Weird to find a compromise in a no-compromise CPU. I wonder how much more Intel would have to charge per CPU if they used a tighter tolerance heat spreader for the massively high end CPUs only. If it doesn't matter for 99% of all chips okay, use the other process, but for that remaining 1%, it seems like billions of dollars of R&D could be bought cheaply simply by refining this one component. I hope someone with some power and vision at Intel watches this, since AMD is looking to eat their lunch again with Ryzen 7000 and they could use every advantage. Or someone at AMD could watch this, improve their own high-end and continue embarrassing Intel in the future.

[@satibel]

Tbh offering a "top bin" for the higher end CPUs at like 400 bucks more without an IHS or with a lapped IHS may be interesting. I wouldn't buy it but people looking for absolute best performance may want it.

[@RowanBird779]

Or, like, design the CPU to use a somewhat reasonable TDP? This thing draws more power than my entire computer

[@deepspacewanderer9897]

8 months old comment, but anyway, i think the issue may be that the cost may be higher than what the price of buying that lid would suggest and that in practical applications, as shown in the video, the gains are minimal to non-existant: 1)Because of the random factors during manufacturing process (and manufacturers designing around the existance of said random factors), you only get to know if any particular chip can be made into a top tier/mid tier/low-end processor after evaluating (i.e. (mostly?) testing) it. Which means that you have to either a)disassemble, clean and then reassemble already working processors (which, besides costing money, adds some risk of breaking them), b)or you have modify your production process to have your testing done before fully assembling the processors, which will probably increase production costs for all of the processors, which, given that only a very small percentage of the processors would actually use that super flat IHS, would effectively make installing that IHS an expencive process (if 100 processors with standard IHSs cost, lets say, 1000$ make and 99 "standard" and 1 "super flat" processors cost $1050, then that super flat IHS effectively costs 50$). 2)You now also have to manage having 2 similar items in your facility, which increases costs of running said facility (i.e. the production cost of all of the processors), which, same as above, means that it is, effectively, really expencive to store those super flat IHSs.

@@girlsdrinkfeck The game is not about heat dispersion for a long time now, CPU cooling is like 95% about heat transfer from the die/IHS to a few milimeters away.

Man, this takes me back to when I had a phase where I lapped the mating surface of my heatsink as well as the top of the IHS so there was less thermal compound needed to fill the gaps. I certainly didn't get a 10c improvement, but it was pretty cool to have a near-mirror finish on your CPU 😎 That was right in the era of having a DFI LanParty motherboard with UV reactive PCI slots.

Not too much difference, although it is probably a bit better. But consider that a copper heatpipe is about 20-200 times better thermally conductive, and you'll realize why hardly any coolers use silver. Ease of manufacturing and corrosion resistance of copper metal play a role too.

[@thunderarch5951]

Why yes, silver is 7% more conductive than copper(that in this case would at best give you a couple degrees less), it also costs 50 to 150 times more per pound Do I need to explain why it would be such a stupid thing to do, or you think you can manage that for yourself? Also, metal liquid is mostly gallium Silver and gallium make an alloy, Ag2Ga, that can happen spontaneously at room temperature This alloy increase its electrical conductivity, against its thermal one, enjoy

Few hints (from old delidder): 1. Cut the cotton part from ear-stick-cleaner and spread thermal grizzly with plastic sharp part (avoiding any cotton hairs that can stick in), and 2. Don't remove all glue from cpu pcb just gently clean it with isopropyle alchol, (it's okay to have part of it left on pcb) then apply medium-thin silicone glue / whatever you use. Tested many times, 100% best way. And gift tip ... dont wait too much for glue to settle, put in cpu socket and lock it, left it there to settle under pressure of locking mechanism, that way you get correct thermal compound distribution over cpu die + IHS.

The nickel plating on the IHS actually does significantly contribute to thermal resistance due to the nickel being heat-soaked.

I used copper shims to repaste my Alienware M15 R5. Ryzen 9 5900hx/3070 130w I used 20mm x .3mm for the GPU, and 15mm x .5mm for CPU. I have not seen the CPU over 83 since, and GPU hasn't been over 79. Those highest temps were during a back to back Time Spy/ Afterburner overclock session. 11,091 time spy score with it. This is my first experience with copper shimming. I used to have a computer that instantly throttled during anything more than web browsing.

