1
00:00:00,719 --> 00:00:07,040
this right here is the phenomic hex 2.0

2
00:00:05,200 --> 00:00:11,519
CPU cooler and if you were to look at the

3
00:00:09,120 --> 00:00:16,240
performance claims alone you'd be forgiven for thinking there's some kind

4
00:00:13,440 --> 00:00:20,320
of magic going on here since it seems to be able to cool

5
00:00:18,000 --> 00:00:24,000
much better than its relatively small size would suggest

6
00:00:23,039 --> 00:00:31,519
but unfortunately for perpetual motion machine makers and this cooler alike

7
00:00:28,400 --> 00:00:33,520
magic is not real

8
00:00:31,519 --> 00:00:38,079
and thermodynamics is what makes this product special is of

9
00:00:35,520 --> 00:00:43,760
course its use of a peltier or thermoelectric cooler which uses

10
00:00:40,000 --> 00:00:46,160
electricity to move heat from one side

11
00:00:43,760 --> 00:00:49,440
of the device down here or up there wherever it is to the other

12
00:00:48,559 --> 00:00:54,079
pretty cool but what's even cooler

13
00:00:52,640 --> 00:00:59,199
is this what alex is holding is two aquarium

14
00:00:56,399 --> 00:01:05,199
coolers using a similar technology which together should be able to provide

15
00:01:01,640 --> 00:01:07,119
360 watts of cooling power so we're

16
00:01:05,199 --> 00:01:11,600
going to see how our two contraptions here manage against a 10 core

17
00:01:09,280 --> 00:01:15,520
overclocked processor in a new crazy cooling experiment series that we're

18
00:01:13,360 --> 00:01:20,040
calling bad cooling ideas

19
00:01:17,840 --> 00:01:24,040
yeah

20
00:01:25,040 --> 00:01:31,680
vincero watches is celebrating their five-year anniversary and everything on

21
00:01:29,040 --> 00:01:36,180
the website is on sale until august 18 2019. check them out at the link in the

22
00:01:33,840 --> 00:01:44,479
video description

23
00:01:44,479 --> 00:01:51,360
all right so tech cooling is pretty well established at this point but that

24
00:01:48,799 --> 00:01:56,079
doesn't prevent people from marketing it as basically magic check out this

25
00:01:53,759 --> 00:01:59,439
desktop cooler on kickstarter so

26
00:01:56,960 --> 00:02:04,560
the way apelche or tech works fundamentally is by having electrons in

27
00:02:02,159 --> 00:02:09,440
the form of dc current pass through two elements in one of the elements the

28
00:02:06,640 --> 00:02:14,480
electrons go from a low to a high energy state absorbing heat and in the other

29
00:02:12,239 --> 00:02:19,360
they go from a high to a low energy state releasing heat so you've got the

30
00:02:16,959 --> 00:02:24,560
cold side and the hot side with a maximum temperature difference of

31
00:02:21,360 --> 00:02:26,480
usually around 70 degrees celsius the

32
00:02:24,560 --> 00:02:32,480
cooling capabilities of a tech are directly proportional to the power

33
00:02:28,800 --> 00:02:34,560
consumption of the tech module so back

34
00:02:32,480 --> 00:02:39,040
to that kickstarter thing it's not magic at all and really annoyed me when i

35
00:02:36,400 --> 00:02:45,519
found it in my email so basically all it's doing is using the tech cooler to

36
00:02:42,560 --> 00:02:51,120
make the water in the back of it hotter so in the end instead of your room being

37
00:02:48,480 --> 00:02:54,400
cooler which like it does a bit you just end up with a container full of hot

38
00:02:53,440 --> 00:02:59,599
water it's branded as eco-friendly but it's

39
00:02:57,200 --> 00:03:05,720
using a tech cooler which are just not efficient at all so it's using heck tons

