I work in a hvac r&d lab. We use a piece of equipment called a "code tester" to measure acfm across different static pressures and then calculate scfm. It's a pretty simple piece of equipment to design and build, especially with low cfm applications. Might be worth looking into if you want to start measuring airflow..

Just mounting the fan onto the end of a clear vertical tube with a scale in inches or CM etched or painted on its side, and placing a loosely fitting, weighted ball* into the tube while the fan is blowing air through the tube, and then measuring the ball (or cylinder*) height will give you a pressure metric to measure your fan designs.

One metric that might be interesting to track in the future is how much these fans perform against static pressure. We can infer this indirectly though the CPU results, but it's probably a good KPI to predict performance. Or you could just show the flow rate of the smoke when there's a stock cooler attached.

Should be fairly easy to implement as a DIY solution, just a box with a typical hydro-manometer. Could also have a similar plenum setup for testing the pressure drop of a cooler. The leaderboard should be changed to separate airflow and pressure fans, though, especially as the entire range of fans is only tested on one setup that'll favor one over the other. But it might also be a better idea to just give GN an SLA printer and let them have a go at their own fan showdown, considering they have industry equipment for proper testing and they have proper methodology.

New idea for the smoke test. A 1x1x1 box used to pull the smoke out of. Thus keeping any excess smoke from coming around the fan and making the discharge hard to see. You could also time the amount of smoke injected into said box and time how long it takes to clear out the smoke. Maybe giving a crude cfm calculation in the process.

The air also has to enter the box. Which would cause problems: A. Then it can’t hold the smoke if there is an air inlet in the box B. Even if managed to keep the smoke in the box would act a big funnel. (Cheater) C. The box would never be completely free of smoke

Pretty simple idea. Don't overthink it. The box could even be the dimensions of the fan for height and width but 2 feet long with a divider in the middle. Fill one half and open the divider once the fan is on. That'll show better smoke "suction"

Design: Front swoop is Phi and airfoil shape is brachistocrone curve. This was inspired by 2 fans. The Brachistocrone fan, made to look like air scoops. The Golden Ratio, which had an interesting ring around the edge. If anyone remembers episode number or true callsign, I would appreciate it. Thank you if you're reading this, and have a good night.

Might have mentioned it in a past video, but something to take note of is that humans are very, very good at filtering out constant noise. The issue with a fan that has 2 or more spikes in the spectrum analysis is a phenomenon called "binaural beats", in which the two notes go in and out of phase with each other (kind of like constructive and destructive waves). This mechanism causes a "pulsing" sound to be heard, in a completely different pitch, clashing with the two peaks at the same time. Predictably, this is very hard to tune out.
@woulg
2 жыл бұрын
This only really applies if the tones are close together in pitch (within a semitone i think), otherwise we hear them as two distinct pitches (even though the phases do mess with each other still, obviously). And it's only technically called "binaural" beating if you're listening to them in separate ears (like through headphones - hence bi aural / 2 ears), and the reason it gets a special name is the interference pattern happens in your head instead of in the actual pressure waves in the air. People like to call it binaural beating even when it's not in separate ears sometimes though because there was some pseudo science about this binaural beating inducing certain brain wave patterns which supposedly altered your mood. The reason two notes on a piano (or basically any sound other than clean sine waves) do a bit of this beating sound when they're further than a semi tone apart is because of the overtones of the sound. Overtones are sort of like other sine waves stacked on top of a note (the main note is called the "fundamental"). They usually fall in specific multiples of the fundamental called the overtone series, but they can also be outside of this series (I think this is when we call them partials instead of overtones? But I'm not sure actually), and this makes the sound more sort of rich/dissonant/complex sounding. For example a piano has overtones pretty cleanly in the overtone series, but a bell will have them sorta all over the place and a cymbal will have them even more messed up and the sound of paper being crumpled up will just have them all messed up completely (to the point where we stop even talking about the overtone series in relation to sounds like this). All this gets even more messy when you start learning about the Fourier transform and additive synthesis and you realize you can recreate any sound ever if you can control the amplitudes and phases of 1024 sine waves. Sorry got a bit off topic there. Good point about the fans tho.

So, I just realized that it's probably easier to test static pressure than CFM, and I think the results could be interesting. All you need is a rig to seal up the back (inlet) side of the fan and connect it to a clear tube of some sort. Then, orient the fan so it blows upward, and place the dangly end of the tube in a bucket of water. The higher the static pressure, the higher it will lift and hold a column of water. Even if you don't then proceed to subtract from atmospheric pressure, and instead give us a measurement in inches of water, it'd be useful, as we don't need absolutes to make a comparison. While this doesn't give us a pressure/CFM curve, it at least shows which fans perform better when more obstructed.

Turbines in the field of hydropower generation are normally not designed to suck in water / air or to build up pressure to the rear / front. These should actually always offer the greatest possible re-sanding and at the same time offer a high flow rate in order to keep a high speed as constant as possible.

So yeah. More complicated than it initially sounds.

