00:00:00.040 --> 00:00:05.960
welcome back to the workshop today we're going to be investigating radiator fan

00:00:04.080 --> 00:00:11.200
configuration we're using a Corsair h100i GTX it's not a graphics card don't

00:00:09.040 --> 00:00:16.279
know why it has GTX in it but anyways and some Noctua nff 12s in a bunch of

00:00:13.920 --> 00:00:20.640
different configurations so check out the straw pole link down below vote on

00:00:18.600 --> 00:00:31.400
which configuration you think is going to win and let's do this

00:00:31.400 --> 00:00:37.680
Corsair claims unrivaled comfort and Universal compatibility on its new void

00:00:35.559 --> 00:00:42.800
surround headset featuring genuine Dolby 7.1 headphone USB adapter click the link

00:00:40.600 --> 00:00:47.000
in the video description to learn more our first test we're going to have our

00:00:44.039 --> 00:00:51.480
nff 12's pushing air up through the radiator just two fans nothing super

00:00:49.800 --> 00:00:55.800
crazy with push pull configurations or whatever super simple test also in AI

00:00:54.359 --> 00:01:01.160
Suite in the motherboard we have them pinned at 60% with all of these tests

00:00:58.920 --> 00:01:05.760
people go like oh well maybe the fan speed was changing which is why the

00:01:02.879 --> 00:01:10.240
thermal paste application didn't change no the fan speed is static in all these

00:01:08.080 --> 00:01:16.880
tests it's not changing if it changes it might change by like 10 RPM which just

00:01:12.479 --> 00:01:18.640
doesn't at all matter so to Ida 64 we go

00:01:16.880 --> 00:01:23.240
let's test out our first configuration so with the two Noctua n2s pushing up

00:01:21.119 --> 00:01:30.280
through the radiator at an ambient room temperature of 18.1 de the core ran at

00:01:27.200 --> 00:01:32.399
38° this is all done in Celsius we've

00:01:30.280 --> 00:01:37.600
got our good kind of starting number let's move on forward so now the fans

00:01:34.640 --> 00:01:43.159
are configured to pull air down through the radiator and into the case so

00:01:40.200 --> 00:01:51.040
currently the air flow is sucking in that way so running id64 again start

00:01:48.520 --> 00:01:55.360
test and we'll see you in 10 minutes okay so with the Noctua pulling down

00:01:53.000 --> 00:01:59.920
through the rad we had a room ambient temperature of

00:01:56.719 --> 00:02:01.640
18.3 and yet again a core temperature of

00:01:59.920 --> 00:02:06.680
38 so that really didn't make any difference having them push up or pull

00:02:04.320 --> 00:02:12.680
down so moving on we're going to start doing two sets of fans so this would

00:02:10.679 --> 00:02:17.280
increase your costs by a fair amount because a lot of coolers including this

00:02:14.440 --> 00:02:20.800
one will come with two fans but not four so if you want to move up to four your

00:02:19.080 --> 00:02:26.560
costs are going to go up a whole bunch so for this to be worth it we need the

00:02:24.400 --> 00:02:31.319
cooling to have a significant Improvement just something to keep in

00:02:28.040 --> 00:02:34.680
mind all right so now I have two sets of

00:02:31.319 --> 00:02:36.120
fans both pulling down into the case so

00:02:34.680 --> 00:02:39.480
one set pushing down through the radiator another set pulling down

00:02:37.959 --> 00:02:45.400
through the radiator we're going to check in 10 minutes and there we go see

00:02:42.800 --> 00:02:51.000
you later that equaled an ambient temperature of 18.5 de and an actual red

00:02:49.319 --> 00:02:58.360
out from the computer temperature for the core of 35° so we saw an improvement

00:02:54.599 --> 00:03:01.319
of 3° but you did add two n12 fans which

00:02:58.360 --> 00:03:05.120
is like a fair amount of cost so just keep that in mind next up we're going to

00:03:03.440 --> 00:03:10.040
do a pretty stupid configuration we're going to have the fans on top trying to

00:03:07.400 --> 00:03:13.680
pull up through the radiator and we're going to have the fans on the bottom

00:03:11.400 --> 00:03:19.879
trying to push down through the radiator so opposite directions super weird just

00:03:17.360 --> 00:03:25.440
going to see what what it does I guess Workshop yeah okay so short answer don't

00:03:23.159 --> 00:03:33.360
do that long answer the ambient in the room was 18.7 de and the temperature of

