come on you can go faster than that can't you
0:04
so you've just got your brand new pc and
0:08
you want to do some overclocking but that like that tiny air cooler that you have is
0:12
just not doing it so you could get like a radiator a pump and
0:16
a reservoir but all that's pretty damn expensive so
0:21
what if you just buy the block and hook it up to your sink
0:26
well Linus said that's a bad idea but
0:30
he's on vacation so uh we're gonna do it let's do it yeah
0:43
madrina's coffee blends specialty cold brew coffees into 15-ounce grab-and-go
0:47
cans for your convenience check them out and use offer code Linus to save 40
0:53
40 at the link below so
0:57
first thing we need to do here is just get some baseline reading so what do we have in here Jake so this is a Intel
1:02
core i9 7900x we got a titan x p
1:06
uh not p but pascal same thing we got ax1500i which is super overkill but
1:11
really what we need to look at is the temperatures here so in the hottest core
1:14
we're looking at about 56 degrees this is at the stock clock
1:18
um so i guess should we overclock it first no let's wait until we get the
1:22
sink going right yeah let's just see how it performs compared to the sink and go
1:26
from there and that's what that 360 ml ek water blocks rad
1:30
oh oh that's my favorite technique
1:35
just give her a good blow some stamina here
1:38
jesus dude i don't think it's gonna seal very well does it even stick to this does it
1:43
matter though i bet you if we put a fitting on that
1:47
end of the tube it would be easier to like mate the two metal surfaces
1:50
together oh why did you let it go
1:56
all right let's get stuck in the sink i'm going to get another fitting this
1:59
guy what an amateur hey i got it we don't need Jake okay we're
2:03
just we're just doing it
2:07
yeah
2:10
we most certainly do oh geez
2:15
this is a bad idea i'm gonna go get some tuck tape because i don't think that
2:19
your tape is good enough dude what happened last time you used tuck tape is there video footage of that it's leaking
2:25
yeah it got dropped it was fine until we put it under
2:29
pressure it was fine until it like needed to work and then it didn't
2:34
i don't think they engineered this around being able to do this okay
2:37
so do you want to hold it and i'll tape it uh sure let's cut a piece off here
2:44
what are you taping now it's our return our return valve
2:51
prevent that perfect
2:57
cool hurricane
3:00
and i guess you you don't have to wait for this to get up to equilibrium either
3:03
right yeah there's no equilibrium the water's not re-circulating we're just at
3:07
it oh my gosh
3:10
so at idle we're sitting at about 14 degrees
3:15
four so just how you get sub-ambient you
3:18
remember that stuff it shouldn't go up it's gonna go up some like a bit like
3:24
i'm my guess is 38
3:27
average that's really good though oh my god okay so we're getting
3:33
hottest core as of right now is 40 degrees
3:37
which is what like 16 below what it was before yeah 56 i think was the hottest
3:41
core before how's it going it's good do you like your water cooling
3:48
what is it it's the best thing you've seen all day
3:51
coming out of the tap yeah yeah
3:56
what's wrong with that waste
4:00
well it's it's not too bad but look but look
4:03
at our temperatures our hottest core on the 7900x is 40
4:08
degrees that's not very many degrees
4:14
wow riley you're so insightful i guess this is the best way to watercool a pc
4:18
after all are you ready three
4:21
two one go you gotta keep it straight
4:27
okay so we're gonna have to measure rate from the bottom of the meniscus
4:30
here
4:33
and stop so that was
4:38
11.8 seconds we'll be um using 150 liters per hour
4:45
so let's i think before we overclock that we can
4:48
take this to the next extreme how is it going to get better than this
4:52
so we can't hook it up to the fridge well but you know what we can do with
4:55
the fridge we can just take yonder bucket of water
4:58
okay so i'm kind of missing but you get the idea
5:02
so yeah we've got this 22 submersible pump so the idea is
5:07
basically we have a bucket we fill it with ice
5:11
we put the pump into the bucket of ice
5:14
then sink goes to bucket goes to pump goes to
5:19
the thing goes back to thing drains into the sink
5:28
oh we want that we want that over here why what what what is with you and putting the water back in the thing
5:32
because we're going to have really cold water so you want to have the cold water kind of like
5:36
doing its thing in here yeah then we're just dumping hot water into the cold
5:39
like we're it's not going to get like above ambien
5:43
the time it goes through there all right fine and i don't think we can keep up
5:46
with the pump with this oh this is true is there a speed setting on there
5:51
all right so oh my god pump is getting plugged in
5:58
now is that pump supposed to be submerged yes oh wow dude that thing is kicking
6:03
water dude these lines are so cold already
6:07
we're going to kill the CPU for sure no this board is going to be done
6:12
so we're sitting at about oh subscribe
6:16