40
00:03:02,560 --> 00:03:09,440
of electricity and it costs

41
00:03:05,720 --> 00:03:10,720
350 dollars and it can only cool 60

42
00:03:09,440 --> 00:03:16,000
watts a similarly priced refrigerant based

43
00:03:12,879 --> 00:03:17,200
cooler has literally 50 times more

44
00:03:16,000 --> 00:03:20,400
cooling but it does have a bluetooth speaker

45
00:03:19,040 --> 00:03:24,319
which i don't think that's enough to save that my air conditioner doesn't have that

46
00:03:22,879 --> 00:03:27,840
so let's get this thing on the CPU wait a

47
00:03:26,879 --> 00:03:32,799
second they did what we tell everyone to do

48
00:03:30,159 --> 00:03:36,319
they just completely ripped off Noctua's mounting mechanism

49
00:03:34,480 --> 00:03:42,080
it's completely identical oh yeah yeah i saw that uh it's not

50
00:03:39,200 --> 00:03:44,959
quite identical it's like a bit worse yeah the back plate is like an

51
00:03:43,440 --> 00:03:49,760
all-in-one instead of having separate ones for AMD and Intel

52
00:03:46,959 --> 00:03:52,640
but yeah it's pretty solid yeah good for them

53
00:03:50,879 --> 00:03:59,360
at least they got one thing right so now that we know tech cooling is not in

54
00:03:56,239 --> 00:04:03,040
fact magic let's investigate this cooler

55
00:03:59,360 --> 00:04:05,200
a little bit more closely so phononic is

56
00:04:03,040 --> 00:04:11,040
not actually the first to attempt to build a peltier into a CPU heatsink

57
00:04:08,000 --> 00:04:14,720
monsoon coolant and swift tech all did

58
00:04:11,040 --> 00:04:16,639
it way back in 2007. and there may even

59
00:04:14,720 --> 00:04:22,800
be earlier instances why didn't it catch on i don't know

60
00:04:18,959 --> 00:04:25,360
maybe it just wasn't mature enough so uh

61
00:04:22,800 --> 00:04:31,199
let's take a closer look at this more recent attempt here

62
00:04:28,720 --> 00:04:35,040
how does this go in it just sits there uh yeah you need to put the

63
00:04:33,759 --> 00:04:38,400
like that or it doesn't really go back together no that's stupid

64
00:04:37,520 --> 00:04:46,320
all right and then this goes here and just kind of

65
00:04:43,919 --> 00:04:48,960
really let's squeeze this together i spent a fair bit of time figuring out

66
00:04:47,840 --> 00:04:53,600
how to get it back together while you were gone

67
00:04:50,880 --> 00:04:53,600
yeah hey

68
00:04:55,360 --> 00:05:01,680
does that screw it all the way down yeah does that mean is that mounting pressure so right oh

69
00:04:59,759 --> 00:05:06,560
you put it on upside down now the good news is that our uh

70
00:05:04,240 --> 00:05:11,039
contact looks great between the heatsink and CPU oh yeah so you've got

71
00:05:08,400 --> 00:05:16,080
pre-testing done on an nhu 12 va right yep now to be clear this is a much

72
00:05:13,840 --> 00:05:19,440
larger heat sink with almost twice as many heat pipes

73
00:05:18,560 --> 00:05:23,199
but it's 50 bucks cheaper so

74
00:05:21,680 --> 00:05:28,080
these things got to find a way to be competitive yeah

75
00:05:26,160 --> 00:05:32,720
you've got a second power supply just for our heatsink here

76
00:05:30,320 --> 00:05:37,120
yeah so if you were installing this in a regular computer you would do this

77
00:05:35,280 --> 00:05:40,479
we are just using a second power supply so we can find out just how much power

78
00:05:38,880 --> 00:05:44,560
this thing is drawing because of course for a tech to work you

79
00:05:42,639 --> 00:05:49,120
do need a power source for the palchie module itself which in the case of this

80
00:05:46,800 --> 00:05:54,080
cooler is embedded in the base between the heatsink fins and heat pipes up here

