overdue unboxing of Cooler Master siden 120 XL and siden

5
00:00:17,920 --> 00:00:26,880
240m liquid coolers now the first thing I noticed about these is check this out

6
00:00:24,000 --> 00:00:32,800
Cooler Master has gone ahead and put compatibility for LGA 1150 right on the

7
00:00:29,640 --> 00:00:36,879
box now it should be noted that LGA 1150

8
00:00:32,800 --> 00:00:40,200
which is for Haswell or Intel Core i7 i5

9
00:00:36,879 --> 00:00:41,559
and I3 fourth generation processors is

10
00:00:40,200 --> 00:00:47,719
not really going to be any different from 1155 or 1156 in terms of heat SN

11
00:00:45,520 --> 00:00:51,039
compatibility but I mean it's just one of those things where it's always it

12
00:00:48,879 --> 00:00:54,760
always amuses me when there are coolers being announced and being shipped that

13
00:00:53,079 --> 00:01:00,320
have compatibility for an upcoming socket when you actually can't buy said

14
00:00:57,280 --> 00:01:02,000
socket yet so the main difference

15
00:01:00,320 --> 00:01:07,040
between these two coolers is going to be in terms of the size which is a little

16
00:01:04,000 --> 00:01:09,880
bit funny to me because the 120 is the

17
00:01:07,040 --> 00:01:14,280
XL and the 240 is the m which in terms of North American sizing usually

18
00:01:11,640 --> 00:01:20,119
indicates extra large and medium whereas the 240 mm one is definitely extra

19
00:01:16,479 --> 00:01:21,840
larger than the mediumsized 120 mm one

20
00:01:20,119 --> 00:01:25,600
so let's go ahead and check out what cooler Master's done in terms of

21
00:01:23,360 --> 00:01:28,560
packaging here so these are liquid Co these are pre-done liquid coolers so

22
00:01:27,439 --> 00:01:32,799
actually okay fine we'll start with the outside so they are maintenance free

23
00:01:30,640 --> 00:01:37,880
they're designed for overclocking they use an ultra fine microchannel design

24
00:01:35,640 --> 00:01:43,320
for the CPU block itself now what you're going to see right here guys is that

25
00:01:39,880 --> 00:01:46,240
this is not an acch and it is not a

26
00:01:43,320 --> 00:01:49,840
kolet design so Cooler Master has wanted to differentiate themselves from what

27
00:01:48,399 --> 00:01:54,320
the other guys in the market are doing and they have done that by well not

28
00:01:52,960 --> 00:01:57,600
doing what everyone else in the market is doing which is sort of one way to

29
00:01:56,000 --> 00:02:00,479
differentiate yourself from what everyone else is doing on the back you

30
00:01:59,079 --> 00:02:04,000
find I'll to find my mic channel so pretty much the same a hot durable and

31
00:02:02,360 --> 00:02:08,200
Powerful water pump dissipates heat effectively and maintains temperatures

32
00:02:05,680 --> 00:02:11,560
throughout the stable water circulation all that kind of good stuff okay so

33
00:02:09,440 --> 00:02:16,400
let's go ahead and start with the 120 in terms of what's inside we've got some

34
00:02:13,879 --> 00:02:21,360
foam on the top we've got mounting hardware which we will be unfamiliar

35
00:02:18,560 --> 00:02:26,000
with because it is not the standard acch or kolet mounting hardware so let's go

36
00:02:23,800 --> 00:02:32,000
ahead and see what we got here oh I love this nice solid pieces of everything see

37
00:02:29,519 --> 00:02:36,280
see solid steel mounting plate so there's your AMD mounting hardware at

38
00:02:33,599 --> 00:02:41,200
any rate all right there is your Intel mounting hardware so you can see that

39
00:02:37,599 --> 00:02:43,200
screw is able to adjust in position see

40
00:02:41,200 --> 00:02:48,720
moves over clicks into place just like that you've got a back plate for Intel

41
00:02:45,920 --> 00:02:55,360
so this pops into uh different positions as well so it has full compatibility for

42
00:02:50,599 --> 00:02:57,400
775 1155 1156 1150 2,1 1366 all the

43
00:02:55,360 --> 00:03:00,080
sockets you could possibly want an AMD because they haven't changed their

44
00:02:58,440 --> 00:03:03,920
mounting hardware in like a bajil Generations is pretty much the same as

45
00:03:01,720 --> 00:03:09,000
before same thing here nice solid mounting screws these ones look like

46
00:03:05,560 --> 00:03:11,440
they're for LGA oh oh they could be for

47
00:03:09,000 --> 00:03:16,760
a number of different things but okay there you go again more solid pieces

48
00:03:14,120 --> 00:03:21,239
here so it looks like the way it mounts is the back plate comes through the

49
00:03:18,799 --> 00:03:25,560
board goes into one of these guys and then the cooler itself mounts to that

50
00:03:23,920 --> 00:03:28,200
piece from the other side from the top I like this system there's a number of

51
00:03:26,920 --> 00:03:33,480
different coolers that have used it in the past and I find it very solid very

