WEBVTT 00:00:04.319 --> 00:00:10.880 i played about a total of 20 minutes of minecraft in my life and i gave up every 00:00:08.480 --> 00:00:15.759 time because i had no idea what the heck i was even supposed to do so when Jake 00:00:14.160 --> 00:00:20.080 stormed into my office and asked to spend work hours building an official 00:00:18.000 --> 00:00:24.800 LTT minecraft server my answer was fairly concise 00:00:22.320 --> 00:00:29.439 no of course Jake being Jake he went ahead and did it unofficially on his own 00:00:27.199 --> 00:00:34.719 time then came back into my office saying look how cool this is by the way 00:00:32.480 --> 00:00:38.719 now that it's all cool you can have it if you compensate me for those hours 00:00:37.520 --> 00:00:43.280 and he's right it is pretty cool so 00:00:41.840 --> 00:00:48.000 here we go if we're gonna make a minecraft server it better be the best 00:00:46.000 --> 00:00:55.280 server that money can buy so with the help of protocase we're going to design 00:00:51.200 --> 00:00:58.559 fabricate and then deploy the ultimate 00:00:55.280 --> 00:00:59.480 minecraft server build with not one but 00:00:58.559 --> 00:01:06.080 two 9900k processors inside a single 2u 00:01:03.359 --> 00:01:09.760 chassis with a whole heck of a lot of water cooling today's video is brought 00:01:08.159 --> 00:01:13.520 to you by rozzy stay cool and comfortable for hours with rossi's new 00:01:11.840 --> 00:01:18.170 breathable furniture fabric edition chair use code Linus tech rozzy.com to 00:01:16.000 --> 00:01:23.139 get 10 off 00:01:26.080 --> 00:01:33.840 so our use case here is obviously very specific we want to be able to run as 00:01:30.880 --> 00:01:38.960 many ball in minecraft server instances as we possibly can and because minecraft 00:01:36.640 --> 00:01:43.280 java edition is so dependent on single threaded performance 00:01:40.400 --> 00:01:48.320 this is one of those special cases where running xeon or epic in a server would 00:01:46.320 --> 00:01:52.640 result in a much worse experience for the users than frankensteining together 00:01:50.560 --> 00:01:57.040 some desktop hardware so then given we were after the highest single threaded 00:01:54.479 --> 00:02:01.360 performance possible and Intel hadn't launched the 9900ks yet we hooked up 00:01:59.600 --> 00:02:06.320 with the guys over at silicon lottery who were able to provide us with a 00:02:02.799 --> 00:02:08.080 discount on a core i9 9900k CPU that's 00:02:06.320 --> 00:02:14.239 been pre-validated to run at five gigahertz on all cores so basically it's 00:02:11.120 --> 00:02:16.800 a 9900 ks then for our second system we 00:02:14.239 --> 00:02:21.920 stole the bin's 9900k from gigabytes waterforce kit which means we should be 00:02:19.360 --> 00:02:28.000 able to have eight separate minecraft server instances all with their own 00:02:24.400 --> 00:02:30.000 overclocked 9900k core per CPU for a 00:02:28.000 --> 00:02:34.640 total of 16. not too shabby 00:02:32.400 --> 00:02:38.959 but wait a second Linus you can't run dual cpus on consumer hardware well you 00:02:37.440 --> 00:02:44.000 can if you run two motherboards so our clever idea was 00:02:41.360 --> 00:02:48.959 to grab a pair of overclocking capable mini itx motherboards and then cram them 00:02:46.959 --> 00:02:54.319 into a single case we settled on the ASUS strix z390i now this kind of a 00:02:52.319 --> 00:02:58.000 deployment could have negatively impacted the amount of RAM we could 00:02:56.160 --> 00:03:02.239 install but thanks to some recent developments in memory technology we can 00:03:00.000 --> 00:03:07.920 actually equip each of our boards with these double density dimms allowing us 00:03:04.640 --> 00:03:10.720 to fit 64 gigs of RAM onto each of our 00:03:07.920 --> 00:03:15.280 itx systems so java minecraft servers want about four gigs of RAM per instance 00:03:13.280 --> 00:03:19.360 which means that we can run a handful