I keep saying, take the top 5-10 fans and put them into the cheater housing. You'll likely get one that beats the cheater at it's own game

I been watching little fans suck smoke through them for over a year, and I still love it 👍

wow, no mentions of the second to none performing almost the same as the overdrive? I was actually stunned by its performance.

Overdrive was losing a lot of airflow at the seams between the fan and shrouds. I wonder if there's significant gains to be had by designing a full enclosure or using gaskets... I mean, the thing already has bearings and gears. Might as well over engineer the thing

Honestly expected my Cyber Eye fan to do worse lol. Good to see it in action though!

Aesthetically these are some of the best-looking fans I've seen on the show.

I guess the calculations I did were based on theoretical air movement and not actual air movement! Guess it's back to the drawing board! -Nate (Yes, the overdrive creator)

I laughed immediately when he said it was named emotional damage. Steven He is really funny. If you watch a few of his videos you will get the context of what he means by it.

You should try using a super high torque high rpm motor from one of the previous videos to make the overdrive break the sound barrier :D

First thing to do if you want a fan that can beat the cheater is arrange the rear shroud supports to align with the motor supports on the fan housing. The overdrive was a big offender of this. Side note, when doing the smoke test, can you get a shot directly behind the fan? Would be interesting to see how much rotation is in the airstream as it exits.

Dang, i was really rooting for the over drive. I wonder if positioning the guides and supports for the parts in line with the original fan housing would have changed anything. Still, it was an excellent attempt!

I'm gonna work on my hairdo and fashion to look more like a jet engine for that +5 charisma bump.

It looked like you were losing some air out the side of the shroud from the crack between it and the noctua frame. Would likely increase the airflow by simply sealing that tiny gap up with electrical tape.

why did you shift from temp benchmarks to using CFM for the hierarchy. You cant always count on a higher CFM giving better results for cooling a radiator or tower cooler, maybe for a case fan.

What about resin printing the gears instead? not having those rough edges from normal 3d printing might remove a lot of the friction present when spinning the gears.

Congrats on the 200k well done🎉

I noticed on the Overdrive there appeared to be leakage between the pieces, it might benefit from some bolts, nuts and gaskets added to the build.

My interpretation on Emotional Damage : So some basic context first, the clip comes from the comedy skit video "When Asian is a Difficulty" by Steven He. He's just been roasted by a boss in a game called "Auntie" and gets the death screen Emotional Damage. He proceeds to yell it. The fan will cause you to experience "Emotional Damage" from deciding to print it in the first place and will lead a cascade wich causes you to question every sing one of your life decisions, therefore inflicting "EMOTIONAL DAMAGE" (I'm Asian I love this meme too much)

Would graphite be a better lubricant for the bearings in this scenario or no? Genuine question, I know there’s a reason for powered graphite but I can’t remember if it’s use case is for high speed or low speed.

This is easily one of my most anticipated channels to watch every week. Makes me miss the yesteryears of Battle Bots and Robot Wars.

So glad you're back up and running. I love the fan showdown!

I'm surprised nobody has figured out how to make a fan that adjusts its angle of attack based on its speed

i love this series so much, i would love to season 5 use a super cheap tower cooler that uses 1 120mm fan and try to make it better. some kind of non brand name generic pos cooler and make it OK

I love a floating face and hands showing us the new fans of episode 5

wow bro, look at you killing it onscreen, keep it up man, im loving the travel were all taking with you, the transforamtion of your room is amasing, its looking better every showdown

I also want to see how the top performing fans do when stuffed into a Cheater or Overdrive shroud. That would make a heck of an end-of-season finale episode!

i really wonder how some of these gear drive fans would work if they were driven by something like a 3A Delta fan....

Every episode I mostly just look forward to that music with the smoke test. Love your work MJ

I hope you put that bearing into the the center of the sun-gear for testing... That would make a big difference in the efficiency of the gear mesh.

How the heck do you figure the Second to None is 6th, and not 5th? The stats are the same as Falchion, except it spins faster and is quieter.... It's the better fan; If not, tied for 5th.

Congrats on 200k! Love your channel.

Thanks for the explanation that you're wearing camo, I almost didn't notice :P I love watching tech vids with floating heads and hands! It makes it easier to focus on the tech! :D :P

Second to none had some .. emotional damage!

Overdrive could win, it just needs more refinement. Plus, with a motor with as little torque as that, the blade angle needs to be lower so that it can spin faster. It might make less airflow at low rpm, but it would enable it to spin faster theoretically

Hey man, I'm trying to build my own exhaustion system so these videos are very helpful and I really appreciate it! But definitely the best thing I got from the video was the song you play for the tests! Damn man, what a beat! Thanks for introducing it to me.