52
00:03:30,760 --> 00:03:37,879
sturdy and works very very well they've also included a splitter for the two

53
00:03:34,959 --> 00:03:43,040
fans so there's a pwm splitter which is awesome because it means that you can

54
00:03:40,159 --> 00:03:47,480
provide pwm control for both of the fans without actually or yeah without

55
00:03:45,239 --> 00:03:53,640
actually um having to run one of them off of DC and I mean honestly a lot of

56
00:03:50,680 --> 00:03:59,519
motherboards might have all the pwm fan connectors in the world on them but it

57
00:03:55,400 --> 00:04:01,360
doesn't always work correctly uh so

58
00:03:59,519 --> 00:04:05,519
there there you go it's nice to be able to split the CPU on a lot of the time

59
00:04:03,640 --> 00:04:09,760
they aren't uh controllable to with the same degree of

60
00:04:07,280 --> 00:04:14,040
finitude as the one for the CPU connector is so this is a nice touch

61
00:04:11,720 --> 00:04:19,079
Cooler Master includes a couple of 120 mm fans and they also include a couple

62
00:04:16,040 --> 00:04:20,560
of nice rubber isolating mounts for them

63
00:04:19,079 --> 00:04:25,360
so you don't have to worry about any vibrations being transferred to your

64
00:04:23,199 --> 00:04:29,440
case and causing your computer to be louder than necessary all right these

65
00:04:27,919 --> 00:04:33,240
are intended to be installed in a push pull configuration cuz if you set them

66
00:04:31,320 --> 00:04:41,360
both to push or both to pull you're going to have yourself one heck of a

67
00:04:37,600 --> 00:04:43,680
problem this radiator is optimized for

68
00:04:41,360 --> 00:04:47,479
um sort of I guess I'd go sort of mid-range in terms of do you have to

69
00:04:45,800 --> 00:04:51,400
have high RPM do you have to can you get away with low RPM because the fin

70
00:04:49,440 --> 00:04:55,759
spacing isn't particularly dense which is great for low RPM quiet operation but

71
00:04:54,000 --> 00:05:00,000
it is a thicker radiator than you find on most 120 mm coolers meaning you'll

72
00:04:58,520 --> 00:05:04,080
get a little bit more performance out of it but you also have to have a little

73
00:05:01,880 --> 00:05:07,479
bit more static pressure to the fans in order to draw the air that you need

74
00:05:05,639 --> 00:05:11,720
through it you can see how Cooler Master fills their water cooler so there's a

75
00:05:09,759 --> 00:05:14,280
little warranty void if removed plug right there that shouldn't get in the

76
00:05:12,800 --> 00:05:18,039
way of anything because once you go ahead and install a fan on it it's not

77
00:05:16,240 --> 00:05:23,560
really any higher profile than a fan would be and they're using a/4 in

78
00:05:20,639 --> 00:05:27,440
corrugated plastic tubing approach that has been in use for well years now on

79
00:05:25,680 --> 00:05:31,240
these pre-filled liquid coolers and there haven't really been any notable

80
00:05:29,039 --> 00:05:35,319
problems with them there's also a rotating uh fitting right here so you're

81
00:05:33,759 --> 00:05:42,800
going to have the flexibility to mount it either sort of this way facing down

82
00:05:38,960 --> 00:05:47,039
or if you rotate those like

83
00:05:42,800 --> 00:05:49,039
that this way facing up just like that

84
00:05:47,039 --> 00:05:54,440
it uses aluminum fins for the radiator itself but there are copper tubes as

85
00:05:51,479 --> 00:05:57,840
well as copper tanks and a copper bottom for the block itself you can see they're

86
00:05:56,080 --> 00:06:02,639
using a security bit here I actually have one of these so I could take it apart if I felt like it but they're

87
00:06:00,560 --> 00:06:06,560
using a security bit to prevent users from taking apart the unit which is not

88
00:06:04,560 --> 00:06:12,960
what it is intended for it is meant to be maintenance free and not opened up or

89
00:06:10,560 --> 00:06:17,479
anything sort of bad like that all right so let's have a look at the 240 mm

90
00:06:14,919 --> 00:06:22,479
version we've got two of the same fans uh it looks like the noise isolating

91
00:06:19,800 --> 00:06:28,280
rubber mounts are not included at least on the fans themselves uh yes here they

92
00:06:24,919 --> 00:06:31,039
are so those are included instead in a

93
00:06:28,280 --> 00:06:35,319
very heavy I love heavy mounting hardware it makes me just feel that much

94
00:06:33,000 --> 00:06:38,039
more reassured about it so there are a couple of them in with the rest of the

95
00:06:36,639 --> 00:06:42,759
mounting hardware where there's thermal compound just like the 120 mm version a

96
00:06:40,800 --> 00:06:48,080
fan splitter just like the 120 mm version and then just more of the same

97
00:06:45,080 --> 00:06:49,759
mounting hardware so this is for um

98
00:06:48,080 --> 00:06:53,639
instead of having it in two separate bags it looks like they've done just one

