We sat down with Der8auer for a 15-minute video, but ended up with 50 minutes of conversation -- so we're splitting them into a few videos. This one focuses on marketing of thermal paste and interfaces, specifically highlighting thermal conductivity values. We spoke about W/mK values and their misleading nature (for pastes) in the past, but now we're revisiting it with additional ranting from Roman of Thermal Grizzly.

(And because we didn't expand on it here: Under identical test conditions or for base material properties, thermal conductivity is of course a real thing and is useful -- say comparing aluminum to copper -- but it's when you start making pastes and tuning the properties just for a marketing number that Der8auer needs an anger translator!)

Well its not something JDEC can step in and solve
We just need to hope that manufacturers start to do the test at 95c and base the specs sheet off of that
Because we have moved from CPU’s ramping up over time to them ramping down instead
Hence pegging at 95c and so the paste needs to be spec’ed for 95c
No mentions of thermal resistance. Still remember - Kryo33 made a point (they probably have a lab you talked about) that paste does not contain silicone, or any additives, and viscosity comes from finesse of the material, and, I speculate, that smaller the grains > closer to each other > better thermal transfer, because role of paste is not to conduct, but to transfer the heat. Often parameters come in two values conductivity and resistance - such as conductivity 13W/mK, thermal resistance
Had my sister use household lubrication mineral oil as "paste" on a CPU for 3+ years, because she is living in annother country and was unable to get her hands on real paste. So, I talked her trough all steps of building a PC and she did not have thermal paste. It was a custom "as cheap as we can make it, but new parts" office PC and I could not visit her. It is still running, albeit she did buy some paste after a few years and applied it.
I am a big fan of liquid metal. Used it on my AMD K6-2 the first time. Loved it. But yeah, there is a lot of fancy talk about heat paste, which a lot of people do not need. Even for overclocking gamers it is better to get a good paste and refresh it after a while, instead of getting the "best of the best" and never touch it again.
I miss the nerdy OC forums, which tested all the waterblocks, heat pastes and cascading compressor cooling solutions, with zero bias.
There's also thermal pump out that can occur that most reviewers won't see in the short term.
@@Niko-qk3su smaller particle size can only do so much as its fully bottlenecked by the carrier material and how many of those particles even actually touch each other

Yo! Thank you for being so kind after I ran into you at the airport and said hello. I appreciate the welcoming hello.
Thanks for saying hi and for watching the content!
Der8auer's channel has some fantastic content, especially for higher-level enthusiasts. He's also an actual engineer, so some of his commentary can get pretty involved and nuanced (as you see here) so prepare to have a second window open for WIkipedia~
I love how he talks a lot about engineering stuff in some of his videos, it really gives an unique touch to them. One of the tools he used to test a coldplate costs 7000 euros, lol, true engineer stuff.
Recently did a PowerColor GPU factory tour.
Just remember he split English and German videos to different channels.
"der8auer spelled mit Acht" This is very important and we should only call him like this from now on
I thought his name is called as Der AchtAuah, learning that it was Bauer messed it up for me
What does it mean? Is it “at eight”?
@@Quizack It means he replaced the "B" in "Bauer" with a number 8.

Wow that ended so fast, I feel like I need the uncut 50 minutes.
Good to know that thermal conductivity numbers are about as useful as TDP numbers. Just make everything up to get numbers you like!
Vote for uncut 😮
THANKS STEVE!
Thanks Roman!
Hydronaut hits all that and then some. and easy to apply
@@warpedphreak how is hydronaut different than kryonaut? I've heard of both but idk what the difference is
arctic
@@TheAechBomb kryonaut was designed for sub zero cooling, and it excels at that, but people usually don't daily drive sub zero, and instead frequently change the heat sink and repaste, meaning that they didn't need to design kryonaut for longevity. I don't know exactly how long it remains in an uncracked state, but it's very short compared to pastes that are designed for long term use, such as hydronaut.
@@insu_na Interesting and very useful reply to a question I didn't ask but did need the answer to, thankyou! Glad someone asked it too!
You guys have such good chemistry. Always a joy to watch you guys.
can't say it enough, these 2 need more content together.
"Der Bauer mit Acht" i lol'd heartily
Two of my favourite tech channels right there! The amount of amazing knowledge that you two (and your teams) have shared with the community is just incredible. Thank you for helping to make me an informed consumer. Just 3 years ago I had never built my own PC, but then I started watching tech channels like GN, Der8auer, LTT, and Level One Techs, and now I’ve built two with my own hands! Learned so much about form factors, platforms and their chipsets, CPU and GPU architecture, PSUs and their safety features/certifications, basic wiring of connectors, PCIE generations and specs, and even how TIMs work. I can’t overstate just how much I’ve learned from you two. Thanks so much Steve and Roman! Back to you Steve!
