    Fun fact, fans are being used as speakers. Normally, in a speaker, a magnet induces vibrations onto a cone that pushes air back and forth at a specific frequency. In a rotary subwoofer, however, large, flat blades are attached to a mechanism that changes the pitch angle of the blades from positive to negative, which is actuated by a magnet just like a normal speaker. Changing the blade pitch back and forth at a frequency has the same effect as a speaker cone, but it's able to move a much larger volume of air as it spins, which makes it much louder. This technology is sometimes used in pipe organs to emulate enormous pipe lengths (80, 120, 160 ft long or more) to be able to produce notes that can be felt more than heard. Since they're so loud, though, it creates an excessive amount of noise pollution as the design requires an "infinite baffle", or venting straight outside to produce a desirable effect inside. I saw a guy on youtube make one in his house and nearly shook the walls apart as pressure increased and decreased so rapidly.

  • @SethCrowderMusic
    @SethCrowderMusic 4 месяца назад +27

    For anyone curious about the music theory, you take a frequency (say A=440hz or 440 ocilations per second), the octave is exactly twice the frequency, so say 880hz, if you divide that into 12 segments, that is your 12 notes in western music. The C major scale uses 7 of the given notes (if i'm not mistaken) so you play the 1st note in C major, then the 3rd note in the scale, and the 5th note, and that is your C major chord. (I'm also just a nerd on the internet so take all of what i say with a grain of salt of course)

    • @Midnotion
      @Midnotion 4 месяца назад +10

      @seth6118 Small clarification; you can't just divide the frequencies between 440Hz and 880Hz evenly into 12 notes. Since the octave is an exponential scale, you have to use a logarithmic division where the frequency of each note = the frequency of the previous note * the 12th root of 2. That mathematical ideal is then usually tweaked by hand to make some chords a little more pleasing to the ear. You can google "musical temperament" for more details.

    So the Wonder From Down Under just brought a blower fan to an open-air fan fight. If nothing else, it's served as a perfect example of why those things are so useful and why graphics cards that have them only need one. The downside is the amount of noise they make; if you're aiming for a quiet setup and have enough airflow for it, open air fans are the way to go.

    If you have 4, 5, and 6 blades, the 6:4 is a fifth, and 5:4 is a major third. Also, the C-ness of it depends on how fast the fan is spinning. If C1 from the 4-blade part is like 32Hz, E1 is like 41Hz, and G1 is like 49Hz. I maybe see these in the graph, but it's dominated by the octaves at 64ish Hz and 128ish Hz.

    I just want to point out that, at a certain point, cfm matters. When it comes to cooling inside the tight spaces of a pc case and heatsinks, it's important to strike a balance between static pressure and cfm. This is because not only do you have to push air through tight spaces, you also have to push enough of it fast enough to keep up with the continuously generated heat.
    My personal pick for best overall fan is the Angel! It easily strikes the best balance of cfm, static pressure, and dba, all without cheating by adding extra pieces or protruding out the base. Though I do love both the Dragon Wing and Devil fans as well.

    In music there's a concept called interval, which is the pitch difference between two tones with some arbitrary frequencies. The higher frequency divided by the lower frequency is called the frequency ratio. Due to a combination of physics (harmonic series), and how tuning systems and history of music has developed, certain frequency ratios have been defined exactly or approximately, depending on the system of tuning that's being used.
    Now a major chord always has three tones: The base frequency, a major third frequency above it, and then a perfect fifth as the highest tone. The frequency ratios for these intervals are, 5:4 for the major third, and 3:2 for the perfect fifth interval. These interval ratios are from something called five-limit tuning, but there are other systems such as equal temperament tuning which isn't exactly following pure integer ratios but it gets pretty close. I won't get into reasons why equal temperament tuning is more common today, let's just say it has to do with proliferation of keyboard instruments (pianos, pipe organs, etc.) and leave it at that.
    So, for example, if we take a frequency of 220 Hz as the base tone, the major third of that would be 275 Hz, and the perfect fifth would be 330 Hz. These notes correspond to A3, C#4, and E4 notes, forming the A-major chord.
    Now this fan is designed so that it has three rings, each with different amount of blades. The idea here is that every ring rotates at the same speed, but the different amount of blades gives a different amount of "hits" on air per rotation. The inner ring gives four pressure pulses per rotation, the middle ring gives five pulses per rotation, and the outer ring six pulses per rotation.
    If the fan spins fast enough, these pressure pulses merge together to form audible tones. And the ratios between those tones depend on the amount of blades per each ring.
    Since the blade number ratios are a perfect match for the above intervals, the middle ring produces a tone with a frequency that is is 5:4 of the inner ring, and the outer ring produces a tone with a frequency of 6:4 of the inner ring (or 3:2 if you simplify). So the fan will always produce three tones that form a major chord; the exact tones depend on the speed at which the fan is running.
    If we assume that the fan is designed to spin at 2016 RPM, that means in one second the fan rotates 33.6 times.
    This means the inner ring produces 33.6 x 4 = 134.4 pulses per second, or a frequency of 134.4 Hz. This forms the base frequency of the chord.
    The middle ring produces 168 pulses per second, corresponding to frequency of 168 Hz.
    And the outer ring produces 201.6 pulses per second, or a frequency of 201.6 Hz.
    These tones correspond quite closely to the notes of C3, E3, and G3, which would be a C-major chord. However, if the fan's running speed changes, then it won't be a C-major chord. Unless the speed changes in octaves, or multiples of two.

