okay so where are we at with this so we just finished up like a day of
0:04
testing a bunch of different stuff on this with liquid metal and without liquid metal and now we're going to
0:10
put that guy right there on this
0:14
is the world's most unusual water block
0:17
it looks normal on the surface copper on the bottom plexi and metal on the top
0:22
but the secret sauce is it actually replaces the integrated
0:28
heat spreader of your CPU making direct
0:31
contact with the die
0:34
this is madness hopefully
0:47
private internet access is exactly what it sounds like the vpn that encrypts all
0:51
your internet traffic and uses a safe protected ip stay tuned to learn more
0:56
you know what's funny is we're kind of coming full circle here this actually
0:59
reminds me of the danger den tdx so that was a really old block designed
1:05
for back before AMD cpus in particular had
1:09
integrated heat spreaders so the secret sauce here really is just the way that
1:15
nude cnc has designed the base of their
1:18
block in the shape of the underside of an integrated heat
1:23
spreader so you can see this lip right here is designed to be
1:28
sealed onto the substrate
1:31
these right here are designed to be held by the socket retention mechanism and
1:37
then this flat surface right here you can actually see an outline from testing
1:41
they must have done at the factory this is a prototype unit you can see the
1:44
outline of where a die was making
1:48
contact with it before so how's the mounting work first we got
1:52
to de-lit it right yeah well this one's already been deleted not not right now
1:55
obviously but it should come off pretty easily so one of the big ways that
1:59
enthusiasts have been improving temperatures in some cases very
2:03
dramatically over the last few generations is removing the integrated
2:07
heat spreader from the CPU like alex is doing now and replacing the stock
2:12
thermal compound that's in there with something a little more potent either a
2:16
high performance paste or in extreme
2:19
cases even liquid metal but
2:22
the theory here is that nothing
2:26
i guess that's where the name nude cnc comes from yeah
2:30
nothing is better than anything
2:33
so we're removing a full layer of
2:36
thermal interface material and additional metal
2:40
between the water and the dye which is
2:43
where the heat is actually generated
2:46
this is freaking crazy like you look at how
2:50
thin everything we're dealing with is the tolerances for this
2:54
have to be so tight
2:58
which is why we're using a 7700k for our testing rather than an 8700k because as
3:03
far as we know that's what this particular prototype is validated on
3:09
it probably would work for an 8700k though probably but go back a couple of
3:14
generations to when Intel was using a thicker package material
3:19
and maybe not maybe you'd over tighten it which
3:22
i mean look at this thing you don't want to do
3:26
it's as thin as a chip um let's get some liquid metal off of
3:31
this first just for the like nice new application we already put a whole bunch
3:35
of conformal coating on this for everyone that's wondering i'm just gonna
3:39
give it the old shirt treatment here make sure it's nice and clean kids don't
3:43
try this at home certified esd safe yeah so we put this
3:48
in the socket first here we go
3:51
where's our dot i think it's this way
3:56
okay so here you can see what i was talking
4:00
about before where you do need some kind of ihs on it to even hold the CPU in
4:05
place because that's how these mounting mechanisms work see
4:10
there's far too much play in there you won't be making adequate contact between
4:13
the pads on the bottom of the CPU and the pins in the socket there's something
4:17
about german that makes warnings so much more fun
4:22
warning me to lumininium cooler copper
4:25
curtain vernon whereas like the english ones like warning do not use aluminum
4:30
heatsinks all right what's next so we apply this right in the socket
4:35
that's lots hey you can sort of get it in there and then just pull out and
4:38
it'll like deflate it's really weird
4:45
so this is the trickiest part you can see this notch is smaller and
4:50
it's offset compared to the one that's built into the integrated heat spreader
4:54
that is so that you can kind of start it over here
4:59
move it where it will actually be held down
5:03
and then tighten the whole thing down
5:07
this is crazy like that is crazy
5:13
yeah so now i guess we need to drain the sketchy loop
5:16
what so we need to put the fittings in there no no you don't have to drain the loop
5:20
to put in fittings why have you been wasting time in between runs draining
5:24
loops what's wrong with you that is how you break motherboards
5:29
he broke the dual socket c621 sage
5:33
a 700 board there is a crater in the
5:37
socket i don't get oh i see it
5:41
oh my god there's so much water coming out
5:45
how are you going to flip those around water everywhere water evaporates
5:50
do you want to at least pour some out i don't think these are gonna fit
5:54
yeah these don't work oh damn okay i'll get the zip ties
6:00
no you know what we could do is uh yeah
6:03
so we're just gonna go uh no callers on the compression fittings we're just
6:06
going to use compressions as standard barbs fortunately alex is gone right now
6:10
because i'm quite certain he would not approve of what i'm about
6:14
to do i'm just gonna
6:17
go for like a speed mount here oh no water
6:21
yeah yep okay
6:25
and if we go like oh
6:30
i lifted it too high maybe we can fix it before he gets back
6:35
okay hold on you're saying about not draining the
6:38
loop just gotta absorb the water
6:43
where's the power supply right below that below it now it should be fine
6:47
is that going to dissolve the tubing no
6:50
that's not going to touch the tubing i just want it on the board i need to oh i
6:54
don't want it in the block though not really oh it's in the block now okay
6:58
i just need it to carry away the water that's a
