WEBVTT 00:00:00.160 --> 00:00:06.160 everything about this computer is designed to do one thing beat the 00:00:03.840 --> 00:00:13.280 competition price for practicality be damned rtx 3090 ti 1200 motherboard 00:00:09.599 --> 00:00:16.160 graphene infused liquid coolants and the 00:00:13.280 --> 00:00:21.840 centerpiece of our so fast it's kind of stupid computer the Intel core i9 12900 00:00:19.359 --> 00:00:27.599 ks a product that as far as we can tell only exists so that Intel can still say 00:00:24.880 --> 00:00:31.679 no matter how many asterisks they have the fastest gaming CPU and what do you 00:00:29.760 --> 00:00:35.600 do with something like that well you don't really bother to review it because 00:00:33.920 --> 00:00:41.040 it's never going to make any sense instead you take things one step further 00:00:38.399 --> 00:00:47.520 by making it even dumber that's right we have obtained the rocket cool copper ihs 00:00:45.200 --> 00:00:51.760 for 12th gen this is a product that assumes you have so much disposable 00:00:49.600 --> 00:00:56.800 income you can not only buy the fastest thing just have the bragging rights but 00:00:53.760 --> 00:00:59.600 you can spend more risk destroying it 00:00:56.800 --> 00:01:05.840 and all just to drop your CPU temps by a few degrees well like 15 some people say 00:01:01.920 --> 00:01:08.159 15 degrees 15. holy crap well this is 00:01:05.840 --> 00:01:12.240 going to be fun then in it almost as fun as telling you about our sponsor build 00:01:10.000 --> 00:01:15.680 redux build redux offers competitive pricing as compared to building a pc 00:01:13.920 --> 00:01:18.960 yourself their website makes it easy for you to configure your build alongside 00:01:17.360 --> 00:01:23.360 their helpful support guides head to build redux dot com Linus and start 00:01:21.040 --> 00:01:26.720 building your pc right now rocket cools claims raise a lot of questions for me 00:01:25.200 --> 00:01:31.680 there's no doubt that copper's an excellent conductor of heat or that the 00:01:28.479 --> 00:01:33.520 12900 ks is a hot power hungry chip that 00:01:31.680 --> 00:01:38.479 could benefit from additional cooling but here's the issue 00:01:35.680 --> 00:01:42.159 integrated heat spreaders have been made of holy is this one not 00:01:40.400 --> 00:01:47.200 copper ah yes it is integrated heat spreaders 00:01:44.799 --> 00:01:50.640 have been made of copper basically going back 00:01:48.720 --> 00:01:55.600 as long as i've been an enthusiast i mean this is a pentium 4 from 2003. 00:01:53.600 --> 00:01:59.680 of course you might say but that copper has this other stuff on top of it 00:01:58.159 --> 00:02:03.040 but that's the thing that's not a problem that's nickel 00:02:01.200 --> 00:02:07.040 plating nickel plating performance coolers has been common practice for 00:02:04.719 --> 00:02:11.200 over 10 years and the layer is so thin that it's been well demonstrated that it 00:02:08.800 --> 00:02:14.319 doesn't have any impact on cooling according to rocket cool it comes down 00:02:12.720 --> 00:02:18.959 to their design which supposedly improves surface area by nine and a half 00:02:16.080 --> 00:02:24.879 percent as well as their quality they say that their ihs is extremely flat 00:02:22.160 --> 00:02:29.520 which we know should have a positive impact on our cooling but here's the 00:02:27.040 --> 00:02:34.160 thing alex i know that Intel is mass producing these things by literally the 00:02:32.000 --> 00:02:37.680 millions but is it conceivable that in that mass production they're allowing 00:02:35.599 --> 00:02:42.160 their tolerances to slip such that some random could make it more perfectly more 00:02:40.239 --> 00:02:46.480 accurately yeah i really doubt that