Amazing as always! Love watching these

The floating head was awesome lol another great episode!!

"Second to none" being actually second be like: "Emotional Damage!"

This whole series made me get a 3D printer and print loads of things but right now I’m experimenting with fan inserts that fill the gap between the fan tip and the casing. Seems to have improved my noctua 140 industrial fans since the gap was so wide. 0.8mm wall all away around fits just fine. Wish I had a real way of testing it though!

13:57 - There is a good amount of air escaping between the fan casing and the shroud, I bet if there were a thin strip of rubber there to seal that up, it would move more air AND be quieter...

In my experience, the closer the thickness of a fan blade approaches zero, compared to its size, like literally soda can thickness, for a computer fan, the better. I'm not sure an aerofoil profile is advantageous, but I noticed that any thickness, at least near the edges, dramatically reduces flow and/or collimation, rather dragging the air more in a circle for a conical output. I notice an obvious difference in effect when I clean that thin ridge of dust off the leading edge of a room fan blade. The airflow does seem to be very sensitive to profile variations.

Long time fan of the show, Grats on the 200K !! @Major Hardware

Considering the lack of a bell housing, the Second to None did amazingly well.

Always enjoy your Fan Showdown. Keep up the good work!

Homie from Michigan! That Micro Center has been a staple in my diet for almost 20 years.

I guess you could say that the Second To None took some Emotional Damage with that ranking.

I'm from Warren and used to shop at the same Microcenter. Cool to know you're from the area.

You did not 🤣 "We're gonna start with Tom today,...." *HERTZ AD with Tom Brady* Perfect timing

I like how, aside from DBa, the overdrive actually beats the A12x25 by 300rpm. Same output for 300 rpm less. I'm sure it could be optimized more to reduce weight to improve it's output.

Congrats on 200K Subs!

Nothing to unexpected. Sound wise, if I had to listen to a fan all day, I find the Second to None rather pleasing. Emotional Damage is probably named after the results of listening to it for extended periods.

Geared fans lose so much power due to friction in the printed parts and abviously more speed means less torque to spin the fan in the first place. I would be intrested to see a overpowered fan showdown where the top 10 gets tested with a drone motor. which has much more power and much greater rpm... put all of them in a housing so you wont get hit by shrapnell though. ^^

I'm actually glad Micro Center is still around. I couldn't believe it when Fry's folded. It was like an immortal giant had been killed by the very thing it lived to facilitate.

Looks like a lot of hot air (getting pushed around.) Lol 'Could not resist.

gotta say those prints look so damn clean. i remember how things where back in the days in S1 xD

Emotional damage hurts. That fan design probably hurts, both to look at, and physicaly painful

When you do the smoke test it would be nice if you had a piece of clear acrylic with a fan cutout that you mounted these fans to. I see a look of smoke being sucked around the exterior of the fans because of the pressure difference.

Would be awesome if you would be able to do a video with the team at Gamers Nexus and test the top performers with theyre fan tester machine and see those results once they feel confident with the machine!

Given how close second to none went to overdrive, and how much simpler it was to print, I have an Idea for next season. How about competition for printing time - winner is the one who gets most cfm / seconds of printing. This way we can have much different designs claim the top - 2 blade , thinner or we can still get the top fans. Slice settings should be the same for everyone- inflill speeds retractions.

I still think I like the temperature tests better, not sure if that's actually a better representation of how well the fan is working, but it made more sense to my Australopithecus brain.

You should look for ceramic bearings and lube for the ultimate friction reduction, I used them on a 250W e-scooter engine, and the difference was somewhat noticeable.

I almost stopped by that exact microcenter when I was on a drive to pick up my 4th Thermaltake armor case.

the overdrive gets the win over the cheater based on looks alone IMO. if I had a choice out of those 2, I'd take the overdrive because it looks way cooler. however if I absolutely needed pure, unadulterated airflow... the cheater of course wins the day.

The tunes during the slowmo 🔥🔥🔥

you got me with that WoW sound... right in the nostalgia center

Somewhere, Steven He's dad is calling this entire channel a Failure as he says he created a Fan Showup when he invented the fan in China 🤣 #EmotionalDamage

Oh Comon! Mine is so similar to second to none but also FAR better optimized for printing - Super light weight, 2 perimeters everywhere. Submitted it over a year ago

*@Major Hardware* 13:16 It would be nice if you could fit the fan in an acrylic sheet or something (front side of fan), so the air "overflow" around the edge is prevented, and so we can see the actual suction of the fan. it doesn't have to be a huge sheet, just like some decimeter(s) around or something, still small enough to film from the side. Or maybe you can even use regular plastic cling-wrap (for food) or something, just stretched out enough to form an air barrier.

