to answer the question once and for all whether you can water cool
an air cooler hold on we got to get all the fins alex
what'd we get 85
nice what kind of motherboard has nowhere to
install a CPU well no motherboard all motherboards need a CPU because
otherwise what would do the processing but if you look at this one
there's something a little unusual about it right you got your pci express
sockets you got your memory slots and you got just a blank metal plate
that's because the CPU socket is on the
back but why well as it turns out this motherboard
was designed with some pretty unique cooling concepts in mind and i for one
cannot wait to try it out
and i can't wait to tell you about our sponsor dot tech dot tech domains and
namecheap are donating 100 of all sales proceeds from dot tech domain sold until
july 5th to code.org to help make computer science education more
accessible check out go.tech LTT to
learn more
other than the CPU socket being on the opposite side the antec rev q270 is a
pretty standard looking industrial motherboard what i can't say the same
about is the heatsink that they designed for it and
in order to explain why they thought that this
was the best solution i think we're going to have to back up
entec is a spin-off company of edac electronic technology co who specializes
in inspection equipment for electronics manufacturers like foxconn panasonic and
sony aka these guys are the badasses that do the engineering work that lets
other engineers test their engineering work and for their inspection equipment
edac needed to have ultra-stable computers that are basically impervious
to dust so logically they just went ahead and
designed their own motherboard and flipped the CPU socket around you see
when you're working in a manufacturing or fabrication oriented space there's
nothing you can do about the fact that there is going to be some dust in the
air and unlike in your bedroom we're not talking about cat hair we're talking
about potential metal filings microscopic ones floating around in the
air which can eventually cause enormous problems for a computer that's why in a
workshop passively cooled machines like this one from compulab here are king
even slow spinning fans with an excellent dust filter are going to
quickly get clogged but to pull off this
little marvel compulab had to create an entirely custom chassis motherboard and
actually a fair number of other things so edac wanted to create something that's a
little more modular and a little more affordable which explains how we ended
up with a standard atx form factor motherboard but it still doesn't explain
this well the thing is to passively cool a
CPU even one that's not terribly powerful you need a lot of metal and
edac wasn't able to fit a big enough cooler on the front of the case while
still allowing for pci express expansion see that so after putting in the work to
create this motherboard for their own uses edac thought well i mean
yeah what if somebody else found this useful
thus eggtech was born and we were able to get our hands on this motherboard so
let's try it out wait we are going to submerge it in
water right well yeah
sorry not that well yeah not that one not that oh but but the thing yeah oh
good just making sure
everything about this feels wrong starting with flipping over the
motherboard to install the CPU uh
we're going with a core i7 6700k this is
near the top end of what this motherboard can support but we're going to try a 7700k a little bit later
and oh this is an interesting note uh is
there no cooler for the chipset i don't know actually there is
oh wonderful hey look at this when i see stuff like this it makes me wonder if
the engineers at anc tech aren't uh watching LTT because we have said a lot
of times it's baffling given how shamelessly computer companies rip each
other off that more of them haven't just ripped off knocked to a secufer mounting
mechanism and that's basically what this is except with kind of a clever cost
saving measure so they use an o-ring here to secure the back bolts instead of
having them be press fitted which is just kind of cheaper but a lot better
than having them just flop around like a lot of other guys do
there we go oh huh well didn't think of that
look at this brandon there's so much space back here because
of like the io and stuff that you can't just you can't just put it here and then put
it down on the box i guess i just have to do it like this
then like is this how you did it not even
close oh all right well this is how i'm doing it
all right there we go
can i get that chipset cooler by any chance i'm going for the no-look catch
oh what the who does that
i threw it at my head this is a very wimpy heatsink
considering that it is designed to be used with a passive CPU cooler
not much to it and
no way
it's just not a line they just used a generic
whatever this spacing which is pretty standard heatsink and it doesn't
actually line up with the little like silkscreen marks they made for where
it's supposed to sit another cost-saving measure
is that it doesn't come with a cmos battery so you'll just have to get your
own uh cr2032 three volt cell and pop it
in really guys
okay it's not designed for end users clearly
let's go ahead and pop this it's in the one
oh that makes sense yeah because like well can i just put it on for
temporaries i just want to i won't even put thermal compound on for
now i just want to see um oh i need a screwdriver no look catch
no we're not doing that thanks
man if they just sold this heatsink this thing is like badass look
no idea if the performance is actually any good but it's definitely badass
looking looks awesome are we like at the point
of diminishing returns though being this far away from the CPU i guess not with a
passive heat sink i see we've gone with trident z royal
dims because i guess we're going for the most
thematically coherent build of all time
now all we need ah is a case
large and hefty enough to accommodate this flippin beast and as alex alluded
to before there is no case hefty enough to fit this heatsink
through the motherboard tray while you're installing the motherboard so
we're gonna go ahead and pop it off now everything about this feels
just kind of wrong you know i've built so many computers in my life and this is
the first one like this this is a thanks i hate it and a half
like cursed motherboard you have against this thing it's just
i had nothing against it i was super excited about it until i had to actually