7:02
that's an acrylic block so that might ah
7:05
oh i really hope that this all survives
7:08
i'll be right back with an air compressor i settled for this it was a lot lighter
7:12
to bring up the stairs it's about to get really stinky in here
7:18
no no nothing got over that far oh wait yeah maybe a little oh oh yeah
7:22
it's way over there okay cool
7:26
no no you don't have to drink it to put in fittings have you been wasting time
7:29
in between runs draining loops what's wrong with
7:32
you i mean realistically after applying this kind of heat to it it's probably
7:36
drier than it was before
7:40
what are you doing smelling it
7:44
i'm still picking up some alcohol smell here that means it's probably not all evaporated look i wish i had all the
7:49
time in the world to do things carefully and properly it would have been like a
7:53
minute here we go
7:56
dang it hey that really gets the liquid metal going though hey
8:00
yeah i guess it's way more liquidy now yeah so let's put that bad boy on there again
8:05
what could possibly go wrong okay yep it's on there
8:10
okay having learned nothing
8:14
we're just gonna quickly quickly quickly see how we're quickly
8:18
doing that and quickly
8:23
yeah see i told you it would work pro move is
8:26
to tighten it clockwise so that that way you're tightening the barb as you
8:30
tighten your zip tie plug and pump plugging around i got this the right way
8:33
around right yeah okay good i am like legit excited right now
8:38
i am a bit concerned okay let's do it
8:42
does it have the switch yeah that's a memo k switch and oh it's power switch
8:45
okay it's just hiding there it is
8:49
we're gonna find out if it posts
8:52
that that'd be pretty funny hey breaking the board in between all the testing
8:59
there you go all the RAM is picked up see
9:03
no problem no problem
9:06
all right so what are we trying to beat here
9:10
so we're looking for uh 53.4 degrees is our average temperature
9:14
with the custom loop before okay
9:18
and that was with liquid metal that was with liquid metal that's the mark to beat i feel like Windows search has
9:22
gotten worse over time but somehow they did it i
9:26
agree with you stress fpu hit it yep okay
9:30
oh damn that's looking like it might be a little
9:34
better 46 50.
9:37
so what was the mark to beat max before was 58.
9:41
wow all right well let's give it half an
9:44
hour and make sure but this is looking really promising
9:48
okay it's been 23 minutes just doing a quick check in here everything all right
9:54
okay it's still up not only are these temperatures
9:58
outstanding but look at that spread
10:02
damn core decor temperatures are within like three degrees
10:07
and this has clearly stabilized
10:10
like this is it this is all we get
10:14
so with an average of 51.5 degrees we are almost a full
10:19
two degrees cooler on average than we were with our liquid metaled
10:26
ihs so remember that that's key
10:31
two degrees we dropped and
10:35
we haven't even overclocked yet
10:39
you ready so far everything seems to be behaving
10:43
totally normally oh we are at that clock speed oh it's
10:47
beautiful let's hit it
10:52
wow that's like the same temperature
10:56
like zero f's given about five gigahertz check this out
11:02
five gigahertz at 55 to 60 degrees
11:06
because remember this water is already pre-warmed like there's no way this has
11:09
had enough time to cool down fully wow
11:12
like look at the spread though that's what's crazy to me the
11:17
consistency kind of just try going higher
11:21
yeah we got nothing to lose
11:25
okay so how hard do we hit it i don't know it seems like some people are
11:29
getting like 5.5 with 1.5 volts so
11:32
okay i'm trying 5.4 at 1.5 volts we might be getting into
11:37
Windows at 5.4 no no we're not i mean let's just see
11:42
let's try 5.3 we're going to Windows
11:45
we are most certainly running at 5 i hate it when it does this
11:49
5.29 takes the satisfaction right out of it
11:54
wow so if we had a chip and a board that
11:58
could handle higher frequency with this kind of voltage
12:01
our cooling would still be well under control
12:06
look at that we have settled in at around
12:10
65 to 75 degrees on all four of our
12:14
cores so to put that in perspective
12:17
that is about what we might expect on a CPU like this at stock speeds with like
12:23
an adequate but unexceptional air cooler
12:27
so the conclusion here is both complicated and simple
12:31
the simple part of it is that the nude cnc
12:35
whatever this thing is called what's it called
12:38
encore performs better than
12:42
any water cooling solution that makes contact with the ihs even if your ihs is
12:47
liquid metaled the part that's complicated is that the
12:52
encore requires voiding the warranty of
12:56
your processor in order to achieve these gains
13:01
so we're not going to recommend it
13:04
but we're not gonna say that it's not
13:08
super cool either
13:11
in no particular order here are some reasons to use private internet access
13:15
one it hides your true ip address and geographic location two it allows you to
13:20
browse anonymous it allows you to browse anonymously
13:24
keeping your identity hidden which is especially important for political
13:28
dissidents journalists human rights activists etc three it allows you to
13:32
avoid data mining and targeted advertising four it allows you to block
13:37
unwanted connections with advanced firewall and filtering capabilities six
13:42
it allows you to unblock websites bypassing lots of get you know what the
13:45
point is there's a lot of reasons and it's super affordable
13:48

well as our community forum we will see you in the next video at least i will
14:09
you might not be there you did break that motherboard
14:12
but you spilled water all over this one and it isn't broken
14:16
um the one that's coming apparently is better than the one that i broke
14:21
gary's just trying to help you out he said to give me a bonus
14:26
he did not i'm on the email chain
