hey welcome back to tech shinji
in this video we're going to go over the parts breakdown of this rig
and go over some little nuances and what i found in my experience building
it and just why did you water cool it the first part we're going to go over is the cpu
i get so many questions about the cpu is a core i3 enough shouldn't you use a core i7 shouldn't you use a
core i9 when it comes to mining you really don't you really dont need like any cpu like, like at all you could use
like a 10 year old cpu and they work totally fine the secret why well guess what so in a mining
rig the cpu is more like a traffic light all it does is direct traffic and information coming out
of the pci lanes of the gpu that's all it really does it gets more technical than that and does a
whole bunch of other things but in reality the cpu really doesn't do much a core i3 9100 is probably
an overkill for this rig you really don't need it you could probably gone with like a dual core 5400
g or something similar to that the cpu on this rig is also air cooled with a stock cooler another
major component is the motherboard msi h310 a pro atx style motherboard the reason why i went with
that motherboard is it has seven pcie slots in it one full 16x and six 1x slots that allows me to
put seven gpus in it why did i only pick that many well this is what we call a residential miner i
wanted higher power density if i'm using powerful cards i'm not going to put seven you know RTX 3090s
in here i wouldn't be able to run it off this one 1600 watt power supply and that's a good Segway
into our power supply evga t2 1600 watt titanium rated power supply the reason why i went with
such a high rating power supply is i wanted the best efficiency possible so power supplies
tend to be most efficient when they're loaded 50% to 75% of their rated capacity this machine
here pulls anywhere between 1100 to 1200 watts the reason why i only went with that number is because
this is what we call residential miner it's going to be in a residential setting like in a house
in the united states we have 15 amp 110 volt outlets with a maximum 1500 watt draw now you can
do that temporarily for like a spike or starting up but you generally don't want to load the power
100 full time you want to do what we call the 80 rule for safety this is only taking 80 percent of
15 amps which is around 12 amps it does not take more than 1200 watts full time that's the reason
why i went with the evga t2 1600 watt power supply another part that i get a lot of questions about
are the gpus themselves what are they does that void the warranty why did you choose it why did
you water cool it why did i water cool it i'm not sure probably because i wanted to waste my money
i have no idea these are actually power color liquid Devil 5700 XT's as you can see i got
the boxes right here yep that's right these are seven power color liquid devil 5700 XT's these
gpus come from power color with the ek water block already pre-applied you don't have to put it
on yourself it's literally done for you from the factory if i were to get a different type of
gpu i could always put the water block on myself as long as it's compatible and that does not void
your warranty at least with most gpu manufacturers what actually does void your warranty is if you
apply it improperly or you do something wrong or you dunk the thing underwater you know obvious
things it is harder to honor a warranty with something like that because you got to keep the
air cooler you got to put the air cooler back on when you send it in warranty generally it's pretty
okay as long as you know what you're doing the way i have things set up in this rig the gpus have
anywhere between 35 to 48 degrees celsius range of operation and temperature why the big range
well it really depends on the ambient temperature if the ambient temperature is right around 60
degrees fahrenheit or 70 degrees fahrenheit gpus run at around 45 degrees which is pretty good
this thing's been running at 100 the whole time you can hear it you can hear how loud my
voice is i'm talking kind of loudly right now but you can clearly hear the rig it's not that
loud you can still hear it yes it's not dead silent but yeah it's pretty quiet now we're
going to talk about the liquid cooling system the liquid cooling system comprises of
coolant's quick disconnect fittings are up here these quick disconnect fittings are double shut
off fittings which means when you disconnect them flow stops on both ends so they're double
shut off dry brake fittings you don't have to drain the entire rig in order to remove one gpu
say one of the gpus has a problem you can simply power down the rig disconnect the gpu turn the
rig back on have it continue to mine while you try to troubleshoot the problem with that one gpu
this is an ek distribution block right here all it really is is delrin block with a bunch of g1/4
threads machined into it i'm using dual ek d5 pumps which are water lubricated they're
pretty quiet and they're very reliable i mean i think the meantime between failures is like 1500
hours or something it's quite a bit they're pretty good the radiator is a 480 millimeter alpha cool
full copper radiator in the back 480 millimeters by 30 millimeters thick and that is being cooled
off by four noctua 120 millimeter fans i have one more radiator on the bottom here alpha cool
280 millimeter 45 millimeters thick radiator full copper of course and there's two noctua 140
millimeter fans on the bottom blowing up the air blows this way across the 480 millimeter radiator
going through the gpus and exhausting this way we got exhaust going this way and exhaust
going this way as for the tubing this is 7/8" by 1/2" diameter tubing all the pcie cables
are cable mod and they're custom lengths so each cable is custom length for every gpu going
right to the power supply there's no slack everything is in perfect length now the part that
everyone asks me about how much did it cost how much money does it make why did you water cool it
i did this for fun this was a passion project i took roi return on investment put a little box and
tossed it out the window obviously if i wanted the lowest roi time i wouldn't have done it this way i
wanted high hash rate i wanted to be quiet i also wanted to be cool and this achieves all every one
of those things now is it worth the premium well that depends a lot of people ask how much this
rig costs prices change on everything all the time especially at the time of filming we have human
malware going on right now that's causing computer hardware prices to go through the roof i have
attached in the description below the pc part picker list with every single part that was used
on this rig there's over a hundred individual components so i'm not gonna go over every single
one gpus themselves they're all the same gpu you can use that list and calculate the total price
how much you would cost for your situation another question i get is how much does this rig make how
much crypto are you getting well that's another one of those things that changes literally from
day to day you can actually calculate that number yourself between 380 mega hash and 400 mega hash
take that number and use your own electrical rate go use any ethereum mining calculator type those
numbers in and then you can see for yourself what kind of earnings you'll be getting with this rig
if you have any further questions about this rig or kind of how i built it if you have questions
about mining questions about water cooling feel free to leave a comment down in the comments below
and i'll try to answer you as soon as i can you can contact me on discord you can join our discord
server right now it's called mining misfits i'm actually in the server with chump change he's
the one in charge of the server i happen to be part of the server i'm a mod on that server so
if you want to talk to me directly that's the best way to talk to me or contact me if you have
any questions you can ask me there directly and i respond pretty quick at least in that server if
you like what you see here don't forget to get subscribed and let us know what you thought
about this video we'll see in the next video hey so you
