1
00:00:00,240 --> 00:00:05,200
first of all whatever the uh lightning

2
00:00:03,360 --> 00:00:10,360
bolt shaped scar on my forehead might indicate water cooling is not magic it

3
00:00:08,080 --> 00:00:15,320
makes your PC's temperatures lower but it doesn't make your components output

4
00:00:12,519 --> 00:00:22,000
less heat that means that an air cooled CPU that runs at 80° or a water cooled

5
00:00:18,760 --> 00:00:24,560
CPU that runs at 60° are both actually

6
00:00:22,000 --> 00:00:29,519
kicking the same amount of heat out into the room the temperature Improvement on

7
00:00:27,400 --> 00:00:35,719
them comes from water's ability to move Heat away from the CPU to a large heat

8
00:00:32,800 --> 00:00:40,320
exchanger much faster than air this heat exchanger is called a radiator and its

9
00:00:38,559 --> 00:00:45,440
job is to dissipate the heat that your liquid coolant brings to it to the

10
00:00:42,800 --> 00:00:50,399
surrounding air sounds great right so now you want water cooling question

11
00:00:47,480 --> 00:00:55,960
number one I get from prospective water cooling owners is what sized radiator

12
00:00:53,079 --> 00:01:00,039
should I use and the answer is usually the biggest one you can with modern

13
00:00:58,079 --> 00:01:04,640
pumps and CPU blocks as close and performance as they are the size and

14
00:01:02,480 --> 00:01:09,880
type of radiator will often have the largest impact on the system's overall

15
00:01:06,640 --> 00:01:12,040
ability to dissipate heat now most case

16
00:01:09,880 --> 00:01:16,040
manufacturers are actually listing radiator compatibility on their websites

17
00:01:14,040 --> 00:01:21,240
these days so life has gotten a little simpler here but you've still got some

18
00:01:18,320 --> 00:01:26,240
work to do as they don't suggest exactly which product to use because there are

19
00:01:22,920 --> 00:01:28,720
just so many choices let's break them

20
00:01:26,240 --> 00:01:36,040
down a little bit most pre-filled liquid cooling systems use either 120 mm or 140

21
00:01:33,360 --> 00:01:40,680
mm fans and are available in either single or dual fan configurations now

22
00:01:39,640 --> 00:01:47,119
just to make sure you were paying attention which of those four options do

23
00:01:43,000 --> 00:01:49,399
you think is best yes the Dual 140 mm

24
00:01:47,119 --> 00:01:53,560
fan radiator will outperform the other solutions for a couple of reasons by

25
00:01:51,640 --> 00:01:59,079
presenting the fans on your radiator a much larger surface area to cool you're

26
00:01:55,840 --> 00:02:00,520
allowing them to spin slower and deliver

27
00:01:59,079 --> 00:02:05,439
the same performance giving you a quieter system or spin at the same speed

28
00:02:04,000 --> 00:02:10,239
that means more air flow through the fins of the radiator giving you a cooler

29
00:02:08,080 --> 00:02:15,519
system but let's say your case doesn't support 140 mm fans and you still want

30
00:02:13,760 --> 00:02:21,519
more surface area and more heat dissipation good news you can make your

31
00:02:17,959 --> 00:02:23,920
radiator thicker or you can increase the

32
00:02:21,519 --> 00:02:28,000
density of the fins that are folded between the water tubes and the rad by

33
00:02:26,120 --> 00:02:32,239
folding them Tighter and closer to each other this approach does have

34
00:02:30,040 --> 00:02:36,800
disadvantage though making the radiator thicker may cause interference with

35
00:02:34,319 --> 00:02:40,720
other nearby components in some cases and both of these things will require

36
00:02:38,640 --> 00:02:44,599
you to use very high static pressure fans I mean it's generally better to use

37
00:02:43,200 --> 00:02:49,760
static pressure optimized fans on radiators and heat sinks in as a whole

38
00:02:47,840 --> 00:02:54,239
but for dense ones it can have an enormous impact on performance now most

39
00:02:52,440 --> 00:02:59,040
of what we talked about so far is for folks who are buying pre-filled liquid

40
00:02:56,000 --> 00:03:01,440
coolers or custom ones but these last

41
00:02:59,040 --> 00:03:05,920
considerations are mostly for the DIY folks or anyone who bought an expandable

42
00:03:04,120 --> 00:03:10,680
pre-filled like The Cooler Master glacer 240 L some custom builds are going to

43
00:03:08,760 --> 00:03:18,519
require you to find a radiator that has fitting ports on the top or on you know

44
00:03:15,200 --> 00:03:20,080
opposing sides or even on opposing ends

45
00:03:18,519 --> 00:03:23,920
those are out there but they're more of a specialty item for people who are

46
00:03:21,680 --> 00:03:27,640
trying to achieve a very specific tubing layout in their build another thing to

47
00:03:25,840 --> 00:03:31,840
watch out for though it's much less common these days is the material the

48
00:03:29,799 --> 00:03:35,879
radiator is made out of in a water cooling Loop if you're not using

49
00:03:33,760 --> 00:03:39,680
anti-corrosive additives you want to avoid mixing Metals unnecessarily

50
00:03:37,959 --> 00:03:43,920
wherever the water makes contact with them brass and copper in the same Loop

51
00:03:41,920 --> 00:03:48,120
so copper in your block and Brass in your radiator tubes are okay and most

52
00:03:46,519 --> 00:03:52,000
radiators are made of these materials but I do suggest using an appropriate

53
00:03:49,879 --> 00:03:56,360
additive if you want to use an aluminum radiator with that said if the fins in

54
00:03:54,360 --> 00:04:01,120
between are made of aluminum that's just fine speaking of appropriate additives I

55
00:03:58,560 --> 00:04:04,680
guess I'll add this sponsor message huge props to Cooler Master for sponsoring
