EDF Sound Comparison 12 Blade VS 5 Blade

[@jantjehd]

Nothing compared to my ps4

[@uvuvvweossas9481]

jantjehd STFU

[@nicevideochannel6583]

haahah

[@HoweDoYouDo1999]

Make sure it don’t blow up😂😂😂😂. The last thing Sony intended for was a bomb😂😂. Unless the gameplay was really explosive

[@wombatau]

Hahaha yes correct

[@tahayt6142]

Ps4 trash

[@HurricaneCity4000]

I want this is as my CPU cooler

[@legitscoper3259]

I actually have 4x San Ace 80 Fans wich have an (idk the exact amount) but ENORMOUSLY high static air pressure, and air flow ... but if i turn up the settings... my PC (Self build) becomes an Rollce Royce Axial compressor Engine... but my CPU never gets hotter than 50°C ... even with an outside temp of 35°C

[@gamingentity7170]

it will blow all your components 😂😂

[@mr.headshot6980]

Hahaha

[@Velo1010]

It’s doable.

[@mohdbadrulhisyambadrulhisy353]

Hahahaha

[@raypilot9958]

the 12 blade looks and sounds real

[@nicevideochannel6583]

Yes thats correct :)

[@hichamtribak1944]

how much they cost each? and how many volts? i guess more than 12v. no?

[@nicevideochannel6583]

In this video, they are powered with 7.2V Battery .... But actually Can go upto 12V

[@crackedemerald4930]

@Jake Heke the props are paid actors!

[@zoidenvoid]

Dylan Livingston whoosh

[@chrisbovee7018]

so you hear more of the motor/air chopping with fewer blades, you hear more of the airflow with more blades.

[@nicevideochannel6583]

Yes , I love sound of 12 Blades feels like real Turbo Jets ...

[@ΑΡΗΣΚΟΡΝΑΡΑΚΗΣ]

Nice Video Channel with 22 blades?

[@mohdaliffbusrah2066]

12 blade causes more bernoulli effect

[@thondupandrugtsang]

The twelve blade does sound more real like a plane.

[@Camarc64]

Wow, the 12 bladed one sounds fantastic !!!! Great :)

[@teravolt6113]

More blades tend to make a higher pitched noise. Saw this on a bus HVAC system equipped with 5 condenser fans on the roof unit. Earlier versions of the roof unit have 3 bladed fans, later ones 7 bladed fans. The former give way to a bass sound when running. The latter are pretty silent instead.

[@coriscotupi]

Cut the screws hanging into the flow.

[@nicevideochannel6583]

thinking to do that soon ...

[@GregoryBrown-fe5js]

12 blade sounds more authentic

[@adeeponionbrah]

Gregory Brown *

[@calebsherman886]

These are real EDF sounds, what do you mean?

[@MegaTechpc]

Caleb Sherman You know what he means. Sounds more like a real jet engine. Don't be pedantic.

[@milesr23]

I would love to see the same demonstration with an SPL meter to give a representation of the overall difference in broadband SPL between the two.

[@PetrincicBrosRC]

Very nice. I love EDF units. Oh yeah... Thanks for posting and greetings from Slovenia, Pilot Robert

[@nicevideochannel6583]

thankss dear Robert :D

[@jessiecabiso6802]

Robert Petrinčič

[@PetrincicBrosRC]

Oh yeah...

[@galaxyofgames5724]

Robert Petrinčič go

[@PetrincicBrosRC]

Iam going...

[@mohammadhmz5852]

Aaahhh that 12 blades really make music in my ears..

[@rcaviator8408]

Wow nice i think the 12 blade sounds much nicer than the 5 blade, it sounds a lot more realistic for a commercial liner if you were going to use it that way.

[@carmelpule6954]

They are both great machines, but the 12 bladed one is just a little ahead of the other. Very nice workmanship and the enclosure is so elegant . Congratulations.

[@nicevideochannel6583]

Thanks mate ....