81
00:05:51,120 --> 00:05:57,039
and then another piece of copper now theoretically the bottom of this thing

82
00:05:55,600 --> 00:06:01,199
should be quite chilly it's hard to feel it though i don't know

83
00:05:59,680 --> 00:06:05,520
right now it's only drawing four watts so

84
00:06:02,960 --> 00:06:09,840
it might need some input from the fan header to really turn on

85
00:06:07,759 --> 00:06:14,560
interesting i'm having fun are you guys having fun

86
00:06:12,560 --> 00:06:18,160
this is probably the coolest thing hey

87
00:06:16,560 --> 00:06:22,160
i love that merch product placement was that you or david

88
00:06:20,639 --> 00:06:25,680
i don't know is that just andy's water bottle oh it could be

89
00:06:25,759 --> 00:06:29,440
uh yeah andy just left his water bottle

90
00:06:29,759 --> 00:06:34,360
we all have the same water bottle so like

91
00:06:35,280 --> 00:06:41,440
so we're just doing the good old blender bmw seeing what the max

92
00:06:39,440 --> 00:06:47,039
temperature is at the end of it we're idling at around 30 low

93
00:06:45,680 --> 00:06:51,520
30 maybe yeah cool 30 low to 30 min so what we're

94
00:06:49,759 --> 00:06:58,720
trying to beat is a maximum core temperature of 68 degrees and an overall

95
00:06:54,400 --> 00:07:00,400
average across all 10 cores of 64.9

96
00:06:58,720 --> 00:07:06,800
okay you think we're gonna think we're gonna do it no

97
00:07:02,960 --> 00:07:06,800
oh oh wrong window active

98
00:07:06,880 --> 00:07:09,440
here we go

99
00:07:10,240 --> 00:07:14,479
how's our power driver over there three watts right now

100
00:07:13,440 --> 00:07:19,120
14. 30 oh so it kicked in

101
00:07:19,199 --> 00:07:24,960
interesting so that's fairly sophisticated it keeps the

102
00:07:22,880 --> 00:07:29,599
tech idle unless there's an actual heat load which

103
00:07:27,440 --> 00:07:33,039
is really good because otherwise you would actually end up with your CPU

104
00:07:31,120 --> 00:07:38,800
reaching sub-ambient temperatures which could cause condensation and shorting

105
00:07:37,280 --> 00:07:42,160
yeah up to 40 watts 42 is the highest that i've

106
00:07:40,880 --> 00:07:46,000
seen one of my cores is at 65 already

107
00:07:45,199 --> 00:07:49,919
okay that's not too bad though okay we're

108
00:07:48,240 --> 00:07:55,680
almost done so our maximum core managed to reach 70

109
00:07:53,440 --> 00:08:01,199
degrees we've got another one at 69 another one at 68 68 67

110
00:07:59,520 --> 00:08:04,960
yeah i mean he's coming back with his trusty

111
00:08:03,039 --> 00:08:08,400
calculator but i think i've already determined that we're higher science

112
00:08:06,639 --> 00:08:12,400
says it's worse yep two and a half degrees worse yep bummer

113
00:08:10,800 --> 00:08:15,759
this situation could only get better though right should we turn on the overclock

114
00:08:14,800 --> 00:08:20,800
yes so one of the special things about techs

115
00:08:18,319 --> 00:08:26,400
is that from my understanding if you overwhelm them so you have like

116
00:08:25,039 --> 00:08:29,680
too much heat they actually eventually become an

117
00:08:28,240 --> 00:08:32,800
insulator i'm hoping that doesn't happen but uh

118
00:08:31,440 --> 00:08:36,080
what do our CPU temps look like now we're 104 right now

119
00:08:37,200 --> 00:08:44,880
106. hey it's trying hard yeah i wonder

120
00:08:41,839 --> 00:08:44,880
how it's looking there

121
00:08:45,920 --> 00:08:50,880
um i don't know if this is accurate because i don't know

