00:00:07.839 --> 00:00:14.719
welcome to a very exciting Linus tech tips video you guys have asked for this

00:00:12.240 --> 00:00:20.400
this is the performance evaluation of the kraken x40 and the kraken x60 what's

00:00:17.520 --> 00:00:25.439
the advantage of a kraken versus uh some other liquid cooler well compared to 120

00:00:23.279 --> 00:00:30.080
millimeter radiators it offers 36 percent more surface area which makes it

00:00:27.279 --> 00:00:35.200
more effective for cooling with well larger fans that can push more air with

00:00:32.480 --> 00:00:40.719
lower RPM or well no the same air with lower RPM or more air with the same RPM

00:00:38.640 --> 00:00:45.280
yes either of those things so we're going to be checking out not only the

00:00:42.079 --> 00:00:48.559
kraken x40 but also the kraken x60 which

00:00:45.280 --> 00:00:51.120
has actually whoops not quite made it to

00:00:48.559 --> 00:00:56.079
the test bench yet not every case can accommodate the kraken x40 and x60 you

00:00:53.440 --> 00:01:00.320
have to have for the x40 a 140 millimeter fan mount that has enough

00:00:57.520 --> 00:01:03.680
room around it for you know the tanks at the end of the radiator

00:01:02.000 --> 00:01:07.119
and well the tanks at the end of the radiator as well as the additional

00:01:05.119 --> 00:01:11.040
thickness that's required to have the fan and the crack and mounted there and

00:01:09.119 --> 00:01:18.159
for the kraken x60 you have to have a dual 140 mount with enough clearance for

00:01:14.560 --> 00:01:19.759
a rad and a fan and you have to have the

00:01:18.159 --> 00:01:23.600
correct spacing for the mounting holes or you need to be willing to whip out a

00:01:21.360 --> 00:01:28.000
drill and make it happen which is what we're going to be doing with the

00:01:25.040 --> 00:01:31.759
vengeance c70 here now the vengeance c70 is our standard testing

00:01:30.159 --> 00:01:36.960
bench so i'm going to go through our standard testing procedure really quickly here so number one is we monitor

00:01:35.680 --> 00:01:41.680
the ambient temperature with a multi-logger thermometer so we monitor

00:01:38.880 --> 00:01:46.799
that at the intake on the case that tells us what temperature the air being

00:01:44.479 --> 00:01:50.000
used to cool the computer is then what we do is we correct whatever

00:01:48.320 --> 00:01:53.520
temperatures we get to 20 degrees celsius giving you guys a normalized

00:01:52.399 --> 00:01:58.000
temperature yes it works this way

00:01:55.439 --> 00:02:01.680
don't doubt us on this it's okay if your room temperature goes up 10 degrees your

00:01:59.840 --> 00:02:05.439
CPU temperature will go up exactly 10 degrees so we're reporting what you will

00:02:03.680 --> 00:02:10.399
realistically observe in a sort of a normal climate controlled house

00:02:07.600 --> 00:02:13.840
okay fans we do not use the fans that are included with liquid coolers yes

00:02:12.080 --> 00:02:18.800
there is a value add to the manufacturers including better fans we

00:02:16.239 --> 00:02:25.680
recognize that but we are looking at it in terms of the coolers with a fixed fan

00:02:22.400 --> 00:02:27.360
usage scenario and a fixed noise level

00:02:25.680 --> 00:02:31.360
so we're going to be using high quality Noctua fans in the case of the krakens

00:02:30.080 --> 00:02:38.080
we are not going to be able to use our standard nff12s and we will instead be

00:02:34.160 --> 00:02:40.400
using our standard nf a14 flx fans these

00:02:38.080 --> 00:02:43.840
are both pressure optimized fans but the difference you'll notice is that one of

00:02:41.760 --> 00:02:48.560
them is 140 mil and one of them is 120 mil they spin at the same RPM and are

00:02:46.000 --> 00:02:53.440
approximately the same audible noise level so you know that holds in line

00:02:51.040 --> 00:02:58.000
with our methodology of using them sort of in the way that we would use them

00:02:55.840 --> 00:03:01.680
however we don't run a fan low noise adapter on this one and we do run one on

00:03:00.000 --> 00:03:05.760
the 120 because that's how we get them running at the same RPM we always run

00:03:04.080 --> 00:03:10.959
our benchmarks in a closed case with a real system so

00:03:08.720 --> 00:03:16.159
in this case we're using a gtx 580 from MSI running combustor to generate a heat

