1
00:00:00,000 --> 00:00:04,000
You ever see those videos with thermal goop all over the CPU socket,

2
00:00:04,000 --> 00:00:07,000
or people jamming things into high-powered fans and thought,

3
00:00:07,000 --> 00:00:10,000
hmm, what would happen if I did that to my PC?

4
00:00:10,000 --> 00:00:15,000
Well, that's bad. First of all, you could get hurt. Or worse, you could damage your computer.

5
00:00:15,000 --> 00:00:18,000
So instead of risking it, let us indulge your intrusive thoughts.

6
00:00:18,000 --> 00:00:21,000
Like, what would happen if you used your monitor in the Arctic?

7
00:00:21,000 --> 00:00:25,000
Can liquid crystals freeze? We're about to try all of this and more,

8
00:00:25,000 --> 00:00:29,000
but, my friends, heed this warning. Do not try this at home.

9
00:00:29,000 --> 00:00:32,000
Instead, try this segle to our sponsor.

10
00:00:43,000 --> 00:00:49,000
In theory, modern high-quality pastes are both non-conductive and non-capacitive.

11
00:00:49,000 --> 00:00:52,000
So, this might work?

12
00:00:52,000 --> 00:00:56,000
Okay, but even if it's non-conductive, wouldn't that block the pads from touching?

13
00:00:56,000 --> 00:01:01,000
My theory is that the mounting pressure is going to be so high

14
00:01:01,000 --> 00:01:04,000
that it's going to kind of mash it out, kind of like when you mount a heat sink.

15
00:01:04,000 --> 00:01:07,000
It's not mashing out as much as I might have hoped,

16
00:01:07,000 --> 00:01:10,000
but there's a lot of mounting pressure on the CPU,

17
00:01:10,000 --> 00:01:13,000
and these are older, larger pins.

18
00:01:13,000 --> 00:01:16,000
And guys, this was already a motherboard that was a little bit flaky.

19
00:01:16,000 --> 00:01:20,000
Don't worry, we don't want to sacrifice something that works perfectly.

20
00:01:20,000 --> 00:01:23,000
Works enough to find out if it works, though.

21
00:01:23,000 --> 00:01:26,000
Shut up. No way.

22
00:01:27,000 --> 00:01:29,000
Clearly, we haven't put enough thermal paste in.

23
00:01:31,000 --> 00:01:39,000
For round two, we're bringing out the big guns. All right, that should be enough that she's going to squeeze out like toothpaste or peanut butter.

24
00:01:42,000 --> 00:01:45,000
No! This is crazy!

25
00:01:47,000 --> 00:01:51,000
Okay, I think this is our final stage here.

26
00:01:53,000 --> 00:02:00,000
Our ratio of thermal paste under the CPU to thermal paste on top of the CPU is extremely high.

27
00:02:00,000 --> 00:02:03,000
So we should probably get some more paste on top.

28
00:02:03,000 --> 00:02:08,000
Yeah, that's good, that's good. You know you've always wanted to try it. No!

29
00:02:08,000 --> 00:02:11,000
What if we run something like actually CPU intensive like Cinebench or something?

30
00:02:11,000 --> 00:02:16,000
Sure, I can do that. 62 degrees on the CPU. She's flying.

31
00:02:16,000 --> 00:02:22,000
How is this allowed? I don't know, but it's great because we kind of need this system for our next intrusive thought.

32
00:02:22,000 --> 00:02:26,000
Inside this environmental chamber is a liquid crystal display,

33
00:02:26,000 --> 00:02:33,000
but just because they're liquid at room temperature doesn't mean that they are always liquid.

34
00:02:33,000 --> 00:02:36,000
They can freeze. What is the rated temperature of this monitor?

35
00:02:36,000 --> 00:02:42,000
It doesn't say, but most are rated to zero degrees while in operation and minus 20 while in storage.

36
00:02:42,000 --> 00:02:45,000
So that seems like a sensible starting point.

37
00:02:45,000 --> 00:02:50,000
This is so gross. It feels worse than even just the motion blur.

38
00:02:50,000 --> 00:02:55,000
Like it almost feels like it leaves an imprint of the starting frame on my eye

39
00:02:55,000 --> 00:03:00,000
before anything even starts moving at all. It's like you're permanently recovering from a flashbang.

40
00:03:00,000 --> 00:03:07,000
Yeah, it reminds me of a flashbang where it leaves that previous image imprinted.