122
00:08:49,360 --> 00:08:55,120
if it's just bouncing around but that looks like 50 degrees on top of the

123
00:08:53,440 --> 00:08:57,920
CPU there oh we're at a hunt oh

124
00:08:56,959 --> 00:09:01,839
it's it's hit the thermal max i'm guessing

125
00:09:00,080 --> 00:09:06,240
that it's down clock now oh it hasn't yet yeah it's down clocking now

126
00:09:03,680 --> 00:09:11,120
everything's at like 110 degrees um fortunately

127
00:09:07,680 --> 00:09:11,120
we always had a backup plan

128
00:09:11,279 --> 00:09:14,880
just shutting it down

129
00:09:14,880 --> 00:09:20,880
okay so while we were removing this this is

130
00:09:18,480 --> 00:09:24,959
absolutely fascinating now what i was expecting

131
00:09:22,399 --> 00:09:29,600
was for all of our heat sinks and heat pipes over here to be cooling the hot

132
00:09:27,279 --> 00:09:32,480
side of the tech but alex pointed out that it actually works a little bit

133
00:09:30,720 --> 00:09:36,800
differently than that yeah it looks like this entire side

134
00:09:34,800 --> 00:09:41,760
is just working like a regular air cooler and whatever's left over

135
00:09:39,519 --> 00:09:44,640
after those heat pipes is then being cooled

136
00:09:42,880 --> 00:09:49,040
by the tech which is putting all that heat into the other

137
00:09:46,240 --> 00:09:51,440
side right so our tech is actually sitting in between

138
00:09:50,560 --> 00:09:57,760
two quad heat pipe single tower coolers

139
00:09:54,959 --> 00:10:03,279
so effectively this one is cooling the hot side of our tech and this one is

140
00:10:00,399 --> 00:10:08,000
just cooling the CPU directly with the cold side of the tech also cooling this

141
00:10:05,920 --> 00:10:10,800
plate from right here in the middle yeah i feel like they were just concerned

142
00:10:09,120 --> 00:10:13,760
that your average CPU would overwhelm the tech which makes sense because it's

143
00:10:12,399 --> 00:10:17,120
only 40 watts right and

144
00:10:15,440 --> 00:10:22,720
that would explain why it didn't just completely blow up yeah

145
00:10:19,440 --> 00:10:25,360
and movie magic everything is different

146
00:10:22,720 --> 00:10:29,600
so we have a whole water cooling loop just on the table here 360 rad costs

147
00:10:27,680 --> 00:10:33,600
about the same as our two peltier units it's already been pre-tested we have a

148
00:10:30,959 --> 00:10:39,760
new overclock that pushes this to its limits nice and it's all tested uh so

149
00:10:37,839 --> 00:10:44,000
that's the same price as this which means that these two have to keep up

150
00:10:41,839 --> 00:10:49,040
with that correct and like the RGB is included in the price so yeah the first

151
00:10:46,720 --> 00:10:53,200
thing i notice about these is that while they are fairly pre-done as a solution

152
00:10:51,920 --> 00:10:58,480
for the user um they don't have connectors on them

153
00:10:57,200 --> 00:11:05,120
beautiful okay snip me like my doctor did it

154
00:11:02,800 --> 00:11:10,480
okay we need we need to rethink this everyone's just shocked that

155
00:11:07,600 --> 00:11:13,600
doing things the correct way is easier i'm shocked

156
00:11:12,000 --> 00:11:18,399
yeah this is you know after the crap you gave me about my soldering that is really not a lot better

157
00:11:16,560 --> 00:11:21,760
yeah it's not heating up the way that i would like it to want some electrical

158
00:11:20,480 --> 00:11:27,040
tape yep i mean once you wrap it in enough electrical tape no one can tell

159
00:11:25,200 --> 00:11:30,800
you're soldering job okay in all seriousness though guys yes

160
00:11:29,120 --> 00:11:36,160
this is really jank and no neither alex nor i would ever