Intel spends 33 dollars on their ihs i'm 00:02:44.800 --> 00:02:51.840 sure it's clear to everyone that neither of these are 33 worth of copper and both 00:02:49.519 --> 00:02:55.360 of them had to be cnc machined so what makes one of them 00:02:53.280 --> 00:02:59.680 more expensive to machine the tighter your tolerance is so the flatter it is 00:02:57.440 --> 00:03:03.440 the more expensive it gets why better machine more time both but then why 00:03:01.840 --> 00:03:06.640 wouldn't Intel just use a better machine at their scale well because they're 00:03:04.959 --> 00:03:10.080 doing so much scale they only have to make a couple of these guys Intel is 00:03:08.319 --> 00:03:13.440 making thousands and thousands of those that adds up fast so they want to go 00:03:11.920 --> 00:03:16.560 fast yeah they want to go fast could it make that much of a difference we can 00:03:15.040 --> 00:03:20.959 actually get some idea by taking a closer look at the thermal paste pattern 00:03:18.879 --> 00:03:24.159 of our stock ihs it looks like there's way more pressure right in the center 00:03:22.640 --> 00:03:29.040 which is good that's right where the dye is and then around that not so much so i 00:03:26.959 --> 00:03:33.840 imagine this part not doing a whole lot of cooling but enough talk now it's time 00:03:30.879 --> 00:03:38.080 to perform surgery on the 800 CPU that i just bought yesterday can you believe 00:03:36.080 --> 00:03:41.200 Intel wouldn't send us a second sample after the review what a bunch of jerks i 00:03:40.159 --> 00:03:46.080 know right ah there are a few different configurations that you can get your 00:03:43.920 --> 00:03:50.799 copper ihs upgrade kitten you can get just this and that's 33. or if you don't 00:03:48.959 --> 00:03:54.959 have any de-litting tools or anything like that you can get the full kit for 00:03:53.120 --> 00:03:59.840 80 us dollars which is everything you need to take apart and reassemble your 00:03:57.760 --> 00:04:03.519 CPU well there's no glue you need to buy the glue separate oh you just go buy 00:04:01.280 --> 00:04:07.760 silicone glue oh that's probably fine uh they recommend ca actually it seems like 00:04:05.760 --> 00:04:12.080 yeah i would think it'd be too brittle all right well we're gonna follow the 00:04:09.519 --> 00:04:12.080 instructions 00:04:12.879 --> 00:04:18.079 jeez sorry the d lidding tool is 00:04:16.160 --> 00:04:23.360 machined to delrin not as fancy as devourers and you actually have to 00:04:20.720 --> 00:04:27.520 insert your CPU and then screw it shut in order to 00:04:25.600 --> 00:04:31.199 operate it which is a little less user friendly but it's also significantly 00:04:29.600 --> 00:04:34.880 lower cost and they say the whole thing can be done in a few minutes and from 00:04:32.800 --> 00:04:39.840 the look of it i believe them wait why am i using this thing when i have an 00:04:36.240 --> 00:04:39.840 lttstore.com screwdriver 00:04:39.919 --> 00:04:46.400 the next stage of the instructions are pretty crap it just says set a two-minute timer with a heat gun no 00:04:44.639 --> 00:04:50.479 mention of temperatures or anything like that fortunately we're fairly smart we 00:04:48.560 --> 00:04:54.880 can figure out that we need to melt the solder that is attaching the original 00:04:52.720 --> 00:04:59.280 ihs to the die oh that's actually a benefit to the delrin it'll sap away 00:04:57.040 --> 00:05:03.680 less heat once we clamshell it up what are we at looks like we're right around 00:05:01.360 --> 00:05:08.080 130 degrees so that isn't hot enough to melt solder probably lead free around 00:05:05.720 --> 00:05:12.240 270 degrees but it is going to be getting softer for sure the delrin's at 00:05:10.000 --> 