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

00:00:03.520 --> 00:00:09.679
metal you take a plastic fan and you slap it

00:00:07.040 --> 00:00:13.920
on there in hopes that the raging inferno of a pentium d processor you've

00:00:12.400 --> 00:00:17.840
got will stay alive long enough to become a weird curiosity for the

00:00:15.599 --> 00:00:22.080
employees you hire 10 years down the line who were still in diapers when you

00:00:20.240 --> 00:00:28.960
started building computers but not thermal take

00:00:24.960 --> 00:00:32.399
no thermaltake took a metal heatsink

00:00:28.960 --> 00:00:33.920
okay i'm with you so far slapped a metal

00:00:32.399 --> 00:00:40.719
fan onto it because yolo in an attempt to cool down

00:00:37.600 --> 00:00:43.600
a modern CPU in one of the smallest form

00:00:40.719 --> 00:00:46.879
factor coolers that i've ever seen but does it work

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

00:01:00.000 --> 00:01:05.119
sorely disappointed because i'm also going to bore you with some science and

00:01:04.080 --> 00:01:12.240
history the sandia cooler concept with its metal

00:01:08.159 --> 00:01:15.439
spinning top and static metal base first

00:01:12.240 --> 00:01:18.240
showed up on the scene in 2012

00:01:15.439 --> 00:01:23.680
with this video gaining considerable attention among pc enthusiasts due to

00:01:21.119 --> 00:01:29.439
its promises of vastly improved efficiency smaller size and quieter

00:01:27.200 --> 00:01:34.400
operation compared to more traditional heat sink designs

00:01:31.200 --> 00:01:37.840
then there was no news until cooler

00:01:34.400 --> 00:01:40.720
master showed up at ces 2015 with a

00:01:37.840 --> 00:01:45.680
couple kind of ugly prototypes that featured grooves between the spinning

00:01:42.960 --> 00:01:52.000
top and the base presumably to improve heat transfer and an outer heat sink to

00:01:49.200 --> 00:01:57.040
further improve cooling performance fast forward to today and this tech is

00:01:54.880 --> 00:02:02.320
finally on the market the fundamental idea here is pretty

00:01:59.280 --> 00:02:04.799
simple theoretically when the air gap

00:02:02.320 --> 00:02:09.759
between the fixed grooved metal base and the spinning grooved metal impeller is

00:02:07.119 --> 00:02:16.080
small enough heat transfer can still occur as though they were connected

00:02:12.800 --> 00:02:18.640
in practice this was pretty difficult to

00:02:16.080 --> 00:02:24.640
pull off but through a combination of patients and apparently balancing the

00:02:21.440 --> 00:02:28.080
impeller like the wheel on a car

00:02:24.640 --> 00:02:30.879
thermaltake was the first one to do it

00:02:28.080 --> 00:02:34.959
to test how effective the engine 27 was we gathered up a bunch of other small

00:02:32.959 --> 00:02:39.440
form factor coolers from reputable brands and

00:02:36.560 --> 00:02:43.519
a stock Intel heatsink since if it doesn't offer a compelling improvement

00:02:41.280 --> 00:02:48.000
over that you're clearly better off saving your money

00:02:44.879 --> 00:02:51.440
we used an ASUS z170i pro gaming

00:02:48.000 --> 00:02:55.519
motherboard thanks bros and a core i7

00:02:51.440 --> 00:02:56.560
6700k with an nzxt grid 2.0 for fan

00:02:55.519 --> 00:03:01.599
control for each test we used a p sized amount

00:02:58.879 --> 00:03:07.760
of ic diamond thermal compound and we analyzed the results two different ways

00:03:04.879 --> 00:03:14.319
first we looked at what we could expect from each cooler out of the box using

00:03:10.560 --> 00:03:15.599
the silent mode curve in nzxt's cam

00:03:14.319 --> 00:03:21.760
software the engine 27 was the worst performing

00:03:18.560 --> 00:03:23.840
cooler in this test at about 10 degrees

00:03:21.760 --> 00:03:28.640
higher than the nearest aftermarket competitor under load and all of this

00:03:26.400 --> 00:03:35.120
while managing to be louder than the Intel box cooler as measured by our

00:03:31.360 --> 00:03:37.680
extech 407 750 digital sound level meter

00:03:35.120 --> 00:03:43.519
the second method of analysis was to introduce a noise ceiling

00:03:40.159 --> 00:03:46.080
limiting the maximum RPM of each cooler

00:03:43.519 --> 00:03:51.120
to the speed at which it reaches 45 decibels the same as the stock cooler

00:03:48.959 --> 00:03:56.640
so performing worse than the stock cooler or thermal throttling would

00:03:53.519 --> 00:03:59.599
result in a fail grade for this test

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

00:04:02.319 --> 00:04:09.599
enough air flow to the components nearby is of critical importance the good news

00:04:07.519 --> 00:04:16.479
is that all of our coolers performed similarly with the c7 only pulling ahead

00:04:13.120 --> 00:04:18.560
when we allowed it to get a little noisy

00:04:16.479 --> 00:04:24.160
leading us finally to the reason presumably that thermaltakes engineers

00:04:20.959 --> 00:04:26.080
thought the engine 27 deserved to exist

00:04:24.160 --> 00:04:31.440
its size it's not the top performer in any

00:04:28.800 --> 00:04:35.919
category but this one at a full centimeter shorter than the nearest

00:04:33.199 --> 00:04:41.840
competitor from Noctua and less than half the height of the top performing

00:04:38.320 --> 00:04:44.320
ar-06 from silverstone the engine 27 is

00:04:41.840 --> 00:04:49.280
compatible with any case that's wide enough to fit a memory stick

00:04:46.720 --> 00:04:55.280
so with form factor as a consideration i'll be giving a few awards here today

00:04:51.520 --> 00:04:57.759
the ar06 gets my big and beautiful award

00:04:55.280 --> 00:05:02.560
for being the best performer if a little top heavy

00:04:58.960 --> 00:05:05.199
the Noctua nhl9i takes home the middle

00:05:02.560 --> 00:05:10.960
child award for being so ugly only its own mother could love it but otherwise a

00:05:07.840 --> 00:05:13.600
solid compact choice and the thermaltake

00:05:10.960 --> 00:05:18.560
engine 27 gets my better than nothing award for working better than i expected

00:05:16.000 --> 00:05:22.639
given its size making it a great option if you don't have anything else that

00:05:20.320 --> 00:05:29.759
will fit so congrats to the winners thanks for watching and good night

00:05:26.240 --> 00:05:33.520
and i've got another award this time for

00:05:29.759 --> 00:05:38.160
one of our lucky viewers we are hooking

00:05:33.520 --> 00:05:40.800
one of you up with the SSD to go pkt

00:05:38.160 --> 00:05:45.360
from angel bird they set us up with these bad boys for ces 2017. you can

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

00:05:48.400 --> 00:05:54.600
with a silk screened LTT super fan like

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

00:05:58.560 --> 00:06:05.120
tiny it's usb 3.1 with either a type a

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

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

00:06:12.639 --> 00:06:17.199
in the video description

00:06:15.759 --> 00:06:20.400
so thanks again for watching guys if you disliked dislike if you liked then like

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

00:06:23.360 --> 00:06:28.319
description you can also join our community forum and i'm pretty sure

00:06:26.960 --> 00:06:31.520
there's something else down there right cool t-shirts like the one that i am

00:06:30.000 --> 00:06:34.960
wearing i think that's pretty much it subscribe

00:06:33.440 --> 00:06:39.000
blah blah blah blah right check out our other videos like that one
