Personally do not care about the game sponsor. (especially given it's uh... reputation...) BUT there is one thing I'll suggest for the next season and the on thing you had built for it. Which is... put sides around the flap so that when air pushes past it, air can only flow in the same direction as it went into the flap initially from, and no other direction until well after the flap as to ensure you get the most accurate of readings from the flap.

I'll post again so you can see it here. You can get a manometer that reads in millimeters of water column for 80 bucks. It's called a DWYER magnehelic. They have models that go from 0 to 6 mm of water column and another that goes from 0 to 10 mm of water column. I think it would be perfect for this show, and wouldn't cost you that much money. It would also be much more accurate than the 3D printed device you made.

To answer your end of video question, I'd go for the dragon wing. Very few of my fans ever run at 100%, and my PC overall has a gentle hum at idle. More performance is paramount, and under heavy heavy load I'd likely be wearing headphones anyways. I'm intrigued by the hurricane as an exhaust option mounted on the exterior against a wall, or behind a cabinet, maybe with a cage. The outward airflow scatters the heat in all directions instead of in a cone. It could also be used to create turbulence inside of a case to help cool vrms, ram modules, or NVME slots. if used in a pull configuration on a dual fan tower cooler with 2 additional fans out the back and top, it might actually significantly improve vrm performance.

Adding a second test to all fans would be helpful. Put all the fans on a variable controller and measure the noise from about 20in. Then lower the RPM from maximum until you hit 36 dB. Then test the airflow of each fan set to 36 dB. I personally never run fans at maximum, and I doubt most other do as well. I try to put a curve on mine to be mostly silent unless the temps go really high. Some fans I've had (like corsair, noctua, lian li, etc) were vastly different at maximum RPM for performance and noise, but the most expensive ones weren't always the best when I tried noise normalizing them. Right now I'm just running cheap TR 120 ARGB fans because they are dead silent and still keep my PC cool enough. I would love to see an extra test normalized for noise, and I don't think it would take long since you already measure noise and test airflow anyways, you just need to get a speed controller and a jig to hold the mic a set distance from the fans to keep that consistent.
@FanPhys

Agreed - nobody runs fans at max rpm, which is why most of the "on the box" stats are moot. Cooling has improved so much that fans just don't need to run fast in most scenarios. I extensively tested a bunch of 120mm fans and found that they all perform about the same at roughly 1,000rpm, which is the speed that most people will want to run them at. Where substantial airflow and static pressure are required, you just have to forget about the noise factor.

What you've created with the flappie-doodle thing is basically an old-fashioned mass airflow sensor (look one up for a 1990 Toyota Camry to take example). What you're looking for is a manifold absolute pressure setup. Design a manually variable gate and use a manometer installed between that gate and the fan to measure pressure, and an anemometer on the other side of the gate to measure air flow. By adjusting the gate, you can measure static pressure vs. airflow and plot them on a graph. On most well-designed fans, the relationship is not linear; there will be a point where airflow and pressure are ideal. Plug in values for RPM and current draw, and the result is an accurate representation of the fan's overall performance.
@Flumphinator

For the static pressure meter, just put the door on a spring. BMW used this design for air flow meters in all their early fuel injected cars in the 80s. The door was on a clock spring that gave it some resistance and linearized the output. Also, counterbalance the door so that the weight of the door doesn’t exert any closing force; only the spring holds the door shut. BMW did this by simply mounting the door on a vertical pivot. It’ll also be a lot more accurate if the zero point where the door is shut isn’t at 90 degrees. A little preload, like 10 or 15 degrees also linearizes it. Obviously this design isn’t used in cars anymore, because it’ll ultimately never be linear, but you can get it pretty good. Good enough at least.

For your static pressure tester, have you considered an adjustable spring? If you set a target for the airflow to open the flap, say, to 45 degrees, you could adjust the spring tension to restore the flap position to 45 degree per fan, then compare the spring tension values across fan designs. It's an approach similar to used in AFM designs in 80's automotive applications.

Easy fix for your DIY gauge: Instead of designing it as a "swinging hinge" design it to where it has a VERY light weight spring pushing the door towards the cage, then have the door slide along a rail using frictionless bearings. Or even do it without the spring, since that increases tension as it's compressed, and reset it manually after each fan.

We all have more than an fan, so I would try both the quieter one and high performance one, together, on seperate fan curves and seperate headers. It's what I do now with my exhaust fans. One is top exhaust, very quiet. One rear industrial exhaust, powerful but loud. I run controlfan software which allows you to spin fans at speeds depending on the temp of a number of different components, meaning fans nowhere near the heat source, don't have to ramp up. All helps to keep it cool with a good volume balance.

If you were to hook up an a12x25 to it and control the voltage you run to the fan. Then, have linear increases of voltage and track the position of that gate to that. That way, you'd be able to increase the power of the fan linearly and compare it to the height of the door. Just a thought, love the channel.

