karen's graphics card was running at like 100 degrees idle while water cooled
but the water still has to run through this
graphics card and see how terrible it is can you see the floater right there
it moves around if you tip the card
the metal touched my skin but the problem that i have right now is
the plan was to just remove the graphics card from the loop put another graphics
card in there and then have the loop go through this non-powered graphics card
which would hopefully not add any temperature to the loop and then it would be fine but i don't even want to
run this computer on the full loop if it's this gunked up

at last my friends it is finally
finally here the conclusion of the whole
room water cooling system series of videos that we have waited
over a year since initially putting
these systems together to finally talk about whether or not the concept worked
whether or not in practice it actually worked and the wait is over only a
couple more minutes it kind of reminds me of that uh that bmw video that i was
teasing on social media not that long ago about the all-new one series drop a
like on the bottom of the video if you want to see us finally release that because i think we're very close
let's go so i want to do a recap of the concept for those who haven't been
following along the whole time our editing den is in a south-facing room of
the house that we have been running Linus media group out of for the last
year and a half and it gets
friggin hot in here so my brilliant idea was
what if we took all of our editing workstations and removed the heat from
the room via water cooling so it started
with redoing our editing workstations which used to be just a haphazard mix of
parts that we had left over from reviews and are now pretty much all standardized
so they've got n600 cases from cooler master water cooling by swift tech and
i'll explain why there's a radiator on the outside of the system in spite of
the whole room water cooling i'll explain that later
we've got 4960x six core processors those are extreme editions 32 gigs of
kingston memory ASUS x99 deluxe motherboards gtx titan blacks so those
are six gig vram cards we've also got cooler master v750 power supplies and
all of them except exiles which actually has two of these a quadro a 10 gigabit
nick and then a v 1200 because uh his system is kind of balls to the wall and
then each system has its own pump as well so the way that it all works is
that at the back we've got kind of a a tangle of of tubing going on here so
we've got quick release fittings here so we can either
connect to the radiator on the top which is running quite toasty right now or
to the whole room system and this was actually all done up by luke's dad who
did an amazing job of plumbing the
entire room for us so you can see the terminus station is actually over here
by nick van berkel's pc so every one of these systems has an inlet and then an
outlet and they all join together as you go around the room we actually left
enough space to have up to seven systems water cooled all at the same
time all on the same loop and in the
bathroom server room this is where the magic
happens so here's our mechanical and then uh uv sterilizing filters here is
our reservoir here are our dual little giant pumps and then those lead to a
radiator fan setup using Noctua industrial ppc fans so those waterproof
dust proof ones on the roof of the house
so that we are actually physically removing the heat from the building in
order to keep our systems cool we've got a cover on there we've got a power
supply for all of the fans to run as well
so with that recapped how does it
perform so to evaluate our success there's a number of different metrics to
look at we can look at the cooling performance of the individual systems
based on how hot their cpus run during an intensive task like video rendering
we can look at the room temperature inside versus the temperature outside to
see if removing the heat from the room actually yielded any kind of benefit and
we can look at the convenience and maintenance factors so let's start with
CPU temperatures when we're running the
cpus on their own radiators the room
reaches a temperature of about 31 degrees so you can actually see that
right now which is about a three degree difference between the inside and the
outside and you should bear in mind that that's on a day that's not particularly
sunny which can cause the room to heat up quite a bit more than the computers
could possibly affect all the systems
and the sort of 45 degree plus range on
the CPU which is reasonable except for terrans which i'll talk more about later
and edsels which has an additional graphics card but no additional radiator
space for cooling so that one's bound to run a little bit on the hotter side so
now what we're gonna do is we are going to take the running whole room system
i'll show you guys how we quickly connect and disconnect them
so while they're running probably not recommended but we've done it so many
times anyway that it i've lost all fear of the process
all we do is use these to hook it up
to the whole room system now
what you are likely to see here is a nearly instantaneous drop
in CPU temperatures so we've gone from 47 on core 1 to 41
and i'll make some graphs here showing you guys the difference in CPU temps
under load from system to system to dramatically reduce temperatures across
the board by hooking up to the whole room system why does that work well it's just a
matter of radiator capacity we could just as easily achieve great CPU
temperatures by hooking up much much larger radiators as you'll see in some
very large towers this will support like quad rads in the front duals in the top
a single in the back and the like another advantage of this approach by
having it outside is that you don't end up with a chain reaction of the room
temperature increasing and therefore the cooling efficiency of your radiator
increasing because you're always tied to ambient temperatures but
that's a great question if one of the objectives was to lower the ambient
temperature in the room with this system how much have you achieved the answer is
not a heck of a lot we achieved a one degree drop by hooking all of these
systems up which i would consider within the sort of margin of error the sort of
a vague sort of concept so being able to align this correctly helps a lot
on our inlet so that's the cold side we're getting 29.7 degrees
and on our outlet that's the hot side
we are getting 30.0 degrees which i'm sure someone out
there is calculating the specific heat of this you know mass of water or
whatever the case may be and i'm sure that we are actually dissipating a
significant amount of the heat outside but that is where the whole
was it actually practical thing comes into play because by going with copper
tubing which i think we can all agree is more aesthetically pleasing than
insulated pvc we actually created a situation where we are dissipating a
significant amount of the heat we're pulling out of each system
into the room anyway anyway via the copper piping
so i guess all that's really left now is
do we consider the project a success the answer is no um i still think the
concept could have worked really well but there were a few critical things
that i really think we could have done differently number one don't use a metal
reservoir don't use a metal reservoir
find some kind of plastic reservoir to use because that's where the thing that
i promised to talk about later comes in terran system has some big problems
caused by corrosion bits stuck in his system that even cleaning out his CPU
block which was extremely gunked up that was a picture i posted on instagram
could not fix and um
point number two is i would definitely recommend installing some kind of a
bleed system at the highest point in the loop that way you are not going to have
as much difficulty filling the system each time uh compared to
us where we had to add a second pump in order to have enough flow rate and
enough pressure in order to get the water in and the air out of our tubing
system uh the other thing that i would do differently next time is um
wow gee i guess that ties into a question that we've been asked a lot
aren't you guys moving why did you bother with all of this and are you
gonna do whole room water cooling at the new place well number one we weren't
planning to move when we originally came up with this concept and started working
on it so there's that uh number two no we do not
intend to water cool our systems let alone whole room water cool our systems
at the new office we're gonna have air conditioning which is probably the
solution that we should have gone with in the first place if the objective was
to lower the temperature in this room
and have our computers run cooler
so i think that's pretty much it thank you guys for sticking with us throughout the
whole room water cooling project we learned a lot i think we established the
feasibility of it the performance and the silence factor cannot be denied but
the convenience factor of it leaves a lot to be desired and the
the execution of it would be extraordinarily time consuming and even
more expensive than what we did if you were to really do it properly in such a
way that it would require little or zero maintenance over the long
run thanks for watching guys uh if you
