00:00:00.120 --> 00:00:06.440
you ever see those videos with thermal goop all over the CPU socket or people

00:00:04.680 --> 00:00:11.360
jamming things into high-powered fans and thought hm what would happen if I

00:00:08.440 --> 00:00:15.559
did that to my PC well that's bad first of all you could get hurt or worse you

00:00:13.480 --> 00:00:19.279
could damage your computer so instead of risking it let us indulge your intrusive

00:00:18.000 --> 00:00:23.199
thoughts like what would happen if you used your monitor in the Arctic can

00:00:21.279 --> 00:00:28.920
liquid crystals freeze we're about to try all of this and more but my friends

00:00:26.320 --> 00:00:37.280
heed this warning do not try this at home instead try this segue to our

00:00:32.440 --> 00:00:39.160
sponsor Ridge okay drop everything our

00:00:37.280 --> 00:00:43.960
LTT circuit board Ridge wallet collaboration is live designed by our

00:00:41.920 --> 00:00:48.640
very own Sarah but it is sure to stand out and hold up too thanks to ridge's

00:00:46.559 --> 00:00:53.600
meticulous focus on quality grab one today using our Link in the video

00:00:50.600 --> 00:00:53.600
description

00:01:01.120 --> 00:01:08.360
in theory modern highquality pastes are

00:01:04.199 --> 00:01:11.720
both non-conductive and non-capacitive

00:01:08.360 --> 00:01:13.680
so this might work okay but even if it's

00:01:11.720 --> 00:01:19.240
non-conductive wouldn't that block the pads from touching my theory is that the

00:01:16.240 --> 00:01:21.119
mounting pressure is going to be so high

00:01:19.240 --> 00:01:24.159
that it's going to kind of mash it out kind of like when you mount a heat sink

00:01:22.600 --> 00:01:29.320
and it's not mashing out as much as I might have hoped but there's a lot of

00:01:26.720 --> 00:01:33.600
mounting pressure on the CPU and these are older larger pins uh and guys this

00:01:32.280 --> 00:01:37.600
was already a motherboard that was a little bit flaky don't worry we want to

00:01:35.720 --> 00:01:40.640
sacrifice something that works perfectly Works enough to find out if it

00:01:39.759 --> 00:01:46.280
works though shut up no

00:01:44.240 --> 00:01:50.759
way clearly we haven't put enough thermal paste in

00:01:48.280 --> 00:01:55.119
oh for round two we're bringing out the big guns all right that should be enough

00:01:53.600 --> 00:01:59.280
that she's going to squeeze out like toothpaste or peanut butter

00:02:00.880 --> 00:02:10.760
no this is crazy oh boy okay I think this is our

00:02:08.160 --> 00:02:15.680
final stage here our ratio of thermal paste under

00:02:13.560 --> 00:02:20.239
the CPU to thermal paste on top of the CPU is extremely

00:02:17.879 --> 00:02:24.000
high so we should probably get some more paste on top yeah that's good that's

00:02:22.080 --> 00:02:29.160
good you know you've always wanted to try it no what if we run something like

00:02:27.319 --> 00:02:35.879
actually CPU intensive like cinn bench or something sure I can do that 62° on

00:02:32.920 --> 00:02:39.480
the CPU she's flying how is this allowed I don't know but it's great because we

00:02:37.680 --> 00:02:43.720
kind of need this system for our next intrusive thought inside this

00:02:41.720 --> 00:02:49.280
environmental chamber is a liquid crystal display but just because they're

00:02:46.440 --> 00:02:53.959
liquid at room temperature doesn't mean that they are always liquid they can

00:02:51.599 --> 00:02:59.920
freeze what is the rated temperature of this monitor it doesn't say but most are

00:02:56.440 --> 00:03:01.800
rated to 0° while in operation andus 20

00:02:59.920 --> 00:03:07.959
while in storage so that seems like a sensible starting point this is so gross

00:03:05.360 --> 00:03:13.000
it feels worse than even just the motion blur like it almost feels like it leaves

00:03:10.440 --> 00:03:16.599
an imprint of the starting frame on my eye before anything even starts moving

00:03:14.879 --> 00:03:20.959
at all it it's like you're permanently recovering from a flashbang yeah it's

00:03:19.400 --> 00:03:26.440
like that exact effect it reminds me of a flashbang where it leaves that previous

00:03:24.560 --> 00:03:30.599
image imprinted that's what I was looking for my question now is what