41
00:03:07,000 --> 00:03:12,000
That's what I was looking for. My question now is what happens if we go lower?

42
00:03:12,000 --> 00:03:15,000
There's no water in the display, so we don't need to worry about the liquid

43
00:03:15,000 --> 00:03:18,000
expanding as it freezes and breaking the monitor.

44
00:03:18,000 --> 00:03:24,000
So it's starting to get to the point where this is so nauseating

45
00:03:24,000 --> 00:03:29,000
that I need to look away from it for a minute, but that's great because I need to talk about what's going on here.

46
00:03:29,000 --> 00:03:32,000
It shouldn't be the crystals themselves freezing.

47
00:03:32,000 --> 00:03:35,000
Those should be good down to as low as minus 60,

48
00:03:35,000 --> 00:03:38,000
but what does happen is they start to gel up,

49
00:03:38,000 --> 00:03:44,000
which increases the resistance that the display interface needs to overcome in order to twist them.

50
00:03:44,000 --> 00:03:47,000
So what we're looking at here is the most extreme example

51
00:03:47,000 --> 00:03:51,000
of how pixel response times affect the gaming experience

52
00:03:51,000 --> 00:03:56,000
because both of these displays are running at 60 refreshes per second.

53
00:03:56,000 --> 00:03:59,000
It's just that the pixels take so long to reach the new state,

54
00:03:59,000 --> 00:04:04,000
we end up with this blurry, flashbang-y, drunk, goggles-y image.

55
00:04:04,000 --> 00:04:08,000
Oh man, I don't know if we're going to make it to minus 40.

56
00:04:08,000 --> 00:04:11,000
This is damn near unplayable. You see that?

57
00:04:11,000 --> 00:04:14,000
Just like with a flashbang, I almost had...

58
00:04:14,000 --> 00:04:21,000
Yeah! It looks like it's kind of changing in the background a little bit on some parts of the display.

59
00:04:21,000 --> 00:04:25,000
Oh, did you see that? The very top of the display is still refreshing,

60
00:04:25,000 --> 00:04:31,000
but the rest isn't. So again, what we're seeing is the way a screen refreshes is typically from top to bottom,

61
00:04:31,000 --> 00:04:34,000
so it's going like, okay, here's a new fr...

62
00:04:34,000 --> 00:04:39,000
Here's a new fr... Oh, here we go. This is really interesting too.

63
00:04:39,000 --> 00:04:43,000
Now we can see that the red pixels, or sub-pixels rather,

64
00:04:43,000 --> 00:04:46,000
seem to be having the hardest time twisting,

65
00:04:46,000 --> 00:04:50,000
so maybe their viscosity is higher as temperatures go down.

66
00:04:50,000 --> 00:04:53,000
We're only at minus 32 right now.

67
00:04:53,000 --> 00:04:56,000
I really don't think we're going to make it to minus 40. I think she's done, bud.

68
00:04:56,000 --> 00:04:59,000
Can she even get a static image up there?

69
00:04:59,000 --> 00:05:03,000
It's kind of starting to kind of do something.

70
00:05:03,000 --> 00:05:07,000
I think it's fair to say she didn't make it to minus 40.

71
00:05:07,000 --> 00:05:10,000
Come on out, little buddy. Sorry about that.

72
00:05:10,000 --> 00:05:15,000
Oh, hey, look at that! She only had to get a little bit warmer on the very front

73
00:05:15,000 --> 00:05:20,000
for it to be able to display an image again. I got to get the sun plugged before she gets frosty, though.

74
00:05:20,000 --> 00:05:24,000
Good job, buddy. Here's a fun one. You've probably heard about solar flares

75
00:05:24,000 --> 00:05:27,000
and how dangerous they can be for computer systems here on Earth,

76
00:05:27,000 --> 00:05:30,000
and, well, we don't have a sun,

77
00:05:30,000 --> 00:05:33,000
but what we do have is a CT scanner from Lumafield

78
00:05:33,000 --> 00:05:37,000
that we can use to blast cosmic-like x-rays at stuff like,

79
00:05:37,000 --> 00:05:42,000
hey, this computer. All we got to do is close her up

80
00:05:42,000 --> 00:05:46,000
and configure a couple of things. While Linus is working on that,

81
00:05:46,000 --> 00:05:49,000
I have some dark urges of my own.

