with only our own hard work and brains and an expensive 8k red camera alex and
i will now be finding out if in fact
you can water cool a red digital cinema
8k camera you have not test reassembled this have you i have not
all right so this is gonna be an adventure ladies and gentlemen ridge
wallet is the sleek way to keep wallet bulge down with its compact frame and
rfid blocking inner plates check out their new patterns and use the offer
code lioness to save 10 percent and get free worldwide shipping
uh yeah so we need to make one of these but the correct size
okay we also probably should leak test the whole thing before we you know
actually put it in the camera yeah minor details so this goes in the box
and we'll just you know take the little heat sinks put them
together just kind of assemble it all here fill it with water and see what happens okay so in front of us we've got
our radiator an alpha cool pump and then we've also got two basically uh
frankenstein blocks onto existing
cooling systems within the camera once we're done theoretically the entire
inside of the camera will be water cooled but we will still have the air
cooling fans running is this everything so this is our other water block and
also this bucket that's filled with the right camera
so i'm putting this on here is that right yep all right really helps if you
take the screws out of the radiator on the other side first oh i guess i should assume everything
about this project is kind of screwed probably the most stressful bit of today
is that we have to turn two of these heat pipes
into the correctly bent heat pipes like this
and we only have four of them and we bought the entire stock of them in
canada so and these are your previous attempts yep
these are that doesn't bode well yeah you're just guessing and checking do you
have another way to do it well i just assumed you had another way to do it
what do i pay you for 2.25 millimeters just give her a bit
more 2.12 let's
give her a little bit 2.08 actually we want to do a tiny bit
more you're going to overcook it i'm not going to overcook it
you overcooked it 2.01 millimeter so you're still over you
undercooked it that's that's what i said absolutely nailed it just gonna bend
this tube here you'd think that it's a bit more high-tech than it is but nope
we definitely could have made this ourselves instead of buying it but here
we go the hard part is getting two of them exactly the same you might be
thinking oh goodness that's going the wrong way
which isn't fantastic but we're just gonna bend it back over
here not recommended for sure
and there we go we have basically a
fully done heat pipe so this is our one that we know fits correctly even if
they're not totally bang on we at least have two more tries and we haven't totally screwed these ones up yet so
okay i'm back i found some fittings
thank you i need a wrench
do you yeah i can't get this off
do we not have an adjustable wrench why would you want that
um it's under nut rounders nut grinders
rounders also i already got the fitting off with my hands hey at least i managed
to find the right fitting smart guy i could have found those two but you
didn't this is gonna be a really tight fit you
know i can't get a tube in there like this hole should be
even a quarter inch that way
and i'd be able to get it in there these silicone hoses are normally used
for bending hardline tubing but fun fact you can actually use them to bend soft
tubing as well
this is going to work way better than i could have possibly
hoped zero kinkage all along the top here once it's
tightened down you can see that the o-ring is compressed so we shouldn't have any leaks shouldn't
that's what i want to hear so when i first planned out this loop the pump was
the other way around but it eventually had to be flipped there was a fitting
spot like a port on the top that was going to be used to fill the whole thing
which we now don't have access to could we just put a hole in here maybe but it
probably wouldn't look good there was a reason that i did it that way and i
don't quite remember what it was at this point so this is our sensor cooling
block i don't know if you've actually seen it in the flesh yet oh no i haven't did you hand mill that kind of looks
hand done this right here was all done with the router this was done on the
mill does that have a bunch of junk in it though do you mean like it looks like
there's like residue in it oh that's just a bit of lube is there anything
wrong with lube in the loop i just don't think lube is great for not gunking up
the water yeah that's that's fair i'll run a pipe cleaner through it now
because these fittings for the inside of the camera are so small there's nowhere
that they could really put an o-ring seal on them so instead we're using
teflon tape to seal up the threads um
now because we don't actually have a quick and easy way to leak test our
