Linus did the same a few years back with a much more expensive intel xeon processor and damaged it. Unsurprisingly intel refused to send a replacement then.
I actually find it insane that top of the spec products don't even, consider outsourcing cpu lids for a product that just only realistically exists because a competitor is outperforming you.
For real, I don't buy the explanation that manufacturers couldn't scale this up to mass production when they are producing chip dies that require far lower tolerances than machining smooth IHSs.
That and much more. Like guaranteed all core clocks for a specific voltage. Like siliconlottery did it. The KS series is like an amazing wagyu steak packaged in a terrible paper bag with holes in it. Something you might expect a pretzel to come in.
Burning the house down might raise the temp a bit more 10 degrees C (at first), but once you're rocking outdoor PC lifestyle, the Winter temperatures should let us get even more performance out of it.
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.
main issue with this is that cupper and gallium will react and liquid metal will "dry out". Maybe precuring cupper surface with LM will create layer of CuGa2 and it will not dry out anymore, but I did not test that.
I want to see how Silver which is more conductive than copper would perform. Like Linus and a few other youtubers could afford to show testing on Silver heatsinks. I guess it would perform 7% better than copper.
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.
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
What I really would have liked to see is just how much difference lapping the original IHS would have made before they removed it and installed the replacement IHS. They could also have tried delidding and replacing the solder with liquid metal to see if that made a big difference. As it is we don't really know if the improvement is because of a flatter IHS, using liquid metal as a TIM instead of solder, or if it's the new IHS that makes the most difference.
I remember back in 2013 when AMD brought out the R9 295x2 and Linus said that intel needed a product that pushed the bounds of what's possible and requires watercooling. Looks like he finally got his wish!
Everytime the CPU boosted higher with the temperature dropping. Now what I want to see is a situation in which the CPU doesn't draw more, to see the true temperature difference. Maybe limiting the CPU clock to whatever the stock CPU was running at. I think it should actually reach the 15°C mentioned online.
Also.. if they want to have a legitimate comparison, they probably should have used the same cooling system.. As impressive as the temp drop is, the fact that they used different coolers for the 2 stress tests invalidates everything in my eyes.
nah, nobody cares about the temp of your cpu. The purpose of cooling a cpu is to get more performance out of it, so testing the performance is literally what matters. If a cpu performs the same at 100c and 40c, why would you spend any amount of money to get it cooler? It's not going to help longevity either, you can run a cpu near tjmax it's whole life and you'll need to upgrade your cpu because it's slow as shit due to the time that has passed before anything actually happens to it.
2:52 Hey Linux, CNC machinist here ! The reason why a good surface finish like this costs alot is because we need specialised carbide inserts in the facing tools and alot of machining time to get such a finish. Specialised inserts for insane finishing capabilities are more expensive, as well as the tools to wield them. So its not really a question of a better machine or not, but more like better tools and more work time, therefore the value is higher.
This may not be the right place to say this but I want Linus and the whole team to know that the love of my life looked up to Linus and loved everything about you guys. We would watch your videos together, and he would explain everything because I'm not techy. He was taken from this world way too soon. Thank you Linus for bringing a smile to his face everyday. Every time you all drop something, too of course.
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. Wish I had pictures of that setup still!
Having the extra good heat spreader should have been the standard. Intel wants to pump the absurd extreme, they should offer supreme cooling. As if it's not expensive enough already, while there's almost no way to prevent it from throttling.
nhaaa, they should just rework their stuff, all they do is keep upping the power consumption gen after gen, just like ngreedia does. thats great if you live way north but having a space heater with 300w cpu and 400w gpu is the definition of ''playing on a toaster''.
@@jeromegagnon3787 it would be better if they made their general line up better, but it if they are going to make a hot part like this they'd better supply it with ample cooling.
The stock IHS is domed for a reason: To make sure it will work even with lower quality heatsinks and low quality thermal compound. You can get the exact same result as in the video by just sanding down the IHS flat.
@@jeromegagnon3787 one the many reasons I got a 75w Series S console....The next gen is gonna be 10X my S's 75w power usage. I will keep my old 200w PC for retro/media usage.
I just finished rendering 5,400 frames of 3D animation, a second less each would have saved me 1.5 hours of downtime so, under the right conditions, it's totally worth it!
Yes, though it's getting to a point where it would just make more sense to have 2 computers render 2700 frames each. Much faster. And after a point, or at a bigger scale it gets cheaper at the same time. Including the power costs.
Back in my day we’d just remove the heat spreader and mount the cooler directly on the die. Who knew that heat spreaders would become so good that you would actually want to mount a custom one to lower temps?
