Posted June 16, 2023 (edited) Here are some statistical comparisons of some of the more powerful 120mm fans. Data are based on manufacturer's published statistics. Note that manufacturers don't all use the same testing, don't usually report their fan curves to the public, and some of them lie. All fans are PWM. The links to each are in the first list. Note: The Delta listed is 80mm3! I put it in for fun. Note: Some are deeper than 25mm. Note: mmAq is the same thing as mm H₂O. Where necessary, I converted from imperial (e.g. inches) to metric. I used Convert Units. Hopefully, I didn't make (m)any errors. Some companies use minutes instead of hours, so I relied on my calculator for the very complex equation. So much for the usual suspects being the champs, aside from the A12x25 being the quietest. In order of static pressure (mm H20) (with RPM).

Every fan company "lies" about their dB values, because they never give values that are generated in actual use case. The fans are usually tested in anechoic chambers designed to damp any resonance or reflections which drastically reduces the sound levels that it produces. They also almost never quote how close or far away the sound level was taken so it's pretty much whatever value they want to stick on the fan spec sheet. "Our fan is only producing 17.8 dB when sitting on a piece of damping foam in an anechoic chamber taken from 5 feet away." Like how is that even relevant? This is why I quote how far away and in what position my readings were taken from so that it has proper context. Link to comment Share on other sites More sharing options...

Posted June 17, 2023 55 minutes ago, RevGAM said: I know that fan depth affects SP. Does it also affect AF? @TeraSeraph @Lurking @NorKris To further answer this question, up to a certain point it increases airflow at the cost of higher amperage and wattage, then losses start to set in as the air gains more and more angular velocity with deeper blades. Contra rotating fans with stators start to be more effective once you reach a certain depth of fan. There's only so much work you can impart on the air with an axial fan before it is going completely sideways. This is the same reason turbine engines are staged in sets of blades and stators to impart more work on the air for a given depth. Higher advance ratio fans will tend to spill more air to the outsides if they do not have a stator built in. The Noctua S12A is a good example of this with it's relatively aggressive blade angle.

Yes, I have a few fans that will move across my desk if I let them, but I'm pretty sure I don't want them moving my computer. =) Advance Ratio: The ratio between the distance an aircraft moves from one revolution of a propeller(s), under specified conditions, and the propeller's diameter. It is the ratio of the forward speed divided by the product of rotational speed and the diameter. All propeller performances are compared at the same advance ratio.

Posted June 17, 2023 4 hours ago, RevGAM said: Thanks for the response! Can you clarify the "point in increases"? It would depend on the blade design but once you reach a certain depth you're just spinning air inside the duct vs actually pushing it in a linear fashion. So say if you had a narrow but long space to put a fan like the top of a traffic tunnel, but you want to move a lot of air in the axis of the fans. You would want a lot of fan depth with a small diameter which is where stators and contra rotating fans that correct the flow are crucial for efficiency. 4 hours ago, RevGAM said: Not a term I'd seen regarding fans before, and I'm not really sure how to apply it, since it how far an aircraft moves in one, full revolution of the prop.

It is the ratio of the forward speed divided by the product of rotational speed and the diameter. All propeller performances are compared at the same advance ratio. At what depth does the stator become useful? If you flip your point of reference so that the fan is static, the advance ratio can also be viewed as how much air is moved for one revolution of the blades. Higher advance ratios will move more air for every revolution of the blade. Higher advance ratios are generally better for performance as long as you can drive the blades on the fan. Since energy is conserved, the extra movement of air has to come from what is supplied by the motor. Stators or correction grids are always useful at any depth since they remove the angular velocity of the airstream. The NF-F12 has a fairly good example of real stators on a fan. A fan with stators straightens the airflow as it leaves the fan, making for better pressure through fins, and also a more focused airstream.

They're going to move more air for every revolution because of the greater tip velocity, duct area, and blade size. Increases in airflow are exponential with fan diameter until you begin to cause flow separation at the tips or even reach supersonic tip velocities. For example the recent turbofan sizes have gotten larger and larger because of the efficiencies gained. Noctua has a really nice list of their fans with specs. Take a look at how much more air the 200mm moves for only turning 800 RPM vs the 140mm at 1500 RPM, and then the same pattern repeats with the 140mm vs 120mm, and so on. Each step up in size is a massive gain in airflow per revolution. https://noctua.at/en/products/fan Link to comment Share on other sites More sharing options...

A lot of these tests also ignore the rated lifespan of the fan which is 150K hours or 17 years of estimated run time 24 hours around the clock. As well as the power efficiency of the fan motors which is more impressive when you start to look at portable applications outside of desktop PCs. If I could only have one model of fan to use for a build it would be the A12x25 Link to comment Share on other sites More sharing options... Link to post Share on other sites More sharing options...

Posted June 17, 2023 6 minutes ago, NorKris said: only T30 ofc, but thats a 3cm one so I don't really count the T30 or the Lian Li (120mmx28) fans in my testing because they're not true to the 120mm x 25mm form factor. It's not a fair comparison and there's a LOT of compatibility issues with both of those fan models because they're thicker. I do however count 120mm x 15mm form factor because it's well established and there's a fair number of models out there. Maybe if others start making 120mm x 30mm fans I will reconsider, but right now I'm more likely to examine some 120mm x 38mm fans as they're also more common than the 30mm FF.

It's not a fair comparison and there's a LOT of compatibility issues with both of those fan models because they're thicker.

Posted June 17, 2023 One day I will mount up my 120x38s again, but not today Right now I am not using a single high performance fan and it is a nice change.. so quiet I like T30s because they perform close to my 120x38s, but are much quieter, even at 3K. Most consumer fans are a bit of a joke, and are quite weak.