blocks we took one of those five-way manifolds that we didn't end up using
plugged four of them connected the last one connected that to
the block plugged the end with a pair of vise grips and now we can hook up our ek
leak tester here so i'm just going to go ahead and pressurize the loop and we're
going to leave it for a little bit and see if our block leaks
i don't hear anything needle's not moving i also want to make sure that
this heat pipe right here didn't collapse so the thing about a heat pipe
is you need to have the fluid inside able to move freely so if you
accidentally kink it and you impede that movement that can be a big problem for
performance so how do you test that then well i'd like to say that there's a good
way to do it but oh wait hold on a second
seriously yeah so heating up heat pipes can cause them to explode but presumably
you're not going to heat it up much right oh yeah my finger's getting pretty hot okay all right all right all right
our block is leaking but i don't think it's around the o-ring
i think it's around the fittings and i popped one of them out and that's
clearly not enough teflon tape so we teflon tape the bejesus out of these
fittings and it's sticking looks good
that's very good news because if it was the o-ring or something else about the
block design we were in trouble this is the one i'm more concerned about
like for the block itself actually leaking yep oh wow she is yep
ah i think we might have to submerge it sir
do we have a bucket of water uh we can make a bucket of water so it looks like
the leak is actually in the
fitment between the top cover and the bottom plate
i didn't want it to come to this but we do have gasket maker
we could just give her oh
so we might be so it's just not flat enough we might be able to skimmer all
right we have a lapping plate okay cool let's do it
round two here we go oh dang it really okay so we're boned
now i don't think we're boned while drilling this hole right here i went
down a touch too far so that means i need to go real heavy on the teflon tape
up at the top i was thinking that we could put jb weld in there and then
run a tap through i think this will hold
is this the mangled remains of one of the original coolers
yup this was the one we were planning to try to reuse isn't it yep
oh that that seems like a lot yeah oh yeah that is a lot
come on guys it's right here yeah but this one
is already in my hand
adjustable wrenches there's nothing wrong with them for a part that you're
going to use a couple times did we get it
no bubbles though i'm glad that we tested these beforehand
there's no way i was sticking this in a red and just like calling it a day oh i
think we've got a bubble on the right side oh yeah
water's a bigger molecule so if just a little bit of air gets out
that actually looks okay though yeah it does so do we get to reassemble this
damn thing we do yes okay what fan is this
that's the fan that's from the red we're replacing it with Noctua yeah
goodbye fans
one holiday later so our radiator and
pump have apparently been leak tested now
so that's a big difference from before and
we are basically ready to reassemble now is that correct yeah let's do it so i
think sensor is a good spot to start okay
i think we need our guide sure they could be in the unlabeled bag
how this went together was just like in my brain a month ago how bad is it if i
bend this heat pipe a little a little is not bad a lot is very bad all right
those are cranked on there hopefully the correct tightness yeah don't put that on
quite yet oh it's easier if we put the other one on first neat
so i potentially have some rather bad news this little thing that's
on top of the thing where is it i have no clue
i am concerned that everything was put back in the bins by not me here it is
it's right here oh it's just stuck to a bag okay good
i suspect this is temperature related it has to be
so that's on there you can hardly tell how
wonderful the epoxy job was once that's on there yeah i am so excited to find
out if this thing works better now yeah i kind of realized a little while ago
that we probably could have got like 90 percent of the improvement by just
swapping the thermal compound and putting in some new Noctua fans and we
probably could have found out if there was any purpose to this whatsoever by
just using chilled air at the intake and seeing if the image quality improves
yeah oh i see yeah oh that's really tough really tight yeah
so this has to go on here but this heat
pipe has to go over on this side but i have to put in a screw on the back of
this we're gonna have to bend your heat pipes alex no we have to nope
we don't do we have enough clearance there no i think you're right
okay yeah we gotta lock it off fun
oh i wonder if i can just use the pliers to turn the head of the screw alex i
wish these were spring-loaded can you get around it oh yeah there we