The nickel plating on the IHS actually does significantly contribute to thermal resistance due to the nickel being heat-soaked. The thin-wall assumption that you spoke of holds primarily for steep temperature gradients, but under nearly isothermal conditions, like a CPU and cooler at steady-state, the contact resistance of the nickel-to-copper interface is actually quite significant relative to the other sources of thermal resistance. I would cite my sources, but it was a textbook I read like 2 years ago and I can't remember what it was called, sorry folks.
I delided my 8600k, was a lot of fun. I didn't even bother glueing the IHS back on, I just used the mounting pressure of the socket to hold it still. I probably got like a 10c drop just putting the previous IHS back on with liquid metal and lightly planing the IHS + heat sink.
I've seen Linus complaining about sticky residue several times. Tech tip: contact cleaner dissolves sticker and glue residue like it is nothing. You can even remove void warranty stickers with that stuff. Just be sure to use the computer-kind contact cleaner. Automotive contact cleaners sometimes use minute abrasive agents that can ruin the look of some plastics :(
What you could use to measure it is an optical flat and a low pressure sodium lamp that measures surface flatness by optical interference. It sounds complicated but if you set it up right it's actually pretty simple.
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.
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.
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.
Actually, silver metal has the best thermal conductivity of any metal at 429 W/mK. Gold is 310, copper is 401, aluminium is 205. The thermal conductivity of a copper heatpipe is between 10000 and 100000 W/mK. So a gold heatsink would make no sense at all.
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.
1:22 y'all pretty much explained Six Sigma manufacturing better than any corporate trainers I been subjected to 🤣 so considering that Intel isn't realistically expecting a perfect finish, I'd take a guess they're wanting an adequate finish and Sigma 3 or 4
6S is even more cringe than 5S. All lean manufacturing is soooo painfully cringe. The proponents and the consultants are the type of people that pump 6S during the work week, and a -pyramid scheme- ... I mean MLM scheme... after hours and on weekends. You'll see them at MLM rallies on Saturday afternoons.
I love Alex's semi-disapproving parent look throughout this video, as Linus drops the CPU multiple times and makes a mess, to the point where Alex just takes over.
@modest mouse colored person he has completely flanderized himself, "this computer legitimately if you have like bad not up to code wiring in your house it might burn down" his schtick has really lost all of its charm.
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.
The time consuming part for keeping the tolerances so tight isn't the machine itself nor it's quality (well to a degree on quality of the machine) but the frequency you have to check tolerances and change the tool wear in the settings of your machine, as well as how you mount what you're machining, depending on what you make you may have to choose between something that gives extraordinarily repeatable results and has no play or something thats fast, just depends on what you have to work with because your fixture is definitely important
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.
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.
Pah, heatspreaders! Back in the days we had raw and open CPU cores which we'd chip corners off when putting the heat blocks on! Looking at you, AMD Athlon XP Series!
I feel like changing thermal pads/paste on the gpu may have actually seen results in this setup. My 3090FE had massive cooling gains for memory temps when I did it (about 20 degrees cooler), I think they really have been skimping in the thermal pads.
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.
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
@@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!
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.
I loved the 12900ks - recently sold it. Now I have the 13900k & 14900k. For those worried about temps/degradation: For my 13900k and 14900k I have done the following: MCE off, PL1 and PL2 limit to 225, limit P-core boost to 5.5 GHz and E-core boost to 4.3GHz, and use balanced power profile in Windows (although I do disable core parking to keep system highly responsive). Oh and just XMP on the RAM. I didn’t change LLC value. I have set voltage offset at a modest -0.010v. I have disabled the C6&C7 C states and EIST. Lastly I have locked AVX at 0 offset. I have tested on P95, CB R23 and CB R15. All great and in a mid 20 degree room, no workload exceeds 80c on package or cores just using an NH-D15 with an airflow case. Very happy and benchmarks are very close to where they were before taming these beasts.
6:01 It's these sorts of things that make you realize Linus is really savvy when it comes to tech, but he can be truly clueless when it comes to "normal" stuff lmao As if it's the first time in his life he has to deal with a tape dispenser...
to be fair, that is a crappy tapegun design to use. esspecially when typical use and abuse happens to break off the top flap and the whole gun is unusable now.
@@Dreddy72 As someone who has to send packages on an almost daily basis, this Staple's tapegun is fine and virtually impossible to break by accident, you'd need to try and break it on purpose. And I'm no gentleman when it comes to taping packages...
Here's an idea for cooling experiment. Lap that IHS and a cooler for a perfect flatness on both surfaces to see if you don't need thermal paste. You could also try to attach the cooler to the ihs in vacuum to make a cold weld contact.
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.
I put one of these on a 8700K a few years back, dropped temps by about 15C at idle, and allowed me to push it to 5.2GHz, which was pretty fast at the time.
