My new Ryzen 7 2700 running under a 140w load (small fft @4 GHz) runs at like 70c. sooo... the I5 got a lot lower temps after the lap. Lapping is not that hard.

The flatness to avoid cracking is simple in that any thermal shrinkage or expansion is also more uniform. This thermal expansion and shrinking produces stress in the material. While in a liquid state this is not so much an issue other than potential low level pressurization, but as a solid having different section properties (i.e. thickness) the thermal stress in the thicker sections will increase the stress upon the thinner sections causing cracks within the thinner sections or somewhere in the interface between the two. This same thing happens in concrete a lot and has to be accounted for in design.

One thing I realized on my 7900X is that the hottest cores were the first, last, and middle 2 (4 out of 10). They were consistent, with different cooling solutions, water blocks, thermal paste, and even with the stock IHS vs copper IHS. Now, I don't know if those are "accurate" representations of the physical layout, but it almost seems to me that, if consistent, they could be "center cores", or at least cores in more "dense areas". I mean, this is all speculation, as I've tried getting core layout info from Intel and it doesn't seem to be publicly available. Just food for thought… :)

You kind of answered my question from the last video of why the surfaces aren't polished here to create traction to thermal paste. Still curious though if maybe a direct copper to copper contact wouldn't be better. With a perfect polished surface you wouldn't need an interface material. There is a company that makes a laser dial indicator as an add-on for their laser calibration system. It could be used to make sure there are no variations or any concave or convex surfaces. Obviously not practical for the home overclocker but for a person that is going all out I think it would be the thing to do. With an instrument like that you could even test for variations coming from contraction under the nitrogen. Due to differences in thickness of the contact materials, the rim thickness of the spreader/block vs the center thickness could cause the metal to shrink under nitrogen temps creating a gap.

I am wondering, why LN cooling teams use all this sponge, tape and so on to cover entire motherboard (to prevent condensation) - instead of using just a closed case filled with a completely dry gas, like pure nitrogen? No humidity, no condensation. You can make such tank with acrylic sheets or smth like this. It even does not have to be pressure tight, just rubber around all cables, rubber seal around the LN pot to fit it in the top cover. You get rid of humid air, you do not risk condensation on spots of the MB that you missed. You can even provide some kind of a loop of cool nitrogen gas, to provide additional cooling to VRMs and RAM. Is there some kind of a trick that would make it fail?
@Rippthrough5 жыл бұрын
Lapping isn't the be and end all for mating the surfaces - just because they're flat doesn't mean they're parallel, etc. If you want much better contact for LN2 then instead of grinding them both on stones you should be mounting the cooler and CPU, bluing them and then scraping the two surfaces into each other. That will take actual physical contact up from single figure digits into the low teens.

Perhaps you guys could explore the idea of using the CPU's heat spreader as the base of the LN2 pot - ie you just have a tube attached to the top of it, removing the thermal paste and the need for lapping. The low temperatures wouild make materials used for seals a bit brittle, but I think it could be done with precision machining of the heat spreader and pot walls, perhaps on a lathe for example.

I'm always confused/puzzled by lapping. Given the whole purpose of the liquid-metal/thermal paste is to fill the gaps between the cooler and the IHS and because its a liquid it that fills any gaps caused by 2 uneven surfaces, it already makes the two contact each-other better. The only thing I can see lapping doing is making the distance from the silicone to the radiator a few nm shorter.

Steve, you should contact Intel and show them the results here. My 7980xe had a 37c core delta before I delidded it. Now it's 10c and I think that's still too high. I suspect a manufacturing defect on that chip is the cause of the problem. Possibly a bad seating of the IHS before it was soldered, which might be explained by what resembled a slanted surface in addition to your non-flat surface when you were lapping the CPU.

Since you have the 7980xe de-lidded I'd be interested in more testing with the heat spreader. Not only lapping but testing the inside for consistent thickness. I'd also be interested in seeing if different thicknesses would affect the performance and if different profiles would have any impact. For example, feathering the heat spreader thickness towards the edge both thinner and thicker. Also, once lapped and of uniform thickness, gradually remove a layer of a fixed percentage of the starting thickness. So, if the lapped and even heat spreader is 2mm then remove 5% or 0.1mm. Though typing that out it seems like it would require multiple heat spreaders and a ton of work.

Lapping confuses me because when I put my air-cooler, the screws usually go down until they lock. Meaning they have run out of thread before they are stopped by the IHS.

How do you think the IHS gets a curve to it? Certainly they are milled flat initially on both the underside and top-side. I would bet that the interface is not an issue as much as the underside of the IHS being curved to match the top, warped during nickel plating or uneven deposition of material I would guess. It may be possible to lap both the underside of the IHS and the die itself to reduce core-core deltas. Lastly I am surprised that kingpin does not have a jig to hold the IHS to lap perfectly flat rather lapping it by hand on his machine.

My water cooler couldn't even keep it cool at the 4.3ghz overclock I was running I would hit 90 really fast, as soon as I hit the benchmark on cenibench or aida 64 it would start hitting throttle limits pretty much instantly. I then decided what I should do. LAP. I lapped my CPU and my cooler master masterliquid lite 120. Lol (mouthfull) any who.... I can ran same overclocks and now I was sitting in the 60s so I overclocked it to 4.5 and increased the voltages and now I'm hitting 80s after about 15 minutes and it flat lines and doesn't move. I'm sure if I had that unrealistic test running with my GPU on stress it would hit around 90 but that's unrealistic stuff. I'm glad I lapped my CPU and water block. I watched jayztwocents about his cpu hitting 90 instantly and check to see if my cpu spun on the table like a top and it did. Then did all my lapping and was happy I did. And don't say it was un even mounting pressure because I tried different thermal pastes and tried mounting the block in different positions never changed my temp.

So it's nothing to do with copper being a far better conductor than the metal layer above it? And actually is the perfect flat a better conductor? Surely having a highly regular finely pitted surface would increase the surface area possibly using a nano material, and could allow a higher contact between that and the cooler increasing the cooling efficiency?

Interest registered. I would also be curious to see a lapped cooler as well just to make sure everything is making the best contact.

Have a request here, review the old school thermaltake big typhoon air cooler from back in the mid 2000's would love to see how it would do on modern cpus I suspect it was way ahead of its time, just a thought :-)

When you say the core to core delta goes down with direct die is that at a similar delta from ambient? Since you are cooling better all around the core to core delta could go down just because you are cooling everything better. I honestly feel like at least a fair portion of the delta has to be just due to the actual silicon and also the layout of the cores. Also it would be interesting to see if any of these things change which core is the hottest. I suspect the hot cores are staying the same through delidding and lapping, but you didn't really say.

If I could, yeah, I would definitely save a couple degrees.

Well Im doing a full custom loop with 2x360 rads and a waterblocked 3080 and 11900k. I thought about doing this to achieve the lowest fan speeds possible but 2°c I don't know if it's worth the effort and stress.

Those Bitcoins falling out of the computer case?? I didn't know that how it works.. HAHAHAH

That core to core Delta could be in the silicon itself. All tests had nearly the same lowest load temperature readings.

I think I already said this once but just to be sure I'll say it again. K|NGP|N really missed out on calling himself Count Clockula. He obviously looks like a vapire, especially with the samurai style hair.