of those with extra RAM left over if we 00:03:17.599 --> 00:03:23.599 want to run a couple of our instances in a non-standard configuration with large 00:03:21.760 --> 00:03:27.920 mod packs which would need to be stored in system memory now if you're running a 00:03:25.840 --> 00:03:33.120 simple minecraft server for you and your frames storage size probably isn't going 00:03:30.159 --> 00:03:38.560 to be a huge concern but on our system we're going with dual 1 terabyte m.2 00:03:36.000 --> 00:03:43.280 NVMe ssds in a software raid 1 configuration for each board this allows 00:03:41.360 --> 00:03:47.440 us to load many different game modes onto our systems and allows us to use 00:03:45.519 --> 00:03:51.360 moderation and management tools like core protect which logs every single 00:03:49.920 --> 00:03:55.920 interaction that takes place on the server so modification to a block uh 00:03:54.400 --> 00:04:01.040 adding or removing something from an inventory etc etc so griefers can be 00:03:58.560 --> 00:04:04.879 dealt with more easily as a badge each interaction is 00:04:02.799 --> 00:04:08.720 pretty small in terms of storage size but it adds up pretty quickly if you've 00:04:06.720 --> 00:04:13.760 got hundreds of players and weeks of logs now because a standard atx power 00:04:11.360 --> 00:04:18.479 supply unit won't fit in our 2u thickness target we opted for an 800 00:04:16.079 --> 00:04:21.680 watt sfxl unit from silverstone that should still give us a ton of headroom 00:04:20.400 --> 00:04:25.919 even though it's going to be powering both systems through this fancy fantax 00:04:24.400 --> 00:04:30.080 power splitter that they don't sell anymore for whatever reason probably 00:04:28.160 --> 00:04:35.680 because no one wants to do that right uh by the way thanks person from twitter 00:04:32.320 --> 00:04:38.080 for sending that to us you rock so then 00:04:35.680 --> 00:04:41.280 that's a lot of hardware to cram into something this thick 00:04:40.400 --> 00:04:46.000 so rather than yoloing it um we started by 00:04:44.080 --> 00:04:50.160 laying out the components first in autodesk autocad to get an idea of how 00:04:48.479 --> 00:04:54.080 long our chassis was going to end up needing to be with all the cooling that 00:04:52.160 --> 00:04:59.600 we wanted to cram into it the original plan was to run regular 360 millimeter 00:04:57.280 --> 00:05:04.160 pc radiators like in our water cooled transcode server but since we did that 00:05:01.840 --> 00:05:08.560 project alphacool has actually started making 80 millimeter radiators 00:05:06.160 --> 00:05:12.400 specifically designed for use in 2u servers they even have mounting holes on 00:05:10.720 --> 00:05:17.199 the sides of the radiators so you can just screw them in from underneath the 00:05:13.840 --> 00:05:18.960 chassis these things are freaking sweet 00:05:17.199 --> 00:05:23.199 with the layout complete Jake started on the 3d design we took some cues from 00:05:20.960 --> 00:05:26.639 backblaze's storage pod servers but scaled them down to meet our 2u 00:05:24.800 --> 00:05:30.800 requirement this means most of the chassis is composed of one large sheet 00:05:28.960 --> 00:05:34.479 for the bottom and sides with screw and modular panels for the front back and 00:05:33.120 --> 00:05:39.120 top of the case we then added some flare to the front 00:05:36.320 --> 00:05:42.720 with LTT logo fan grills lots of holes for our radiators and then a big old 00:05:41.120 --> 00:05:47.199 cutout up front so that we could mount a five and a quarter inch bay reservoir it 00:05:45.120 --> 00:05:51.199 happens to fit in our 2u form factor absolutely perfectly and allows us to 00:05:49.680 --> 00:05:56.800 easily monitor our coolant levels without pulling the system out of the rack because of the standardized 19-inch 00:05:54.800 --> 00:06:00.560 rack mount width we couldn't fit our power supply in the back of the case if 00:05:58.720 --> 