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

[Ollie1132]

I think usually around the same with high end air/all in one water cooling. Although 4.6GHz isn't a poor overclock by any means I just would have liked to see a little more improvement between CPU generations than what is essentially just a little power saving from improved efficiency and IPC.

True. This is more of a step forward for mobile processors than desktop.

looks like the same low quality gunk they use on the xbox 360 lol

Edit: I think I'll take one for the team!

Jokester : He never lost his hardcore Get the razors out!

I suspect that my only option would be to replace the TIM and put the cap back on, and I'm dubious that it'd really do much.

Something that could be done I guess is sanding down the edges of the cap so that it makes better contact with the core?

Hmm its been a while since Ivys went on market and still no proper IHS free tests hmmmm.

I'll give it a go this weekend, just trying to find a cooler that will cope with the IHS not being there. My Noctua won't work, my EK Supreme looks like it might just get away with it, but failing that I've got a Koolance 370 that looks like it'll have no problem at all.

Jokester - Can't you just apply some decent compound to the top of the core and refit the heatspreader as a gap taker?

I all ways believe random guys on the internet
Loaf of bread not kneaded as I have one of my own, thanks though.

So you ran IBT, did you do it at maximum stress for 10-20 runs? would be interested to see that and of course the temps that go with it.

I've just run it but the gigaflops seem low? What should they be?

I also ran linx at 4.7 and got max of 76 degrees and its toasty hot here today.

Here's a crude paint diagram to illustrate a slightly different explanation of the point that I don't think I got across above.

The black area (including the blue highlights) is the heatspreader/cap/IHS. The grey is the paste, and the red is the core.

I wonder if the paste is not just filling in the holes between the IHS and the core, but that it's filling in a gap between them and they're not flush.

That's all that I can think of to explain temps difference that large... as if someone has inexpertly applied TIM as you might do with adhesive when tiling a bathroom wall.

That's why I'm wondering if there would be a benefit in sanding off the areas I highlighted in blue, once the IHS was removed so that the CPU would be flush with the IHS, meaning that the TIM was only filling in the microscopic holes and valleys, rather than being a distinct layer.

Just a theory.

Start removing the lids and replacing the TIM Ivybridge owners!

Yes, in a different thread I think

My 2500k at 4.6 get about 63 gigaflops I think on a standard run, I think it goes up slightly at a higher stress level

 

[-Mike-]

Ahh thats fine then Shall go run again

 

[mr griffin]

looking forward to ur results Jokester - well done that man

 

[-Mike-]

If his results are very good I think we need a

"*** the official I sliced my cpu die off thread ***

I bet plenty will have a go depending on his results

 

[hyperst]

What I don't get about all these high temps is how the GPU's have also shrunk this time round but are not suffering high temps, in fact it's quite the opposite

I think what everyone wants to see is a replication of the Japanese test.

I.E. removing the IHS, cleaning the Intel TIM gunk off, applying a good quality TIM, replacing the IHS, then running as normal.

Of course, it's your chip and you can do what you want ... but I'd have thought this is the best thing to do, and considerably less risky than mounting directly - which as you correctly point out will be difficult to get good contact / adequate pressure anyway.

 

[Jokester]

Replacing the TIM won't much difference.

 

[pmc25]

Replacing the TIM won't much difference.

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 ...

 

[Krono5]

You should probably test both to be sure. Replace the tim and test with the IHS on first, then with no IHS. Thanks for doing this btw, it'll be nice to finally have a good source of info.