Misleading and marketing go hand in hand.
Not always. Some of the most effective marketing in this industry is based on just actual fact. Noctua, as an easy example, is famous for its focus on performance and letting performance and engineering sell the brand. It works. It's just not common because it requires more difficult-to-acquire skills.
@Gamers Nexus I've taken a more jaded view of this because for every good example (Nocuta) you have 10 more bad ones. Not discounting the good but acknowledging the majority. Cheers!
@@GamersNexus They'd sell more if their fans weren't "baby poo brown"... they are really good performance wise though!
I agree with Gamersnexus here. In big industries, people would only do very conservative figures as it can go south very quickly.
The company I worked for would always understate the machine capacity (they would be like around 10% below with additional cuts based on the expected down time per day)
@@RogueWraith909 I feel like they sell at all BECAUSE they're "baby poo brown", tbh. It's not like Noctua hasn't done black fans before. Turns out few people cared about those because everyone's already associated Noctua with the "baby poo brown", and it's unique compared to the millions of "more marketable" black and RGB fans out three.
I hope you will upload full conversation. It’s always good to hear two enthusiast talking.
Thermal conductivity has a very common standard using astm D5470 which is similar to the use case. The supplier should note the standard used. Laser flash and other metroligies are basically random number generators.
Also, the number that matters is thermal impedance. Thermal conductivity is better number for heat spreaders while impedence tells you how good of a tim the material is.
These things are true but lab results communicated ineffectively to end users who are not sophisticated and only want to know "does it work?" "How long?" "Is it easy to use?" and of course "price?" just do not help overmuch.
Standards can be misused as well as correctly used. Sometimes the guy who wants to build a computer just wants IT TO WORK OKAY.
That I think is probably the largest segment of the market.
@@phlogistanjones2722 the largest segment of the market is OEMs and ODMs. Selling to individual builders is barely any market share.
@@CutaneousSensationsI would argue that the same points that matter to consumers matter even more to OEMs and ODMs, longevity, ease of application, dangers like with Liquid Metal and how it’s conductive electrically, and price. For average Joe those things matter but less, I’d spend 30$ more to get 2deg C and have to spend an extra 10min applying it, for an OEM that just won’t do when they are looking at fractions of Pennies in their build. If I was an OEM I would look #1 at longevity, needs to be at least 5 years, next pick the top 5 lowest priced pastes that fit that criteria and trial a couple units of each in my existing assembly process and evaluate the results. Then I would go with the cheapest finest paste that performs well enough to stay within the cpu manufacturer specs for temperature.
@@radugrigoras all suppliers worth their salt do provide basics understanding on how their materials survive for 1008 h bake at 125c, temperature cycle B 1000 cycles, and uhast 85/85 1008h. Sadly this will not translate directly and the OEM/ODMs will have to verify it in their test vehicles and products since the use conditions will be unque. So basically they already do that. Only small material suppliers don't provide this data.
@@radugrigoras also, you are crazy to think they don't try to find the cheapest paste that will meet their minimum requirements. That's their goal. They work with the material suppliers to develop this.
Steve, you are an amazing person, with a goodwill, the amount of work you make for us is outstanding. Best wishes for you, thanks for everything you're doing!
Met Der8auer few years ago at Gamescon and he gave me a signed delidded 7700k chain, free ifixit kit and a hug, super nice guy.
After I got a new CPU I tried to put that IHS on my old 7600k because reasons, didn't go to well.
What a great dude! Roman always seemed like such a cool guy to me, so I’m happy to hear he’s like that IRL. What a shame the IHS transplant didn’t work though.
Here they are!
I was waiting for this video :D
Now I hope there's a video with Gordon too!
love derbauer! great content
I love watching stuff like this, getting the little bit of understanding from the people engineering something. Can't wait for the other parts.
4:15 I was actually wondering exactly this when I was shopping these, why some products didn't have thermal conductivity numbers. Glad you covered it!
I like Der8auer, a smart young fellow, I am subscribed to his channel.
He is spot on about manufacturers picking a sweet spot for their products out of the minimum to maximum 'Curve' , to make it look like it's the best.
Cool discussion / video .