00:06:04.400 we also wanted access to both of our motherboards i o so we took some 00:06:02.320 --> 00:06:08.880 inspiration from modern small form factor pc designs and opted to 00:06:06.639 --> 00:06:12.080 internally mount the power supply and then plug it in with a cable 00:06:10.400 --> 00:06:16.080 pass-through that we got whipped up by infinite cables after that Jake added 00:06:14.319 --> 00:06:19.919 some small chassis support bars in the middle of the case to keep it rigid made 00:06:18.000 --> 00:06:24.479 a huge cutout in the top panel for some acrylic then we sent over the designs to 00:06:22.240 --> 00:06:28.560 protocase so this type of a one-off chassis is the perfect thing to have 00:06:26.479 --> 00:06:32.720 fabbed up by a company like protocase their no minimum quantity policy and two 00:06:30.960 --> 00:06:36.720 to three day lead time for most projects is practically unmatched in the industry 00:06:34.880 --> 00:06:40.400 and that's made them the choice for more than 14 000 engineers and makers from 00:06:38.880 --> 00:06:45.600 around the world including at companies like nasa boeing google mit and more now 00:06:43.440 --> 00:06:49.120 they did want us to mention however that the cost of a one-off case like this 00:06:47.520 --> 00:06:52.960 would be anywhere from fifteen hundred to two thousand dollars meaning it 00:06:51.440 --> 00:06:58.960 wouldn't be practical for the average home gamer but for our purposes this was 00:06:56.000 --> 00:07:04.639 absolutely perfect so now it's just time to show you the process of throwing the 00:07:01.520 --> 00:07:07.039 pieces together for our dry fit before 00:07:04.639 --> 00:07:12.000 we get started on the finished build so i guess it starts with the unboxing 00:07:09.919 --> 00:07:15.440 and bubble wrap what is this 00:07:13.280 --> 00:07:18.560 acrylic that's like the top panel okay cool or part of it anyways 00:07:18.800 --> 00:07:24.479 oh my god if that cracked it would be very bad 00:07:22.960 --> 00:07:29.599 it's not gonna crack you just want the world to burn hey oh stop 00:07:27.440 --> 00:07:32.720 ah it doesn't make a cool noise that'd make 00:07:31.199 --> 00:07:37.120 a cool noise oh some assembly required for our 00:07:35.120 --> 00:07:43.039 chassis here normally they will assemble it for you but some of these bits were 00:07:39.039 --> 00:07:44.240 easier and safer to ship separately so 00:07:43.039 --> 00:07:46.479 i don't actually oh that's the power to play 00:07:46.880 --> 00:07:52.240 ah what was that i fixed the kit 00:07:50.479 --> 00:07:56.720 hopefully ifixit isn't sponsoring this episode 00:07:54.000 --> 00:08:01.280 oh check this out guys i spent far too much time on that that 00:07:59.440 --> 00:08:06.240 is our fan grill check it out LTT logos all up in this 00:08:04.479 --> 00:08:11.080 biz it's gonna look so great when there's just like beige and brown behind 00:08:07.919 --> 00:08:11.080 it too 00:08:12.240 --> 00:08:17.360 popping it oh this is sick 00:08:15.919 --> 00:08:23.440 i know thank you all right so here it is guys 00:08:20.800 --> 00:08:27.520 this is the back of our chassis where our two motherboards go as well as 00:08:25.759 --> 00:08:31.280 our power pass through they're a little bit offset you'll notice and that's so 00:08:29.039 --> 00:08:34.000 the motherboards actually sit centered relative to each other in the chassis 00:08:32.959 --> 00:08:40.240 ooh but did we forget to put rail mounts on it uh 00:08:38.159 --> 00:08:43.839 it would appear so we can just tap those right we could also just like let it 00:08:41.680 --> 00:08:47.839 rest on something else then over here is the business end so 00:08:45.920 --> 00:08:50.100 this is where our five and a quarter inch bay res 00:08:49.279 --> 00:08:56.720 and on the outside yep oh is that going to 00:08:54.959 --> 00:08:59.839 increase the probe i don't think it does it must go on the inside i designed it 00:08:58.399 --> 