00:03:29.360 --> 00:03:38.319
the Cor was 48° so not great it

00:03:33.360 --> 00:03:39.959
increased by like 10° C which is bad so

00:03:38.319 --> 00:03:45.400
yeah don't have it so that the air is being pushed at like itself cuz that's

00:03:43.360 --> 00:03:50.000
just a terrible idea and makes no sense next up what we're going to do is have

00:03:47.480 --> 00:03:53.840
it all the air going up with two layers of fans we're going to have the bottom

00:03:51.640 --> 00:03:58.599
fans pushing air up through the rad and the top fans pushing pulling air up

00:03:55.959 --> 00:04:04.840
through the rat so let's try that one so fairly unsurprisingly with an ambient of

00:04:00.599 --> 00:04:07.599
18.7 De and a core temperature of 35°

00:04:04.840 --> 00:04:11.799
it's exactly the same as having the fans point the other direction so right now

00:04:10.120 --> 00:04:16.040
we have the fans pulling up through the rad for the ones that are on the top and

00:04:14.560 --> 00:04:19.919
we have the pants pushing up through the rad for the ones that are on the bottom

00:04:18.079 --> 00:04:23.840
now we're going to try single layer again but on the top which includes one

00:04:22.199 --> 00:04:28.560
of my favorite configurations but we'll do that one last so with the fans on top

00:04:26.320 --> 00:04:34.160
pushing down through the rad we got a temperature through the computer

00:04:29.720 --> 00:04:37.919
computer of 39° and an ambient of

00:04:34.160 --> 00:04:40.039
18.8 which is about 1° higher than when

00:04:37.919 --> 00:04:45.039
we started with the fans on the bottom in the same type of configuration um but

00:04:42.880 --> 00:04:49.639
also about 1 degree higher ambient so more or less the exact same result okay

00:04:47.600 --> 00:04:53.840
and as I expected last and definitely not least pulling up through the rad

00:04:52.039 --> 00:04:58.080
this is my favorite configuration and our favorite configuration here at lonus

00:04:55.479 --> 00:05:01.160
techtips because of the Dust Management Properties where it will put the Dust on

00:04:59.800 --> 00:05:05.479
the bottom of the radiator where it's very easy to take away instead of sandwiching it somewhere and making it

00:05:04.440 --> 00:05:10.240
very annoying cuz you have to go through the fans and all that crap it at an

00:05:07.720 --> 00:05:14.919
ambient of 18.9 which I would like to point out is almost one full degree

00:05:12.360 --> 00:05:20.479
higher than when we started reached about 39° on the core which is exactly

00:05:18.120 --> 00:05:24.160
one degree higher than the ones we were running when it started so it performs

00:05:22.199 --> 00:05:29.840
just as well as having the fans below the rad and is better for dust

00:05:26.120 --> 00:05:32.560
management a win in my opinion so as is

00:05:29.840 --> 00:05:37.800
seems to be with the workshop the conclusion is it doesn't really matter

00:05:34.720 --> 00:05:39.639
that much in terms of actual cooling

00:05:37.800 --> 00:05:44.080
unless you do something stupid like make them face each other and conflicting

00:05:41.600 --> 00:05:49.560
airflow paths and all that kind of stuff adding another set of fans can improve

00:05:46.600 --> 00:05:53.840
your cooling but not by a huge amount and probably not by an amount in my

00:05:51.800 --> 00:05:58.600
opinion that I would bother getting too more fans for your rad and adding that

00:05:56.919 --> 00:06:03.720
much thickness into the top of your case and having to deal with the them and all

00:06:00.080 --> 00:06:05.639
that kind of crap and last but not least

00:06:03.720 --> 00:06:11.039
I would like to reaffirm that in my opinion the best way to put the fans is

00:06:08.039 --> 00:06:12.880
pulling up through the rad with the fans

00:06:11.039 --> 00:06:17.880
on the top so that the dust will get caked onto the very bottom of the rad

00:06:15.840 --> 00:06:22.360
instead of having it Go in some other direction where the dust is going to get

00:06:19.400 --> 00:06:26.520
onto the fans themselves and onto the rad under where the fans are which is an

00:06:24.479 --> 00:06:32.000
extremely annoying place to clean it off of crunchy roll is a site created by

00:06:29.160 --> 00:06:35.400
anime fans for anime fans they off the most current episodes of new shows

00:06:33.520 --> 00:06:39.520

00:06:37.960 --> 00:06:43.960
have a large collection of the most popular anime series like Mobile Suit

00:06:41.520 --> 00:06:48.759