This was maybe the most pleasantly sounding set of fans you've yet tested.

the watercooler distro plate is amazing

great video as always 👍🙂

The second to none is a very good looking fan and provided a respectable result while remaining to be a “normal fan”.

Great episode, thanks

I was wondering why it’d been so long since a fan showdown episode- then I saw the Elden Ring reference. We know where our boy was. I respect the grind. 😂

Venturie... Build a fan housing with three or four venturie/funnels norrowing into the sides of it and then expanding out on the inside of it. Set up the fan to promote airflow in the direction of toward the heatsink. Be sure the funnels are wider in the entrance side of the outer housing and wide on the exit end of the inside of the housing. Sorry don't have a computer working now to try and CAD things...

Could you rework the overdrive to where the brace supports are in line with the case supports. This should remove the extra turbulence and improve its results. Doing the same thing to the cheater should also improve its results too.

congrats on 200k

I've been playing around with creating front and rear housings for some PC fans I'm using with a ULPA filter for my 3D printer. The filter needs really high static pressure (so a completely different type of fan should be used) but I just wanted to see what modifications I could make to what I've got laying around that might work for now. I am trying stacking fans as well to see if that helps any. I picked up a Scythe that rotates clockwise to see if contrarotating fans will make any difference. I also am planning on making my own 200mm fan and housing as I'd like a higher rpm model than what the market has available right now. I picked up a 140mm fan with a beefy hub motor that I'm going to pull out for the 200mm fan (I couldn't find a source for a fan motor on it's own). It'll be interesting to see how that turns out.

I wanna see overdrive ran with a drone motor. For the giggles.

Wait, you're a Michigander?! Oh man I would be stoked to run into you Microcenter some day

"emotional damage got last place" EMOTIONAL DAMAGE

I too have no idea on the emotional damage. All looked really cool and I am impressed. Overdrive mode reminds me of some of the 90s vehicles with overdrive that just would never make it up a very subtle hill (less than 3 degrees incline). Very unfortunate the engine does not seem to have much power to push the overdrive mode. That +5 charisma, "Cybereye has completed trial quest, receives +5 charisma and 250 rep with Major Hardware" Lol ...and got me with the sound, thought someone in family left wow on over the speakers. Hahaha. Also, these episodes, are we finally in heroics in say wrath? There was that one that No one would run because that first boss killed all pick up groups regardless of gear score. Old times for me..but the fam plays Floating talking head, ah, good old days :P

Major Hardware you have the best aerodynamic head to improve the fan air flow

I almost missed the stupid camouflage joke. Guess it works!

Emotional damage get's 15th: "EMOTIONAL DAMAGE!" There, you understand the meme now? lol the fan itself IS the meme!

As the seasons progress, the stakes keep getting higher & higher !

Remember the Acceleron? Put that in the Cheater case and see if it beats the Cheater

Fan times to come

The outflow side of Overdrive was backwards. This caused those big support legs to not align with the Noctua support braces. I would expect a small increase in performance on a retest after flipping that part around.

I wonder if the smoke test might work better if the fans were mounted in a "wall" (like the wall of a case). So that smoke doesn't just drift past the fan over the top of it. If you made the wall out of a clear plastic, you could still film it at both angles.

you know, I don't know way when watching your videos the first thing I look at are the two QIDI printers. :) Still loving my small QIDI x-Plus :)

This series is so FANcy

the reason you swap lubricants in the bearings is that they are designed for the loading the bearing is rated for, in continuous use. we're playing around here and just need low friction not load capacity or longevity

Maybe instead of the a12x25 you could try using more powerful fans like noctuas 3000 rpm ones. Just a thought maybe it’d be interesting on fans like the overdrive 🤷

I just happen to be switching out some fans in my PC and testing cooling changes when your video popped up! Perfect timing. I do really like the Size Original SCYTHE 120mm Case Fan Swirl Fins Wonder Snail 2400 rpm 4-pin PWM as listed here online in Japan. Sorry, I can't find the exact listing in the US for you. I think the brand in the US is referred to as Scythe Kaze(Japanese for wind).

An idea for these geared designs maybe add some gritty tooth paste to the teeth of the gears (ironic) and use a drill to bed them in. Then clean them and oil them 👌

I think a battle of the best episode at the end of the season putting the top 3 against each other BUT the fans being re-printed in resin. Fans like the overdrive and the clock fan I think would help them perform even better. Would be super cool to see the difference between an FDM printed fan and a resin printed fan and if it makes a difference

Emotional damage XD lol

They were SOOO close! Now we need Second to None in the Cheater or OverDrive chassis.

A transmission?!?! YES OVERDRIVE I've been waiting for something like this. High hopes for you.
