00:00:00,160 --> 00:00:04,400
okay so the traditional way of building a CPU cooler you take a big old hunk of

2
00:00:03,520 --> 00:00:09,679
metal you take a plastic fan and you slap it

3
00:00:07,040 --> 00:00:13,920
on there in hopes that the raging inferno of a pentium d processor you've

4
00:00:12,400 --> 00:00:17,840
got will stay alive long enough to become a weird curiosity for the

5
00:00:15,599 --> 00:00:22,080
employees you hire 10 years down the line who were still in diapers when you

6
00:00:20,240 --> 00:00:28,960
started building computers but not thermal take

7
00:00:24,960 --> 00:00:32,399
no thermaltake took a metal heatsink

8
00:00:28,960 --> 00:00:33,920
okay i'm with you so far slapped a metal

9
00:00:32,399 --> 00:00:40,719
fan onto it because yolo in an attempt to cool down

10
00:00:37,600 --> 00:00:43,600
a modern CPU in one of the smallest form

11
00:00:40,719 --> 00:00:46,879
factor coolers that i've ever seen but does it work

12
00:00:55,280 --> 00:01:01,680
so if you were just here to find out if a metal fan would work then you'll be

13
00:01:00,000 --> 00:01:05,119
sorely disappointed because i'm also going to bore you with some science and

14
00:01:04,080 --> 00:01:12,240
history the sandia cooler concept with its metal

15
00:01:08,159 --> 00:01:15,439
spinning top and static metal base first

16
00:01:12,240 --> 00:01:18,240
showed up on the scene in 2012

17
00:01:15,439 --> 00:01:23,680
with this video gaining considerable attention among pc enthusiasts due to

18
00:01:21,119 --> 00:01:29,439
its promises of vastly improved efficiency smaller size and quieter

19
00:01:27,200 --> 00:01:34,400
operation compared to more traditional heat sink designs

20
00:01:31,200 --> 00:01:37,840
then there was no news until cooler

21
00:01:34,400 --> 00:01:40,720
master showed up at ces 2015 with a

22
00:01:37,840 --> 00:01:45,680
couple kind of ugly prototypes that featured grooves between the spinning

23
00:01:42,960 --> 00:01:52,000
top and the base presumably to improve heat transfer and an outer heat sink to

24
00:01:49,200 --> 00:01:57,040
further improve cooling performance fast forward to today and this tech is

25
00:01:54,880 --> 00:02:02,320
finally on the market the fundamental idea here is pretty

26
00:01:59,280 --> 00:02:04,799
simple theoretically when the air gap

27
00:02:02,320 --> 00:02:09,759
between the fixed grooved metal base and the spinning grooved metal impeller is

28
00:02:07,119 --> 00:02:16,080
small enough heat transfer can still occur as though they were connected

29
00:02:12,800 --> 00:02:18,640
in practice this was pretty difficult to

30
00:02:16,080 --> 00:02:24,640
pull off but through a combination of patients and apparently balancing the

31
00:02:21,440 --> 00:02:28,080
impeller like the wheel on a car

32
00:02:24,640 --> 00:02:30,879
thermaltake was the first one to do it

33
00:02:28,080 --> 00:02:34,959
to test how effective the engine 27 was we gathered up a bunch of other small

34
00:02:32,959 --> 00:02:39,440
form factor coolers from reputable brands and

35
00:02:36,560 --> 00:02:43,519
a stock Intel heatsink since if it doesn't offer a compelling improvement

36
00:02:41,280 --> 00:02:48,000
over that you're clearly better off saving your money

37
00:02:44,879 --> 00:02:51,440
we used an ASUS z170i pro gaming

38
00:02:48,000 --> 00:02:55,519
motherboard thanks bros and a core i7

39
00:02:51,440 --> 00:02:56,560
6700k with an nzxt grid 2.0 for fan

40
00:02:55,519 --> 00:03:01,599
control for each test we used a p sized amount

41
00:02:58,879 --> 00:03:07,760
of ic diamond thermal compound and we analyzed the results two different ways

42
00:03:04,879 --> 00:03:14,319
first we looked at what we could expect from each cooler out of the box using

43
00:03:10,560 --> 00:03:15,599
the silent mode curve in nzxt's cam

44
00:03:14,319 --> 00:03:21,760
software the engine 27 was the worst performing

45
00:03:18,560 --> 00:03:23,840
cooler in this test at about 10 degrees

46
00:03:21,760 --> 00:03:28,640
higher than the nearest aftermarket competitor under load and all of this

