1
00:00:00,280 --> 00:00:06,759
do you really need that goopy gray weird

2
00:00:03,919 --> 00:00:11,519
smelling paste on your CPU can't we just sit our impressive looking heat sinks on

3
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

4
00:00:15,200 --> 00:00:21,160
many heat sinks don't sit flat against your CPU and in some cases with good

5
00:00:19,160 --> 00:00:27,039
reason but that might be for another video rather they're either concave or

6
00:00:24,560 --> 00:00:32,119
convex so there's a fair amount of space where your heat sink and processor

7
00:00:28,840 --> 00:00:34,440
aren't making prop contact also even

8
00:00:32,119 --> 00:00:39,120
though the top of your CPU or the bottom of your heat sink might look perfectly

9
00:00:36,440 --> 00:00:42,800
smooth even shiny in some cases they're actually rougher at the microscopic

10
00:00:40,760 --> 00:00:46,879
level than you might think and as a result they don't actually sit

11
00:00:44,399 --> 00:00:51,920
completely flush against each other this means that without thermal compound air

12
00:00:48,920 --> 00:00:56,199
pockets exist between your CPU and your

13
00:00:51,920 --> 00:00:58,320
heat sink so why is that a problem well

14
00:00:56,199 --> 00:01:02,840
it turns out that even though hot or cold air makes dramatic difference in

15
00:01:00,359 --> 00:01:07,040
how your body feels as the seasons change air is actually a very poor

16
00:01:05,040 --> 00:01:10,880
conductor of heat in general if you don't believe me try holding a steak an

17
00:01:08,880 --> 00:01:16,119
inch above a frying pan instead of placing it inside and let me know how

18
00:01:13,520 --> 00:01:20,000
that goes for you so thermal paste fills these would be air gaps so that your

19
00:01:18,040 --> 00:01:24,320
heat sink and CPU are touching more directly and the good stuff anyways is

20
00:01:22,799 --> 00:01:29,000
also made from special materials that help conduct heat properly so that it

21
00:01:26,400 --> 00:01:34,000
can go up into your heat sink so while you can use toothpaste as thermal

22
00:01:31,400 --> 00:01:38,119
compound to save money you probably really shouldn't for this to work best

23
00:01:36,399 --> 00:01:42,320
the conducting material in thermal paste is usually some sort of metal with more

24
00:01:40,680 --> 00:01:46,759
expensive varieties containing things like powdered silver and while this

25
00:01:44,719 --> 00:01:51,159
makes sense since metal conducts heat quite well it used to cause problems for

26
00:01:49,280 --> 00:01:56,159
novice Builders who put on too much thermal compound because metal Paste can

27
00:01:53,560 --> 00:02:01,640
also end up being electrically conductive oops fortunately it's less of

28
00:01:59,360 --> 00:02:05,000
an issue these days with higher quality compounds like Arctic Silver 5 managing

29
00:02:03,680 --> 00:02:10,119
to remain non-conductive in spite of using metal

30
00:02:08,280 --> 00:02:15,319
though you still need to keep it away from metal contacts and traces as it is

31
00:02:12,800 --> 00:02:18,480
mildly capacitive which can still be a problem but if you want to be really

32
00:02:17,040 --> 00:02:23,400
safe you can buy thermal paste that contains no metal at all these are

33
00:02:20,959 --> 00:02:27,840
typically made of ceramic though more Exotic Solutions that contain things

34
00:02:25,000 --> 00:02:32,280
like diamonds do exist although they sadly won't add a bling factor to your

35
00:02:30,000 --> 00:02:36,840
rig they will do a decent job of keeping your processor cool however the downside

36
00:02:34,519 --> 00:02:40,680
of these is that you typically won't get quite the same level of performance as

37
00:02:38,800 --> 00:02:46,239
you would with a more metallic based Pace but highquality Ceramics are not

38
00:02:43,239 --> 00:02:48,480
only cheaper they will also only set you

39
00:02:46,239 --> 00:02:54,040
back by a few degrees in most cases and are actually the best option for exotic

40
00:02:51,000 --> 00:02:56,400
Subzero cooling which you can check out

41
00:02:54,040 --> 00:03:01,640
here and of course if you want to avoid messes entirely you can get thermal pads

42
00:02:59,319 --> 00:03:05,280
usually just is made of silicone which just sits squished between your heat

43
00:03:03,360 --> 00:03:10,200
sink and whatever you're trying to cool you commonly see these on small graphics

44
00:03:07,519 --> 00:03:15,280
card components since there's no danger of leakage but since they can't get down

45
00:03:12,680 --> 00:03:20,360
into the micro crevices as well as paste performance won't be nearly as good so

46
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

47
00:03:23,519 --> 00:03:30,480
though make sure you aren't accidentally buying thermal adhesive these glues or

48
00:03:27,840 --> 00:03:34,920
epoxies permanently bond to two things together this stuff used to be somewhat

49
00:03:32,480 --> 00:03:39,000
common in certain PC components but has now been mostly relegated to smaller

50
00:03:37,280 --> 00:03:43,599
electronics that aren't meant to be taken apart nonetheless it's still easy

51
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

52
00:03:45,439 --> 00:03:51,760
stuck without a working CPU I'll show myself how it that was a

53
00:03:50,239 --> 00:03:56,159
little brutal if you're not a member of Dollar

54
00:03:54,079 --> 00:04:00,400
shap Club yet join today and get your first month of razors for free they

55
00:03:58,200 --> 00:04:03,799
deliver amazing razors directly to your door and membership means that you can

56
00:04:02,319 --> 00:04:08,280
probably afford to shave with a fresh blade anytime you want which is

57
00:04:05,760 --> 00:04:12,760
fantastic you'll get a first class shave when you use the executive blade without

58
00:04:10,640 --> 00:04:17,720
hurting your wallet and you can also use Dr Carver's shave butter using it with

59
00:04:15,040 --> 00:04:22,800
the executive blade uh creates a wonderfully smooth shave they ship to

60
00:04:20,479 --> 00:04:27,560
the US Canada on Australia so head over to dollarshaveclub.com Linus to give it

61
00:04:25,639 --> 00:04:32,080
a try for free if you guys like the video like it or dislike it if you you

62
00:04:29,840 --> 00:04:36,520
don't like it or whatever if you're like this topic sucked I have a good idea for