Windows 11 is shit and will remain shit throughout its life cycle. Windows 12 will be built on windows 11 with all bugs cleared out and new futures polished. It happens every cycle.
Maybe, but so does Linux. And honestly, I don't really care anyway. Fuck Windows 11. I'm not running it. And fuck 10 too for that matter, although that's not relevant at the moment.
wym only linus, i know plenty of people who delidded their 12900k*, the temperature gain on the rocket ihs is not worth it though, you can just polish the ish that comes with the cpu to get around the same performance
@3:19, They interpret they are interpreting the spread of the thermal compound on the heat sink incorrectly. It actually was making better contact on the center leaving more thermal paste on the CPU and was less effective on the sides. JMO.
10:40 nope, you're not tried hard enough to get perfect temperatures... To do this you should sanded the heatspreader and water block up to perfect flatnnes and shine ☝️
Intel should definitely still be worrying themselves later this year, now that AMD is fully switching to LGA and potentially brining their 3D cache tech and RDNA2 UHD graphics to do anything into one. After them realizing they’ll be able to break their limits of DDR5 speeds too like XMP, but more insane
I believe Intel themselves will be bringing upgrades with double the small cores alongside higher performance for the big cores. AMD will most likely take the gaming crown while intel workstation crown.
Honestly, lga1700 motherboards are ridicolously expensive when compared to AM4, especally at the lower end. And I expect similar pricing for AM5 boards, because of PCIE gen5 and DDR5 as well as being the hot new shit. Soooo Ryzen might be a king in performance, but could lose on the value front.
For the next extreme cooling episode I'd like to see whole loop liquid metal cooling. Sodium and potassium form an alloy that starts being liquid under 0 degrees C (depending on the Na/K ratio), it doesn't corrode copper, works well with glass, can be pumped without any moving parts using just electricity and magnets (look up magnetohydrodynamic pump). Only problem is that it burns on contact with air or water, so the loop (most likely rigid glass loop) would have to be assembled using an inert atmosphere (welding argon should suffice). Old (and I mean Nixon old) nuclear reactor whitepapers on NaK cooled reactors and how to handle the stuff are available online.
15:50 If your wiring is not up to code this might make it burn down. Eh maybe if you have aluminum wiring from the 1960's-1970's. If you have copper wiring, it's doubtful that you have anything better than than 12 AWG.
i think a more 'accurate and scienfitic' method would be like der8auer did - measuring the average thickness of the thing with a micrometer and evaluate a standard deviation. Just measure like 20-50 spots on the heat spreader and compare the standard deviation to the copper one.
Linus and LTT you should try IHS's made of silver, 24k gold, niobium, and other metals in your new lab. you can get a jeweler to make them using a CNC or laser I would recommend Riva Precision Manufacturing in Brooklyn NY but I know they deal mainly with large orders but I can definitely help you find a jewelry in your area with the right equipment to do it
Very interesting video! I wouldn't have expected an aftermarket part like that to produce that much of a drop in temps. Curious bit of product placement with the Dell laptop though, haha!
I really would love to see this, too!!! For me the pump will be the most problem, because liquid metal doesn't stay always liquid, especally in regions/parts with many movement and friction. Also I don't know if the liquid settle down on some materials and cause a clog after a while. But this experiment would be awesome!!!
No point, it can only perform worse. The point of liquid in a liquid loop is to move heat away from a point, so you need thermal mass. Water has higher thermal mass than liquid metals, by quite a bit. Add on the reduced flow, clogging, etc...
1:36 Ohhhhh Linus, don't do this! Unless you want to stab your own hand, I recommend not applying force to a sharp-ish object in the direction of your flesh, especially when that force may cause the object to jump and stab your hand. Tried it, wasn't nice.
well it certainly is more extreme than your regular water n shit and this video is about taking a possible daily runner PC to the very max (although I'm not sure they used the biggest still reasonably sized rad).
If my materials science knowledge is correct, the nickel plating if anything protects the copper from oxidizing in the few years the processor will still be competitive. Oxide layers tend to have different thermal and mechanical values.
3:39 Intel after buying multiple $5000 setups for LTT staff, and even letting Linus make a video inside their "ultra secret" CPU factory, but still getting called "what a bunch of jerks" literally just 2 days later: "You know how much I sacrificed?!?!?"
@5:00 what shocks me is that intel doesn't just sell CPUs delidded for people to just buy. They would save/make more money by selling them at the same price since they can skip a few steps and it would save buyers time and money too.
Copper doesn't react well with liquid metal, it absorbs some of it and creates a thin layer of gallium on the outer surface. That is why people usually only put liquid metal under the IHS and not over it as the IHS is nickel plated but the CPU coolers are usually not and are just bare copper. But in this case it doesn't really matter for them if they are going to stain the cooler so they could have put liquid metal on top of the IHS as well. Liquid metal has way better thermal conductivity than even the best pastes. If they were going for the very best performance they could have direct die cooled it as well.
Would love to see you guys make a pefect copy of the IHS out of solid silver for that extra couple degrees. The stock metal would prob cost less than what you paid for this