47
00:03:26,400 --> 00:03:35,120
while managing to be louder than the Intel box cooler as measured by our

48
00:03:31,360 --> 00:03:37,680
extech 407 750 digital sound level meter

49
00:03:35,120 --> 00:03:43,519
the second method of analysis was to introduce a noise ceiling

50
00:03:40,159 --> 00:03:46,080
limiting the maximum RPM of each cooler

51
00:03:43,519 --> 00:03:51,120
to the speed at which it reaches 45 decibels the same as the stock cooler

52
00:03:48,959 --> 00:03:56,640
so performing worse than the stock cooler or thermal throttling would

53
00:03:53,519 --> 00:03:59,599
result in a fail grade for this test

54
00:03:56,640 --> 00:04:05,040
all of them passed but CPU cooling isn't the be-all and end-all and maintaining

55
00:04:02,319 --> 00:04:09,599
enough air flow to the components nearby is of critical importance the good news

56
00:04:07,519 --> 00:04:16,479
is that all of our coolers performed similarly with the c7 only pulling ahead

57
00:04:13,120 --> 00:04:18,560
when we allowed it to get a little noisy

58
00:04:16,479 --> 00:04:24,160
leading us finally to the reason presumably that thermaltakes engineers

59
00:04:20,959 --> 00:04:26,080
thought the engine 27 deserved to exist

60
00:04:24,160 --> 00:04:31,440
its size it's not the top performer in any

61
00:04:28,800 --> 00:04:35,919
category but this one at a full centimeter shorter than the nearest

62
00:04:33,199 --> 00:04:41,840
competitor from Noctua and less than half the height of the top performing

63
00:04:38,320 --> 00:04:44,320
ar-06 from silverstone the engine 27 is

64
00:04:41,840 --> 00:04:49,280
compatible with any case that's wide enough to fit a memory stick

65
00:04:46,720 --> 00:04:55,280
so with form factor as a consideration i'll be giving a few awards here today

66
00:04:51,520 --> 00:04:57,759
the ar06 gets my big and beautiful award

67
00:04:55,280 --> 00:05:02,560
for being the best performer if a little top heavy

68
00:04:58,960 --> 00:05:05,199
the Noctua nhl9i takes home the middle

69
00:05:02,560 --> 00:05:10,960
child award for being so ugly only its own mother could love it but otherwise a

70
00:05:07,840 --> 00:05:13,600
solid compact choice and the thermaltake

71
00:05:10,960 --> 00:05:18,560
engine 27 gets my better than nothing award for working better than i expected

72
00:05:16,000 --> 00:05:22,639
given its size making it a great option if you don't have anything else that

73
00:05:20,320 --> 00:05:29,759
will fit so congrats to the winners thanks for watching and good night

74
00:05:26,240 --> 00:05:33,520
and i've got another award this time for

75
00:05:29,759 --> 00:05:38,160
one of our lucky viewers we are hooking

76
00:05:33,520 --> 00:05:40,800
one of you up with the SSD to go pkt

77
00:05:38,160 --> 00:05:45,360
from angel bird they set us up with these bad boys for ces 2017. you can

78
00:05:43,680 --> 00:05:52,639
check them out in our gear bag video over here and they gave us an extra one

79
00:05:48,400 --> 00:05:54,600
with a silk screened LTT super fan like

80
00:05:52,639 --> 00:06:02,800
logo thing on it and everything it's a 256 gig portable SSD drive it's super

81
00:05:58,560 --> 00:06:05,120
tiny it's usb 3.1 with either a type a

82
00:06:02,800 --> 00:06:10,240
or a type c connection to your computer and it can handle up to 560 megabyte per

83
00:06:08,240 --> 00:06:15,759
second transfer speeds so all you got to do to enter to win is check out the link

84
00:06:12,639 --> 00:06:17,199
in the video description

85
00:06:15,759 --> 00:06:20,400
so thanks again for watching guys if you disliked dislike if you liked then like

86
00:06:18,960 --> 00:06:25,199
if you really liked then maybe check out where to buy the stuff we featured at the link to amazon in the video

87
00:06:23,360 --> 00:06:28,319
description you can also join our community forum and i'm pretty sure

88
00:06:26,960 --> 00:06:31,520
there's something else down there right cool t-shirts like the one that i am

89
00:06:30,000 --> 00:06:34,960
wearing i think that's pretty much it subscribe

90
00:06:33,440 --> 00:06:39,000
blah blah blah blah right check out our other videos like that one
