Ivy Bridge Temperatures Could Be Linked To TIM Inside Integrated Heatspreader: Report

It makes a vast difference according to the Japanese test.

Just to be clear, they DID NOT MOUNT THE HS DIRECTLY.

They just replaced the Intel gunk and remounted the IHS ...

So they did. Reading the article does'nt make it clear what procedure they used but if you click on the link at the bottom of the article it has pictures of how they did it. Still, it would be nice to know how much difference removing the IHS altogether would make.

If you use Google Translate on the original article, it's quite easy to understand. The Japanese ---> English auto-translation has come a long way in recent years :)

I think results will likely vary hugely with the latter, due to the difficulty of the method and the fact that almost all coolers / heatsinks are not designed to work without an IHS, these days.

The Japanese publication has a good reputation and has been very reliable in the past, from what I can gather. If a couple more people can confirm that replacing the crappy Intel TIM yields a major improvement (and I'm sure it will), the bad publicity might force Intel to actually do something.
 
You would certainly hope that to be the case especially as the K series are aimed at enthusiast's. I suspect that all they would do though is to launch a new stepping with different TIM and that current owners would have to put up with what they have already.

That's one of the reason's I chose to go with a 2500K, if they do release a new stepping that solves the heat issue's I think I stand a better chance of selling my 2500K rather than a hot IB

I think Sandys are only worthwhile for people wanting very high clocks (4.8 +) otherwise you may as well go Ivy

I'm running my Ivy now - 4.3 @ 1.13V - and it doesn't get hot at all anymore :)

But my point was if there comes a time intel decide they are going to fix this, what is going to happen to all the people that have a hot running ivy when they want to sell?

No one will buy them when and if there is a cooler running one or they could get a SB with no issues cheap second hand.

If you intend to run this CPU for a long time, rather than sell and upgrade swiftly, I don't think these temperatures or the extremely poor TIM used on the heatsink bode well for longevity or reliability at all.

Electrical components, particularly silicon-based circuits, degrade exponentially, the higher the temperature they run at the longer they do it for. Also, those cheap TIMs degrade into clag / crumble swiftly, compared with better ones.

It's clearly that super-cheap plasticine-like TIM. I seem to remember that a test of various TIMs a while ago put it at a similar level of effectiveness as a slice of that revolting, yellow processed cheese at stock-clocks .... no wonder people are seeing 10-25C improvements after replacing it.

This, ladies and gentlemen, is why monopolies are bad and we need Piledriver to be a success ... or there'll just be more of these shenanigans from Intel.

I think people are being to hard on Intel. After all Intel have been on a roll since 2006 release one market leader after the next so I think we should begrudge this minor oversight.

Minor oversight?

This was not a decision made by engineers. It was made by people who wanted to make 50cents more per CPU, at the expense of a massive degradation in thermal performance. It would have been explained to them exactly how bad it would be and why it would be so bad by the engineers.

They didn't have to use solder. As these tests show, they could have just used a TIM of decent repute.

Did it not cross intels suits that the tim would degrade over time. Oh wait....the next socket/cpu will be out by that time.Tick....Tock new SOC(ket)

Like I said ... it would have been explained to them in excruciating detail by the engineers ... and they would have had a range of choices of TIM. Looks like they went for the very cheapest possible ...
 
think you could just run without the cover on it using a H80? :P *brain cogs turning*

maybe a stupid questioni but are you limited to a type of TIM for this? i.e. would it be possible to use artic silver or IC diamond on the exposed core between that and the IHS.

or even using it without the IHS and have it contacting directly to the H80(or any other cooler for that matter)... but im not too sure if there would be other mounting issues as the cpu is held in place by the socket clamping onto the IHS.

what you all think? i'm so tempted to buy two and try this on one of them xP if you can get about 10oC cooler then it's worth it IMO
 
Just curious, does the processor ever actually enter this 100% load that prime95 put's it under? oc'd 4gig max temps are 69 73 70 69 after half hour.. so won't be too greedy but just curious about the 100% load question

I can play BF3 for a couple of hours with two 5850's also dumping heat in the case and my cpu temperature is almost 20 degrees less than under prime.

That's actually not a bad way to test for stability for everyday use, let's face it, prime and IBT are really to find if it's stable, why not just use BF3, as you probably know, BF3 will crash an unstable overclock just as good as prime will or IBT, plus it will give a more realistic real world temps to go by.
 
My sarcasm detector is tingling?

The guy asked whether you'd usually see the 100% load that prime exhibits. My personal pc at most plays battlefield 3 or similar. I simply gave him a temperature comparison playing a game that is by all means a defacto benchmark used for both gpu and cpu related reviews.

Stop being such a bell. You obviously are the fountain of knowledge mate so you crack on and all that ;)