82
00:05:49,000 --> 00:05:52,000
While everyone knows that you should eject your USB

83
00:05:52,000 --> 00:05:55,000
before you pull it out so that you don't corrupt your files,

84
00:05:55,000 --> 00:05:59,000
what would happen if I pulled out maybe the whole SSD?

85
00:05:59,000 --> 00:06:04,000
We're currently playing Valheim, and it's installed on this drive right here.

86
00:06:04,000 --> 00:06:08,000
We're walking around the world. Look at all that. What would happen if I just...

87
00:06:10,000 --> 00:06:13,000
And look at that. We're still playing the game.

88
00:06:13,000 --> 00:06:17,000
Now, when you're using your computer, the stuff that you're actively using is going to be sitting in RAM.

89
00:06:17,000 --> 00:06:20,000
So we should be fine for now. We can look around.

90
00:06:20,000 --> 00:06:23,000
We can jump. We can punch stuff. Like, we're still playing the game,

91
00:06:23,000 --> 00:06:26,000
but the moment that we have to load something...

92
00:06:31,000 --> 00:06:35,000
It goes away. But, you see, Windows is still running

93
00:06:35,000 --> 00:06:40,000
because we haven't removed our boot drive. So what would happen if we did that?

94
00:06:40,000 --> 00:06:43,000
Look at that. It's crazy. It still works.

95
00:06:43,000 --> 00:06:46,000
That's because Windows is mostly running in RAM right now.

96
00:06:46,000 --> 00:06:50,000
You can actually get entire operating systems that will run exclusively in RAM,

97
00:06:50,000 --> 00:06:54,000
but this isn't one of them, and you'll see that when we say try to look at File Explorer...

98
00:06:55,000 --> 00:06:56,000
Look at File...

99
00:06:58,000 --> 00:07:01,000
Look at... There could be some very important information

100
00:07:01,000 --> 00:07:06,000
traveling between the SSD and your RAM, and it could end up causing severe harm to your system.

101
00:07:06,000 --> 00:07:10,000
You're probably going to be okay, but hey, why are you tempted in fate?

102
00:07:10,000 --> 00:07:15,000
That's what we're doing. We tempted. And it's for those very reasons that you probably expect

103
00:07:15,000 --> 00:07:19,000
that when we pull out our RAM, it shuts down immediately.

104
00:07:19,000 --> 00:07:23,000
Ooh, spicy. This is what I mean. You don't know what you're going to screw up,

105
00:07:23,000 --> 00:07:26,000
and now we're in a repair mode. Let's hope that it doesn't slow us down too much.

106
00:07:26,000 --> 00:07:31,000
Obviously, taking RAM out is going to be a problem, but what would happen if we just, you know, put RAM in?

107
00:07:32,000 --> 00:07:35,000
I'm so surprised. I thought that we would plug it in.

108
00:07:35,000 --> 00:07:38,000
It would chip voltage monitor or something. There would be a ShortCircuit

109
00:07:38,000 --> 00:07:42,000
because of the connecting of the pins and whatever. We don't have 16 gigabytes of RAM right now.

110
00:07:42,000 --> 00:07:46,000
We're still stuck as if we were running off of the single dim.

111
00:07:46,000 --> 00:07:49,000
What if I can take this one out now? Hey.

112
00:07:50,000 --> 00:07:53,000
Maybe that was a fluke. Let's try this a second time.

113
00:07:54,000 --> 00:07:58,000
You still got the RGB? We've seen some crashes and stuff,

114
00:07:58,000 --> 00:08:01,000
but I just feel like we haven't actually done any damage.

115
00:08:01,000 --> 00:08:03,000
What if we delete system 32?

116
00:08:04,000 --> 00:08:07,000
And delete. It's that easy.

117
00:08:07,000 --> 00:08:11,000
Except for it isn't. Windows actually doesn't want you to break your own PC,

118
00:08:11,000 --> 00:08:15,000
and so it asks for trusted installer permission

119
00:08:15,000 --> 00:08:19,000
to delete the folder, and it won't let you get any further from this.

120
00:08:19,000 --> 00:08:22,000
Even if you're an administrator, it doesn't matter. But I know of a tool.

121
00:08:22,000 --> 00:08:25,000
The command line that will let us do anything we want.

122
00:08:25,000 --> 00:08:28,000
Watch. As I in one simple command.

123
00:08:32,000 --> 00:08:35,000
And then when I also say yes to all.

124
00:08:37,000 --> 00:08:40,000
It's a lot of red. Unauthorized access exception.

