00:00:00.320 --> 00:00:05.359
this is a question i've been asked a hundred times and based on a quick

00:00:03.760 --> 00:00:10.639
google search it looks like there are quite a few other folks who want the

00:00:07.279 --> 00:00:12.160
answer how hot can my pc run before it's

00:00:10.639 --> 00:00:16.240
not safe anymore okay well let's start with why you would

00:00:13.840 --> 00:00:20.080
care how hot it runs on lots of reasons high temperatures can cause all kinds of

00:00:18.160 --> 00:00:24.720
stuff in semiconductors it increases the electrical resistance

00:00:22.160 --> 00:00:28.480
reducing efficiency it can speed up the degradation of electrical pathways

00:00:26.400 --> 00:00:33.040
within the component allowing errors that cause data corruption and it can

00:00:30.560 --> 00:00:38.480
even if the proper safeguards weren't in place caused the low temperature solder

00:00:35.840 --> 00:00:41.280
that is sometimes used to completely melt

00:00:39.360 --> 00:00:44.399
alrighty then that's very scary can you give me the answer now Linus well hold

00:00:43.120 --> 00:00:48.160
on let's start with some information from the websites of a couple of

00:00:46.160 --> 00:00:52.559
computer hardware manufacturers you may have heard of the t-junction temperature

00:00:50.480 --> 00:00:58.320
the point at which it will turn down its own speed to preserve its life for the

00:00:54.640 --> 00:01:00.800
Intel core i7 4770k CPU is 105 degrees

00:00:58.320 --> 00:01:06.320
celsius the out of the box standard operating temperature of 95 degrees

00:01:02.960 --> 00:01:09.600
celsius for AMD's r9 290x graphics card

00:01:06.320 --> 00:01:12.000
is to quote AMD perfectly safe

00:01:09.600 --> 00:01:17.200
while powered on a wd red hard drive can operate anywhere from zero to 70 degrees

00:01:15.439 --> 00:01:23.119
which in their testing produces no unrecoverable errors and a gtx 780 ti

00:01:20.320 --> 00:01:26.479
ships at an 80 degree maximum and NVIDIA theoretically allows up to 95 degrees

00:01:25.119 --> 00:01:31.840
but we found that they actually limit it to around 86 degrees celsius so those

00:01:29.040 --> 00:01:36.000
are super scary high temperatures Linus my friend said it should be lower are

00:01:33.600 --> 00:01:40.000
they misinformed if it says it's okay directly on the manufacturer's website

00:01:37.840 --> 00:01:43.680
why is there so much confusion out there about this because it's not quite that

00:01:42.640 --> 00:01:47.840
simple unlike the engine in your car which uses

00:01:45.759 --> 00:01:53.520
a thermostat to maintain itself within a very narrow range usually with between

00:01:50.000 --> 00:01:56.000
90 to 100 degrees celsius most pc parts

00:01:53.520 --> 00:01:59.840
don't have moving parts that rely on tight manufacturing tolerances and high

00:01:58.240 --> 00:02:04.640
performance lubricants to keep them functioning so they don't really have an

00:02:02.159 --> 00:02:09.599
optimal operating temperature that means that while the hard drive with moving

00:02:06.960 --> 00:02:14.560
parts specified a maximum temperature for the other stuff a maximum is

00:02:12.000 --> 00:02:18.400
specified and a minimum is not because you can pretty much run it as low as you

00:02:16.480 --> 00:02:23.440
want and it'll be happier than a pig in split

00:02:20.160 --> 00:02:25.680
with that said lower is better if you're

00:02:23.440 --> 00:02:29.280
taking the appropriate precautions for most people you're not going to want

00:02:27.280 --> 00:02:33.440
your temperatures to drop any lower than ambient or the temperature of the

00:02:31.280 --> 00:02:37.760
surrounding air because below that temperature water droplets forming on

00:02:35.760 --> 00:02:42.640
your components due to condensation becomes a major concern water is worse

00:02:40.800 --> 00:02:46.720
for your hardware than high temperatures so here's the summary first check out

00:02:44.480 --> 00:02:50.080
the manufacturer's product page then take that information with a grain of

00:02:48.640 --> 00:02:56.319
salt if you're one of those people who believes in taking really good care of your stuff and you want to be sure that

00:02:53.920 --> 00:03:00.000
your hardware will last and be reliable keep in mind that the way manufacturers

00:02:58.560 --> 00:03:04.640
rate their products is based on the way they expect most people will actually

00:03:02.159 --> 00:03:09.440
use them they're not expecting you to still be using that CPU graphics card or

00:03:07.120 --> 00:03:12.959
hard drive in 10 years time and they certainly aren't giving you a warranty

00:03:10.879 --> 00:03:17.200
that lasts that long so they build some buffer into the numbers but they don't

00:03:14.720 --> 00:03:21.680
worry about those fringe cases too much so for added assurance take their number

00:03:19.599 --> 00:03:25.920
and build in your own buffer that makes you feel comfortable speaking of fringe

00:03:23.840 --> 00:03:30.799
cases the people who think trekking to the store and finding the last employee

00:03:28.959 --> 00:03:34.080
who actually still works on the sales floor of a grocery and drug chain to

00:03:32.560 --> 00:03:38.480
unlock a cage so you can spend twenty dollars on a package of freaking razors only to burn through them and realize

00:03:37.280 --> 00:03:42.959
that now you have to do it all over again the preceding run on time this was

machete-wielding man throwing a box that was presumably a man in a bear costume

00:03:55.280 --> 00:04:00.959
but could also be a bear who ate a person and then took over control of the bear from the inside and applied for a

00:03:59.599 --> 00:04:04.000
job at a pretty cool company that ships bathroom supplies to their thousands of

00:04:02.640 --> 00:04:08.879