@@FranciscoTChavez i like how you are thinking
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.
main issue with this is that cupper and gallium will react and liquid metal will "dry out".
Maybe precuring cupper surface with LM will create layer of CuGa2 and it will not dry out anymore, but I did not test that.
I want to see how Silver which is more conductive than copper would perform. Like Linus and a few other youtubers could afford to show testing on Silver heatsinks. I guess it would perform 7% better than copper.
Wouldn't it bend?
Diamond - 2000 - 2200 W/m•K... They should Use Diamond 💎. Better than Silver 5x times 🤣😅
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.
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
just looked into that and seems like it would need some sort of plating cause silver alloys with gallium which is in liquid metal, which would ruin it

What I really would have liked to see is just how much difference lapping the original IHS would have made before they removed it and installed the replacement IHS. They could also have tried delidding and replacing the solder with liquid metal to see if that made a big difference. As it is we don't really know if the improvement is because of a flatter IHS, using liquid metal as a TIM instead of solder, or if it's the new IHS that makes the most difference.
The stuff they used to get rid of the solder is actually a Gallium, Indium, and Tin alloy called “Galinstan”.
I remember back in 2013 when AMD brought out the R9 295x2 and Linus said that intel needed a product that pushed the bounds of what's possible and requires watercooling. Looks like he finally got his wish!
Damn even the single R9 290 was a mess to cool. Been running in thermal throttle since day one, had to build my custom WC loop
@@bratisla2040 I had a Tri-X 290 for a while back then. After repasting, it didn't go past 75 degrees EVER.
Everytime the CPU boosted higher with the temperature dropping. Now what I want to see is a situation in which the CPU doesn't draw more, to see the true temperature difference. Maybe limiting the CPU clock to whatever the stock CPU was running at. I think it should actually reach the 15°C mentioned online.
Limit the CPU clock in both tests, that way all factors will be the same.
I think this is really what they should have done before thinking about 20W extra, higher clocks, overclocking or whatever
Also.. if they want to have a legitimate comparison, they probably should have used the same cooling system..
As impressive as the temp drop is, the fact that they used different coolers for the 2 stress tests invalidates everything in my eyes.
@@MasterOfNone585 I think they used the same setup for both.
nah, nobody cares about the temp of your cpu. The purpose of cooling a cpu is to get more performance out of it, so testing the performance is literally what matters. If a cpu performs the same at 100c and 40c, why would you spend any amount of money to get it cooler? It's not going to help longevity either, you can run a cpu near tjmax it's whole life and you'll need to upgrade your cpu because it's slow as shit due to the time that has passed before anything actually happens to it.
Linus: "I can't believe we're already doing this"
Me: "I can't believe Linus is letting himself handle it already"
2:52 Hey Linux, CNC machinist here !
The reason why a good surface finish like this costs alot is because we need specialised carbide inserts in the facing tools and alot of machining time to get such a finish. Specialised inserts for insane finishing capabilities are more expensive, as well as the tools to wield them. So its not really a question of a better machine or not, but more like better tools and more work time, therefore the value is higher.
10 extra lower degrees of temp for just 40 dolars is actually amazing
This may not be the right place to say this but I want Linus and the whole team to know that the love of my life looked up to Linus and loved everything about you guys. We would watch your videos together, and he would explain everything because I'm not techy. He was taken from this world way too soon. Thank you Linus for bringing a smile to his face everyday. Every time you all drop something, too of course.
So sorry to hear, but it’s comforting to know that LTT could be a way to reconnect with those memories.