99
00:06:51,479 --> 00:06:58,520
bag for the 240 mil version the radiator itself is a thinner

100
00:06:56,879 --> 00:07:03,560
style radiator so you're going to see this one is I'd say mid thickness for

101
00:07:00,919 --> 00:07:06,960
the 120 mil and then this is more like standard thickness and then there are

102
00:07:05,160 --> 00:07:10,800
some that are actually larger and thicker than this one but those are

103
00:07:09,120 --> 00:07:14,319
those are much more rare than these ones and that's for compatibility reasons not

104
00:07:12,919 --> 00:07:17,560
all cases are compatible with the thicker style radiators this one in

105
00:07:16,240 --> 00:07:21,400
order to make sure that it gets the performance it needs uses a much more

106
00:07:19,479 --> 00:07:27,120
dense fin Arrangement right here so you can see that it's all about surface area

107
00:07:23,960 --> 00:07:29,240
guys so if you have a thicker radiator

108
00:07:27,120 --> 00:07:32,199
and you use a less dense fin Arrangement versus versus if you have a thinner

109
00:07:30,639 --> 00:07:36,599
radiator and you use a more dense thin Arrangement what you've done is you've

110
00:07:33,800 --> 00:07:40,280
actually in both cases increased the resistance to air passing through but

111
00:07:38,720 --> 00:07:43,520
also increased your surface area and improved performance so generally

112
00:07:41,720 --> 00:07:47,199
speaking the less dense the more optimized it is for low RPM fans and the

113
00:07:45,680 --> 00:07:51,879
thinner it is the more optimized it is for low RPM fans whereas if you were to

114
00:07:49,720 --> 00:07:56,000
put even double the density in here and put like you know jet turbine fans on it

115
00:07:54,520 --> 00:08:02,319
you could squeeze more performance out of this form factor because surface area

116
00:07:58,960 --> 00:08:04,000
is King and that's why the 120 dual 120

117
00:08:02,319 --> 00:08:08,599
mm version will perform better than the single 120 mm version so you've got that

118
00:08:06,720 --> 00:08:13,680
same fill Point here at the top that says do not tamper with or remove please

119
00:08:11,479 --> 00:08:19,240
don't do that same corrugated plastic quarter inch fittings or hoses as well

120
00:08:16,720 --> 00:08:23,919
as the same rotating fittings down here at the bottom attached to the same block

121
00:08:21,840 --> 00:08:27,800
and pump combo this is why I did these unboxings together we've got a copper

122
00:08:25,879 --> 00:08:31,680
plate at the bottom that looks looks flat anyway it's hard to oh no it's

123
00:08:29,919 --> 00:08:35,680
bowed there you go I wonder if the other one is as well you can tell if you look

124
00:08:34,440 --> 00:08:42,039
at them in the light just right yep they're both bowed so what that does is it increases contact pressure and

125
00:08:39,440 --> 00:08:45,160
reduces temperatures uh as long as you design a mounting mechanism that's

126
00:08:43,440 --> 00:08:48,959
correctly sort of optimized for it so if you have a CPU here and then you have a

127
00:08:47,080 --> 00:08:52,399
bow so this is flat and this is Bowe and you have a bow surface and then you

128
00:08:50,440 --> 00:08:55,480
clamp it down what can happen is you can end up with two flat mating surfaces

129
00:08:54,040 --> 00:09:01,279
whereas if you take two flat mating surfaces and you clamp this down a lot at the edges you can end up with a C it

130
00:08:59,680 --> 00:09:06,720
in the middle we discovered this or must have been back in around 2008 2009 dtec

131
00:09:04,880 --> 00:09:10,120
figured it out with their Bode block that they were putting O-rings in in

132
00:09:08,079 --> 00:09:14,000
order to to bow out the base of it and get a tighter mounting point so there's

133
00:09:12,519 --> 00:09:17,320
a little water cooling history lesson for you Cooler Master is using a very

134
00:09:15,720 --> 00:09:20,600
high quality sleeving on the connector so the pump is powered by a three pin

135
00:09:19,279 --> 00:09:27,320
that you really can't see any of the color of the wires inside I like this it's a nice touch makes your build look

136
00:09:23,640 --> 00:09:29,040
nice and they include of course detailed

137
00:09:27,320 --> 00:09:33,240
instructions cooler Master's been doing liquid coolers for and just coolers in

138
00:09:31,440 --> 00:09:39,040
general for a long time so I wouldn't expect anything

139
00:09:35,320 --> 00:09:41,560
except nice detailed multilingual

140
00:09:39,040 --> 00:09:44,720
instructions for every possible socket and everything labeled and all those

141
00:09:43,279 --> 00:09:49,279
sort of good things done it looks like the same instructions for the 120 or the

142
00:09:46,519 --> 00:09:52,839
240 mm don't forget to subscribe to lus Tech tips for more unboxings reviews and

143
00:09:51,399 --> 00:09:58,279
other computer videos and thank you for checking out my video on the seiden 120m

144
00:09:55,839 --> 00:10:03,360
and the or see I did it there the siden 12 XL and theid in 240 m