go okay we've defeated the nubbin so now we can do a double check here okay it's
not supposed to be a pry tool some of them even say it on the side have you
ever seen anyone use anything except for a flathead screwdriver to open up a
paint can yes they have paint can opening tools that sounds stupid
i don't think you actually put any in the holes really i guess that of the two
of us you have more experience you know critiquing others or well i was going to
say just like you have three children so the problem is that the implement's a
bit too big i also have a lot of experience with that problem don't miss
this this is the double penetration moment oh boy
oh we can't leave that in the video
okay i'll just get in there give it a little wipe this is how all the pro
chefs do it they just make an absolute mess on your plate and they come in with
a paper towel afterwards
should we wait for that to dry no okay
is there enough clearance for this heatsink yep oh you sound very confident
so mr david from a camera person's perspective uh which where do you want
the tubing coming out uh anywhere in those fans is fine anywhere yeah the
camera will sit on this yeah uh and so if this if it comes out here that's fine
so right side left side makes no difference to you okay and i bet if you just take out one
of them i can probably put both i don't know if the side cutters are
gonna work i don't know if you're gonna work did you not see the rack over there
when you came in what rock that's where you can check your attitude wow all
right so how long do we think this needs to be like that that's reasonable right
i would just make it longer just for fun sure i think
the hardest part is done and now we're just reassembling it if you know that
what you're saying necessitates a knock on wood
why would you say it drama for the video i guess
i don't need that drama what is the purpose of these labels i don't need to
know what they do i just need to it says like what it is on the stuff ah i see
wait what you got porton starboard confused
can we all agree that those connectors go right there
that does look correct yes
damn it alex where the hell does this go
you still have no recollection of this do you none at all
is it possible it's where you did all your cable management i think it goes
right in there oh crap wires kind of get managed so sorry i just poked it back
through that was my bad i i poked it with my feet oh geez yeah it liked it
though wow not required
oh balls oh easy easy easy easy oh did i go too
far you might have gone too far does it matter it doesn't really okay cool uh
editor could i get it so off comes the block again like just
like is it worth just like
getting a little bit more i know for a fact that engineers at red
will watch this video oh yeah realistically though guys this was the
best outcome you could have possibly hoped for yeah like even though this is
like in some ways the jankiest thing we've done in a really long time
in other ways it's the least janky thing we've done in quite a long time we could
just cut out all of the bad stuff editor
david senses something bad about to happen turns the camera on no i've got
this david hey shut up
you realize that ring's turning your mouth all blue
yeah but this is my dessert for my lunch i was a good boy i ate all my lunch
this is the one we needed to massage a bit i believe
i'd say you probably still need to do a fair bit there
that's so loud so much sucking
i'll lose my mouth right now uh eight out of ten blue
suck on that
uh so does it reach now
yes i knew that from the beginning i was never concerned at all that this
wouldn't fit how'd you even get that through there
jeez okay wi-fi antenna connected
fan connector number one
connected connected all right thank you for that ouch okay
uh should we screw this in no okay we're quite sure that this heat
pipe isn't going to touch the back of that pcb right
uh where's electrical tape
that's your solution it's not my only solution
perfect in yes perfect no
we can just use the pcb as we screw it down to push that heat pipe in the last
couple millimeters oh no
so problem you didn't think about how to get this out of the body we forgot you
forgot we forgot i never knew oh no
oh so
we're really close now so close in fact that andy is actually
tearing down the camera we've been shooting on so that we can steal all the
accessories and hook them up to this one
and find out if it actually works
so we're shooting on a plebeian canon
c200 now the side's completely closed up it's
actually looking pretty finished right about now you'd never know there was
anything funky about it other than the giant tubes hanging out the back all
right one two three here you go oh my god
now things getting sexy
here's the plan okay so
what
hi i'm being slow clapped right now what can i do for you
it was painted so nice so while alex is off looking for a funnel we're gonna