125
00:08:40,000 --> 00:08:43,000
Why can't I have a computer that just listens to what I tell it to do?

126
00:08:43,000 --> 00:08:47,000
I think I know a guy who knows about computers and making them do what he wants.

127
00:08:48,000 --> 00:08:51,000
It's Jordan. Ah, yes. The command line.

128
00:08:51,000 --> 00:08:54,000
One final reminder before we do this.

129
00:08:54,000 --> 00:08:58,000
Don't. Deleting system 32 will harm your computer.

130
00:08:58,000 --> 00:09:01,000
If you understand this warning, hit the like button to proceed.

131
00:09:01,000 --> 00:09:06,000
Just down there. Alright. Open up the command line as an administrator and type this in.

132
00:09:08,000 --> 00:09:12,000
Congratulations. You now own all the folders in system 32.

133
00:09:12,000 --> 00:09:16,000
You've massively compromised the security and the functionality of your PC.

134
00:09:16,000 --> 00:09:19,000
But we're not done yet. Let's confirm this kill.

135
00:09:19,000 --> 00:09:22,000
Use this next command to change your access control level.

136
00:09:23,000 --> 00:09:25,000
And now, you just delete system 32.

137
00:09:29,000 --> 00:09:33,000
Okay, so we removed a lot of files. But why is Windows still working?

138
00:09:33,000 --> 00:09:36,000
What if we try, like, doing something? Whoa.

139
00:09:36,000 --> 00:09:39,000
You've angered it. This is all your fault. Controls are to escape.

140
00:09:39,000 --> 00:09:43,000
Controls are to delete. Failure to display security.

141
00:09:43,000 --> 00:09:46,000
I've never seen that before. Me neither. I like that just X.

142
00:09:46,000 --> 00:09:49,000
Just X. Do you want to try rebooting it?

143
00:09:49,000 --> 00:09:52,000
Yeah, okay. Automatic repair. Oh, my.

144
00:09:52,000 --> 00:09:55,000
It's so borked. It can't do anything. It's booting into here.

145
00:09:55,000 --> 00:09:58,000
That implies that the recovery files were in system 32.

146
00:10:00,000 --> 00:10:03,000
I think this computer is sufficiently borked. Okay.

147
00:10:03,000 --> 00:10:06,000
My work here is done. Yes, you've done a wonderful job.

148
00:10:06,000 --> 00:10:09,000
Now it's my turn. Adam's making me do this.

149
00:10:10,000 --> 00:10:11,000
It'll be fun.

150
00:10:15,000 --> 00:10:19,000
Don't worry, it's life-free. Yeah, this isn't as satisfying as I'd hoped.

151
00:10:19,000 --> 00:10:23,000
Not only is it not fun, it's a waste of solder.

152
00:10:23,000 --> 00:10:27,000
Yeah, really is. Let's do something slightly less stupid.

153
00:10:27,000 --> 00:10:31,000
PC fans at their core are basically just an electric motor.

154
00:10:31,000 --> 00:10:34,000
You apply some power to it, it spins your fan.

155
00:10:34,000 --> 00:10:39,000
But if you are the one that spins it, suddenly your electric motor becomes an electric generator.

156
00:10:39,000 --> 00:10:42,000
Let's test it. Here we have a multimeter connected to a fan,

157
00:10:42,000 --> 00:10:45,000
a tachometer, and some compressed air.

158
00:10:45,000 --> 00:10:49,000
Now let's spin it and kill the motherboard.

159
00:10:49,000 --> 00:10:53,000
Given that we only saw like 6 volts on the multimeter here

160
00:10:53,000 --> 00:10:56,000
when we spun this fan up, I think the motherboard is going to be fine.

161
00:10:56,000 --> 00:10:59,000
These are 12 volt fans. The header can probably handle 12 volts.

162
00:10:59,000 --> 00:11:03,000
Here's the graph of our fan speed. It's currently spinning at 2,000 RPM.

163
00:11:03,000 --> 00:11:06,000
And if we just give it a little bit of encouragement here.

164
00:11:07,000 --> 00:11:09,000
There we go. Look at that.

165
00:11:11,000 --> 00:11:13,000
We need the graph to go higher.

166
00:11:14,000 --> 00:11:16,000
All right, we're at a 7,500 RPM.

167
00:11:19,000 --> 00:11:22,000
For whatever reason, I think it's going 1,000 RPM now. That is not correct.

