🔥 3D Printed PC Fan Test: Does the Anti-Stall Ring Boost Performance? 🌀| Fan Showdown S6E3 Follow-up

Welcome to Major Hardware! Join us for an in-depth exploration of PC cooling technology as we conduct a precision static pressure test on a 3D printed PC fan featuring an innovative Anti-Stall Ring. In this follow-up to our fan showdown series, we use a Fluke 922 airflow meter and a custom static pressure test bed to measure the fan's performance under controlled conditions.
Understanding the Anti-Stall Ring:
The Anti-Stall Ring, mounted on the fan's intake, aims to boost static pressure by facilitating back pressure airflow.
Experiment Details:
Witness firsthand how the Anti-Stall Ring affects cooling efficiency as we compare the fan's static pressure with and without this unique feature.

That's 3.3% increase that's pretty good for a static piece of plastic

[@ZappyOh]

Actually 3.0 is 3.45% improvement over 2.9.

[@EitriBrokkr]

@@ZappyOh touche. That's even better 😁

[@adr1uno638]

Maybe it's just becaust it shrink the intake

[@bigbearnelson]

Don't forget that it's maybe $0.05 worth of PLA and would take probably 7 seconds to print on one of those fancy BambuLabs machines. It's easily the cheapest 3.45% increase on something naturally aspirated, including slapping stickers on a Honda...

[@m_cabral]

If this scaled up to a jet engine you can bet they’d do it even if it cost more than a nickel!

[@Wuptidoo]

As a famous philosopher once said "if you like it, you should put a ring on it.... To improve the airflow"

[@Vatharian]

It certainly improved the airflow, when I put the ring on my wife... :(

[@AquaticRobotic42]

I’d suggest printing another piece that’s exactly the same but without the triangular holes… question is whether the piece was acting as more of an optimization on the ducting or if the recirculation is where the boost comes from

[@Tletna]

I agree. And, after that try different shaped, sized, or number of holes to see if it really matters or not.

[@JeoshuaCollins]

Is this going to be yet another Fan Showdown Meta, going forward?

[@mikelarin8037]

Now I wonder if it's the little cutouts or just the choked down inlet that's doing it

[@DUKE_of_RAMBLE]

Same! I'm suspecting it might be some "velocity stack"-like effects, accelerating air going in. Also potentially that it could be blocking the common (I dare say, only) passage for backpressure air to escape on fans: around the edge.

[@jasonk1540]

It's the fact that it allows backflowing air a path around the fan which prevents turbulence. That's what was explained in its introduction video

[@Anthraax]

Could print out two rings with and without the holes and test them

[@nirodha7028]

⁠@@jasonk1540yes but until scientifically proven by showing the difference between a ring with holes and a ring without holes that is just a statement… and even when a ring with holes outperforms a ring without holes there is still no proof as to ‘why’ the holes help unless another test specifically designed to show their effect is performed. Eliminating variables is the name of the game.

[@Side85Winder]

​@jasonk1540 there is no proof that it is even effecting the backflow. The smoke test wasn't shown clear enough to be conclusive on this. I bet it's acting more as a venturi effect. The air flowing past is causing high pressure further down the ring. This causes the cut out holes to suck more air in total. Creating a bigger cone in cone open ring with a 5mm air gap should increase it more than the 0.1 achieved.

You could also smoke test it while on that static test bench. Then you’ll see the ring functioning.

[@nicholashaworth4110]

Nice proof of concept.

[@jacobrollins37]

Finally, he did the test. Happy you are feeling better.

[@MicaAvali]

I think the increase in pressure is coming from the curve radius, allowing for more laminar flow over the edge into the blade. Vs the sharper edge without.

[@DJgregBrown]

perfect proof of concept

[@AlphaMachina]

That's promising. I wonder if there's a way to scale it up, or at some point, diminishing returns?

[@nanaki-seto]

at the rpms of the fan not really at high rpms 10k and above you could do all types of tuning to just the ring to really boost the performance and this modest boost someone said 3.3% as is right now at high rpms like 10k and above it would likely see even higher boosts likely close to 10% that is if it would hold together at those rpms which is unlikely but duplicated in steel it would hit that mark. Just an educated guess but i see it working similar to a spoiler or f1 cars wing they wont do much of any thing at 10 20 mph but once you hit 50 60 and above they have massive effects. RPM is just mph going in a circle basically LOL But as speed goes up the effect will increase until a point where diminishing returns is reached. Technically it wont ever stop seeing some improvement just that the return on investment will decrease to a point where it is not worth while He could ramp up the rpm using a drone motor from 2kish rpms to what ever the blades will take and run the same ramp up rate twice once with and once with out and plot out the boost in a graph and include information on how much the gain diminishes over time after it hits that point. The thing is that point could be way higher than what the printed fan would take before blowing apart

[@AlphaMachina]

@@nanaki-seto Thanks for the reply! Yeah, seems like you're extremely limited in what you can do at these low RPMs. Taking ideas from condensers and the like isn't really all that feasible.

[@lukeb4687]

thanks!

[@Tletna]

I'm sorry to hear about the pinkeye and the bad eye drops. It's part of why I don't use eye drops despite sometimes having tired or dry eyes. I don't like putting anything on/in my eyes. It is part of why I don't wear contacts either. Anyway, glad to see your eyes look good now. Thanks for making this follow up video. I was curious on how much that ring affected things.