00:05:17.199 about 140 degrees right now so probably don't touch it we're gonna want to move 00:05:14.400 --> 00:05:23.120 reasonably quickly here this seems like a crap ton of pressure i feel like i'm 00:05:20.240 --> 00:05:26.240 ruining it i found on soldered cpus if it doesn't feel quite right when it 00:05:24.800 --> 00:05:30.000 starts moving in one direction like it doesn't pop off if you flip it and then 00:05:28.720 --> 00:05:34.560 push it the other way you can kind of just strain fatigue well it's moving 00:05:32.080 --> 00:05:39.680 freely now so that's cool look at that beautiful and not even that 00:05:37.199 --> 00:05:41.759 burny the next step is to scrape it then right 00:05:40.560 --> 00:05:46.320 what are you scraping i'm going to scrape the solder okay well first we need to get rid of the black crap just 00:05:45.199 --> 00:05:51.120 one step at a time i told you they include a scraping tool and i can't believe that we bought this 00:05:50.080 --> 00:05:56.880 yesterday and we are already doing this to it 00:05:53.360 --> 00:05:58.400 this is an abuse we're making faster 00:05:56.880 --> 00:06:02.560 scraping tool just feels like just the right hardness 00:06:01.120 --> 00:06:06.960 sorry how exactly does this tape gun work the blade is recessed i just push 00:06:04.800 --> 00:06:10.319 the thing when you have a box you know it goes over you push it it comes out oh 00:06:08.880 --> 00:06:15.440 that's actually quite clever which is good because i think i paid a lot for this thing like 00:06:13.199 --> 00:06:18.800 way back in the day it's taped down now what oh this is the cool part i really 00:06:17.199 --> 00:06:22.800 like how they've done this instead of you know sometimes you have to use like 00:06:20.560 --> 00:06:26.800 a razor to get the solder off and it's just terrible here you just use 00:06:24.319 --> 00:06:32.319 chemicals i believe this is indium and it eats away the solder so you just 00:06:28.639 --> 00:06:35.039 apply it shut up spread it around and 00:06:32.319 --> 00:06:38.639 it gets rid of it okay that's pretty neat 00:06:37.280 --> 00:06:43.199 no you don't want to get don't want to get that in your eyes but the other way 00:06:40.479 --> 00:06:48.960 to do this apparently is mercury and that's a lot worse that's true and 00:06:46.479 --> 00:06:52.780 one two three four gotta say the little tissues i dispose 00:06:50.880 --> 00:06:54.160 of usually don't look like this 00:06:54.160 --> 00:07:00.560 the next bit is you just wanna give it a little polish okay a little dab of this 00:06:58.560 --> 00:07:05.199 on some paper towel oh i thought this said flitz polish like from poland 00:07:05.520 --> 00:07:11.680 oh yeah if you kind of look at how they did it here um 00:07:09.520 --> 00:07:14.000 they just do a little bit of the corner uh-huh yeah 00:07:13.120 --> 00:07:18.560 yeah don't mind me i'm just polishing my CPU 00:07:16.319 --> 00:07:18.560 here 00:07:20.400 --> 00:07:23.440 that's that's probably good 00:07:25.759 --> 00:07:31.919 hi brandon how you doing i am really glad that i did an accurate job of that 00:07:29.680 --> 00:07:36.000 taping because that ended up being quite messy to be clear i don't think the 00:07:33.919 --> 00:07:38.400 process has to be that messy that's what she said 00:07:39.120 --> 00:07:44.960 look at that it's gorgeous 00:07:42.639 --> 00:07:49.039 oh balls oh it's everywhere oh it's all over my hands i guess this is a 00:07:46.479 --> 00:07:51.759 situation where having a delrin thing would be good 00:07:50.400 --> 00:07:56.960 that would be eating into aluminum right now okay i'm just getting more liquid metal on this by touching it because my 00:07:54.960 --> 00:08:01.919 hands are covered in liquid metal at any