[@Kopiko648]

I really like those sounds

[@nicevideochannel6583]

thanks dear ... I loved it too :)

[@daus7018]

Me too

[@joshhayl7459]

A substantial change in sound could very well be owing to the fact that the duct with the 12 bladed fan is mounted in a secondary enclosure, which could dampen high frequency resonance, as well as the screws protruding into the Chamber of the duct which would impede airflow and by that resistance change the overall tone. You also need to know how much current the motor is drawing and the decibel level at a given RPM, Even varying the finger pressure as you hold it in your hand could make a substantial difference in the resulting sound, so they both need to be in identical mounts/clamps of some manner. It's not really a fair (scientifically-empirical) comparison unless EVERYTHING (including the room that the test is taking place in) is identical, with the exception of the fan-blades.

[@jumpvelocity3953]

Which would be near impossible.

[@daviddavids2884]

thanks for posting. imo, it's great that there are now some relatively quiet edfs on the market. btw - 64mm is a 3s size, NOT 2s. unless the motors had, unheard of, kv, these edfs never reached reached nominal rpm. cheers

[@nicevideochannel6583]

yess at the time of recording my 3S went bad ... So i left with 2S option :)

[@nicevideochannel6583]

there is also video available High Speed run that is on 3S same fan

[@patprop74]

00:34 Damm i thought you were going to stick your finger in it loll

[@nicevideochannel6583]

Hahaha :))

[@n3on_face659]

00:33 :)

[@shutdahellup69420]

same i was like, are you insane?😂

[@niteshpant1974]

The sound/Noice is depend on the design of Blades and the pich both are totally different design so the sound id different but the 12 blades fan is made very accurate and precise so it has low noise.....Very clear.

[@laseonestar]

Awesome sounds the 12 blades made thx for the view. All the best Denmark

[@nicevideochannel6583]

Thanks for watching ...

[@laseonestar]

Nice Video Channel the pleasure was all mine ;-)

[@jockellis]

Guess I’m so old I couldn’t which was louder. They were different, though.

[@nicevideochannel6583]

I like your comments :)))

[@Misscarverfan1212]

I found out that these 12 blade fans are not good for hand launch takeoffs due to their tendency to stall ( blades on the impeller ) causing a significant decrease in thrust. The more conventional 5 blade impellers have better hand launch performance. When the 12 blade spools to 100% at a stand still, as in a hand launch situation, the impeller is trying to push out more air than can be efficiently pulled in from the usually narrow intakes - this causes the blades to stall. This effect can actually be seen by hooking your model to a scale, bringing the thrust from 0 - 100%, and seeing a drop in thrust when approaching 100%, this is while the model is in a static position. Cutting cheater holes in the body, or enlarging the intakes can remediate some of this problem.

[@nicevideochannel6583]

Yes, the 5 Blade gives more thrust because of more space maybe.

[@tjacksondolph4026]

sounded like the 12 blade produced more thrust with the same power input

[@lil_casperr3922]

Finger vs.......

[@G56AG]

The 12 blade SOUNDS much more authentic, to make any real sense of it we would need a thrust comparison also.

[@endretolnai]

very good thing , the bearin should be magnetic...then the noise would be even lower. thanks for the vid.

[@wolfgangreichl3361]

My thought too. At least with the five-blader I guess all you hear are the bearings. I assume for the same power output it has to turn higher.

[@scottmarshall6766]

The sheet metal screws hanging out in the flow aren't doing the 12 blade any good either in thrust or sound. Better to use pan head (or even better flat head) machine screws installed from the inside and put the nuts on the outside.

[@nicevideochannel6583]

Yes, I 100% agree ... But its more prominent in video ..

[@rcaviator8408]

Or if you had a shop, just cut those points down so they're not doing any harm to thrust.

[@mikev2116]

Yes true but not the point.

[@Justwantahover]

Which one is more efficient for thrust?

[@scottmarshall6766]

All else being equal (proper motor matching etc) the 12 blade would win the efficiency contest.

[@bryankwong-6091]

I like the one with 12 blades because the sound is a lot quieter than 5 blades

[@abaskamal]

Really expected the 12blade to be noisier than the 5, but no...I'm surprised.