00:09:04.320 it definitely goes on the outside i don't believe it thank you very much protocase fixed your bad design because 00:09:02.959 --> 00:09:09.440 if it's on the outside it wouldn't slide into a room oh i mean like on the outside like it goes in from this side 00:09:07.120 --> 00:09:13.120 no it doesn't go on no no yeah i see i see where the miscommunication is now it 00:09:11.360 --> 00:09:17.200 like it comes in from the outside yeah yeah okay that's fine you can't put it 00:09:15.040 --> 00:09:21.120 from the inside you're drunk Jake no it's not how it works 00:09:19.040 --> 00:09:24.800 the top is freaking awesome so as you can see it's going to be basically all 00:09:23.040 --> 00:09:28.320 acrylic tops so we can see all of our water cooling components in there oh wow 00:09:27.200 --> 00:09:32.240 what the hell that is some strong plastic on that 00:09:30.560 --> 00:09:35.680 little thing yeah i had to use a knife to get it off ow 00:09:34.320 --> 00:09:39.440 oh my god what did you just do just almost got myself in the eye oh should 00:09:37.760 --> 00:09:43.360 we just use the vibration dampers look at this oh yeah 00:09:43.680 --> 00:09:49.680 this is gonna be real tight Jake wow those look terrible yeah it doesn't 00:09:47.680 --> 00:09:54.480 really just use the screws okay fine forget it 00:09:51.680 --> 00:09:58.320 oh god these this plastic is like oh 00:09:56.080 --> 00:10:02.560 it's like kevlar reinforced plastics what the hell 00:09:59.600 --> 00:10:06.160 i am really into these they fit in a 2u and they're like really designed for it 00:10:04.640 --> 00:10:09.920 like these recessed fittings allow you to sandwich fans in between them if you 00:10:08.000 --> 00:10:14.560 want these side fittings and these rear fitting holes 00:10:11.920 --> 00:10:18.000 allow you to have any flow configuration that you want 00:10:15.920 --> 00:10:21.760 it's got mounting holes on the bottom super cool 00:10:19.839 --> 00:10:27.440 copper's expensive dude oh boy 00:10:23.200 --> 00:10:27.440 sweet sometimes things just work 00:10:28.720 --> 00:10:34.720 so we're not going to plumb it up today but in order to do a decent test fit we 00:10:32.320 --> 00:10:39.040 do at least need to mount our radiators and put the fans on them we've designed 00:10:36.720 --> 00:10:43.120 our rads to screw in from the bottom and then go together so tightly so we're 00:10:41.440 --> 00:10:47.680 gonna have what is it three of them three yeah so Jake's working on the last 00:10:44.880 --> 00:10:52.959 one right there it's gonna be sick you pop these together there we go 00:10:50.640 --> 00:10:56.560 how much radiator is that my friends why are you taking out that one it goes here 00:10:55.120 --> 00:11:00.480 i'm taking one off i might as well take them both off now would be a really bad 00:10:58.320 --> 00:11:05.600 time for these screws to not line up oh oh what it has to go in the other way 00:11:03.120 --> 00:11:09.200 oh god really yeah no it's right what are you talking about 00:11:07.279 --> 00:11:12.880 oh wait it's flipped on the other side what the crap yeah it's fine no i 00:11:11.040 --> 00:11:17.360 thought about this very extensively when i was doing this because i really didn't want to hold it up 00:11:15.680 --> 00:11:21.040 whoa these are going in no problems perfect 00:11:18.959 --> 00:11:24.959 everything lines up great huh it's always nice when things work out hey i'm 00:11:22.800 --> 00:11:27.920 gonna give myself a cookie for that oh wow 00:11:26.240 --> 00:11:33.600 how sure are you that that acrylic is going on here with these cables oh 00:11:31.120 --> 00:11:38.000 not very that's pretty tight like we were thinking maybe we could 00:11:35.200 --> 00:11:41.680 put it here or something but um i don't think so so then we came up with 00:11:39.839 --> 00:11:45.680 the idea so our reservoir fits 00:11:44.000 --> 00:11:49.440 perfectly these ports over here these are for like 