Immersion Cooling an S19J Pro ASIC miner with Bitcool from Engineeredfluids.com WHAT NOT TO DO! - YouTube
Channel: SPACE DESIGN WAREHOUSE
[0]
well i did it
[1]
i immersion cooled an s19jpro asic miner
[4]
it did not go smoothly whoa okay stop
[10]
and i did not pick up the right
[11]
components but i learned a lot and man
[13]
those temperatures okay this next part
[15]
is super important this project was a
[17]
proof of concept for the warehouse
[18]
mining farm and mostly i wanted to try
[20]
out this bitcool dielectric coolant to
[22]
see if it could deliver on the promise
[24]
of super stable temperatures with way
[26]
less noise than the hurricane room that
[28]
said we used the wrong pump the wrong
[30]
tubing material and a radiator out of a
[32]
2007 toyota corolla as a heat exchanger
[35]
this video will be filled with really
[36]
good information about immersion cooling
[38]
but do not do what i have done here my
[40]
name is nicholas johnson and this is the
[42]
space warehouse so i got a chance to go
[44]
out and meet the guys and lady at
[46]
engineeredfluids.com headquarters where
[48]
they make these dielectric coolants for
[49]
use in immersion cooling all sorts of
[51]
things from computer servers to ev
[53]
batteries to bitcoin miners i met up
[55]
with the vp of operations chad brune he
[57]
showed us around their new facility
[59]
showed us some of the older projects
[60]
they had made and some future whole kit
[62]
in a box options they're going to be
[64]
offering in the coming months he was
[65]
happy to answer all the questions i
[66]
could come up with and give advice on
[68]
how to properly put together an emerging
[70]
cooling rig for my asic miners advice i
[72]
promptly went solidly against for the
[74]
purpose of filming this video you're
[75]
watching now you see we're starting a
[77]
road trip today all the way up north to
[79]
meet in person with and verify the
[80]
identity of our new us-based mining
[82]
hardware supplier and i'm going to pick
[84]
up a couple more s19 jpros but that
[86]
meant i needed to acquire all the
[87]
equipment i needed to build this
[89]
monstrosity all in person and all in one
[92]
day so i could have it running and
[93]
tested before we take off on this long
[95]
road trip we started building it
[96]
yesterday there are some stipulations
[97]
when it comes to bitcool dielectric
[99]
coolant they have a list of materials on
[101]
their website that are compatible with
[102]
the chemical makeup of this stuff i'll
[104]
put a link in the description so you can
[105]
see what you cannot use with it all of
[107]
the proper components to build one of
[108]
these kits are readily available and
[110]
pretty easy to order and just wait for
[111]
them to arrive at your house but driving
[113]
out and buying the right stuff locally
[115]
and in person is not so i got a pump
[118]
that is way overpowered for the size of
[120]
this tank and i'm pretty sure it has the
[121]
wrong plastic inside that will either
[123]
just stop working or leak all over the
[124]
warehouse sometime when i'm not there
[126]
we're using clear vinyl tubing it looks
[128]
really nice and you can see everything
[129]
happening but soon it will become as
[131]
hard as glass and crack and fail i
[133]
couldn't find anywhere that would sell
[135]
me a dry cooler a proper heat exchanger
[137]
so what we have here is a car radiator
[139]
zip tied to an old home depot shop fan
[142]
which did a surprisingly good job of
[144]
dumping heat before springing a leak on
[145]
day one of its operation what i'm saying
[147]
is if you're gonna do a home brew
[149]
immersion cooling mining setup do not do
[151]
it this way but as far as how immersion
[154]
cooling works these are the general
[155]
components one needs in order to build
[157]
the system just build it with components
[159]
that won't self-destruct when they come
[160]
in contact with this magic
[162]
anti-electricity liquid you will need
[164]
some sort of tank mini gallons of
[166]
dielectric fluid i'm using bitcool more
[168]
on the properties of this heat sapping
[170]
wonder juice in a minute you'll need a
[172]
fluid pump to move the coolant out of
[174]
said tank ideally one made with all
[175]
metal construction a heat pump to remove
[178]
all the coolant you've pumped out of the
[179]
tank some hoses to carry the now less
[181]
hot bitcool back into the tank and of
[183]
course all of the accoutrements that
[185]
will go with these things hose clamps
[187]
thread tape cpvc glue a willingness to
[190]
be covered in warm oily substance when
[192]
something unexpected happens oh and an
[194]
asic machine you start by prepping the
[196]
miner first these fans are way too
[198]
powerful to be spinning under the
[199]
coolant you don't need them and you save
[201]
a few dozen watts by running the machine
[203]
without them unfortunately and also
[205]
fortunately the s19j pro is smart enough