You could use either a load cell, hall effect sensors and magnets, or a couple external indicators to measure how much the spring compresses to determine how much pressure the fans generate. Adding a worm screw in the back would let you adjust tension minutely, and swapping springs would let you adapt for more granular measurements on fans that are very close in flow/pressure.

I suspect that the response of your new test tunnel would be more usable if the duct extended beyond the hinge point such that the door was contained within the duct with the gauge left as-is. The response will not be linear even with this change and some leakage would occur around the hinge, but the air is more contained and doesn't deflect itself around the door, so more door deflection is required, increasing the resolution at higher pressures. Rather than purchase a manometer, you could make one with some clear hose, a board, and colored water. In your case, I suspect a 3D printed stand to hold the hose might look more professional. I saw some interesting ideas while browsing images in a search engine and there are some youtube videos as well, though I didn't see one here that impressed me. Good luck with whatever test mechanism you do choose.

With a PWM fan, I want the blades that perform the best at my target noise level. Others might want those with the best noise level at their targeted performance. Either way, different performance at different noise levels make comparisons hard. Noise-normalized tests would probably be more useful.

If you do the door opposite with a small spring gravity will help you differentiate more as performance increases.

A lot of the choice depends on how you perceive the fan noise but for me who has tinnitus it doesn't really matter but I'd choose performance over noise every time.

For the questions of shredder vs dragon, i would put the drahon in my case, better cooling and rad fans. I can tolerate a bit of extra noise from my battle station

If it was going in some cupboard somewhere, I'd be prioritising airflow, pressure, basically wouldn't care how loud it is. Given I'm not, I've already prioritised low noise above all else with the Noctua P-14s redux that I have more than a dozen of. 1200rpm of super low noise gentle breeze through massive radiators, with an essentially silent pump, and a large case. You could probably put a sleeping baby atop this thing while it's running benchmarks, and the only thing that'll likely happen is it'll be extra cosy from the rising warm air.

The Hurricane could have applications where you do want to draw air through a space but don't necessarily want positive pressure or don't want the exhaust going in one direction, I suppose.

9:40 Performance first - You can always slow down a fan to make it quieter, and a high performing fan won't need to spin as fast in the first place. But if your PC is overheating and your fan is already at 100%, then it kinda fails at it's one job. That being said I still love the ridiculous designs, definetly don't get rid of them!

I would pick quietness as the most important aspect of a fan. I work in telecommunications. I hear lots of loud fans all day long, and don't want my home PC fan to be noisy.

Shredder all the way, low noise is one of my top requirements for PC fans (and I generally run more 140mm fans at lower speeds on large heat exchangers for that reason).

You can make that original tester more linear if you shroud the sides of the flap throughout it's travel. Put two 'blinkers' on it so air can not escape from the triangular openings created on each side of the flap and only escape from the base. Still will not be linear but it will have a much flatter curve.

The hurricane is basically a tesla turbine being used as a compressor. Generally the planes need to be significantly closer together to force the flow to run laminar.

My thought for a new testing rig was an old school pressure gauge, aka manometer. Either pressurize or pull a vacuum on a U of water on a tube mounted on a piece of plywood. The biggest delta wins! You could also mount a pressure gauge on it for exact numbers but the water visual will be cooler than just a gauge.

For me to choose between Shredder and Dragon Wing I'd want to see a noise normalised comparison. I wouldn't like to run a load fan very fast but if it still outperforms the quiet one even at low speed it would get my vote. On the other hand I could run a quiet fan at %100 so it really depends on what moves more air at the volume of the Shredder at max RPM.

I agree, noise normalised would be a nice metric to see if I was after the best performance to noise ratio for a quiet system, perhaps something that can be added to the next season.

You should use a lever that presses on a kitchen scale to measure static pressure, that way there is basically no moving parts.

Dragonwing still lives in the back of my mind rent free so I have high hopes for the Shredder, the flow did seem decent but then... Razor Wind looks like it'd have turbulence off the back side of the fins but in the smoke test it was one of the most straight forward flows. Smoother had maybe the second best flow to me. The Hurricane looked decent, but I'm not sure how that flow pattern relates to performance as I'm watching. In the end once again Tom's design kicks butt though not as good as the Dragonwing. The new one might have been quieter, but I wear headphones all day.

If your manometer can read negative values, it would be quite interesting to see an appearance in season 6. If I don’t misremember there have been at least one other pull configuration fan design in previous seasons, maybe more. You should pit them against each other, at least as a special non-competition episode.

You should do a side competition for low speed performance. Say 30-50% power runs. For people trying to build near silent rigs who need max performance along with quiet design.

I guess I'm the odd one out. Because I would pick the Shredder. It's pretty quiet, and it moves enough air to get the job done. Also I think it looks better than the Dragon Wing.

You can still slow down the Dragon Wing to perform at about the same level as Shredder, but it still looks much better. :D Actually at some point you might do a noise normalized shootout among the best coolers.