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. Wish I had pictures of that setup still!

@@DarthCiliatus which in it's turn takes 2kw of power and has issues with condensate
Having the extra good heat spreader should have been the standard. Intel wants to pump the absurd extreme, they should offer supreme cooling. As if it's not expensive enough already, while there's almost no way to prevent it from throttling.
nhaaa, they should just rework their stuff, all they do is keep upping the power consumption gen after gen, just like ngreedia does. thats great if you live way north but having a space heater with 300w cpu and 400w gpu is the definition of ''playing on a toaster''.
@@jeromegagnon3787 it would be better if they made their general line up better, but it if they are going to make a hot part like this they'd better supply it with ample cooling.
@@Olav_Hansen id rather it come with an ac unit then. the part can stand the heat, i don't .
The stock IHS is domed for a reason: To make sure it will work even with lower quality heatsinks and low quality thermal compound. You can get the exact same result as in the video by just sanding down the IHS flat.

@@matejnemec4616 a second less per frame is worth it, either on cpu or gpu --for this video the upgrade was cpu cooling anyway, not the actual cpu
Makes you think about having one of those coppers on your GPU, and putting the whole thing in an actively-cooled liquid bath, to me.
@@davidgoodnow269 precisely! especially considering how sensitive are gpu clocks to temperature these days
Yes, though it's getting to a point where it would just make more sense to have 2 computers render 2700 frames each. Much faster. And after a point, or at a bigger scale it gets cheaper at the same time. Including the power costs.
Back in my day we’d just remove the heat spreader and mount the cooler directly on the die. Who knew that heat spreaders would become so good that you would actually want to mount a custom one to lower temps?
AMD Athlons/Durons are welcoming you ^_^
The nickel plating on the IHS actually does significantly contribute to thermal resistance due to the nickel being heat-soaked. The thin-wall assumption that you spoke of holds primarily for steep temperature gradients, but under nearly isothermal conditions, like a CPU and cooler at steady-state, the contact resistance of the nickel-to-copper interface is actually quite significant relative to the other sources of thermal resistance. I would cite my sources, but it was a textbook I read like 2 years ago and I can't remember what it was called, sorry folks.
I delided my 8600k, was a lot of fun. I didn't even bother glueing the IHS back on, I just used the mounting pressure of the socket to hold it still. I probably got like a 10c drop just putting the previous IHS back on with liquid metal and lightly planing the IHS + heat sink.

I've seen Linus complaining about sticky residue several times. Tech tip: contact cleaner dissolves sticker and glue residue like it is nothing. You can even remove void warranty stickers with that stuff.

"intel's worst product"
Intel: hold my beer makes 14900k
It would be interesting to send the intel IHS to a company that can test its “flatness”.
Its most likely slightly bend now after the delidding.
Why? The real issue is how inconsistent Intels IHS are from one unit to the next. Some might be flat while others arent.
@@randybobandy9828 There is also the issue, on 12th gen specifically, of the Independent Loading Mechanism (ILM) bowing the IHS.
GN tests that.
What you could use to measure it is an optical flat and a low pressure sodium lamp that measures surface flatness by optical interference. It sounds complicated but if you set it up right it's actually pretty simple.
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.
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.
Or, like, design the CPU to use a somewhat reasonable TDP? This thing draws more power than my entire computer
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.
If gold is also an excellent conductor, well I think you gotta test the theory of gold vs copper
Gold is worse in thermal conductivity. By quite a bit.
Actually, silver metal has the best thermal conductivity of any metal at 429 W/mK. Gold is 310, copper is 401, aluminium is 205.
The thermal conductivity of a copper heatpipe is between 10000 and 100000 W/mK.
So a gold heatsink would make no sense at all.
@@ProjectPhysX So... silver coolers when?
A diamond IHS is the way to go
@@Sithhy for a top price CPU silver heatsink actually makes sence. However if you running water cooling, you want to stick to a mono-metal system.