[207]
to realize when the fans aren't
[208]
operating and it shuts itself off to
[210]
avoid self-destruction the way you get
[212]
around this safety feature is by using
[213]
these little fan spoofers or fan
[215]
simulators in this case i got these ones
[217]
on amazon i'll leave a link in the
[219]
description if you don't want to go
[220]
searching for them you're going to have
[221]
to pop off the top of the machine to get
[223]
the fans unplugged and the spoofers
[224]
plugged in once engineeredfluids.com
[226]
starts selling their immersion kit
[228]
they've designed this handle to make use
[229]
of the screw holes so you can more
[230]
easily dunk it into the bath without
[232]
getting your hands full of oil and
[234]
they've got some extra long cables for
[235]
the guts of this thing to make it so
[236]
that you can leave the control board up
[238]
out of the fluid so that you can reset
[239]
it or mess with the ethernet or use an
[241]
sd card easier and also this little
[243]
black custom riser to get your machine
[245]
up off the bottom of the tank and direct
[247]
the fluid up through it more effectively
[249]
unfortunately this riser wasn't designed
[251]
for this tank so joey and i had to make
[253]
some modifications in order to get the
[255]
flow going in the right direction now
[256]
that the machine is prepped the pump is
[258]
hardwired in and the radiator is
[260]
zip-tied to its fan it was just a matter
[261]
of getting the bit cool into the system
[263]
and checking for leaks this time this
[265]
stuff came in a bucket pouring it was
[267]
easier no more managing this jug like
[268]
when i did the gpu immersion i made it a
[270]
little more difficult for myself by
[272]
putting the tank so high up for display
[274]
purposes you'll notice the tank is
[275]
higher than the pump to provide a little
[277]
gravity assist for priming in the event
[279]
that you need to turn it off for any
[280]
reason the pump will stay primed the
[282]
fluid went in without any obvious
[283]
problems a guy could say i was a bit
[285]
surprised that nothing leaked
[286]
considering there was about 20 possible
[288]
joints that i could have glued the cpvc
[290]
wrong or just slid a hose over the end
[292]
of the pipe and clamped it down hoping
[294]
for the best chad tells me that this
[296]
fluid has tiny molecules even tinier
[298]
than water so this coolant will find a
[300]
leak if there is one that said we had
[302]
the system filled up we turned it on and
[304]
very quickly found a leak
[306]
whoa okay stop
[309]
[Music]
[313]
in my head this pump was basically gonna
[315]
push the coolant up and dump it into the
[316]
top of the radiator where it would fall
[318]
through the radiator and come back down
[320]
into the tank hence the radiator being
[321]
up so high well i didn't account for the
[323]
fact that i bought a pump that was about
[325]
five times stronger than what i needed
[326]
for what i've built here it immediately
[328]
pressurized the system found a leak in
[330]
the front of the radiator and then shot
[331]
a bunch more out the top this thing
[333]
didn't come with the radiator cap and it
[335]
didn't occur to me to buy one for
[336]
whatever reason so with a quick trip
[338]
back to the o'reilly auto parts a new
[340]
capped radiator zip tied into the system
[342]
and we were back off to the races this
[344]
time we started it back up and
[345]
everything was humming along perfectly
[347]
only one thing remained to do stand on a
[349]
chair covered in oil and awkwardly hoist
[351]
one of my 11 thousand dollar machines up
[354]
and into the bath you can just dunk the
[355]
whole thing in wiring and all it's quite
[358]
an unnatural thing to do especially
[359]
knowing this thing runs on over 3000
[361]
watts of electricity but doing unnatural
[364]
things is becoming increasingly more
[365]
common for me on this youtube channel so
[367]
here we are and now the moment i had
[369]
been waiting for since having medium
[371]
success with my gpu immersion experiment
[373]
which is still running
[378]
poof
[380]
success
[382]
outlet
[384]
it's a pump
[385]
pump
[387]
to radiator
[388]
radiator
[390]
back down
[391]
to
[392]
inlet and then inlet
[395]
back up
[397]
out the top
[398]
spilling down
[401]
no leaks no errors the machine turned on
[404]
found its network and found its pool and
[406]
just started hashing away the green
[407]
circles were normal normal normal and it
[409]
even started hashing at 107 terahash
[411]
this is a 104 machine initial running
[414]
temperatures were in the 40s and 50s
[415]
celsius of course this was just because
[417]
none of the coolant in the system had
[419]
found its equilibrium yet hadn't been
[420]
heated up yet we decided just to let
[422]
this thing run for a couple hours while
[424]
we went out and got some barbecue with
[425]
sarah the only hurdle left was just to
[427]