00:03:13.519 --> 00:03:20.959
load because in a real system the inside of the system will have other heat

00:03:18.400 --> 00:03:25.519
generating components we're running a 39 30k overclocked to four gigahertz and

00:03:23.840 --> 00:03:29.519
you can see here that we also have a procedure for mounting the fans as well

00:03:27.120 --> 00:03:33.840
this will always have a 120. this will always be dual 120s up here except in

00:03:31.920 --> 00:03:38.319
the case where we are replacing it with 140 millimeters in order to mount a 140

00:03:36.159 --> 00:03:41.920
mil rad so there's the kraken x40 you can see over there what we do for our

00:03:39.920 --> 00:03:47.200
idle test is we just idle it and what we do for our load test is we run combustor

00:03:44.480 --> 00:03:52.239
and prime95 small fft then we take the CPU temperatures after a period of about

00:03:49.599 --> 00:03:55.120
five minutes once they've equalized and report them to you so that's pretty much

00:03:53.840 --> 00:03:59.760
the procedure i can't show you these numbers now because i've gone and removed the side panel and we've changed

00:03:58.239 --> 00:04:04.640
a few things but we've already recorded numbers we're going to go ahead and mount the kraken x60 and show you guys

00:04:02.640 --> 00:04:08.400
what we had to do to a c70 to get it to work

00:04:06.000 --> 00:04:13.599
now with the kraken x60 what we discovered is that compatibility is

00:04:10.879 --> 00:04:18.320
maybe not quite as much of an issue as nzxt and or other case manufacturers

00:04:16.239 --> 00:04:22.479
would have you believe because here is the x60 mounted in a Corsair vengeance

00:04:20.720 --> 00:04:26.080
c70 case which supposedly it doesn't work with

00:04:25.199 --> 00:04:30.560
but we made absolutely no modifications to

00:04:28.320 --> 00:04:33.120
the configuration whatsoever the one challenge you can see we've only mounted

00:04:31.919 --> 00:04:38.240
it with four screws here but we could have put in all eight is that the heads

00:04:35.360 --> 00:04:42.960
of the screws are not that big so we had to kind of sort of you know put them all

00:04:40.800 --> 00:04:45.840
in at the same time otherwise you could kind of you could pop it through if you

00:04:44.320 --> 00:04:49.440
didn't have all the screws in because you can see they're not quite centered

00:04:47.360 --> 00:04:54.320
that was the only issue other than that it mounts fine the clearance is perfect

00:04:51.840 --> 00:04:58.000
uh once we're it once we're inside we have the barbs at the back so if you had

00:04:56.800 --> 00:05:01.600
actually here slick if you want to come around to the other side and give them a

00:05:00.080 --> 00:05:04.560
look inside there and you'll be able to see i hope unless

00:05:03.600 --> 00:05:08.720
your bulk blocks it so the barbs come out

00:05:06.880 --> 00:05:13.120
right above the RAM over there if we had vrm heatsinks over there then that might

00:05:11.440 --> 00:05:15.840
be might be a bit of an issue he wants me to take off the side panel but we

00:05:14.560 --> 00:05:21.199
haven't recorded our temperature readings yet so why don't we do that first remember guys we take all our

00:05:18.960 --> 00:05:25.680
temperature readings with a closed side panel so we recorded our ambience and

00:05:23.360 --> 00:05:30.000
our load temperatures um i just want to remind you that we take the second

00:05:28.080 --> 00:05:33.360
hottest core so in that case it's this guy at 65

00:05:31.759 --> 00:05:37.199
and so we're going to plug that in and find out how this particular cooler

00:05:35.520 --> 00:05:41.759
performs so this is not really what i was

00:05:39.360 --> 00:05:46.720
expecting it does perform better than the x40 so it's about six degrees better

00:05:44.240 --> 00:05:51.120
than the x40 also the fan or the pump is uh very satisfactory on this one we

00:05:48.800 --> 00:05:57.120
don't hear any grinding or or whining but it doesn't perform as much better

00:05:53.039 --> 00:05:59.280
than the h100i as i would have expected

00:05:57.120 --> 00:06:03.280
so that still puts it at the top of our charts i want to be very clear it is

00:06:01.039 --> 00:06:07.440
still the top performing CPU cooler that we've had run through our lab so can't

00:06:05.600 --> 00:06:11.759
take that away from it it's possible that if we had our CPU more overvolted