fill the loop the manly way why can't you just wait for me to go and get a
funnel and then we can do it right there's enough things that can go wrong here without you just pouring it
straight in the hole
he's back with his stupid funnel what a weakling oh crap okay power it off power
it off um how do i power it off you hold it oh whoa whoa hold on we got okay
power it off anyway power it off anyway i don't want to burn out this pump yeah just hold it down hold it down well just
pour what no i can't i can't it doesn't work that way the pump's not pumping
well it's not dead yet yeah
ah
let's just try to bleed the rad all right
is that working yep that's working okay
just bite it off
i kind of wish i had a bubble to watch move you know oh there it is oh yeah hey
some of it hey there's the rest of it there it goes oh yep yeah if that one
was in your vein you'd die okay
oh that was gross yeah did i just launch a snot rocket where'd that go i think it
went on the floor no i'll save you for later
so this is it then it's time to power on this camera and find out if we made it
better or worse and now you might immediately
point at the giant cooling box that we have hanging off it and say well it's
definitely worse but i would direct your attention to this
photograph of our camera operator would another box hanging off of him
really make a difference probably not so we are getting a fan
drive error but that's okay we knew that that was happening so whether that's the
knock to us up here or the pump or the fan here they might not be hitting the
RPM that red is expecting but in terms of the cooling performance we are
sitting at a mere 31-33 degrees right now so everything
seems to be working as we'd expect but red actually has their own built-in fan
speed control so when you're recording it should actually drop the speed of the
fan so just acid test time like are you ready
to find out well we're now recording
it doesn't seem to be dropping oh it's a setting oh alex what are you doing cutting the
low fan noise yeah you see that we don't need it it's loud right now let me just change
it to quiet mode outright that did not make it quiet you can put
your low noise adapter on it wait is this just a three pin fan
so i go ahead and press record now then right here we go we are now recording
8k footage hey
it's a mexican standoff
who's gonna shoot first trick question we're both shooting
already so i am locked at 35 degrees
right now damn 35.55
what are you at 38.55
so then i guess all that's left to do now is our full suite of temperature
acoustic and image quality testing to find out what if anything has changed
since we water cooled the camera i cannot believe that this worked this
was easily the hardest thing like the hardest project we've ever done but so
many things that we did just had such a high probability of not
working is it safe to say mission accomplished yet i'm still at 35 i think it's safe to
say i'm not 35 yeah we don't even need to do
a whole lot of other stuff we can just be like yeah here's the graphs it's
better for testing before and after we ran the
camera for 30 minutes in a climate-controlled room in both
situations our sensor temp stayed rock-solid at 39 degrees celsius which
is great given that changes in temperature can affect the image quality
slightly but what was really impressive about our
water cooled camera was the noise our initial test had the camera slowly
get louder and louder during the shot in order to maintain that sensor
temperature up to 46 decibels in our testing our
water cooled camera however never even got over the 34 decibel noise floor of
the office we were testing in that is damn impressive
huge thanks by the way to joe from solidworks for helping us with the flow
stimulations oh canada tool supply for supplying well many of the tools
alphacool for their tiny cooling components and of course Noctua for
their silent fans maingear's element gaming laptop is available at 25 micro
center locations as well as on amazon it features an Intel core i7 9750h
processor GeForce rtx 2070 max q graphics 32 gigs of RAM a 2 terabyte
NVMe SSD and if you buy it at your nearest micro center store you can save
an additional hundred dollars in fact you can even save an additional hundred
dollars if you buy it at a micro center store that isn't the nearest one to you
wow so check it out and other micro center specials at the link in the video
description i mean they're not going to check your id and make sure that it's
the closest one come on so thanks for watching guys if you enjoyed this video
maybe check out one of our other cool water cooling projects where we liquid
cooled a network switch that one was we thought that one was
challenging at the time yeah it's still working too it's in there yeah that's
actually running in our in our camera den right now and for a 10 gig switch
quiet really quiet