Cheers
It stands to reason that they want to cast their product in the best light possible. No one's out there saying buy our stuff because it sucks unless they're selling vacuum cleaners.
I bought Thermal Grizzly paste with the thought of “If it’s good enough for overclocking it’s good enough for me”It was also part of the preparations for a planned Pc upgrade that never ended up happening.
If you're not overclocking or running a beast, any of the aftermarket pastes will be far beyond "good enough".
At that point, it's worth getting stuff for alternate specs, like longevity or ease of use or cheaper price.
@@ashkebora7262 I was planning on upgrading to a 12900k (the 13th gen wasn’t released yet) at the time I bought it, but that never ended up happening. And so I now have an I7 8700 with an overkill cooling solution. Better than letting the money go to waste. Maybe when my financial situation gets better again I’ll get a 9900k and overclock that. At least my CPU stays cool even with my room being nearly 40*C during summer 😂
@@Anonymus-ih7yb ahhhhh, I see. Yeah, running a 12900k definitely counts as planning on running a beast!
Ahh well, it'll hopefully at least last longer. I also try to overkill cooling, as unnecessary as it is for a lot of CPUs.
Though with how power-dense the tiny cores are getting these days, it's arguably _always_ a good idea to use as good of a paste as you care to afford, even if it won't need 200W+ of total cooling.
you 2 are my favourite tech youtubers!
I have been waiting the entire Computex for this!!! BEST BROMANCE ON TH-cam!
Computex 2023 was what was needed!
So glad to see many of my tech reviewers able to share space and ideas.
Especially after the last few years on this planet.
Very interesting talk, i loved the video. A little different but also very useful!
-Thermal conductivity values will tend to decrease with increasing operational temperature. Though in ranges of 20-100 C they may increase before decreasing at higher temperatures (this can be somewhat material dependent however)
-High thermal conductivity values are reported for solid sheet based TIMs usually because they are composed of graphene or graphene-based materials. The issue with this value is that graphene has exceptional thermal conductivity IN THE PLANE of the 2D graphene lattice. But thermal conductivity NORMAL to the graphene plane is significantly lower.
-The reason that the solid piece of copper interfaced with the heat source has approximately the same thermal conductivity as the heat source is based on the heat transport. You can think of the system as a multi-compartment system with a rate of heat flux for the thermal paste and another rate of heat flux for the copper sink, the reason the SYSTEM has the same heat flux rate as the paste is that it is the rate determining portion of the heat transport process. Like comparing flow rates of water through chicken wire fence versus a fine mesh.
-The thermal conductivity of the copper in silicone oil paste being low is based on, once again the rate-limiting process, which is heat transport through the silicone oil (silicone oil has a much lower thermal conductivity than copper). Increasing particle size of the dispersed metal increases thermal conductivity by increasing interfacial contact area between the heat source and metal, and sink and metal, and will be dominated by the high thermal conductivity of copper. Past a certain particle size however, you will see a decrease in interfacial contact area between the TIM and the surfaces of the parts (since the larger particulate will not easily fill the micro voids and imperfections in each surface).
-I'm not sure what they meant by the delta between the cooler and die, if its the separation distance though, thermal conductivity is a measure of Watts per Meter * Kelvin. The meter refers to the thickness of the material through which heat transports. So it follows that if you are transporting heat through a greater thickness of the same material, that the thermal conductivity will decrease.
(insert "thanks Steve" meme here) I love these collaborations, specially this way, chill and comfy, even more, as friends, making the videos very enjoyable, beyond the informative content. Thank you guys! Successes and blessings!
Respect is earned. der8auer is famous for good reason. This was an excellent video and needs further explanation with GN styled charts. 😀
data has been out there a long time. wtf you schmucks been waiting for? invitation?
Dude at the end i was no way this video is ending it has only just begun. Can't wait for pt.2
Holy Moly! Did Der8auer just take a dump on Thermal Grizzly? Dude's got balls.
His own company
Fantastic! I keep ordering based on this rating they slap on pastes and this has taught me a lot
I love the collaboration You have with all the other TH-camrs! It's always a treat to see you get together for a video!
yeah...we gonna need to see that whole convo bro. in advance Thanks Steve!
I want to thank you guys for the absolute work, knowledge, dedication, and integrity you put into your testing and reviews for all of us to enjoy and benefit of off. Best of the bunch right here on show~

Awesome video. Best one in a long time
Awesome discussion and very helpful for people coming into pc building new. Cheers.
Thanks Steve.
