we all need to cool our computers and since you can't just Chuck them into an
ice bath we use fans to move hot air away from vital components but fans have
issues of their own they're loud and they wear out over time but there's
actually a type of fan out there that's super quiet and will probably last
longer than the rest of your PC they're called magnetic levitation or maglev
fans and yes they operate on the same Principle as those Ultra fast trains in
Japan and stuff you see every fan needs a bearing near its Center to hold the
fan shaft in place and allow it to spin in the proper direction and the way that
magnetic bearings work is really cool maglev bearings do not require any
physical contact between the fan shaft and the bearing itself instead magnets
both keep the fan balanced and calibrated in midair so it doesn't go
off axis and also make the fans spin with differences in magnetic polarity
very similar to how a maglev train is suspended off the tracks by magnetic
repulsion and polarity differences on the rail both push and pull the train
forward but unlike a train the big advantage of maglev fans isn't about
going at crazy speeds instead the fact
that the shaft doesn't make any physical contact with the bearing means there's
almost no friction most bearing types commonly found in computers involve
contact between the shaft and the bearing itself which creates both
unwanted noise as well as wear and tear common sleeve bearing and ball bearing
fans try to cut down on these issues by using oil lubricant But ultimately
friction and lubricant loss will get the better of these fans and they'll need to
be replaced at some point but since megala fans don't really have these
issues they can last a really long time Corsair one of the big manufacturers of
magular fans claims a 200 000 hour mean
time before failure yes that's nearly 23 years of continuous operation continuous
and I'm guessing you probably won't be using your next computer for quite that
long of course the lack of friction doesn't mean it'll last forever dust and
dirt can still damage the fan and the underlying electronics that make the fan
blades turn can also wear out over time but at the end of the day most users
won't have to worry about searching for a replacement fan within the lifespan of
the computer so that's just one last thing
the other big advantage of a maglev fan is the reduced noise output because the
moving parts of the fan aren't actually touching anything the only noise you'll
hear is the sound of the air moving through the fan blades meaning megala
fans can be nearly silent at lower RPMs and quieter than competing fan types
once you crank them up during a gaming session or editing session there's
another big advantage to Mega fans that you'll see immediately and will tell you
about it right after we thank you green for sponsoring this video ugreen's nexo
100 watt charger is a four in one device that has three USBC ports and a USB a

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
below so magma fans are fantastic we all get it but are there any disadvantages
it turns out there are actually are not really any trade-offs versus other fan
types in terms of performance and features but as you might imagine they
are among the most expensive computer fans available if you're looking for the
cheapest fans check out our video on the other bearing types but be careful as
one common type is not suitable for being mounted horizontally do you have
this found in your PC I don't know a couple of other caveats that don't involve price since magla fans are less
common than the other fan types it may be more difficult to find them in
exactly the aesthetic that you want for your build and also remember that maglev
fans typically don't give you a big increase in cooling performance above
the other fan types so while the long life and low noise are nice don't expect
them to magically make your temperatures plummet but hey there are other features
still make them a cool addition to your PC huh right sorry