00:11:48.320 --> 00:11:53.920 lights fill drain and then this is the inlet 00:11:51.600 --> 00:11:58.360 and that's the outlet it uses a d5 pump i don't think it's technically a d5 is 00:11:55.519 --> 00:12:03.200 it not technically a d5 no vpp 655t it's based on the same it's a d5 00:12:01.440 --> 00:12:07.279 but yeah it has variable speed control on there nice so it's a d5 vario yeah so 00:12:05.600 --> 00:12:11.200 our outlet is going to come out here go into our radiators and our inlet is 00:12:09.680 --> 00:12:15.279 going to come probably all the way from the front up the side 00:12:13.680 --> 00:12:20.160 that's going to be a long yeah sorry the back that is going to be a long tubing 00:12:18.000 --> 00:12:25.360 run oh no they're too loose oh it's these 00:12:23.680 --> 00:12:28.800 stupid that's actually a problem we will just 00:12:27.200 --> 00:12:32.079 not put in the i o shield and we'll just thread them in not quite all the way 00:12:30.480 --> 00:12:36.160 you know what actually take hold on a second with them not quite screwed in 00:12:34.079 --> 00:12:41.120 all the way it lines up perfectly so we can just put some loctite glue in these 00:12:38.959 --> 00:12:44.320 well it's a bit high not barely look at it well look at this side this side's 00:12:42.959 --> 00:12:47.760 not high yeah but there's a clip you see this like that 00:12:46.079 --> 00:12:50.639 exposed metal is like that on that side too it's as close as anything in this 00:12:49.600 --> 00:12:55.200 project wow wow so normally you would install 00:12:52.959 --> 00:12:59.680 your m.2 SSD under the spreader and put it back on but it has this gigantic 00:12:57.600 --> 00:13:03.200 heatsink on it so we're going to go ahead and just 00:13:00.800 --> 00:13:06.399 install it and leave it like that wait 00:13:04.399 --> 00:13:10.320 we have a problem Jake all right how do we install the second SSD that's on the 00:13:08.560 --> 00:13:13.760 bottom right but we have the crazy space so it's fine we have a crazy space this 00:13:12.399 --> 00:13:19.680 much space so we've got the bottom one installed there 00:13:16.639 --> 00:13:21.680 there's our dual ssds af 00:13:19.680 --> 00:13:25.680 now obviously we're aware that this cooler is not going to fit in our case 00:13:23.839 --> 00:13:29.040 might stick out the top a little bit you know but again this is just test fitting 00:13:27.680 --> 00:13:33.120 we are going to move to water cooling for the finished build um where's our 00:13:30.959 --> 00:13:38.399 power supply go um it's gonna go right here 00:13:35.040 --> 00:13:40.560 facing the wall here it is sfxl 800 00:13:38.399 --> 00:13:43.760 watts 120 millimeter fan do you see that it's not really 00:13:41.680 --> 00:13:48.000 necessary but this server is going to be shockingly quiet so that's going to go 00:13:46.160 --> 00:13:51.839 kind of like what their-ish okay so yeah that can go there this will go in 00:13:49.839 --> 00:13:54.880 between the boards right about yeah this is plenty long 00:13:53.120 --> 00:14:00.720 make sure the total power consumption of your two motherboards is not higher than 00:13:57.199 --> 00:14:04.079 452 watts of your motherboard oh boy 00:14:00.720 --> 00:14:05.839 screw it wow this thing is pretty crusty 00:14:04.079 --> 00:14:09.760 hey guy on twitter sent it to us it was sitting in his closet for like a year so 00:14:07.680 --> 00:14:13.519 it sure was oh yeah i guess we could do that 00:14:10.800 --> 00:14:16.639 just give it the ol wiper yeah 00:14:15.279 --> 00:14:20.480 should be fine it might not be pretty but it'll work all right 00:14:18.399 --> 00:14:23.120 there now for real it's done uh we can't slide the server onto the table because 00:14:21.920 --> 00:14:27.839 we haven't shaved the bottom of those standoffs yet oh we could just seat it um i don't want 00:14:26.639 --> 00:14:34.399 to scratch the tape this table's so banged up already you can barely they stick out