00:00:00,000 --> 00:00:06,720
we all need to cool our computers and since you can't just Chuck them into an

2
00:00:04,319 --> 00:00:11,940
ice bath we use fans to move hot air away from vital components but fans have

3
00:00:09,120 --> 00:00:16,859
issues of their own they're loud and they wear out over time but there's

4
00:00:14,519 --> 00:00:21,359
actually a type of fan out there that's super quiet and will probably last

5
00:00:18,900 --> 00:00:26,220
longer than the rest of your PC they're called magnetic levitation or maglev

6
00:00:23,699 --> 00:00:31,019
fans and yes they operate on the same Principle as those Ultra fast trains in

7
00:00:28,439 --> 00:00:35,340
Japan and stuff you see every fan needs a bearing near its Center to hold the

8
00:00:33,120 --> 00:00:39,600
fan shaft in place and allow it to spin in the proper direction and the way that

9
00:00:37,260 --> 00:00:44,280
magnetic bearings work is really cool maglev bearings do not require any

10
00:00:42,059 --> 00:00:48,899
physical contact between the fan shaft and the bearing itself instead magnets

11
00:00:47,100 --> 00:00:53,340
both keep the fan balanced and calibrated in midair so it doesn't go

12
00:00:50,820 --> 00:00:57,660
off axis and also make the fans spin with differences in magnetic polarity

13
00:00:55,440 --> 00:01:01,800
very similar to how a maglev train is suspended off the tracks by magnetic

14
00:00:59,579 --> 00:01:05,880
repulsion and polarity differences on the rail both push and pull the train

15
00:01:03,600 --> 00:01:11,280
forward but unlike a train the big advantage of maglev fans isn't about

16
00:01:08,040 --> 00:01:12,900
going at crazy speeds instead the fact

17
00:01:11,280 --> 00:01:17,640
that the shaft doesn't make any physical contact with the bearing means there's

18
00:01:14,880 --> 00:01:20,939
almost no friction most bearing types commonly found in computers involve

19
00:01:19,200 --> 00:01:25,439
contact between the shaft and the bearing itself which creates both

20
00:01:22,560 --> 00:01:29,880
unwanted noise as well as wear and tear common sleeve bearing and ball bearing

21
00:01:27,900 --> 00:01:35,159
fans try to cut down on these issues by using oil lubricant But ultimately

22
00:01:32,340 --> 00:01:38,880
friction and lubricant loss will get the better of these fans and they'll need to

23
00:01:37,020 --> 00:01:43,079
be replaced at some point but since megala fans don't really have these

24
00:01:40,740 --> 00:01:48,420
issues they can last a really long time Corsair one of the big manufacturers of

25
00:01:45,240 --> 00:01:51,240
magular fans claims a 200 000 hour mean

26
00:01:48,420 --> 00:01:55,860
time before failure yes that's nearly 23 years of continuous operation continuous

27
00:01:53,700 --> 00:01:59,939
and I'm guessing you probably won't be using your next computer for quite that

28
00:01:57,780 --> 00:02:05,460
long of course the lack of friction doesn't mean it'll last forever dust and

29
00:02:03,000 --> 00:02:09,780
dirt can still damage the fan and the underlying electronics that make the fan

30
00:02:07,320 --> 00:02:13,620
blades turn can also wear out over time but at the end of the day most users

31
00:02:12,120 --> 00:02:17,400
won't have to worry about searching for a replacement fan within the lifespan of

32
00:02:15,959 --> 00:02:22,260
the computer so that's just one last thing

33
00:02:19,920 --> 00:02:26,520
the other big advantage of a maglev fan is the reduced noise output because the

34
00:02:25,020 --> 00:02:30,300
moving parts of the fan aren't actually touching anything the only noise you'll

35
00:02:28,379 --> 00:02:35,099
hear is the sound of the air moving through the fan blades meaning megala

36
00:02:32,220 --> 00:02:39,000
fans can be nearly silent at lower RPMs and quieter than competing fan types

37
00:02:37,200 --> 00:02:42,000
once you crank them up during a gaming session or editing session there's

38
00:02:40,260 --> 00:02:45,720
another big advantage to Mega fans that you'll see immediately and will tell you

39
00:02:43,980 --> 00:02:50,040
about it right after we thank you green for sponsoring this video ugreen's nexo

40
00:02:48,060 --> 00:02:54,780
100 watt charger is a four in one device that has three USBC ports and a USB a

41
00:02:52,560 --> 00:02:58,440
port that supplies up to 100 watts of power with that much power you can

42
00:02:56,519 --> 00:03:04,200
easily charge your phone tablet laptop all at the same time you can charge your

43
00:03:00,840 --> 00:03:06,660
iPhone 13 to 60 in 30 minutes or fully

charge your 16-inch MacBook Pro in under just an hour and a half with its

45
00:03:08,400 --> 00:03:13,500
foldable prongs the charger is still super travel friendly and it fits in the

palm of your hand so get your ugreen nexo 100 watt charger today at the links

47
00:03:16,019 --> 00:03:23,640
below so magma fans are fantastic we all get it but are there any disadvantages

48
00:03:20,940 --> 00:03:27,540
it turns out there are actually are not really any trade-offs versus other fan

49
00:03:25,800 --> 00:03:31,680
types in terms of performance and features but as you might imagine they

50
00:03:29,879 --> 00:03:36,300
are among the most expensive computer fans available if you're looking for the

51
00:03:34,019 --> 00:03:41,099
cheapest fans check out our video on the other bearing types but be careful as

52
00:03:38,700 --> 00:03:45,000
one common type is not suitable for being mounted horizontally do you have

53
00:03:43,200 --> 00:03:50,099
this found in your PC I don't know a couple of other caveats that don't involve price since magla fans are less

54
00:03:48,299 --> 00:03:53,459
common than the other fan types it may be more difficult to find them in

55
00:03:51,720 --> 00:03:57,540
exactly the aesthetic that you want for your build and also remember that maglev

56
00:03:55,680 --> 00:04:01,440
fans typically don't give you a big increase in cooling performance above

57
00:03:59,879 --> 00:04:05,400
the other fan types so while the long life and low noise are nice don't expect

58
00:04:03,780 --> 00:04:09,599
them to magically make your temperatures plummet but hey there are other features

59
00:04:07,920 --> 00:04:14,879
still make them a cool addition to your PC huh right sorry

60
00:04:12,900 --> 00:04:17,940