161
00:11:33,440 --> 00:11:41,200
deploy something like this in like a 24 7 application but this will run for

162
00:11:39,120 --> 00:11:46,399
quite literally five to ten minutes and we have a fire extinguisher right there

163
00:11:44,079 --> 00:11:51,920
okay wow that immediately got really cold

164
00:11:49,519 --> 00:11:58,240
wow eighteen fifteen thirteen eleven that's absolutely

165
00:11:55,760 --> 00:12:04,640
that's really cold we're gonna be below zero very soon

166
00:12:00,800 --> 00:12:06,560
uh yep we're below zero degrees

167
00:12:04,640 --> 00:12:08,839
so this could be a bad idea to keep my finger on here yeah what's it like on

168
00:12:08,240 --> 00:12:15,200
the bottom uh 60 60 70 something like that not bad it

169
00:12:13,200 --> 00:12:19,040
feels fine so guys what we're looking at here is a much more powerful peltier

170
00:12:16,959 --> 00:12:22,160
module you can see it has just larger gauge wires going into it it does seem

171
00:12:20,800 --> 00:12:26,079
to be a bit bigger than the one that was built into the heatsink and what it's

172
00:12:24,079 --> 00:12:30,560
doing is it's got its hot side over here which is being cooled by this double

173
00:12:27,680 --> 00:12:34,399
tower cooler with 392 millimeter fans and then it's got its cold side over

174
00:12:32,399 --> 00:12:39,600
here with just this rudimentary water block that is really quite frosty you

175
00:12:37,279 --> 00:12:42,560
can actually see there's frost forming on it and i'm leaving fingerprints

176
00:12:40,959 --> 00:12:47,040
behind so that's going to chill our water and this is going to dissipate the

177
00:12:44,639 --> 00:12:52,240
heat of our peltier module and our CPU to the surrounding air also it's

178
00:12:48,720 --> 00:12:53,839
currently drawing 301 watts not bad yeah

179
00:12:52,240 --> 00:12:57,839
instead of necessarily trying to have it at the highest point and like minimize

180
00:12:55,680 --> 00:13:02,000
water loss that way what if we just

181
00:12:59,200 --> 00:13:05,519
cut the tube and then i just jam this on there

182
00:13:02,720 --> 00:13:09,120
um this is a quick connection sure okay so actually oh pinch it pinch it

183
00:13:08,000 --> 00:13:13,440
wait wait wait wait don't don't lift that up not too high this is not half

184
00:13:11,200 --> 00:13:16,800
inch tubing okay

185
00:13:14,720 --> 00:13:22,160
okay let's keep that oh wow

186
00:13:18,240 --> 00:13:24,959
that is not coming off so here's an idea

187
00:13:22,160 --> 00:13:28,959
yeah should we just get this out of here um

188
00:13:26,320 --> 00:13:34,240
what's attached okay now that looked really jank but

189
00:13:30,720 --> 00:13:37,200
that's how much water we lost

190
00:13:34,240 --> 00:13:37,200
yeah we're basically pros

191
00:13:38,079 --> 00:13:44,639
but that was intentional so how proud are we right now we

192
00:13:41,200 --> 00:13:46,079
basically invented a cool it boreous

193
00:13:44,639 --> 00:13:51,040
not very now our idle temps are looking pretty

194
00:13:48,160 --> 00:13:55,120
fine 26 27 27. so actually it is lower now it's 23. oh

195
00:13:54,240 --> 00:13:59,760
wow actually it's dropping really fast yeah

196
00:13:57,440 --> 00:14:04,240
our lowest core is at 22 already all right f12

197
00:14:01,440 --> 00:14:04,240
yep here it goes

198
00:14:04,480 --> 00:14:11,040
so we're looking at a maximum temperature of 84 to beat

199
00:14:08,320 --> 00:14:15,040
80.7 is our average on all cores remember there's two chillers in series

200
00:14:12,720 --> 00:14:19,839
here so we want this one versus this one so this one's like