rate there's a 12th gen thing here okay 00:07:59.520 --> 00:08:07.360 go ahead we put our CPU in whoop we're gonna put this here oh god 00:08:04.000 --> 00:08:09.280 oh god jesus christ okay 00:08:07.360 --> 00:08:13.039 uh where'd our liquid metal go oh here it is 00:08:10.960 --> 00:08:16.080 whoa no that's too much oh stop stop stop stop come back 00:08:17.280 --> 00:08:22.479 i might have put on too much alex no that seems good unlike applying thermal 00:08:20.800 --> 00:08:27.440 compound to your heat spreader here it's important to have complete coverage of 00:08:24.720 --> 00:08:32.479 the dye because every part of it has the potential to get extremely hot and any 00:08:31.120 --> 00:08:38.159 part of it that doesn't have thermal compound coverage is a disaster oh man 00:08:35.440 --> 00:08:42.719 this is what a what a ride i feel like we've waited so long to unbox this now 00:08:40.800 --> 00:08:45.680 look at that you can actually see the tooling marks on the top it's kind of 00:08:44.320 --> 00:08:49.200 hard to catch but they kind of go this way that's not 00:08:47.600 --> 00:08:53.600 necessarily a bad thing that doesn't mean that it's not flat it just means 00:08:51.600 --> 00:08:57.440 that you can see the marks a little bit oh i see so it is a little bit bigger 00:08:55.440 --> 00:09:02.080 yeah i see that wow alex i see what you mean like this yellow rectangle isn't even 00:09:00.640 --> 00:09:06.080 it's like they didn't even try to center it why rocket cool includes a nice 00:09:04.480 --> 00:09:10.560 little guide here to show you where to apply just a little bit of liquid metal 00:09:08.480 --> 00:09:15.760 to the underside of the ihs not gonna lie this looks sick 00:09:13.360 --> 00:09:20.839 okay wait we didn't put glue on oh my god that is a giant thing of ca uh how 00:09:18.240 --> 00:09:24.720 are we applying this i have an idea ready 00:09:22.800 --> 00:09:27.360 for rca i'm just going to make a puddle of ca 00:09:28.959 --> 00:09:33.120 we go ahead and just drop it into place 00:09:33.519 --> 00:09:39.920 and here we go does this feel like absolute madness or what i don't know 00:09:38.160 --> 00:09:46.399 this seems fine like Intel making the cpus the madness in fairness it does 00:09:42.959 --> 00:09:49.040 what is it 5.5 on two cores two course 00:09:46.399 --> 00:09:54.880 it's fast it's really fast in my testing that i did it was doing 5.2 all core all 00:09:51.760 --> 00:09:58.160 day pretty great okay um oh did you see 00:09:54.880 --> 00:09:58.160 it glued to the thing no 00:09:59.279 --> 00:10:06.240 oh there it goes what's uh liquid metal 00:10:04.560 --> 00:10:12.240 why don't you handle the CPU from now on okay fun fact alcohol not only dries 00:10:08.800 --> 00:10:13.680 quickly but it's a drying agent 00:10:12.240 --> 00:10:16.399 don't do that you want to get all sandpaper wank later that's how you do 00:10:15.760 --> 00:10:20.560 it okay that's pretty cool and the cooler 00:10:18.800 --> 00:10:25.760 we're gonna put on it is about as good as it gets until you get into peltier or 00:10:23.360 --> 00:10:29.600 phase change cooling it's a fully custom loop with ample radiator space for this 00:10:27.760 --> 00:10:32.800 heat and that bit about graphene-infused coolant we did a whole video about it it 00:10:31.279 --> 00:10:38.800 actually does drop the temps a couple of degrees so this is as good as it gets 00:10:36.560 --> 00:10:41.440 man this is way more extreme than just buying the highest end parts and 00:10:40.079 --> 00:10:47.040 throwing them together we are trying to shave every degree off of this CPU 00:10:44.480 --> 00:10:49.680 moment of truth hey there we go 00:10:49.920 --> 00:10:56.720 do you believe this will have worked 15 degrees