Love it when Roman do piece discussion with you, guys! Wish it was a more common thing! But, well, distance is a biatch!
Now, on about the testing:
On die application Pump-out effect is the biggest issue and the one that should be focused the most when testing pastes.
A lot of "high" end pastes perform between a few degrees of each other when applied on a IHS, but, when it comes to die application, few passes the test after some thermal cicles because of pump out effect.
Id love to see you guys do a huge round up on this subject with the most popular pastes.
I LIKE long form, in-depth, content. 50 minutes I've stood on street corners intensely conversing twice as long! A LOT of us like longform; my favourite English tech tuber used to regularly go 60 minutes + and I loved that; now thirty minutes is not a regular thing. Shorts? Go away! We WANT in depth and we want our content creators bouncing of one another! My favourite content has been when y'all invade one anothers content and we get something impromptu and when y'all decide that since we are here, lets do something longer and more specific together. I know we wrag you pair, but it is rather marvelous and very entertaining! Successful enthusiasts with serious cashflow and turnover! Hot damn; we are so lucky to have you! All the best and onwards and upwards, guys.
Der Achtauer ist ein richtiger Held! 😊 Love these vids by Gamer Ne10us, keep it up!
I would love to see more TIM benchmarks. *nudge nudge*
This talk just shows how much they are needed.
i love it too see you two guys work together..... RESPEKT to BOOTH !!!
love love love Der 8Auer, should only been shown in soft focus and slow motion
you guys are awesome doing a video together!
Thanks for that, that must be the reason why I've never really noticed any difference between different pastes. In the future I will put more weight into reviews when buying paste.
I feel like we should have a graph of thermal conductivity showing the results at say 5 or 10 degree intervals between idle temps and thermal throttling (maybe 115C for the top end) to give a reliable, relatable and comparable results table
If u guys made a podcast, i will listen to it all day
Love you guys! :D
The thumbnail for this video is hilarious! It looks like Steve is disgusted at the amount of thermal paste used and Der8auer is amused by it.
two legends of the scene. hell yes.
Ok. 1:22 during the 0Dark ad roll, the cooler is sitting on top of a cpu. Is that a k6 AMD chip? That’s pretty sweet. Throw back to my very first pc build Christmas 1998.
Still no update on the Mycro direct die waterblock sitting right in front of both of them...gotta love waiting for something that was mentioned nearly 2 months ago at this point.
I remember when I changed the alphacool Sub Zero thermal paste, that was very good and I had perfect temperatures, for the Alphacool Apex thermal paste, I had a great improvement because of the better thermal conductivity. Made the same (really I did here first) in the Gpu, where everything was a good, a perfect starting point, and I had 5, 6 degrees more of improvement. Thermal conductivity of thermal paste and thermal pads was more important of what I thought in a first time. Liquid metal I will try in the future. Great meeting!
Best tech TH-camrs together. Nice to see :)
awesome honest talk 👌👌👌
It's always good to have Broman onboard. And twice the ranting, oh my.
This is a great video and shows the real issue with current marketing and listed performance specs used by manufacturers and resellers.
Even within a manufacturer's product line, they are all over the place. Other times there are apparent manufacturers which are actually just resellers and rebrand products as their own, sometimes claiming a different w/mk rating than that actual manufacturer without using any more additives. I no longer trust w/mk ratings at all and rely on testing to tell the truth.
A good example of ratings not being accurate within a manufacturers product line would be T-Globals TG-PP10 thermal Putty (rated at 10w/mk) vs *TG-NSP80 (Rated at 8.3w/mk, *NOT SAFE for electronics as it conducts electricity). In this comparison the TG-PP10 conducts heat almost as well as Gelid GP Extreme pads, where as *TG-NSP80 would theoretically beat all currently available thermal pads (with the exception of 3D Graphite pads). Luckily we now have some extremely high performing Thermal Putties that don't conduct electricity and can effectively be used to replace Thermal pads on VRAM, VRM, etc.
For anyone interested in Thermal Putties I currently recommend Upsiren UX Pro as the best performing, although that may change as we discover/test more putties in the future.
The amount of physical mirroring with how y’all touch your hair and hold your arms is adorable
We need more 8auer and GN Tech Talks and Rants!
You are so nice guys!
The video title is clickbait for sure... I have never seen Der8auer ranting (in a video) - it would have been the first one.
Unfortunately, I can only like it once, would love to like it twice! Like-Like!
Thanks, Mr Steve.
This is so friggin awesome! Deep dive content like this with experts is awesome.