201
00:14:17,600 --> 00:14:22,480
26. and this guy

202
00:14:23,279 --> 00:14:31,199
come on it's like

203
00:14:27,199 --> 00:14:33,040
it's like 26 also

204
00:14:31,199 --> 00:14:37,600
well it's trying they're trying there bud oh our render's

205
00:14:35,199 --> 00:14:43,680
done oh so our maximum on the hottest core was 80. however

206
00:14:41,199 --> 00:14:46,800
that doesn't tell the whole story because

207
00:14:44,399 --> 00:14:51,519
we actually started with our water chilled to sub-ambient

208
00:14:49,040 --> 00:14:55,199
and we could see as the test ran that it was definitely heating up so we need to

209
00:14:53,199 --> 00:15:00,639
do a longer test yeah so how'd we do

210
00:14:56,880 --> 00:15:03,680
oh yeah we had to beat 84 degrees

211
00:15:00,639 --> 00:15:06,000
and we hit what

212
00:15:03,680 --> 00:15:10,720
94 that's so that's not great so all that's

213
00:15:08,639 --> 00:15:14,639
left after of course zipping up my stealth hoodie and telling you guys it's

214
00:15:12,160 --> 00:15:18,240
available on lttstore.com is to walk through

215
00:15:16,240 --> 00:15:22,800
why this is a bad idea so there's a couple of things number one

216
00:15:20,000 --> 00:15:26,959
it actually isn't any more compact even though the peltier module itself is

217
00:15:24,880 --> 00:15:32,560
quite small because you've got to cool all that extra heat number two is the

218
00:15:29,519 --> 00:15:35,199
extra heat and therefore noise number

219
00:15:32,560 --> 00:15:40,000
three is the cost for the same price we were able to get this radiator along

220
00:15:37,199 --> 00:15:45,440
with like RGB fans and stuff and number four is of course the power consumption

221
00:15:42,800 --> 00:15:50,800
this at full blast consumes about 10 watts while this consumes about

222
00:15:48,759 --> 00:15:54,399
300 watts so the thing with tex is that yeah it's

223
00:15:52,399 --> 00:15:58,079
cool that you can reach sub-ambient temperatures as long as there's not much

224
00:15:55,839 --> 00:16:02,000
heat load but if as soon as you fire up something intensive like a render your

225
00:16:00,320 --> 00:16:06,000
temperatures go higher than just with a traditional water cooling radiator then

226
00:16:04,160 --> 00:16:10,480
that's kind of a bummer but guys make sure you're subscribed so you

227
00:16:08,639 --> 00:16:16,399
don't miss this video because that doesn't mean that peltiers are

228
00:16:13,040 --> 00:16:18,480
necessarily a bad idea the way that they

229
00:16:16,399 --> 00:16:23,199
were in this video now the way we used to do it in the old days was we'd take a

230
00:16:20,639 --> 00:16:28,240
peltier and put it directly between the CPU block and the CPU taking the cooling

231
00:16:26,399 --> 00:16:33,279
right where it's needed now the problem was that cpus outpaced peltiers in terms

232
00:16:31,680 --> 00:16:38,399
of how much heat they were outputting and what kind of peltiers you could get

233
00:16:35,120 --> 00:16:39,360
so it became just impractical but alex

234
00:16:38,399 --> 00:16:44,720
found oh yeah we found one that's 545 watts

235
00:16:42,480 --> 00:16:49,279
and draws 32 amps so that's on its way from ebay that's

236
00:16:46,720 --> 00:16:53,279
going to be a future video subscribe hit that bell so you don't miss it and we

237
00:16:50,720 --> 00:16:58,320
will see you there in maybe bad cooling ideas episode two

238
00:16:56,320 --> 00:17:03,759
yeah that might be a good idea and maybe soon and maybe not because ebay shipping

239
00:17:02,000 --> 00:17:08,079
speaking of ebay shipping i'm bringing this sponsor segway right

240
00:17:05,919 --> 00:17:11,280