00:06:09.680 --> 00:06:17.759
or if we had a higher wattage CPU that we'd see it pull away from the h100 more

00:06:14.639 --> 00:06:20.880
it's also possible that the

00:06:17.759 --> 00:06:23.600
the nf f12s being a higher tech fan than

00:06:20.880 --> 00:06:28.160
the a14s are better optimized for pressure even though both sets of fans

00:06:25.280 --> 00:06:32.080
are running at the same RPM and the a14s are inherently larger and should

00:06:30.479 --> 00:06:36.560
therefore be able to push more air through the heatsink uh well heat sink

00:06:34.800 --> 00:06:42.720
radiator whatever you want to call it so here i want to show you guys how the clearance was so if you did have tall

00:06:40.080 --> 00:06:46.080
vrm heatsinks here or up here at the top then you can see that this would not

00:06:44.160 --> 00:06:51.199
have fit but we were able to get it in with our MSI gd65x

00:06:48.479 --> 00:06:54.960
board just fine and you can also see that there's no interference over here

00:06:53.120 --> 00:07:00.160
with any kind of five and a quarter inch bays as well so it's an extremely

00:06:57.520 --> 00:07:03.680
satisfactory installation experience in spite of the fact that this case is not

00:07:01.759 --> 00:07:07.680
listed as compatible so thank you for checking out this episode of Linus tech

00:07:06.160 --> 00:07:12.479
tips where we've had a look at the performance of the kraken x40 and x60 if

00:07:10.639 --> 00:07:15.680
you guys want to see our performance charts we're actually going to have a

00:07:14.000 --> 00:07:20.319
link under the video so you can go ahead and check those out at your leisure so you

00:07:18.240 --> 00:07:24.639
can see all of our results for various coolers on our standard test bench and

00:07:22.960 --> 00:07:29.680
we're going to keep updating that over time don't forget to subscribe

00:07:27.680 --> 00:07:34.240
obviously no review of the krakens would be complete without having a look at the

00:07:31.680 --> 00:07:38.160
included software now we had CPU temperatures working before i had to

00:07:35.919 --> 00:07:41.840
reinstall this just now so that might just be sort of a weird thing and fan

00:07:40.319 --> 00:07:44.720
speed does work we just don't have the fans plugged in right now but i just

00:07:43.360 --> 00:07:49.599
want to show you guys the feature so you can monitor your pump speed you can know if your pump failed you can see the

00:07:47.759 --> 00:07:53.440
liquid temperature as well as CPU temperature so you can monitor your

00:07:50.960 --> 00:07:57.360
deltas here's a graph of fan speed RPM as well as temperature fan settings

00:07:55.520 --> 00:08:02.400
these are cool so you can set up a few different curves one for silent so you

00:07:59.599 --> 00:08:06.080
can see that the fan speed here on the y-axis doesn't start ramping up until

00:08:04.160 --> 00:08:10.000
the temperature here on the x-axis starts to get up to around 45 degrees

00:08:08.319 --> 00:08:13.919
you can actually move these around so you can make things as extreme or

00:08:12.639 --> 00:08:17.759
well that's a hundred so you can't really go any higher than that but

00:08:16.080 --> 00:08:21.919
oh it's not going to let me move that no okay well interesting maybe the custom

00:08:19.759 --> 00:08:27.199
one will let me move that oh no it just wants you sort of it wants

00:08:24.560 --> 00:08:31.039
100 to be around 65 degrees and then you could i mean you could also just go 100

00:08:28.960 --> 00:08:35.599
earlier if you wanted so there is a lot that you can do to play around with it

00:08:33.279 --> 00:08:40.320
uh and then right so you can just change the dial to extreme silent or custom

00:08:38.000 --> 00:08:43.919
whatever you prefer and light settings so it's got RGB leds inside you can

00:08:42.399 --> 00:08:47.920
change the colors you can actually have different colors if the temperatures are

00:08:45.760 --> 00:08:51.440
high you can have it fade and strobe at intervals and general settings are here

00:08:50.000 --> 00:08:54.880
so you can monitor in fahrenheit if you're from the us of a

00:08:53.279 --> 00:08:58.880
and auto start liquid temperature notifications all that kind of good stuff so

00:08:57.440 --> 00:09:03.040
uh once again don't forget to subscribe to Linus tech tips for more unboxings reviews and other incomplete videos

00:09:01.600 --> 00:09:08.480
until we come back and finish them and then they're done and then now we can actually say bye and turn the camera off
