPU with OCZ:n Freeze thermal paste runs 12-14 Celsius less than normal Ivy-Bidge.
Overwolted Ivy with the OCZ:n Freeze was 9-13 C cooler than original.
Overwolted Ivy with Nochtua NH14 cooler runs with OCZ:n Freeze stuff 13-19 C less than original with the same cooler...
- (Intell stock thermal paste 95 Celcius, OCZ Freeze 80 Celcius with the worst core)

So Intel really did make an interesting choice when they made the Ivy. Who would be surprised if Ivy-bridge E would come with proper thermal paste solution just to justify the price difference?

The diffence with highest clock achieved was not so impressive, but the redused heat was big improvement!

The problem is that the changing of thermal paste is not so easy to do without damaging the CPU. So don't try it unless you really know what you are doing!