like touch it you know it says on their website that it fits most cases on
summer fire modification yeah we tried a few cases and lots of
them interfered with the top of these heat pipes and i think having your
compatibility list account for people doing modifications to their case is
kind of cheating because with a dremel theoretically anything is compatible
with anything oh
that looks awesome i mean
by the time you hack a hole in your side panel it's
probably not going to be the cleanest mod ever done but
the potential's there well let's get occt running right this
is a CPU stressing tool that will allow us to see
just how well that heatsink can keep up with a 6700k
hottest cores up at around 65 degrees
right now it's not even hot to the touch yet
there's just so much metal
right up at the top of those heat pipes there but you can also really see what a
great job heat pipes do of moving heat around it's not that much cooler at the
very end of the heat pipe it's really even meanwhile over here you
can see that with every load spike temperatures were peaking a little bit
higher than before until now
you know what probably happened the tiny bit of airflow from me moving the case
around probably caused it to go down a little
bit let's keep it still again it steadied at around 80 degrees on the
hottest core which is not what we were expecting based on either inktext
testing or steve from gamer's nexus's testing however we have observed that
our CPU is only running at around 3.45 gigahertz so we're thinking maybe
there's a biosetting that's not allowing it to run at full power let me go ahead
and try that yeah we got turbo working and
it can't do it we managed to thermal throttle within
about two or three minutes but
entec doesn't say you can do that and it's a pretty easy problem to solve if
you want to just throw a big 200 millimeter fan on here but
steve from gamer's nexus already did that we have other ideas
okay not too much because remember this has some oh my gosh this feels really really
really wrong what we're about to do right now
all right oh okay
all right i will lift it oh crap i'm stuck
i'm snagged dog our power cable is cable tied
lttstore.com baby get them cable ties okay
okay oh this feels so wrong wait where are the CPU temp set
uh oh it's thermal throttling right now okay
here we go
okay is it fine i mean
theoretically it should be fine
oh wow
down to 74. now that's water cooling boys
okay so we're at about 70 degrees i think we can do better
okay phase one lift the computer uh i think
getting on the table might be the best solution i think that this table is on
wheels and that's
it's still running okay um no yeah no you're not getting on the
table alex you ready yep yeah go ahead lift it
okay you're gonna have to have it for a little while though
what's that
not good did it power off firing back on
hold hold i'm holding okay one second
i just need to okay wait i just need to wait hold on i need
to oh god
all right there is
ah there's water hold on you gotta put it over this one
okay i got your second bucket here
okay we you know what we've got a little bit of submersion but we're gonna have
to add some more water i'm gonna start another render
should be fine we're learning so many things today that
will never be applicable to anyone else ever again
small problem alex yeah i think i may have actually splashed the vrms over
here when i rocked it back and forth can you see that
yeah it's water okay well that might explain why it was
crashing under load
i'll put these in for fun while alex gets a bag of ice
this is so cool you can see the very end of the heatsink
is a little bit cooler and you can kind of see a halo of
warmth around it in the water hey brandon check this out we were
trying to stick a thermal probe in the water near the heatsink to kind of see
how close these values are and it kept reading exactly the same as far away and
what we realized is it takes such a small disruption to
move these warm areas of water that you basically can't measure it by physically
sticking something in watch this watch this okay i'm gonna blow on the surface of
the water
that cool wanna get a shot of the premium ice
get the ingredients please
all right just got it this bag's just gotta give birth here
birth bag no i got this
when this hits it are we gonna have a titanic failure
you'll have to excuse me for not knowing how to use a bag of ice i don't
entertain much
i don't have any friends alex invited me to a super bowl viewing
party once though that was kind of him yeah you brought your kids it was really
cool okay so we're currently at 92 degrees
celsius uh-huh
oh okay
there's uh there's four ice cubes stuck under the heatsink
this is so stupid well look come on it's i don't make the
rules around here brandon so that puts us at around 60 degrees
but i think we can do better because as we've learned
even just small differences in location or flow
can make a big difference to the actual temperature so right up here it's like
0.7 degrees and then you go you know
what to eight to nine centimeters lower and you're at eight degrees
if only there was a way that we could move the fluid around inside the
container you think of everything don't you
how fun is this okay let's add a pump
this is a submersible pump do you want to go ahead and plug it in on the other side uh sure uh and i'm just gonna yolo
it i guess right okay
the power cable's only in there a bit should be fine i mean the pumps power
cable is in there too what could go wrong
okay that seems like a good spot oh that's
chili it's a chili boy oh it's splashy oh it's really splashy
alex hold on turn it back on turn it back on i'm trying to show the peeps
uh yeah that's a little splashy for my
liking uh i don't know let's find out
maybe if it was just the right amount of splashy
is it still blending it is but i think the temperature is
like the same that kind of makes sense because it was coldest at the top no no no it's
trending down look it's totally trending down
and we're still at 4.37 you can totally
see the water like touching the base of the
heatsink
settling in at 56 degrees on the package full load
pretty practical right yeah for sure
and you might get the opportunity to daily drive a cooling system like this
because they're actually releasing a more gaming oriented i guess product it's
based on a z490 chipset so um
yeah and we could probably come up with
something better for daily driving couldn't we i think we can we will we
will i promise make sure you're subscribed and make sure you check out