00:03:28.840 --> 00:03:34.360
happens if we goow lower there's no water in the display so we don't need to

00:03:32.280 --> 00:03:40.239
worry about the liquid expanding as it freezes and breaking the monitor so

00:03:37.840 --> 00:03:44.080
uh it's starting to get to the point where this is so nauseating that it I

00:03:42.480 --> 00:03:48.400
need to look away from it for a minute but that's great because I need to talk

00:03:46.159 --> 00:03:52.680
about what's going on here it shouldn't be the crystals themselves freezing

00:03:50.599 --> 00:03:58.599
those should be good down to as low as -60 but what does happen is they start

00:03:55.720 --> 00:04:02.760
to gel up which increases the resistance that the display interface needs to

00:04:00.120 --> 00:04:07.760
overcome in order to twist them so what we're looking at here is the most

00:04:04.480 --> 00:04:09.680
extreme example of how pixel response

00:04:07.760 --> 00:04:14.519
times affect the gaming experience because both of these displays are

00:04:11.959 --> 00:04:18.959
running at 60 refreshes per second it's just that the pixels take so long to

00:04:16.600 --> 00:04:23.720
reach the new state we end up with this blurry flash bangy drunk goggles image

00:04:22.880 --> 00:04:30.360
oh man I don't know if we're going to make it to minus 400 this is damn near

00:04:27.680 --> 00:04:36.320
unplayable you see that just like with a flashbang I almost had yeah who who who

00:04:33.400 --> 00:04:40.639
who it looks like it's kind of changing in the background a little bit on some

00:04:38.360 --> 00:04:46.360
parts of the display oh did you see that the very top of the display is still

00:04:42.479 --> 00:04:48.039
refreshing but the rest isn't so again

00:04:46.360 --> 00:04:51.400
what we're seeing is the way a screen refreshes is typically from top to

00:04:49.479 --> 00:04:55.960
bottom so it's going like okay here's a new here's a

00:04:53.759 --> 00:05:01.160
new oh here we go this is really interesting too now we can see that the

00:04:58.440 --> 00:05:06.720
red pixels are or sub pixels rather seem to be having the hardest time twisting

00:05:03.520 --> 00:05:10.080
so maybe their viscosity is higher as

00:05:06.720 --> 00:05:11.479
temperatures go down we're only at - 32

00:05:10.080 --> 00:05:16.120
right now I really don't think we're going to make it to- 40 I think she's

00:05:13.440 --> 00:05:22.039
done bud can she even get a static image up there it's kind of starting to kind

00:05:18.840 --> 00:05:23.880
of do something I think it's fair to say

00:05:22.039 --> 00:05:30.280
she didn't make it to - 40 come on out little buddy sorry about

00:05:27.800 --> 00:05:34.280
that oh hey look at that she only had to get a little bit warmer

00:05:32.280 --> 00:05:38.160
on the very front for it to be able to display an image again I got to get this

00:05:35.880 --> 00:05:42.560
unplugged before she gets Frosty though good job buddy here's a fun one you've

00:05:40.720 --> 00:05:47.479
probably heard about solar flares and how dangerous they can be for computer

00:05:44.440 --> 00:05:50.440
systems here on Earth and well we don't

00:05:47.479 --> 00:05:55.720
have a sun but what we do have is a CT scanner from Luma field that we can use

00:05:52.759 --> 00:06:01.960
to blast Cosmic like X-rays at stuff like hey this computer all we got to do

00:05:58.759 --> 00:06:04.520
is close our up and configure a couple

00:06:01.960 --> 00:06:09.639
of things while lus is working on that I have some dark urges of my own while

00:06:07.880 --> 00:06:14.160
everyone knows that you should eject your USB before you pull it out so that

00:06:12.280 --> 00:06:19.039
you don't corrupt your files what would happen if I pulled out maybe the whole

00:06:16.680 --> 00:06:23.360
SSD we're currently playing valheim and it's installed on this drive right here

00:06:22.280 --> 00:06:27.440
we're walking around the world look at all that what would happen if I

00:06:27.759 --> 00:06:34.039
just look at that we're still playing the game now when you're using your

00:06:32.319 --> 00:06:37.240
computer the stuff that you're actively using is going to be sitting in RAM so

00:06:35.759 --> 00:06:41.560
we should be fine for now we can look around we can jump we can punch stuff

