So I was wondering, I know one of the long list of reasons why Ivy Bridge CPUs where so much hotter than Sany Bridge based chips was down to the slightly concave IHS compared to the near perfect design on SB, combined with the 3D tri gate transistors and poor quality TIM over fluxless solder it added up to a significant difference
Anyway What I was wondering was if you where to delid a 3570K and replace the TIM with Coolabratory Liquid Ultra and you managed to delid a 2500K without destroying the IHS would it be possible to transplant this onto the newer chip and if so would it improve temps?
Again just a random thought I had it be far to expensive to consider unless you managed to get a damaged 2500K for cheap
I don't see the point in overclocking these chips mildly for a minor difference with consumer cooling. Either you go extreme or you don't OC at all, intel OCing is dead since 2009 (well not really, sandybridge was the last good overclocker, though i3s and pentiums and celerons were left behind).
If you just delid an Ivy Bride CPU and replace the TIM with high quality thermal compound, you fix the Ivy bridge heating issues. No need to transplant the heat spreader, or anything drastic like that. Also, from what I understand, this issue is specific to "k" series CPU's, or at least desktop CPU's. Admittedly, I haven't been digging too deep into this issue because I have a 2500k :P
Using a box knife (we do not recommend doing this at home), the author of the linked story pried the heat spreader away from the chip and was able to replace the cheap paste Intel used, trying out both OCZ Freeze Extreme and Coollaboratory Liquid Pro thermal pastes. The OCZ offering allowed for 1.55 V at 4.9 GHz, while the Coollaboratory material ramped up to 5.0 GHz, operating stably. This was accomplished even with air cooling, although the author did not use a stock heat sink, opting for a Thermalright Silver Arrow SB-E instead (Ed.: this information was pulled from the original Impress PC Watch site with Google's rather shaky translation of Japanese). If there is a smoking gun in this equation, we think this is it, especially considering that the researchers at Impress PC Watch managed 20% more efficient cooling
If you decide to de-lid your CPU, I strongly recommend using the vice method rather than trying to remove it with a razor or box knife. If you use a blade, you run the risk of scratching the die.
If you de-lid be extremely careful. I wouldn't use a box knife as you'll need to do some prying with one of those to get under the heatspreader. Use a blade from a safety razor (also called double edge or DE) They are a lot thinner, flexible and mad sharp. This way you don't have to pry and potentially damage your PCB. Just tape one side of the blade up, be VERY patient and you should be good. You can damage the actual chip itself if you suddenly break through the glue too fast so just watch out for that.