168
00:11:25,000 --> 00:11:32,000
It's fine. It's totally fine. The RPMs for whatever reason went down to like 900 RPM

169
00:11:32,000 --> 00:11:37,000
when it was going over 7,000. But I'm guessing that's just the math getting screwed

170
00:11:37,000 --> 00:11:42,000
when it goes way faster than expected. But according to this, it went up to 7,600 RPM

171
00:11:42,000 --> 00:11:46,000
and she's totally fine. I don't think you have to worry about this too much.

172
00:11:46,000 --> 00:11:49,000
But you definitely have to worry about water.

173
00:11:49,000 --> 00:11:52,000
I don't know why I said it like that. Water.

174
00:11:52,000 --> 00:11:56,000
Technically, water doesn't damage your computer. Pure water isn't conductive.

175
00:11:56,000 --> 00:12:00,000
It's what's dissolved inside the water that counts.

176
00:12:00,000 --> 00:12:04,000
This isn't pure water though. So this is probably pretty bad.

177
00:12:04,000 --> 00:12:07,000
So Adam's currently playing crisis and he's just going to keep playing

178
00:12:07,000 --> 00:12:10,000
until this computer stops working. Is it still going?

179
00:12:10,000 --> 00:12:14,000
It's going fine. Yeah, we're doing totally fine. See, spraying water on computers again

180
00:12:14,000 --> 00:12:17,000
can be fine until that schmoo builds up.

181
00:12:17,000 --> 00:12:20,000
Unfortunately, everything's got schmoo in it.

182
00:12:20,000 --> 00:12:23,000
So at some point, this will give out.

183
00:12:23,000 --> 00:12:26,000
Is it still going? No. Oh.

184
00:12:26,000 --> 00:12:29,000
Game over. Would you like me to keep going? Yeah, I think we should stop.

185
00:12:29,000 --> 00:12:32,000
Okay. The fans are still spinning.

186
00:12:32,000 --> 00:12:35,000
The power supply has not tripped. Yeah.

187
00:12:35,000 --> 00:12:41,000
Despite you spraying directly into the back of it. Bzz, bzz.

188
00:12:41,000 --> 00:12:44,000
Why is there thermal paste all over the CPU?

189
00:12:44,000 --> 00:12:49,000
Linus. Five hours later, we're coming back to our system

190
00:12:49,000 --> 00:12:53,000
that we put inside the Luma field and am I expecting there to be anything wrong with it?

191
00:12:53,000 --> 00:12:56,000
It didn't even so much as crash. Well, here's the thing.

192
00:12:56,000 --> 00:12:59,000
This blasts X-rays, which I don't know if you've ever been to an airport,

193
00:12:59,000 --> 00:13:02,000
but your laptop goes through an X-ray reader

194
00:13:02,000 --> 00:13:07,000
every time you go on there. Sure. If your laptop isn't a, you know, analog film camera,

195
00:13:07,000 --> 00:13:10,000
then it's probably not going to have an issue with that.

196
00:13:10,000 --> 00:13:15,000
Yeah. At first, Luma field does publish guidelines

197
00:13:15,000 --> 00:13:19,000
for how long is safe to expose electronics to their machine.

198
00:13:19,000 --> 00:13:23,000
And they're pretty long and they're probably padding the estimates.

199
00:13:23,000 --> 00:13:26,000
Yeah. And even if we were trying to guarantee

200
00:13:26,000 --> 00:13:29,000
that something went wrong with this, who knows if it would actually affect something

201
00:13:29,000 --> 00:13:35,000
that matters on what we're doing on our system. We saw this actually when we tried to EMP blast

202
00:13:35,000 --> 00:13:39,000
literally the RAM chips on a laptop. We had to get like right in there.

203
00:13:39,000 --> 00:13:40,000
They're pretty resilient.

204
00:13:47,000 --> 00:13:50,000
So if you ever want to bring your laptop to your next CAT scan,

205
00:13:50,000 --> 00:13:53,000
you can totally do that. Tell the doctors that we said it was okay.

206
00:13:53,000 --> 00:13:56,000
Do you know what else is okay? A segue to our sponsor.

207
00:13:57,000 --> 00:14:00,000
If you guys enjoyed this video, maybe check out the one where we used

208
00:14:00,000 --> 00:14:05,000
the car radiator to cool a computer. It wasn't successful, but it kind of had the same energy.

209
00:14:05,000 --> 00:14:06,000
Great.
