00:00:00.280 --> 00:00:06.759
do you really need that goopy gray weird

00:00:03.919 --> 00:00:11.519
smelling paste on your CPU can't we just sit our impressive looking heat sinks on

00:00:09.040 --> 00:00:16.960
top of our processors and be done with it no not even remotely and here's why

00:00:15.200 --> 00:00:21.160
many heat sinks don't sit flat against your CPU and in some cases with good

00:00:19.160 --> 00:00:27.039
reason but that might be for another video rather they're either concave or

00:00:24.560 --> 00:00:32.119
convex so there's a fair amount of space where your heat sink and processor

00:00:28.840 --> 00:00:34.440
aren't making prop contact also even

00:00:32.119 --> 00:00:39.120
though the top of your CPU or the bottom of your heat sink might look perfectly

00:00:36.440 --> 00:00:42.800
smooth even shiny in some cases they're actually rougher at the microscopic

00:00:40.760 --> 00:00:46.879
level than you might think and as a result they don't actually sit

00:00:44.399 --> 00:00:51.920
completely flush against each other this means that without thermal compound air

00:00:48.920 --> 00:00:56.199
pockets exist between your CPU and your

00:00:51.920 --> 00:00:58.320
heat sink so why is that a problem well

00:00:56.199 --> 00:01:02.840
it turns out that even though hot or cold air makes dramatic difference in

00:01:00.359 --> 00:01:07.040
how your body feels as the seasons change air is actually a very poor

00:01:05.040 --> 00:01:10.880
conductor of heat in general if you don't believe me try holding a steak an

00:01:08.880 --> 00:01:16.119
inch above a frying pan instead of placing it inside and let me know how

00:01:13.520 --> 00:01:20.000
that goes for you so thermal paste fills these would be air gaps so that your

00:01:18.040 --> 00:01:24.320
heat sink and CPU are touching more directly and the good stuff anyways is

00:01:22.799 --> 00:01:29.000
also made from special materials that help conduct heat properly so that it

00:01:26.400 --> 00:01:34.000
can go up into your heat sink so while you can use toothpaste as thermal

00:01:31.400 --> 00:01:38.119
compound to save money you probably really shouldn't for this to work best

00:01:36.399 --> 00:01:42.320
the conducting material in thermal paste is usually some sort of metal with more

00:01:40.680 --> 00:01:46.759
expensive varieties containing things like powdered silver and while this

00:01:44.719 --> 00:01:51.159
makes sense since metal conducts heat quite well it used to cause problems for

00:01:49.280 --> 00:01:56.159
novice Builders who put on too much thermal compound because metal Paste can

00:01:53.560 --> 00:02:01.640
also end up being electrically conductive oops fortunately it's less of

00:01:59.360 --> 00:02:05.000
an issue these days with higher quality compounds like Arctic Silver 5 managing

00:02:03.680 --> 00:02:10.119
to remain non-conductive in spite of using metal

00:02:08.280 --> 00:02:15.319
though you still need to keep it away from metal contacts and traces as it is

00:02:12.800 --> 00:02:18.480
mildly capacitive which can still be a problem but if you want to be really

00:02:17.040 --> 00:02:23.400
safe you can buy thermal paste that contains no metal at all these are

00:02:20.959 --> 00:02:27.840
typically made of ceramic though more Exotic Solutions that contain things

00:02:25.000 --> 00:02:32.280
like diamonds do exist although they sadly won't add a bling factor to your

00:02:30.000 --> 00:02:36.840
rig they will do a decent job of keeping your processor cool however the downside

00:02:34.519 --> 00:02:40.680
of these is that you typically won't get quite the same level of performance as

00:02:38.800 --> 00:02:46.239
you would with a more metallic based Pace but highquality Ceramics are not

00:02:43.239 --> 00:02:48.480
only cheaper they will also only set you

00:02:46.239 --> 00:02:54.040
back by a few degrees in most cases and are actually the best option for exotic

00:02:51.000 --> 00:02:56.400
Subzero cooling which you can check out

00:02:54.040 --> 00:03:01.640
here and of course if you want to avoid messes entirely you can get thermal pads

00:02:59.319 --> 00:03:05.280
usually just is made of silicone which just sits squished between your heat

00:03:03.360 --> 00:03:10.200
sink and whatever you're trying to cool you commonly see these on small graphics

00:03:07.519 --> 00:03:15.280
card components since there's no danger of leakage but since they can't get down

00:03:12.680 --> 00:03:20.360
into the micro crevices as well as paste performance won't be nearly as good so

00:03:17.560 --> 00:03:25.120
you don't see them on CPUs or the actual specific GPU very often whatever you do

00:03:23.519 --> 00:03:30.480
though make sure you aren't accidentally buying thermal adhesive these glues or

00:03:27.840 --> 00:03:34.920
epoxies permanently bond to two things together this stuff used to be somewhat

00:03:32.480 --> 00:03:39.000
common in certain PC components but has now been mostly relegated to smaller

00:03:37.280 --> 00:03:43.599
electronics that aren't meant to be taken apart nonetheless it's still easy

00:03:41.640 --> 00:03:47.680
to buy so make sure you're getting the right stuff if you don't want to end up

00:03:45.439 --> 00:03:51.760
stuck without a working CPU I'll show myself how it that was a

00:03:50.239 --> 00:03:56.159
little brutal if you're not a member of Dollar

00:03:54.079 --> 00:04:00.400

don't like it or whatever if you're like this topic sucked I have a good idea for

00:04:33.720 --> 00:04:39.639