Fantastic video. Props to Roman for explaining the topic so well and being honest about it.
Thanks for the education on the conductivity numbers.
I always go for Artic MX, price-performance-endurance ... it strikes a good balance for me i'd say.
But ofc i like the ThermalGrizzly stuff, everything enthusiast is just cool.
Thanks Steve!
Great combo . 😌😌👏👏👍🏻👍🏻
I need a der8auer and Steve podcast.
I've used Arctic paste for years. Currently using MX-4, since I can get as much as I want by driving up the road 5 minutes to my local PC parts place. I am curious about the Thermal Grizzly Cryosheets.
Der8aur is such a cool dude, love his channel
Something something cooling this and that but wait... Stargate tattoo?? Awesome. But in all seriousness, love this content, looking forward to the rest of it!
I know this probably is very niche content, but this is good stuff. Thanks for sharing it with us.
Remember graphite thermal pads , pepperidge farm remembers . They were the talk back in the day about how long lasting they were and they somehow stopped being mentioned all together .
This was very cool, two very smart people.
Gotta say, I love Der8auer's sleeve, he's clearly a man of culture!
I would like to know what gate address that is??
@@Borg1701 th-cam.com/video/qCFQGfLCsKQ/w-d-xo.html He says its from the episode "Window of Opportunity"
@@Yoshi92 Thanks, I was curious as well. Great episode too!
My newest build is with the Der8auer Lian Li011 dynamic Evo. Perfectly happy with it would recommend it to everyone I know.
I never noticed that Der8auer has a Stargate tattoo, that's pretty cool
This fits right in line with IgorsLab recommendation for thick and very soft thermal pads but with low/medium thermal conductivity for GPUs!
On the Wireview you have there on the table, is that just bare metal connecting the raised connector to the PCB? Could you accidentally touch that when installed and get shocked?
50 minutes? Wow guys your endurance is legendary
I still have a Prolimatech PK-1 Thermal Compound. I once build a Pc for my aunt it was an AMD Athlon 4850e (Dual core). When I bought it, it was relatively new. So could have been mid 2009. Summer 2022 I took the Pc apart that was used till then. I demounted the cooler and the paste was still like day one. It was not dryed out, it was still thick and sticky. I could have remount the cooler directly back on and it would have worked flawlessly I'm sure. Really impressed with the longevity.
Just a little shutout to Prolimatech.
I don't know what I used as thermal compound when I put this PC together but I am really happy with it so far. I used the packet that came with the cooler. Either that or the temperature sensor is just busted in this thing. But my temps are always really good. I put this PC together years ago too. Right now the hottest core is +36.0°C the low one says it is +32.0°C so that's real good.
A very thorough test of thermal pasts would probably take a couple years and a super consistent way of applying it. Testing by applying to a system and doing a heat tests immediately and again some time down the road. The trick is making a lengthy lab test into content.
maybe in 10 years LTT labs will have finally started to do testing!
Just built my new machine, 7950X with an ASUS X670E-A (I know, I bought it before the current issues) and a RTX4090. I used hydronaut as my TIM but to be honest I don't think it would matter what I chose. That 7950X runs so bloody hot (at load) due to it's IHS, if I want it any cooler my only option would be a delid and direct die which I'm not 100% comfortable in doing.
Was an interesting build, 128GB of 6400 DDR5 that can NEVER run at 6400, the best I got was 4800 (5000 with occational boot failures.) I do like the 011D Dynamic XL case though. Just don't buy a shift version of a PSU though, you'll have to remove a drivebay, LOL. I was waiting for the new 011D Evo XL which now won't be out until October so got fed up waiting for it.
Any word on when cyrosheet gonna be available? Super excited about it.
So, it sounded like Roman was suggesting that Kryonaut doesn't have great longevity? As a user of it, should I be concerned / repaste more frequently?
Great to see Germans and Americas Hardware and OCs #1 👍
Roman is such a cool and honest guy. When he says it doesn't really make sense to buy the extreme paste...instant respect and trust! Great interview Steve.
anyone reading basic data knew this a long time ago. the fact someone waited til now to believe it because "he said so" is just friggin sad...
Had a chuckle to myself. If you didn't know the protagonists of this video, one would assume the ranting Derbauer was on the right in the thumbnail.
I used Liqui Moly silicone grease mixed with loads of graphite powder because I had issues with the noctua thermal paste and I needed my laptop to run on a saturday night
the DIY paste did better than noctua and lasts for a few years now while the noctua started seperating and was useless after 6 months