[@mattf9096]

If you took that same concept and instead of holes you had curvy channels that led the air back to the center you could tune in the air pressure to create suction.

[@JagoTFC]

The time it took to go down and the time it took to go up .1 tells you that the effect takes place after the fan builds up pressure under the blades, so results may vary from a case to a heatsink application. Anyway thanks for taking care of this detail!

[@chrisperrywv]

I wondered this exact thing during your video. Haha.

[@mealex303]

try some with and without a varnish coating for smooth airflow

[@John-gm8ty]

these new water fans are something else!

[@BooleanDisorder]

[@bitkarek]

thanks man! now i can sleep well.

[@cocon16_PW]

That is exactly what we were missing in the last episode. Thank you for listening to the feedback from your community (fans? 😅).

[@TBonerism]

I do wonder a bit if there is a seal on the ring if you can squeeze out a little bit more performance from the ring.

[@Petrolhead99999]

I somehow doubt that the vent holes are recirculating and preventing stall. I feel like they're either 1) functioning like a wing tip on an aircraft, smoothing the vorticies over the end of the wing/fan blade or 2) providing a boundary layer cushion for the intake air, improving flow. The airflow around the edge of the tip, against the shroud, is stagnant. By smoothing the transition at the extreme blade tip, the airflow is less turbulent? Maybe...

[@kevinspyrle5538]

Thank you. Now I can sleep at night. Of course does it help all fans, or just that one particular fan?

Oh yes, I had forgotten about good old pink eye. Yep I had that coming back over and over, along with a massive candida yeast outbreak, shingles at an early age, scleroderma and morphea, arthritis of the knuckles, and bunch of other nasty things.

[@NagoyaRR]

You should have tested the shroud on the normal NF-A12

[@wowgggearing]

this is what i want

[@NuffMan_]

If you ever have pinkeye, just try to keep you eye shut and dont open it. i've had it few times, and just keeping eye closed works great..

[@208Concepts]

But is it the airflow through the ring or is it an increase in velocity by restriction?

[@hipinretku]

Pretty creepy zombie eyes at 0:30. But good thing you got cured, so we can see more content :D

[@WolfArena]

I think the holes on the ring suck in the boundary layer of the incoming flow.

[@EliteRock]

I recently confirmed that the finish on fan blades definitely affects performance - I replaced those on my Asus Dual GTX1070 a couple of years ago with 'Everflow' ones but recently got hold another set, this time by 'Power Logic' (on the off-chance they wouldn't have the annoying buzz the first set has above c. 67% / 2500RPM - at £6 why not?). Both are OEM to Asus I believe, BUT the blades on the Power Logics are rougher-looking mouldings (otherwise exactly the same shape/geometry) and at the same RPM GPU temps are noticeably higher, for e.g. with the card pulling 140W and the fans at 2500RPM, 20°C ambient about 64°C vs 61°C). BTW, they don't buzz like the Evercools but of course have to spin faster for the same temps.

My condolences RE: eye-drops. My eye doc rec'd I use some, so I tried ones with preservatives first. Worked well, but then a scratchiness builds over the week, apparently from the preservatives, online says. Bought a few preservative-free ones and, fast forward a year, I now know I am violently allergic to preservative-free eye-drops. My eyes swell shut and it takes weeks to go back to normal once they deflate and are crusty and dead. No red eye though.

[@noxious89123]

It might seem like a tiny amount, being only 0.1mm of h2o... but that's +3% static pressure. The increased pressure should also result in increased flow in actual use.

Wot if the ring has no holes and you try it again....is it just making a tighter anular gap...drop everything including your wedding anniversary and test it NOW! 😂

[@prjndigo]

I don't think it actually does what the creator thinks it does, I think its removing the blade tip turbulence without having any actual flow through the slots and could be replaced with a simple lip.

[@ABaumstumpf]

You do need a more precise way of measuring static pressure cause ... well from 2.9 to 3.0 and changing that slowly might just be 2.94 to 2.96 really (or even less). And while this setup does measure static pressure that is NOT the type of scenario those fans are designed for nor really a useful result: You do want airflow, you do want restrictions, but you ONLY want to restrict the airflow, not fully block it. In this scenario the fans behave rather differently cause effects like stalling can occur. And fans don't just have a linear relation between speed and pressure. A Fan might very well deliver the highest unrestricted airflow as well as the highest blocked static pressure - but when just moving some air with some restriction it performs worse than others (thankfully with the always identical motor/driver assembly a lot of the variations are controlled for).

For the getting sick again... I know this is gonna be rough, but chew garlic. It is actually helpful, garlic that is, but... you gotta masticate it, or crush it in a mortar/pestle and ingest the result of that instead. It has to do with the way the garlic gets broken down. I eat some with some meat and/or cheese to help tame it a bit. To put into perspective the amount it may or may not help... I only got sick once in the past year and few months so far. I use city transit. So I am not without potential chances to catch something. But pink eye... heh... sorry friend, garlic won't help that. As for the 0.1 increase in airflow. I'll take it. It may not be much, but every last drop of potential cooling performance is worth it, especially when trying to reduce fan noise. If 0.1 can help shave off 100rpm on the fans, that's great. But... won't know if it does or not til someone tests it, wink wink, nudge nudge.

Man, that looked like a bad case of conjunctivitis...! I haven't had conjunctivitis that bad since I went to Amsterdam in 2012. That was some fine conjunctivitis I had back then...