like this far really 00:14:31.920 --> 00:14:39.839 we would be gouging that table put it out with the water from here oh 00:14:36.240 --> 00:14:41.600 my god there goes the bay reservoir 00:14:39.839 --> 00:14:46.240 it's great because you almost did it before and then actually did it now is 00:14:44.240 --> 00:14:50.320 it cracked why didn't we move that you know what it's fine no it's fine don't 00:14:48.560 --> 00:14:53.839 get it what if it's not it's fine it's sealed it's fine are you sure yeah it's 00:14:52.959 --> 00:15:00.560 fine all right so this is it we've got our minecraft server set up this is just one 00:14:58.399 --> 00:15:04.480 and we are ready to do a quick test so i just go now right yeah we're good 00:15:02.720 --> 00:15:07.480 for it good to go to tell you the ip but yeah scanning for games on your local 00:15:06.079 --> 00:15:10.839 network 6.180. 00:15:09.440 --> 00:15:14.639 nope 10.20.6.180 i know how to type in an ip 00:15:12.880 --> 00:15:19.920 smart guy i'm not saying you're stupid i just i'm firewall thing or something on 00:15:17.440 --> 00:15:22.959 a local connection well i mean Windows has a firewall thing i have to click 00:15:21.199 --> 00:15:27.120 away i don't know about your Linux oh my god maybe 00:15:25.360 --> 00:15:30.560 yeah i'm pinging you and nothing's happening 00:15:28.560 --> 00:15:35.040 did you just say you are an ass load you're an ass load hey i helped a thing 00:15:32.959 --> 00:15:39.120 you did i was just so astounded that the minimal install of this os comes with a 00:15:37.279 --> 00:15:45.600 pre-enabled firewall hey um do you want to fly do i want a 00:15:42.000 --> 00:15:47.680 what fly a fly do you want to fly no i 00:15:45.600 --> 00:15:51.440 want to i want to craft you just you hold the button you don't it takes this 00:15:49.839 --> 00:15:54.639 long to harvest one friggin piece of wood you're punching it with your hand 00:15:53.199 --> 00:15:59.279 well you tried to cut down a tree with your hand before yeah well then that's totally unrealistic for a completely 00:15:57.759 --> 00:16:04.800 different reason and wait why does the tree stay like this how does that work just like so is it 00:16:02.880 --> 00:16:09.040 just an automatically generated world yeah so there's like a seed for every 00:16:06.720 --> 00:16:13.600 world that's like what it's basically i understand what i see yeah type slash 00:16:10.720 --> 00:16:17.519 speed i'm gonna go really fast look at that world generate baby we 00:16:15.759 --> 00:16:21.279 haven't even overclocked a server either wow 00:16:18.959 --> 00:16:25.440 we ripping boys i'm gonna crank the server to like 32 render distance or 00:16:23.440 --> 00:16:29.600 something crazy like that i mean 32 seems like a lot why don't we just do 00:16:26.800 --> 00:16:34.160 like i already set it to 32. okay ah it's more it's uh it's chugging a little 00:16:32.800 --> 00:16:39.920 it's trying that's a lot of rendered ten ten of ten 00:16:37.120 --> 00:16:45.759 definitely trying oh no the poor server how's our CPU doing over there oh oh 00:16:43.040 --> 00:16:49.920 we're we're pegged at 100 we're at 100 okay so this is it this is peak 00:16:48.160 --> 00:16:53.519 minecraft server well we haven't even overclocked yet what do you mean so this 00:16:51.440 --> 00:16:56.560 is all being generated in real time this is very unrepresentative of what we 00:16:55.279 --> 00:17:00.399 would actually do oh yeah no this is totally unfair oh boy 00:16:58.880 --> 00:17:05.439 it's it's not having a great time right now 00:17:02.720 --> 00:17:09.600 it's trying woo there we go oh 00:17:07.360 --> 00:17:13.439 i thought it just froze oh no you're just letting it it's doing it i love it 00:17:14.959 --> 00:17:19.760 some of us are adults and have things to do Jake so stay tuned for part two we're 00:17:18.480 --> 00:17:24.799 gonna water cool that thing we're gonna overclock that thing and we're gonna get