[@nuddin99]

Abas Kamal well the more blades added, the slower the fan has to spin to generate the same amount of airflow.

[@737Garrus]

Absolutely 12-bladed variant!

[@mikegeorge5473]

I just ordered two 12 bladed fans for my 64mm A-10 from Freewing...not sure if it will give me a performance upgrade or not, but the sound is worth it

[@nicevideochannel6583]

Its only sound upgrade ... :)

[@Audunforgard]

12 bladed powerhouse! I was thinking how one could make it go silent, and just "Dude, it a motor!, Motors make sound!

[@nicevideochannel6583]

:))

[@MegaControltv]

Suena genial la edf de 12 blades !!

[@goriverman]

12 blade Sounds great. No contest

[@nicevideochannel6583]

Thats correct :D ...

[@varsity2845]

That 12 blade legit sounds like a real airliner lol

[@zanehopefz6hundred761]

Wow... 12 blade is so quite! I need a few of them haha

[@nicevideochannel6583]

Hahah :)

[@osamaansari6738]

what is the maximum rpm of the both fans

[@bobbyflowers4859]

15 seconds on each would have gotten the point across.

[@k2229]

Challenge for jet engine manufacturers. Trying to make them quiet.

[@chuckthebull]

12 blade seems to at least sound like it moves more air. would have also been cool to see some thrust figures..even just pulling a scale..

[@mauronavarro3209]

One of these on my pc will make fly in gaming

[@thomasrose6962]

the 5 blade can be tweaked to equal the 12 at higher rpm as far as thrust and noise imho the motor soumded tired 2 bearing wise

[@dickynurahman2292]

The more propeller blades, the quieter the sound

[@taqyon]

Thanks! Which one gives more thrust for the same Amps ?

[@dolbyprologicii]

when i record a voice while doing heavy tasks on my macbook... the recording actually sounds like im talking to someone while traveling in a 747 lol

[@nicevideochannel6583]

Hahaha ..

[@straight_intro]

Now we know that turbo fan engine sound during takeoffs cones from fans spinning at ridiculous speeds

[@angelofmusic477]

Sound is not as important as compare to effirciency. Shubeler edf 3 blade is more efficiency than its 12 blade version of the same diameter....refer to their website.

[@calebdrake3544]

Would you know it, the title doesn't say anything about "efficiency"....

[@sticknbones]

In my experience with rc electrics, the esc and motor contribute highly to the sound characteristics. Was the esc and motor the same between both tests? The 12 bladed did sound much better in your vid. Thanks for sharing!

[@nicevideochannel6583]

Both EDF uses same battery and ESC .... But I tried using different ESC and battery on 5 Blade but it never reaches close to the sound of 12 Blades.

[@nicevideochannel6583]

However, I mounted a CPU fan 7 Blades in front of 5 Blade EDF sound was much improved but significant decrease in performance ( thrust )

[@Im_The_Slep]

Time to put that twelve blade turbine in my pc

[@nicevideochannel6583]

Massive cooling solution :D

[@raypilot9958]

perfect for a massive scale 747

[@lazgyrorider3894]

Yes i see.. 12 blade is more quiet & sounds stronger, or did i get it wrong?

[@franciscoe.9989]

RESPECT = GREAT JOB Same voltage for 12 Blades & 5 Blades ? if So, which one has more power / Thrust with the same voltage???

[@ujjwalkhatri4198]

Nice but liked the sound of 5 blade propeller

[@HoweDoYouDo1999]

I almost ducked when I heard that 12 blade that shits ultra realistic now imagine a fucking plane drops into my house after I say this 😂

[@LE-6920]

12 blade fan sounds more quiet. In any case, audible high frequencies much less in it sound...

[@benphillips1149]

large twelve blades hurt ears

[@gisall8205]

Side by side, which one produces more wind velocity.

[@modeljetjuggernaut4864]

With both at Max throttle, 12 blade will go through a battery twice as fast. But ya, 12 sounds better.