00:06:39.479 --> 00:06:45.680
like we're still playing the game but the moment that we have to load

00:06:48.440 --> 00:06:53.319
something it goes away but you see

00:06:51.800 --> 00:06:58.879
Windows is still running because we haven't removed our boot drive so what

00:06:56.240 --> 00:07:03.639
would happen if we did that look at that it's crazy it's it still works that's

00:07:01.319 --> 00:07:06.560
because Windows is mostly running in RAM right now you can actually get entire

00:07:05.280 --> 00:07:10.400
operating systems that will run exclusively in RAM but this isn't one of

00:07:08.840 --> 00:07:15.080
them and you'll see that when we say try to look at file

00:07:12.319 --> 00:07:19.639
explorer look at file look at there could be some very

00:07:18.120 --> 00:07:25.000
important information traveling between the SSD and your RAM and it could end up

00:07:22.639 --> 00:07:28.840
causing severe harm to your system you're probably going to be okay but hey

00:07:27.319 --> 00:07:32.560
why are you tempting fate that's what we're doing we tempted and it's for

00:07:30.800 --> 00:07:38.879
those very reasons that you probably expect that when we pull out our

00:07:34.960 --> 00:07:40.520
RAM it shuts down immediately ooh spicy

00:07:38.879 --> 00:07:45.240
this is what I mean you don't know what you're going to screw up and now we're in a repair mode let's hope that it

00:07:43.240 --> 00:07:48.280
doesn't slow us down too much obviously taking RAM out is going to be a problem

00:07:46.960 --> 00:07:54.759
but what would happen if we just you know put RAM in I'm I'm so surprised I thought that

00:07:52.319 --> 00:07:57.199
we would plug it in it would trip voltage monitor or something there' like

00:07:56.280 --> 00:08:02.639
be a ShortCircuit because of the connecting of the pins and whatever we don't have 16 GB of RAM right now we're

00:08:01.120 --> 00:08:07.879
still stuck as if we were running off of the single dim what if can I take this

00:08:05.520 --> 00:08:12.120
one out now hey maybe that was a fluke let's try

00:08:10.039 --> 00:08:17.080
this a second time you still get the RGB we've seen

00:08:15.479 --> 00:08:21.639
some crashes and stuff but I just feel like we haven't actually done any damage

00:08:19.720 --> 00:08:28.319
what if we delete system 32 and delete it's that easy except for

00:08:25.840 --> 00:08:34.200
it isn't Windows actually doesn't want you to break your own PC and so it asks

00:08:31.360 --> 00:08:38.080
for trusted installer permission to delete the folder and it won't let you

00:08:36.519 --> 00:08:42.440
get any further from this even if you're an administrator it doesn't matter but I

00:08:40.039 --> 00:08:48.000
know of a tool the command line that will let us do anything we want watch as

00:08:44.839 --> 00:08:48.000
I in one simple

00:08:50.160 --> 00:08:54.519
command as and then when I also say yes

00:08:53.160 --> 00:08:59.680
to all it's a lot of red unauthorized

00:08:57.240 --> 00:09:03.040
access exception why can't I I have a computer that just listens to what I

00:09:01.320 --> 00:09:05.839
tell it to do I think I know a guy who knows about computers and making them do

00:09:04.600 --> 00:09:11.800
what he wants it's Jordan ah yes the command

00:09:09.160 --> 00:09:17.000
line one final reminder before we do this don't deleting system 32 will harm

00:09:15.560 --> 00:09:21.800
your computer if you understand this warning hit the like button to proceed

00:09:19.360 --> 00:09:24.350
just down there all right open up the command line as an administrator and

00:09:23.680 --> 00:09:31.200
type this in congratulations you now own all the

00:09:28.440 --> 00:09:34.880
folders in system 32 you've massively compromised the security and the

00:09:32.839 --> 00:09:39.600
functionality of your PC but we're not done yet let's confirm this kill use

00:09:37.480 --> 00:09:44.839
this next command to change your Access Control level and now we just delete

00:09:42.600 --> 00:09:44.839
system

00:09:46.600 --> 00:09:51.120
32 okay so we removed a lot of files but

00:09:49.720 --> 00:09:56.440
why is Windows still working what if we try like doing something well you've

00:09:54.160 --> 00:10:01.399
angered it this is all your fault control shift Escape control delete oh

00:09:59.440 --> 00:10:06.360
failure to display security and I've never seen that before me neither I like

