00:00:07,520 --> 00:00:13,599
thinking about building your own pc but worried that it's going to be as tricky

4
00:00:11,519 --> 00:00:18,480
as luke skywalker's mission down the death star trench well fear not you may

5
00:00:16,320 --> 00:00:22,720
not have the spirit of obi-wan guiding you as you plug wires into headers not

6
00:00:20,640 --> 00:00:28,080
much bigger than a womp rat but you do have episode four of avoiding common pc

7
00:00:26,160 --> 00:00:30,800
building traps which i hope will give you some

8
00:00:29,279 --> 00:00:35,600
new hope first off while the empire made a huge

9
00:00:33,840 --> 00:00:41,600
mistake in connecting the thermal exhaust port to the main reactor in your

10
00:00:38,800 --> 00:00:46,320
case you want waste heat to exit your computer as directly as possible which

11
00:00:44,160 --> 00:00:50,399
is why you should pay close attention to fan orientation

12
00:00:47,920 --> 00:00:55,680
specifically if you're using more than two fans it's a good idea to create

13
00:00:53,120 --> 00:01:00,640
positive air pressure inside your case by using slightly more fans as intakes

14
00:00:58,879 --> 00:01:05,680
rather than exhaust this will force air out of your case

15
00:01:02,800 --> 00:01:10,400
more effectively reducing dust buildup as long as your case is filtered and it

16
00:01:08,400 --> 00:01:15,040
also potentially allows you to run your fans at lower speeds for a quieter

17
00:01:13,040 --> 00:01:20,080
computing experience otherwise having the same number of

18
00:01:17,280 --> 00:01:26,320
intakes and exhausts preferably with the ladder more towards the top rear of the

19
00:01:22,240 --> 00:01:27,840
case since heat rises is a good safe bet

20
00:01:26,320 --> 00:01:32,960
you can learn more about fan configuration and air pressure up here

21
00:01:30,960 --> 00:01:36,720
and while we're on the topic of thermals are you using a tower style air cooler

22
00:01:35,280 --> 00:01:41,840
for your CPU if so watch your hands while you're installing

23
00:01:39,600 --> 00:01:46,399
it or working anywhere near it such as if you're trying to insert a graphics

24
00:01:43,680 --> 00:01:51,759
card below it these air coolers use a lot of little fins to maximize the

25
00:01:49,360 --> 00:01:57,280
surface area that's available to cool down your processor but to achieve this

26
00:01:54,479 --> 00:02:01,360
the fins are often super thin meaning they can also be super sharp and you do

27
00:02:00,399 --> 00:02:07,520
not want monochromatic blood harshing your

28
00:02:04,640 --> 00:02:11,599
RGB vibes but let's say you've decided not to bother with that and you go

29
00:02:09,280 --> 00:02:16,319
straight to water cooling specifically a custom loop you can learn much more

30
00:02:13,520 --> 00:02:20,160
about custom water loops in this video one common trap for folks who are just

31
00:02:18,160 --> 00:02:24,480
beginning with liquid cooling though is that they might buy components made of

32
00:02:22,400 --> 00:02:30,640
different kinds of metal you see if you buy for example a copper

33
00:02:27,360 --> 00:02:32,959
CPU block but an aluminum radiator and

34
00:02:30,640 --> 00:02:38,879
put them in the same loop they'll eventually corrode due to chemical

35
00:02:35,760 --> 00:02:41,680
reactions that occur when you mix metals

36
00:02:38,879 --> 00:02:47,040
not only destroying your loop but also possibly your expensive electronics if

37
00:02:44,400 --> 00:02:52,480
water leaks out yikes leading us to a boring but incredibly

38
00:02:49,760 --> 00:02:58,000
important tip it seems like every other day we see a build with big money spent

39
00:02:55,280 --> 00:03:01,680
on expensive components of questionable utility

40
00:02:59,200 --> 00:03:05,599
and unlike our advice from the last episode to

41
00:03:03,280 --> 00:03:10,959
balance the build by avoiding doing things like pairing a 50 CPU with a 500

42
00:03:09,599 --> 00:03:15,840
graphics card some things are just colossal wastes of

43
00:03:13,680 --> 00:03:21,519
money regardless of how high-end the rest of your rig is like

44
00:03:17,680 --> 00:03:22,959
hard drive water blocks 300 sound cards

45
00:03:21,519 --> 00:03:27,760
at that point you should really just be getting an external dac and amp and

46
00:03:25,360 --> 00:03:31,440
gaming network cards which are little more than snake oil unless of course you

47
00:03:30,239 --> 00:03:37,840
really just want the thing for aesthetics finally no matter what kinds of exotic

48
00:03:35,519 --> 00:03:43,040
components you are or aren't using consider initially building your system

49
00:03:40,400 --> 00:03:46,560
outside of the case not only does this save you from the hassle of taking

50
00:03:44,959 --> 00:03:50,879
everything out if you have to troubleshoot a bad component it also

51
00:03:48,799 --> 00:03:56,959
allows you to more quickly isolate the defective part if your system won't boot

52
00:03:54,319 --> 00:04:01,439
so do you have any sage advice for new or veteran pc builders leave it in the

or if it's time for it to become one with the force

56
00:04:10,239 --> 00:04:17,519