[@calebsrccrawlers]

With the 12 blade EDF I was waiting to hear ignition, from a jet, ha ha.

[@nickcarter9538]

You don't use the same motor and cowl to test the fans so your result is skewed, the EDF motor appears more solid and probably has better bearings. I assume both motors are brushless. Still nice to see what the EDF does.

[@joshuaericilac]

Nick Carter your point is a dud because these two are factory setup not modded so how would he have used the same cowl and the same motor ..... think about it before typing it

[@nickcarter9538]

No it's not, the title of video was comparing 5 and 12 bladed fans, not 5 and 12 bladed units, my interest was in the difference in performance of a 5 and 12 bladed fan, to properly assess that difference the same motor and cowl should be used. In addition I now believe the 5 bladed unit had a brushed motor and the 12 bladed may have been brushless which affects the sound considerably. I'm more than a little autistic so I tend to be very literal, I was not criticising the producer of the video but pointing out an error that any engineer or scientist would realise compromised the validity of the comparison, you will also note that I did complement the video for what it did show. I am not a troll but an engineer who wants things done properly so that we avoid misunderstanding of a situation, misunderstandings that occur too much in today's world.

[@realflow100]

Nope they are both brushless.

[@sikrandall83]

Nick Carter you say "the edf" as if they are not both edf units. Supposing there are subtle differences in sound between the two cowlings I think the point of the video is to say generally this is how a 5 blade edf unit sounds, generally this is how a 12 blade edf unit sounds. Of course there are many factors that might bring changes to your exact application but my god we'd be here all of 2018 trying to cater to every individual application. Furthermore the title of the video was not comparison of 5 and 12 blade fans leading one to presume the comparison is the performance of the units. The title of the video is "sound comparison of the 5 and 12 blade."

[@sikrandall83]

AmIonArock so nick says he wants a performance comparison, the video says a sound comparison, you say nick has a valid point. Noted.....

[@Chris-uu2td]

I think these screws poking into the 12-bladed fans duct aren't doing the sound any favour

[@ΧρηστοςΧρονοπουλος-η2σ]

Great video but I love to hear a fuel rc jet engine with aferburner

[@steadycruisin619]

This is cool but it would be better if there wasn't an ear splitting whistle around 6khz

[@233kosta]

That's the PWM, not much we can do about that :/ Maybe get a 50kHz controller?

[@charlesdavis5803]

the 12 blade sounds real!

[@slevinshafel9395]

and what about presure air and air flow on exit?

[@alisdairreid7925]

Is the 5 blade also running a brushed motor can only make out 2 wires? This will also make a difference to the sound.

[@daus7018]

Ahhhh...i like this sound....😻😻😻

[@HoosierDaddy145]

I’m doing a spitfire build 42.5 inch span with two 11 blade 50mms on it @ 4s I hope it sounds like that but double

[@nicevideochannel6583]

it will be bit different i think :))

[@SMQ_90]

is it workable for rc plane or posted to create music in our ears?

[@GooglePlexNull]

Was the mike on the exhaust side? That would have also given you an idea if the 12 blade also sounded more jet like. Thank for you vid demo

[@Kkkppp9922]

I like the 12 blade one more it looks more like a jet engine

[@angelofmusic477]

12 blade nice sound but less efficient when couple to any motor ...due to higher loading....my 2 cents.

[@nicevideochannel6583]

Yes but sounds amazing

[@rottondog1473]

but does the higher loading produce more thrust and if it does, is the efficiency the same when producing the same thrust?

[@angelofmusic477]

@@rottondog1473 as one increase the number of blade, loading increase, efficiency decline means more power require but thrust increase marginally . The famous Schubeler EDF. Google the spec sheet of their lesser blade EDF Vs the multin bladed EDF of the same diameter and you can see a big drop in efficiency for EDF with higher blade count.

[@Ucceah]

it is just me, or is the 12 blade noticably quieter? i have a 60mm 3 blade on a depron wing, and it's almost hilariously noisy and abrasive sounding. the housing you made is a thing of beauty!