    Curious what static pressure has to do with cooling a PC?

    • @The_Keeper
      @The_Keeper 4 месяца назад +4

      From Corsair's website;
      "When you think about cooling, you often imagine air flowing over hot components, instantly cooling them. However, PC cases today are packed with obstacles in the air's path-from AIO radiators to the dense fins of your CPU cooler. This is where static pressure steps in, powering through these impeding components to maintain airflow and keep your system cool.
      High static pressure fans are essential for components that rely on a steady flow of air through dense fins for cooling, such as water cooling radiators and heat sinks."
      Basically, it allows the air to move through tight spaces.
      It is extremely important in small/tight cases where you barely have enough room to build in.

      @The_Keeper in tight spaces forcing air through is important. I've never seen the inside of desk top computer that was so packed pressure was needed. I could see it in a laptop or if you had it hooked up directly to a radiator. Even then radiator is pretty free flowing for the the size of the fan being used.

      Look up some ITX cases.
      Some them can barely fit the components.
      Thats where a decent static pressure is more or less a must to get air to not only the CPU and GPU, but also the VRM and RAM, especially considering most of those builds are watercooled and won't be passively blowing air over them.
      To be fair though, the static pressure in most builds are a very secondary concern. You just need *some* pressure, not a small hurricane as some people tend to think.
      Espacially if you're not running a positive pressure build.

    • @taitano12
      @taitano12 4 месяца назад +2

      Static pressure is what carries away heat.
      If the pressure in direct contact with the radiator fins (the static pressure,or SP) is higher than the surrounding air, it will distribute the heat better, thus carrying away more heat. The Wonder from Down Under is increasing the incoming pressure, which draws heat away as it expands into the lower pressure of the surrounding air. Refrigerators operate on a similar principle by compressing and condensing a coolant that carries heat away, boiling or otherwise expanding, and radiating the heat away through the fins. In cars, liquid cooled computers, and a lot of other devices, the coolant doesn't need to boil or expand, but the radiator slows the air being drawn through it by the fan, and thus is reducing the air pressure on the fan side.
      In a car, the increased static pressure on the side opposite the fan comes from the forward movement of the car. The increased pressure gives the radiator more molecules to pass the heat energy to, which then dissipates said energy on the other side as it passes through the fan.
      Since desktop computers don't generally move at a speed that provides enough SP to sufficiently cool the PC, TWfDU provides that pressure. If a fan is drawing air through the fan, the SP of the surrounding air is then higher than the SP inside the fins of the heatsink. This is, of course, reversed when the air is pushed through the radiator/heatsink. Pushed air gets its SP from the fan and housing. Pulled air gets the SP from the surrounding air. The latter usually gives more control over the SP differential, but both work on the same principle.
      Focusing on the SP, whether increasing or decreasing it, is what has the greatest effect on a Fan's efficiency.

  • @TorkildKahrs
    @TorkildKahrs 4 месяца назад +1

    I really like the concept of the C Major fan, and hope the following can help evolve the design.
    A note is an audible constant frequency. An interval is relationship between two notes. A chord is two or more intervals played at the same time.
    As shown in the video, an octave interval is either 1:2 or 2:1 of the frequency of the note it refers to. That reference is called the root, and is the note that names the chord. E.g. A C-chord has the note C as its root. A so called major chord combines the the root with a major 3rd and a perfect 5th interval. The relationship between the notes in the chord is always the same, no matter the pitch of the root.
    The notes you find on a piano (twelve-tone equal temperament) are equally spaced in twelve notes between each octave with the ratio 12√2 or ≈ 1.05946. For fan design it might be easier to use these ratios:
    Unison = 1:1
    Major 2nd = 9:8
    Major 3rd = 5:4
    Perfect 4th = 4:3
    Perfect 5th = 3:2
    Major 6th = 5:3
    Major 7th = 15:8
    Octave = 2:1
    Good luck!

    Labyrinth seals on the side plates.
    The problem with pressure is blow by.
    Blow by is limited by clearance.
    Labyrinth seals run far larger clearances by dividing the pressure drop per seal.
    Ok,
    Short version, the rotor has a spiral raised on it.
    The side plates have an opposite spiral on them.
    This gives many many intersecting seal edges (its edges not area, think hose vs restrict or plate) plus the imparted angular velocity of the air is forced outwards in exactly the same way on the stator as the rotor.
    This then acts as both centrifuge and scroll compressor with smaller blow by.

    As a professional audio engineer I can concur that a fan (or any thing in motion) can be both extremely quiet and yet still annoying if all the sound is built up in a narrow frequency band(s). think whistling vs blowing air with an open mouth.
    An octave is a doubling of frequency. its named oct because in music that double is 8 notes up or down.
    Fun fact: good car tyre designers use the opposite approach to Milo by making sure the tyre grooves are not properly regular as otherwise your car would make a distinct 'note' at a held speed and it is one of the ways they reduce traffic sound pollution.

    An Octave is a doubling of frequency of the note. So if you start on a C3 and you go up to a C4, the audible frequency of C4 is double that of C3. An Octave consists of 12 notes C, C#/Db(flat), D, D#/Eb, E, F, F#/Gb, G, G#/Ab, A, A#/Bb, B, then the Octave is the next note C