I actually bought one of these back in 2019 and my temps did go down a good bit, I still have the excel file I made. The core temps went from (90/85/93/86) to (74/73/80/74) using whatever stress test I was using at the time (Probably Prime95).... So they do work pretty dang good.

You need to invest in a set of gauge blocks. If you can wring the IHS to a gauge block, then you know it’s flat. Same goes for the your coolers touch surface. Having a surface grinder with an aluminum oxide wheel, diamond honed, on had will let you be much more precise than the hand pressure wet wheel method seen before.

[@paulbrooks4395]

As electricity usage per square mm goes up, every additional improvement in tolerances will have greater levels of significance (obviously to a point). It’s clear that for the maximum performance units they could do better, but for the overwhelming majority of processors, thankfully, doesn’t matter. It does raise a question about the value of keeping the prices down on the high end products when quality suffers. Relying on 3rd party improvements has been standard for top-end systems, usually because of some odd deficiency-whether it’s lapping the IHS, package bending (Alder Lake), IHS-die gap (on the interior), de-lidding, die lapping, or use of liquid metal TIM-halo products could benefit from the additional effort, and we could still enjoy warranty coverage. I personally think paying more for better quality in a complete package off the assembly line is worth it for halo products. I would be willing to pay to not risk ruining something so expensive.

[@suntzu1409]

Better quality parts would really justify the KS name and price

[@halycon404]

Eh. Don't know. The price may not be worth it to them. Computers are not like any other product on the market. They depreciate so quickly. In a year or two the 12900KS will be outperformed by the rest of the high end market, in 5 it'll be outperformed by the majority of the market. Does it make sense for Intel to spin up entire new boutique divisions just for the KS series? I'd say no. A halo chip is for current headlines, it's not like a halo car which could have an impact on the brand for decades. People don't judge chip manufacturers on halo products. They judge them on what they can actually afford to buy. Chips are commodity priced and sold, which we saw over the last two years with the chip shortage. Noone has brand loyalty to Tropicana, if Tropicana OJ is out they'll buy store brand and be fine with it. With how fast chips depreciate it honestly may not be worth it to Intel.

I would be interested in seeing a direct die vapor chamber like in some GPUs and Laptops as an IHS. That would be a lot more thermally conductive than a pure metal IHS and spread the heat even better over the whole area of the IHS.

[@D3nn1s]

Actually im not sure it would be. Vapor chambers are used for long distance heat transfere like a laptop or aircooler. Pretty sure when you only need a mm or so that wouldnt even be possible that thin. Also youd transfere the heat from metal to vapor to metal again which should be worse than 1mm of copper i suppose. But im no expert just following my brains logic so pls correct me if theres an expert somewhere here

[@emmamitchell1582]

@@D3nn1s My feeling is that it may still be beneficial, especially as the whole area of the IHS will be more evenly used, instead of the heat being concentrated where the die is. But this discussion is what would make the experiment interesting! Please Alex/Linus!

[@starcraftkris]

Kind of a simple question. If the flatness / uniformity of the heat spreader is so important to the performance here shouldnt you have to enforce that same standard for the contact on the cooling device? In my experience those surfaces are far less uniform than any CPU side heat spreader I have ever seen.

[@FireFightJack]

6:00 Its a good idea in theory, but in my experience those tape guns are vastly inferior. They have another point of failure AND restrict the way you can use it. It may be fine for a couple of uses at home but try packing two or three hundred packages yourself in a day and you will know the difference. Just get the standard 3M tape gun without that "safety feature" and learn how to not cut yourself with your tools.

[@alexanderm2702]

Since it's soldered I think it would be about the same, it's not like the older CPU's that used some cheap paste. I think part of the difference might be the thickness of the copper lid. I have one of those (no name brand) for X series and the lid is about 2mm thick, vs maybe 0.5mm stock. More thickness would allow the heat to spread out more better from the CPU die to the rest of the IHS.