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.
Those tape guns may be required by Canadian OH&S.
1:22 y'all pretty much explained Six Sigma manufacturing better than any corporate trainers I been subjected to 🤣 so considering that Intel isn't realistically expecting a perfect finish, I'd take a guess they're wanting an adequate finish and Sigma 3 or 4

I love Alex's semi-disapproving parent look throughout this video, as Linus drops the CPU multiple times and makes a mess, to the point where Alex just takes over.
@modest mouse colored person he has completely flanderized himself, "this computer legitimately if you have like bad not up to code wiring in your house it might burn down" his schtick has really lost all of its charm.
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.
What cpu did you put it on?
It'd be pretty crazy to see some emulation with this CPU
Yeh
technically any interpreted programming language is emulation
The time consuming part for keeping the tolerances so tight isn't the machine itself nor it's quality (well to a degree on quality of the machine) but the frequency you have to check tolerances and change the tool wear in the settings of your machine, as well as how you mount what you're machining, depending on what you make you may have to choose between something that gives extraordinarily repeatable results and has no play or something thats fast, just depends on what you have to work with because your fixture is definitely important
you know when there's tasks requiring dexterity, we're going to get a Linus Drop Tips special, lol
7:00 It's nice that Linus mentioned us: Polish people also watch LTT.
English is so confusing to foreigners. 🤣
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.
Better quality parts would really justify the KS name and price
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.
Pah, heatspreaders! Back in the days we had raw and open CPU cores which we'd chip corners off when putting the heat blocks on! Looking at you, AMD Athlon XP Series!
by the time i desolder the IHS, why not do direct die cooling?
paying 80$ more for a special waterblock sounds way easier at that point
15:27 The wallpaper is hilarious 😁😁
And I love that intel sponsor’s LTT no matter what
But Intel didn't sponsor them, they were sponsored by Build Redux and Ting
I would love to see this compered to a direct die 12900ks in terms of temperature
This plus lapped OEM IHS. I wanna see how much the flatness is a contributing factor.
Love the little edit when Linus says perform surgery... "on a grape"
I feel like changing thermal pads/paste on the gpu may have actually seen results in this setup. My 3090FE had massive cooling gains for memory temps when I did it (about 20 degrees cooler), I think they really have been skimping in the thermal pads.
6:48
Linus: Gotta say, the little tissues I dispose of usually don't look like this.
Alex: Sighs like never before.
Linus has some on point jokes sometimes LOL
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.
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
@@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!
@@emmamitchell1582 Dennis is right here, heat pipes work well over several cm plus. Thinner than 3mm and straight copper is objectively better.
@@D3nn1s
Ehhhh heat pipes are used for long distance heat transfers
Vapor chambers are used for large area heat transfer
Or is it?
Vapor chamber is when you want to transfer heat across a huge surface area
what would be the temperature from just delidding the CPU and putting liquid metal under the stock IHS? Would be nice to know for comparison
Not much. Der Bauer (der 8auer) already tested it on his channel some time ago ^^
@@StitchExperiment626 did He? I only found the Video where He killed his 12900k
I'm also curious about how this aftermarket IHS performs compared to a lapped stock IHS
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.
I loved the 12900ks - recently sold it. Now I have the 13900k & 14900k. For those worried about temps/degradation: For my 13900k and 14900k I have done the following: MCE off, PL1 and PL2 limit to 225, limit P-core boost to 5.5 GHz and E-core boost to 4.3GHz, and use balanced power profile in Windows (although I do disable core parking to keep system highly responsive). Oh and just XMP on the RAM. I didn’t change LLC value. I have set voltage offset at a modest -0.010v. I have disabled the C6&C7 C states and EIST. Lastly I have locked AVX at 0 offset. I have tested on P95, CB R23 and CB R15. All great and in a mid 20 degree room, no workload exceeds 80c on package or cores just using an NH-D15 with an airflow case. Very happy and benchmarks are very close to where they were before taming these beasts.
Update: I have now undervolted to -0.015v and set the Core limit to 300 Amps.