is a bold claim for 33 00:10:54.800 --> 00:11:01.120 i mean you could spend 33 more dollars on a cooler and it wouldn't drop your 00:10:58.160 --> 00:11:04.160 CPU temps 15 degrees well this cooler will do that anyway i think it'll be 00:11:02.560 --> 00:11:08.079 around 10. i've seen a lot of people comment that it's like a 10 degree drop 00:11:05.920 --> 00:11:12.640 which is really crazy that's also really impressive and it booted which is good i 00:11:10.399 --> 00:11:16.959 managed to not kill it really alex Windows 11. you know the 00:11:14.399 --> 00:11:21.920 people are gonna be mad right prime95 yep small small fft blend 00:11:20.079 --> 00:11:27.200 wait this thing hit 100 degrees in a blend test after like nine minutes or 00:11:24.160 --> 00:11:29.760 something yeah really yeah on custom 00:11:27.200 --> 00:11:34.320 water cooling well it's like 240 watts sustained out of the box yeah wow 00:11:32.000 --> 00:11:38.240 actually two of the cores are at 5.5 yes like they said now before we actually 00:11:36.640 --> 00:11:41.440 put the processor under load is a perfect time to have a look at all of 00:11:40.000 --> 00:11:46.240 our temperature sensors and make sure that none of them are a huge outlier 00:11:44.320 --> 00:11:49.279 which could indicate that we didn't have adequate coverage of our liquid metal 00:11:47.839 --> 00:11:52.720 and it looks like this is all in 00:11:50.880 --> 00:11:56.480 okay shape and we're ready to press go i mean we're going to know almost 00:11:54.000 --> 00:12:00.320 immediately if this worked wow now to be clear it did take 00:11:58.640 --> 00:12:04.560 eight minutes for it to thermal throttle last time but i don't think we're gonna 00:12:02.399 --> 00:12:09.120 get that yeah we haven't hit 60 yet this is interesting for a couple of reasons 00:12:06.959 --> 00:12:13.519 first we can see why it's best not to use prime95 blend for a stress test 00:12:11.760 --> 00:12:19.760 that's okay but as long as we do it both times that's kind of flipping incredible 00:12:16.959 --> 00:12:23.120 it's not 15 degrees incredible but it's a lot better than a kick in the 00:12:21.600 --> 00:12:29.440 teeth it's in the neighborhood just shy of 10. 9 degrees while consuming 20 more 00:12:26.320 --> 00:12:31.519 watts is really impressive remember that 00:12:29.440 --> 00:12:36.079 extra power consumption means that our cores are boosting higher and for longer 00:12:34.480 --> 00:12:39.680 this is great right yeah i mean i'm pretty stoked do 00:12:38.320 --> 00:12:44.720 you know what's even more impressive when we went for lunch we forgot to stop 00:12:41.519 --> 00:12:48.000 it yeah it's still fine under 90. it's 00:12:44.720 --> 00:12:49.519 been running for an hour now and before 00:12:48.000 --> 00:12:54.959 after like 10 minutes it was thermal throttling now it's what 85 degrees it's 00:12:51.920 --> 00:12:56.639 amazing yeah 90 on the hottest peak 00:12:54.959 --> 00:13:01.440 i can really feel the heat coming off it though oh yeah it doesn't feel like 00:12:58.880 --> 00:13:06.959 that's just a CPU worth of heat but i mean that's what holy sh 300 watts 00:13:05.600 --> 00:13:10.480 yeah that's crazy 00:13:08.720 --> 00:13:15.839 how can you have a CPU pulling through ow the freaking vrm heatsink because 00:13:13.600 --> 00:13:19.200 where's my thermal camera oh yeah i guess there's no fans pointed at that 00:13:17.279 --> 00:13:24.079 because it's a test bed yeah well i didn't think it was gonna be pushing 300 00:13:21.600 --> 00:13:28.800 flipping watts those poor vrms are putting like 250 amps through them right 00:13:26.399 --> 00:13:32.639 now the pcb is at 72 degrees 00:13:31.360 --> 00:13:37.839 what what are you oh network switch 00:13:35.200 --> 