00:00:07.600 --> 00:00:13.759
ever gotten all excited over your powerful new pc build then realized once

00:00:11.840 --> 00:00:18.000
you started gaming on it that it sounds like a miniature wind tunnel in your

00:00:15.519 --> 00:00:21.439
bedroom indeed excess computer noise has been an issue for a long time so it

00:00:19.520 --> 00:00:25.439
isn't surprising that these days just about every major case and cooling

00:00:23.279 --> 00:00:32.320
manufacturer including be quiet! who sponsored this video offers some kind of

00:00:28.000 --> 00:00:33.840
quiet series but what makes them quieter

00:00:32.320 --> 00:00:38.399
and what else can you do to cut down on noise let's start by looking at the

00:00:35.600 --> 00:00:43.040
cases themselves many cases marketed as low noise add some kind of dampening

00:00:40.640 --> 00:00:46.559
material to the inside usually foam the reason for this is pretty simple you

00:00:45.040 --> 00:00:51.039
know how an empty room with hardwood floors makes your voice echo

00:00:49.200 --> 00:00:55.520
when you say something but laying down some carpet has the opposite effect same

00:00:53.440 --> 00:00:59.520
principle softer surfaces have a microscopic structure that allows them

00:00:57.360 --> 00:01:04.640
to trap sound rather than reflecting it making foam a cost-effective and popular

00:01:02.160 --> 00:01:08.159
choice well-built quiet cases will also often feature vibration dampening

00:01:06.320 --> 00:01:11.840
features such as small rubber grommets that hold mechanical drives in place to

00:01:10.240 --> 00:01:16.000
keep them from transferring vibration to your case's plastic or metal frame of

00:01:14.080 --> 00:01:21.040
course you still need a way to push heat out of your case so oftentimes quiet

00:01:18.640 --> 00:01:25.439
cases will come with you guessed it quiet fans computer fans are equipped

00:01:23.520 --> 00:01:28.720
with a wide variety of different bearing types these are the little bits in the

00:01:27.200 --> 00:01:33.439
center of the fan that actually enable it to spin you can learn more about them

00:01:30.799 --> 00:01:37.439
here but here's a tldr common sleeve bearing fans are cheap for

00:01:35.680 --> 00:01:41.600
manufacturers and can be reasonably quiet when they are new the problem is

00:01:39.680 --> 00:01:46.240
that compared to ball bearing fans which are a bit more expensive and typically

00:01:43.600 --> 00:01:52.079
louder they tend to wear out much faster and any worn out fan is a loud fan

00:01:49.920 --> 00:01:55.040
trust me as you move up into higher end designs you can get to have your cake

00:01:54.000 --> 00:01:59.759
and eat some of it too rifle bearing fans share

00:01:57.840 --> 00:02:04.479
some design similarities with sleeves but they are better lubricated which

00:02:01.840 --> 00:02:08.319
increases their longevity moving further up the food chain we find fluid dynamic

00:02:06.719 --> 00:02:12.239
bearing fans that do a better job of keeping the lubricant between the fan

00:02:10.160 --> 00:02:17.360
and the seal using high pressure this cuts down on friction making them much

00:02:15.120 --> 00:02:20.800
quieter and finally you can even get magnetic bearings where the bearing

00:02:18.959 --> 00:02:25.200
doesn't even touch the body of the fan kind of like a maglev train which makes

00:02:22.720 --> 00:02:29.680
them insanely quiet but because those are also quite expensive you'll often

00:02:27.200 --> 00:02:33.920
see quiet cases designed to use fewer larger fans as they give you lots of

00:02:31.599 --> 00:02:37.360
airflow at lower rpms which helps them stay quieter than their smaller

00:02:35.200 --> 00:02:41.840
counterparts which leads us perfectly to another way to cut down on fan noise if

00:02:39.440 --> 00:02:46.239
a slower fan is quieter surely one that's off is even better some high

00:02:44.239 --> 00:02:50.319
efficiency power supplies feature a 0 RPM fan mode which means the fan won't

00:02:48.319 --> 00:02:54.239
spin up at all when the system is idle though it should be noted that once you

00:02:52.000 --> 00:02:59.040
fire up a game the fan will need to spin so zero RPM mode isn't an excuse for a

00:02:56.640 --> 00:03:02.720
manufacturer to cheap out on it the same is true for graphics cards which can

00:03:00.879 --> 00:03:07.200
have as many as three or four fans on them and be a huge source of noise under

00:03:04.879 --> 00:03:11.200
load so keep a lookout for gpus that are cooled well enough to not need the fans

00:03:09.200 --> 00:03:16.000
all the time some can even play basic games with the fans off

00:03:13.840 --> 00:03:19.599
crazy regardless of what kind of fan setup you have in your pc though keep an

00:03:17.920 --> 00:03:24.080
eye out for components that allow you to set custom fan curves some motherboards

00:03:22.080 --> 00:03:27.280
and cases include a fan controller so you won't be fighting a losing battle

00:03:25.519 --> 00:03:32.080
against a pc that thinks it knows better than you how much cooling it needs

00:03:30.159 --> 00:03:35.840
yeah right but what if you simply don't want to mess around with more fans than

00:03:33.599 --> 00:03:40.400
you absolutely have to well it is possible to buy passive heatsinks for

00:03:37.680 --> 00:03:44.239
your CPU and GPU that you don't strap fans to and therefore are totally silent

00:03:42.560 --> 00:03:49.200
but not only can they limit your overclocking potential they can also be

00:03:46.319 --> 00:03:52.400
really bulky and unsightly so you may want to pass on a case with a window if

00:03:51.120 --> 00:03:57.439
you go this route root a more popular option is to liquid cool

00:03:55.519 --> 00:04:02.239
your rig and simply place water blocks on your CPU and graphics card combined

00:03:59.680 --> 00:04:05.920
with a radiator with quiet bearing fans the only thing to watch for here is the

00:04:04.000 --> 00:04:09.680
quality of your pump so make sure to thoroughly check reviews as just like

00:04:07.680 --> 00:04:14.560
cheap fans cheap pumps can wear out quickly and get very noisy and finally

00:04:12.879 --> 00:04:18.639
keep in mind that even if your cooling system is quieter than a church mouse

00:04:16.959 --> 00:04:22.720
it's still important to pick components like power supplies and graphics cards

00:04:20.320 --> 00:04:26.240
that won't suffer from coil whine or electrical noise so make sure to read

00:04:24.639 --> 00:04:30.320
reviews and see if a certain model you're looking at is susceptible to it

00:04:28.320 --> 00:04:34.000
otherwise that high-pitched distraction might totally wipe out any acoustic

00:04:32.240 --> 00:04:39.040
benefits you got from spending your entire tax refund on an RGB nickel

00:04:37.040 --> 00:04:43.199
plated water block the be quiet! silent base 601 delivers

00:04:41.280 --> 00:04:47.600