dude we have a finite amount of time before this but yeah we're looking at about three
6:20
three-ish degrees so it's still sub-ambient oh
6:25
no okay so it's 22 degrees in here
6:28
yeah our hottest core at the moment is 24 degrees so we aren't sub-ambient
6:32
we're damn close like we're doing better than we did with the chiller and so like
6:36
the total cost of this whole thing would be like
6:41
a cheap aliexpress block you can get those for like 15 to 20 bucks and then
6:45
22 dollars for the pump you could probably find a cheaper one
6:49
and we are a solid what 30 degrees slower we wrapped 56 before
6:54
more than 30 degrees lower than a triple rad from ek
7:01
five gigahertz baby
7:04
90 degrees oh my god wait what i think cinebench
7:07
just keeps crashing so
7:11
i think that we need more voltage we have 1.4 volts what do you mean we can't
7:16
do more voltage it's crashing and the answer to crashing is more voltage
7:22
i think we need Anthony uh hey Anthony we need you
7:26
we don't know how to overclock oh
7:29
you know how to overflow okay kinda yeah sure
7:32
yep we're gonna we're gonna leave this up to you okay
7:36
see that's that's what i was hoping that non-committal answer would prevent but
7:40
okay okay see you later enjoy buddy okay okay that's the thing all right so
7:45
let's go ida the voltage so sitting at max of 11
7:51
degrees at the moment our uh voltage is 1.375 and one point or two
7:57
point one five input uh hey it's working ah damn it
8:02
doesn't work it's crashing no it dropped down to one point oh actually
8:07
oh it does work hey look at this there we go so we got a little lower
8:10
voltage but we're basically
8:13
at similar temperatures to what we started with except we're at five
8:16
gigahertz now instead of 3.9
8:20
come on baby oh damn it
8:24
dude there's so much water on those tubes now oh yeah geez
8:28
we don't have much time oh 4.8 ah come on baby
8:32
oh you you can do it we're at 101 on one core
8:37
yeah so it's immediately overheating we're still at 4.8 baby
8:42
no we can drop the voltage to like 1.35 i guess i am concerned this is a
8:47
processor yeah it might just not be a very good overclocker
8:52
i'm just so disappointed yeah well sometimes you can't have nice things i
8:55
guess that's part of the story right you bought all the stuff you can't just go
8:58
return your CPU because well actually you can definitely do that because
9:02
amazon but you're not supposed to just return your
9:06
CPU because it doesn't overclock well so i guess we'll get to the best we can
9:11
get oh i had xmp on oh so
9:15
sweet do you think that would hurt it
9:18
yeah david oh
9:22
oh oh we're screen capping ah did i do it did i do it what did you
9:26
change i changed everything to auto
9:30
wait what's our wait wait go go back to our thing what is our
9:34
we're at 4.3
9:38
why did it what what
9:42
okay so well this is disappointing all right
9:45
4.8 baby it's uh how did this
9:52
that's how you overclock x299 so there's no way at all that this could be done
9:56
with just regular water cooling no was that like 4.4 maybe 4.5 this right
10:03
here is definitely like what you put in your forum post you're like yeah this so
10:07
it works then yeah if you just want to get another four or five hundred
10:10
megahertz to hopefully 500 6 000 yeah
10:14
maybe 60 88 yeah almost 6 100. i think we can push it a little further you
10:19
think we can go further i think we're at 93 degrees there
10:23
well i think i'll try to leave the voltage
10:27
another 100 megahertz i'm gonna give her i'm gonna give her
10:32
1.385 oh god it just turned off
10:37
uh uh
10:40
let's unplug it oh
10:44
maybe it was fine our last kick at the can if we can't do this then oh
10:50
oh holy oh it's doing it no it's not it's done no it's done
10:55
so it's conclusion time i guess if your goal is to just get the craziest
10:59
in a bench score craziest 3d mark
11:03
maybe plug it into a sync is the way to go yeah this worked surprisingly well like
11:08
and d lid yeah yeah because we absolutely destroyed the
11:12
triple rad and the whole thing cost like 50 bucks
11:16
and you could probably do it for cheaper yeah if you get an aquarium pump from
11:19
like a hardware store you could probably or used buy one used actually don't do
11:23
it yeah probably don't do you need to create a beautiful website without the hassle
11:27

until Linus gets back i guess and we won't do things that are quite this
12:14
dumb but uh if you did like it hit like get subscribed uh check out oh where to
12:19
buy things below i guess submergeable submersible pump and some ice like
12:23
that's like merch like that yeah merch i'm actually wearing it and uh yeah for
12:27
the forum yeah so you can post your dank scores yeah please don't ever do this
12:32
but if you do tag at what is your twitter alex the
12:35
greatish alex the greatish and at jakku underscore tv because we want to see
12:39
the madness please nobody show Linus this
12:44
it's not dead though yeah it's wait is it still on
12:47
no the light is still on
12:50
god we should turn it off yeah we should really turn it off
