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

[Kallenator]

Is there anyway to replace the TIM and reglue the IHS back on and not loose warranty?

I think it is somewhat possible, however it strongly depends on what kind of routines Intel have for checking CPU's that they get back...
That being said, a perfect IHS refit would be hard to spot, and I would not feel guilty about returning a CPU with a refitted IHS if I was 110% sure that it didn't kill it.

Only if the person at Intel has NO idea what they're looking at.

Yeah right. I doubt it is a very senior position. Get glue that matches in color, but it on square or aligned how Intel did and I doubt anyone would notice.

It's nothing to to with the TIM. Well, maybe a few C at best. Sadly, the increased heatload is due to the higher density of 22nm architecture and nothing more. Think of it this way: more performance than IB but waaaay more transistors (IB has 1.4 billion vs 995 million in SB) so ~40% increase is A LOT of heat. The result? Even though it's a smaller process there is much more heat. To think that TIM could the single factor for such a huge change is a little foolish IMHO.

Did you even bother to read this thread? People performed tests and in overclocked+overvolted conditions, there can be over 20C difference just due to TIM.

I did read the thread, and I don't agree with the blanket statement that 20C is a typical difference, but it's ok to disagree. IMHO the higher transistor count (even though they're trigate) is the basis for the much higher temperatures.

Edit: I get the lapping, removing IHS, using better tim's all account to lower temperatures. That is fine. I think though that the increase is more to do with density and less to do with TIM (that's all).

I didn't say that it is always 20C, I said that "it can be" over 20C.

I do agree that a higher heat density is responsible for higher temps, but it has been proven that replacing the TIM under the IHS can improve temps. And in some cases the difference can be very substantial.