00:13:41.360 ups a power brick i need to take this thing home and just like play with it 00:13:39.120 --> 00:13:44.639 with my kids this thing is so cool all right do you want to run a couple 00:13:42.240 --> 00:13:48.800 more tests i'd love to bmw is a pretty short blender render though hey yeah but 00:13:46.399 --> 00:13:53.760 it allows us to see if it runs faster in like thermal velocity boost range 00:13:50.959 --> 00:13:59.120 right so uh one minute 28 to beat and the maximum temp was 95 degrees it's 00:13:56.720 --> 00:14:02.639 really fast yeah it's really fast so that is about 10 degrees better oh 00:14:01.120 --> 00:14:07.839 yeah i guess that's a good point brandon that that actually is 10 degrees better 00:14:05.440 --> 00:14:13.440 as advertised here it is 75 versus 82 degrees okay only 8 degrees 00:14:12.399 --> 00:14:17.440 but that's that higher power draw so wait if 00:14:16.000 --> 00:14:21.920 it's higher power draw was the result even any different though it was one 00:14:19.279 --> 00:14:25.440 second better one second faster but then by the time you're spending 800 00:14:23.920 --> 00:14:30.959 on your CPU you're probably spending a total of around three grand 3500 on the 00:14:29.120 --> 00:14:35.760 whole machine what's another 40 bucks for one second better and you could 00:14:33.519 --> 00:14:41.199 overclock it now like there's enough headroom that if we won do we go for 5.6 00:14:38.800 --> 00:14:47.360 i just went on do we have xtu on here yeah of course we do xtu shows us just 00:14:44.320 --> 00:14:49.760 how good this CPU has been i have the 00:14:47.360 --> 00:14:54.959 same profile that's pretty much exactly the same clocks as this was stock and 00:14:52.000 --> 00:15:01.120 that was pulling about 350 400 watts should i just push everything up 100 00:14:56.959 --> 00:15:01.120 megahertz and see what happens yeah 00:15:01.760 --> 00:15:08.639 current limited so we're gonna need to up our voltage of it do 0.1 that's 00:15:05.839 --> 00:15:14.320 pretty safe it's amazing how close to the sun Intel is flying with this thing 00:15:11.440 --> 00:15:17.920 i just want to see if it actually hits that frequency 00:15:16.160 --> 00:15:24.079 no it's slower okay definitely going to take some 00:15:21.760 --> 00:15:27.920 fine tuning to get this thing to run any faster than stock but it's cooler all 00:15:26.240 --> 00:15:32.800 right you want to do a game test yeah for our tests i chose shadow of the 00:15:30.399 --> 00:15:36.959 tomb raider and forza just because they give you what the CPU is outputting 00:15:34.959 --> 00:15:44.320 because the CPU is so fast that everything's GPU bound pretty much that 00:15:39.199 --> 00:15:44.320 is some killer coil wine on this 3090 ti 00:15:44.880 --> 00:15:51.040 i mean that's what happens when we have 450 watt or it's rumored they could be 00:15:48.639 --> 00:15:54.959 even higher for the next gen gpus this computer legitimately if you have like 00:15:52.959 --> 00:15:58.160 bad not up to code wiring in your house it might burn down but look at these 00:15:56.639 --> 00:16:02.320 reflections 110 FPS 00:15:59.920 --> 00:16:07.360 that's exactly the same as before but it's GPU bound we actually got five more 00:16:04.240 --> 00:16:10.399 FPS on the CPU it's a win if we had a 00:16:07.360 --> 00:16:11.279 faster GPU we'd get five more FPS yeah 00:16:10.399 --> 00:16:17.759 and a 378. uh we'll worry about CPU game and 237. 00:16:16.880 --> 00:16:24.320 that's 7fps higher and the average FPS is exactly the same 00:16:21.920 --> 00:16:31.199 again so there you have it if you want every last little bit of performance 00:16:27.680 --> 00:16:33.600 you can buy one of these or if you want 00:16:31.199 --> 00:16:37.839 almost as