Please excuse my terminology. I've explained a few major issues with testing and expanded on bonus issue for tests. A total volume test will be great but the final cooling rate will be dependant on a few factors. Heat tranfer speed to the radiator fins. Volume of air drawn across the fins. Volume of air expelled. A closed system airflow test showing the total volume of air moved with the inbound air being ambient and the outbound air being 100% contained as flow through the radiator fans then the air temperature of the output being displayed. The ambient temperature of air entering the system and the ambient air exiting I assume is the temperature being compared. The heat transfer across the fins will depend on the turbulence of the air, i.e. low turbulence equals low transfer. An extended period of turbulence isnt greater, i.e. Difference in heat/time = rate of exchange. A smooth flow will lead to gradients meaning a high flow rate may mean minimal heat transfer. This way, even if the fans spill air in every direction then the captured ouput temperature could be measured assuming there is no air leaking from the case. The total air entering the system and the average input and output temperature could measure the total temperature being removed. "Air" is a poor unit of measurement. The air pressure and moisture of the ambient air and within the case would be helpful. Finally and potentially most important, are there any airflow or smoke test videos of the fan working inside the computer? The airflow tests for smaller fans exhibit cavitation issues which would ruin the fans over time. The sound tests would show spikes. A smoke flow test would show the negative output of the fans. A very expensive set of cameras could be used to measure the IR movement of the air at different points. Before entering the system, before crossing over the conductor, before entire the fan, the heat distribution within the fan and the output. Bonus issues: 1: Aerospace design relies upon very large outputs which desktop fans cannot compare. Few desktop fans designs can accurately measure the extreme stresses involved with upscaling which may be envisioned by some viewers. For example any design with split fins will work differently within vastly different scenarios. So solid fins will only provide data in a short range. 2. Since aircraft lift is dependant on redirection of airflow then upscaled designs would be extremely helpful showing even input and the output flow of the temperature and turbulence of different designs. I'd personally love to see the entire airflow model across wider areas. 3. Since the area of the processer is small why not allow for an airscoop that envelopes the entire body of the inflow plus the fan plus the radiator. I'm sure some of the subscribers would love to have a total area design that they could play with. The fan shape spilling out air wouldn't be a major issue anymore.

Would be neat if you had a static pressure test rig that could double as a flow rig. simple box with a hole in the back that would be opened or closed as a fine adjustment to flow for the hole in the top where you'd put an acrylic tube and a ping pong ball. Adjust the hole size till the ping pong ball is maybe a couple inches from the top as your calibration. The other fans would have to try pushing the ball up the tube to beat noctua. Think lung capacity gauge. This would accurately gauge flow. For static pressure, you could use the same box but block off the air flow calibration hole and acrylic tube. Use a clear nylon tube shaped as a "U" about idk, 8" tall? Partially filled with colored water. atmospheric pressure , the tube sits at rest at 0 inches. Use noctua as a benchmark and see how many inches of water the fan pushes it. This is your static pressure literally measured in inches of water. Doesn't get much better than that. and it's more content, as well as more actual measurable data. CPU cooling is cool and all, but there are too many variables. As an added bonus, these tests can take a fraction of the time it takes you to do a cooling test. ;)

So all you need is to pronounce those letters one by one without pauses. And English has same or close enough sounds - just get an english word that starts from that letter or combination of letters where no letter sounds are omitted. "V" - like in word very, "ya" - yahoo, "ch" - check, "e" - every, "s" - same, "l" - loot, "a" - after. Or you just can use google translate to read it for you - it is not perfect, but good enough o)

@Lassi Kinnunen 81 It could theoretically perform better with more blade surface area on the front, remove most of the center ring, and smooth out the back edge a bit more. I'd be interested in how well it could perform with a redesign as it looks great aesthetically

Since you test 4 fans per video, at the end of season 4 you should take the 4 winners of each season and have a 'Winners leaderboard' and see which seasons winner comes out on top!

It would be awesome it you would take all top 3's of each season to gamersnexus fan test machine. To make a nice collaboration clip but also verifying your own results.

As for the Francis turbine can you squish that down to about instead of that big big funnel maybe squish it down about a few more centimeters and maybe tiny tweak to the angle of attack those blades in that intake are..... Maybe it actually might improve.

And I mean like it would not have as much weight on those tiny motor bearings...... And it would flop around less

according to LTTs recent video its BETTER if a fan does spit out the air in all directions so the airs more spread to feed the GPU with cool air too not just the CPU ,a direct output of air can just smash into the wall of the GPU and not going near its intake, but thats just a front case fan sceneraio for rads etc its different

The only one I could stand the sound of is the Turbine, which I think I would actually use. I do wonder though how this seasons fans would do in a static pressure test rather than open air I think the results could be surprising.

Please add static pressure test bench. ( appling pressure to closed small cabin and getting data by pressure differential sensor maybe?)

Here's a hint for future submitters: the ones that eject a mostly laminar and clean stream behind them score highest