[@nicevideochannel6583]

thanks :)

[@djaydeved]

awesome hello from florida

[@fanscarter9628]

5 blades even power but 12 blades nice sounds😅

[@jockellis]

I haven’t watched video but an betting five blade is quieter because it is a prime number. Now to watch it.

[@senpaisanchoyt5225]

jockellis **wrong**

[@jockellis]

SenpaiSancho YT Thank you for your comment.

[@THEADVANCEDGAMERTAG]

jockellis *REALLY WRONG*

[@jockellis]

Clix B8s Did you read my post? I said that was my hypothesis, not my test results, you troll.

[@ilikealotofthings731]

jockellis because "prime number" LMAO

[@gavinmccubbin1087]

the both EDF's sound great but the 12 blade EDF sounds more like a jet

[@agus2001]

Is this a jet? Or just a shrouded propeller? Is air getting compressed?

[@nicevideochannel6583]

No compression I believe !

[@luisantoniomarrega1120]

Mini turbina incrível. Rio RJ Brasil 2018

[@AbuTayibaRCVideos]

Very nice

[@gooberclese]

12 blade sounds better...just my opinion.

[@nicevideochannel6583]

I agree with your opinion :)

[@stew1tx]

thrust test please...

[@BWWGL9]

I want to make a say 21-24" Boat and use 1 or 2 EDF's, any suggestions ??? Only thing I want in the water is the Hull & Rudder... need good THRUST what size EDF and BLADES. ??

[@nicevideochannel6583]

Blade size i dont know. EDF is 64mm

[@andyhughes1776]

What is the thrust comparison?

[@pasadenapauly]

is this what i would use to push a rc hover craft if i was making a diy one?

[@Hamachingo]

A big propeller is more efficient (and lighter), but yeah, EDFs just sound cooler.

[@blumac9801]

The 2nd one sounds better, way better

[@darkodimitrijevic8496]

How did you made this nice Boing style white shell around it? I need two of those (I have the same engine :) And two of them are being prepared to equipped Parrot Disco, in one of his mods called "Disco subsonic" :)

[@emmanuelmanahan3866]

How many RPM, and Pounds of Thrust?

[@233kosta]

How much power can you get out of these wee motors? I should imagine it wouldn't take much to put together something like a 3 stage bypass compressor (EJ200 style!), add a fair old bit of thrust to the setup. If you can get the chooch out of the motor, it shouldn't be too difficult to get your exhaust supersonic, though I would imagine at much lower mass flowrates. Still though - an authentic jet exhaust out of an electric motor would sound cool!

[@TheCentaury]

I hope I never get a neighbour testing turbines ... I hate noise :D

[@chavijr9020]

12 blade nice

[@madmax2069]

I wonder how it would sound with more blades

[@nicevideochannel6583]

I have uploaded new Video 5 Blades EDF with Added CPU Fan 7 Blades and it sounds bit heavy ...

[@nicevideochannel6583]

more heavier and smooth ...

[@blower05]

same voltage and lower speed for more blades.

[@JungleYT]

I assume "EDF" = "Electric Ducted Fan" without Goggling it??? You really need to spell it out for those Folks not in the Hobby... But, yeah, longer wavelength in a 5 - Blade unit = more noise...

[@klabauterius]

How do they compare in engine-thrust?

[@Jimmeh_B]

was that 12 blade under powered? Sounds like it needs a bigger motor or the motor that's on it needs a bigger ESC/PSU. Wasn't getting up to the same RPM by the sound of it.

[@VictorSeedorsky]

Is there any difference in the thrusts??

[@proreckah7339]

Can a 5th blade fan work with 2200kv motor?

[@nateweter4012]

Is there anyone making custom metal housings like the one you have for the 12 blade? I really want to build a working display for my office.

[@faizolismailpejo9076]

where to buy that turbin...if possible all metal.....

[@jhebertdelacruz3607]

The 5 bladed sounds like an airplane engine. While the 12 bladed sounds like a fan. Which is better? A. 5 bladed B. 12 bladed Comment a letter of any reply.

[@nicevideochannel6583]

B