see if this little radiator can keep up
[428]
with the heat produced by an s19j pro
[431]
after a few hours the temperatures
[432]
stabilize with inlet temperatures in the
[434]
50s c and outlet temperatures in the 60s
[437]
this is amazing my air cooled machines
[439]
are in the 60s and 70s and that's normal
[441]
temperature i took a little four second
[443]
video of this disgusting mess i had put
[445]
together and sent it over to the boys at
[446]
engineered foods.com much to my surprise
[449]
and only a few minutes later this was
[450]
after business hours on a friday my
[452]
phone rings and it's the ceo the vp of
[454]
operations and the lead engineer on a
[456]
conference call telling me to
[458]
immediately shut down this system and
[459]
that i have put my equipment in imminent
[461]
danger all these bubbles you can see
[462]
flowing through the system are bad they
[464]
will cause problems with the pump
[465]
they'll cause problems inside the miner
[467]
as they're making their way up through
[468]
there the bubbles can get stuck in
[470]
little crevices and ruin the heat
[471]
transfer effect of the fluid and this
[473]
isn't even to mention that i used all
[475]
the wrong materials basically throughout
[476]
the entire system and car radiators who
[479]
knew are designed for water and
[481]
automotive cooling this system was a
[482]
beautiful proof of concept and it was
[485]
doomed so just as quickly as we put it
[487]
together we went back to the warehouse
[488]
and decommissioned my immersion cooled
[490]
s19jpro i just can't wait to build an
[493]
immersion cooling system with all the
[495]
proper equipment and specs so why would
[497]
someone want to do this at all why
[498]
immersion cool when air cooling seems to
[500]
work just fine for me i see two main
[502]
reasons to do this one you can make
[504]
these hoses basically as long as you
[505]
want and in reality you should use a
[507]
hard line cpvc it's chlorinated pvc pipe
[510]
but and not only are these components
[512]
about one tenth as loud as air cooling
[514]
is anyway you can run these hoses you
[516]
can run these lines outside and have
[517]
your pump and heat exchanger outside
[519]
your house which would leave you with a
[520]
bath full of miners indoors running
[522]
perfectly quietly and with almost no
[524]
heat the second reason to do this is for
[526]
longevity two of the main factors that
[528]
lead to these machines failing are heat
[530]
fluctuation and vibration when there are
[532]
heat fluctuations throughout the day
[534]
with air cooling because of the
[535]
environment day and night and all that
[537]
stuff the different materials that are
[538]
in contact with each other aluminum and
[540]
copper and silicon from the chips for
[542]
example contract and expand at different
[544]
rates from each other because of their
[546]
material mechanics this can cause tiny
[548]
microscopic cracks that gets compounded
[550]
when you have four extremely powerful
[552]
fans just vibrating away 24 hours a day
[554]
speeding up and slowing down as they
[556]
need to with the temperature fluctuation
[558]
but when your machines are bathing in a
[559]
tank of coolant the tank will stay very
[561]
close to the same temperature all the
[562]
time the temperature fluctuations will
[564]
happen in your heat exchanger you'll
[565]
adjust the fan to speed that up and slow
[567]
it down and any changes in temperature
[569]
that do take place happen very gradually
[571]
also the fans are removed so there is no
[573]
vibration unless you buy a giant pump
[575]
and use it with a tiny tank and just
[577]
blast bubbles up through the machine
[578]
don't build one like mine thirdly
[580]
someone's gonna come out with a way to
[581]
overclock these bad boys and soon and
[583]
when they do heat mitigation will become
[585]
your number one focus in running them
[587]
faster than they were designed to and
[588]
with a properly sized heat exchanger you
[590]
can keep these things basically as cool
[592]
as you want pretty much however hot they
[594]
try to get engineeredfluids.com is
[596]
working on a kit right now that they
[597]
want to have ready to ship let's say q1
[599]
of next year chad was a little unsure of
[602]
the exact date that they'll be ready for
[603]
the masses but this kit will come with
[605]
literally everything you'll need a tank
[606]
a properly sized pump a dry cooler heat
[608]
exchanger and all the fittings and
[610]
wiring you'll be able to just put it
[612]
down fill it up and plug it in goodbye
[614]
hurricane rooms and now we're off to
[616]
minnesota i'll be editing this video in
[618]
the back seat of a truck on a 1500 mile
[620]
journey to a frozen land to meet two
[622]
strangers in a parking lot where i will
[624]
exchange 20 thousand dollars for 80
[626]
pounds of computer equipment i'm really
[628]
digging the cyberpunk nature of this
[629]
timeline we're living in