Here's an idea for cooling experiment.
Lap that IHS and a cooler for a perfect flatness on both surfaces to see if you don't need thermal paste. You could also try to attach the cooler to the ihs in vacuum to make a cold weld contact.
^^ *THIS* ^^
_Vacuum_
I thought the thread ripper consuming crazy wattage was nuts. Thanks intel!
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.
I put one of these on a 8700K a few years back, dropped temps by about 15C at idle, and allowed me to push it to 5.2GHz, which was pretty fast at the time.
Same here and I'm using a relatively small Noctua cooler. Still seems like I bought the 8700K yesterday.

Intel should definitely still be worrying themselves later this year, now that AMD is fully switching to LGA and potentially brining their 3D cache tech and RDNA2 UHD graphics to do anything into one. After them realizing they’ll be able to break their limits of DDR5 speeds too like XMP, but more insane
Why would Intel be worried about AM5 being LGA?
Man that's gonna push Steam Dieck stonks to the roof.. Hell yeah
I believe Intel themselves will be bringing upgrades with double the small cores alongside higher performance for the big cores. AMD will most likely take the gaming crown while intel workstation crown.
Don't know how lga should make them worried, but 3d cache still needs more work. They won't implement it on R7000
Honestly, lga1700 motherboards are ridicolously expensive when compared to AM4, especally at the lower end. And I expect similar pricing for AM5 boards, because of PCIE gen5 and DDR5 as well as being the hot new shit.

For the next extreme cooling episode I'd like to see whole loop liquid metal cooling. Sodium and potassium form an alloy that starts being liquid under 0 degrees C (depending on the Na/K ratio), it doesn't corrode copper, works well with glass, can be pumped without any moving parts using just electricity and magnets (look up magnetohydrodynamic pump).
Only problem is that it burns on contact with air or water, so the loop (most likely rigid glass loop) would have to be assembled using an inert atmosphere (welding argon should suffice).
Old (and I mean Nixon old) nuclear reactor whitepapers on NaK cooled reactors and how to handle the stuff are available online.
When every component costs more than your entire pc:
15:50 If your wiring is not up to code this might make it burn down. Eh maybe if you have aluminum wiring from the 1960's-1970's. If you have copper wiring, it's doubtful that you have anything better than than 12 AWG.
Also that applies to the countries with the 120V electric system.
240V countries are fine.
i think a more 'accurate and scienfitic' method would be like der8auer did - measuring the average thickness of the thing with a micrometer and evaluate a standard deviation. Just measure like 20-50 spots on the heat spreader and compare the standard deviation to the copper one.
I'd like to see a mid - high performance build with a focus on low electricity usage as electricity its getting expensive in some areas of the world
AMD is your friend on that regard

Very interesting video! I wouldn't have expected an aftermarket part like that to produce that much of a drop in temps. Curious bit of product placement with the Dell laptop though, haha!
Alex has been using the Dell XPS as his daily driver laptop for a long time now.
They should have used a MacBookAir as the laptop, just to tweak people... :)
Ok now this would be incredibly expensive, impractical and possibly even hazardous and component breaking but could you fill a loop with liquid metal?
I really would love to see this, too!!! For me the pump will be the most problem, because liquid metal doesn't stay always liquid, especally in regions/parts with many movement and friction. Also I don't know if the liquid settle down on some materials and cause a clog after a while. But this experiment would be awesome!!!
No point, it can only perform worse. The point of liquid in a liquid loop is to move heat away from a point, so you need thermal mass. Water has higher thermal mass than liquid metals, by quite a bit. Add on the reduced flow, clogging, etc...

it matters more when closer to the cpu. after the spreader, the contact area is increased.
@@arkie87 you would be surprised
Copper doesn't react well with liquid metal, it absorbs some of it and creates a thin layer of gallium on the outer surface. That is why people usually only put liquid metal under the IHS and not over it as the IHS is nickel plated but the CPU coolers are usually not and are just bare copper. But in this case it doesn't really matter for them if they are going to stain the cooler so they could have put liquid metal on top of the IHS as well. Liquid metal has way better thermal conductivity than even the best pastes. If they were going for the very best performance they could have direct die cooled it as well.

Would love to see you guys make a pefect copy of the IHS out of solid silver for that extra couple degrees. The stock metal would prob cost less than what you paid for this