00:10:03.200 --> 00:10:09.240
the just X just X do you want to try

00:10:06.360 --> 00:10:13.680
rebooting it yeah okay automatic repair oh my it's so bored it can't do anything

00:10:11.519 --> 00:10:16.959
it's booting into here that implies that the recovery files were in system

00:10:17.600 --> 00:10:25.160
32 I think this computer's sufficiently borked okay um my work here is done yes

00:10:23.399 --> 00:10:31.320
you've done a wonderful job now it's my turn Adam's making me do this it'll be

00:10:28.519 --> 00:10:31.320
fun

00:10:32.040 --> 00:10:37.519
yeah don't worry it's l free yeah this

00:10:35.480 --> 00:10:43.880
isn't as satisfying as I had hoped not only is it not fun it's a waste of

00:10:40.360 --> 00:10:46.560
solder yeah really is let's do something

00:10:43.880 --> 00:10:50.959
slightly less stupid PC fans at their core are basically just an electric

00:10:48.720 --> 00:10:55.160
motor you apply some power to it it spins your fan but if you are the one

00:10:53.480 --> 00:10:59.320
that spins it suddenly your electric motor becomes an electric generator

00:10:57.600 --> 00:11:04.560
let's test it here we have a multimeter connected to a fan a tachometer and some

00:11:02.079 --> 00:11:04.560
compressed

00:11:05.320 --> 00:11:11.600
air now let's spin it and kill the motherboard given that we only saw like

00:11:09.160 --> 00:11:15.000
6 volts on the multimeter here when we spun this fan up I think the

00:11:13.560 --> 00:11:18.839
motherboard's going to be fine these are 12vt fans the header can probably handle

00:11:17.160 --> 00:11:22.800
12 volts here's the graph of our fan speed it's currently spinning at 2,000

00:11:20.600 --> 00:11:29.519
RPM and if we just give it a little bit of encouragement

00:11:24.480 --> 00:11:31.360
here there we go look at that

00:11:29.519 --> 00:11:36.000
we need the graph to go higher all right we're at a 7500

00:11:36.000 --> 00:11:45.480
RPM whatever reason it think it's going 1,000 RPM now that is not

00:11:41.680 --> 00:11:47.920
correct huh it's fine it's totally fine

00:11:45.480 --> 00:11:54.760
the RPMs for whatever reason went down to like 900 RPM when it was going over

00:11:52.200 --> 00:11:58.519
7,000 but I'm guessing that's just the math getting screw when it goes way

00:11:57.040 --> 00:12:02.639
faster than expected but according to this it went up to 7 7600 RPM and she's

00:12:00.920 --> 00:12:06.399
totally fine I don't think you have to worry about this too much but you know

00:12:04.120 --> 00:12:11.240
what you definitely have to worry about water I don't know why I said it like

00:12:08.440 --> 00:12:16.600
that water technically water doesn't damage your computer pure water isn't

00:12:13.600 --> 00:12:18.000
conductive it's what's disolved inside

00:12:16.600 --> 00:12:23.279
the water that counts this isn't pure water though so

00:12:20.639 --> 00:12:26.160
this is probably pretty bad so Adam's currently playing crisis and he's just

00:12:24.800 --> 00:12:29.839
going to keep playing until this computer stops working is it still going

00:12:28.440 --> 00:12:34.600
it's going fine yeah we're doing totally fine see spraying water on computers

00:12:32.160 --> 00:12:40.160
again can be fine until that shoo builds up unfortunately everything's got shoo

00:12:37.600 --> 00:12:45.760
in it so at some point this will give out is it still going

00:12:42.639 --> 00:12:47.800
no oh game over would you like me to

00:12:45.760 --> 00:12:52.560
keep going yeah I think we should stop okay the fans are still spinning the

00:12:50.120 --> 00:12:56.290
power supply has not tripped yeah despite you spraying directly into the

00:12:54.040 --> 00:12:58.120
back of

00:12:58.120 --> 00:13:07.320
it why is there thermal paste all over the CPU yeah the Linus 5 hours later

00:13:05.279 --> 00:13:10.839
we're coming back to our system that we put inside the Luma field and am I

00:13:09.560 --> 00:13:15.639
expecting there to be anything wrong with it it didn't even so much as crash

00:13:13.320 --> 00:13:19.040
well here's the thing this blasts x-rays which I don't know if you've ever been
