season 6 episode 4 of the fan showdown welcome back to well I guess this is your first episode ever of the fan showdown welcome to the fan showdown this is a series I run on my channel where basically you guys out there the audience tries your hand at designing what you think the best PC cooling fan is specifically for static pressure in this specific season season six you guys then send the designs to me I print them out and we put them all against each other to figure out who out there is really the best when it comes to designing PC cooling fans that sounds interesting to you go ahead and get subscribed and start designing your fan for the season the next season but anyways the first fan up to dat is the power cap which was designed by Archer now we're only in episode four of this season of the fan showdown but a trend is starting to appear and that trend is centrifugal fans archers said this is a radio fan combined with an actual fan with the inspiration of electric motor fans so think about like uh electric motor like you'd see in industrial settings most of the time you see those big giant Motors and on the end there's like a cover if you look in the little hole at the end of there you can see a little fan and essentially what the idea there is as the motor spins and does work that little fan moves there down the outside of the fan case or the motor case to help keep it cool and that is the inspiration for this specific fan the idea of the power cap design is to draw air into the center of the fan using these Center centrifugal blades or these interal style blades to hopefully produce a higher static pressure than you know a standard axial fan now I don't know how I don't know how well this specific design is going to do at the very least I imagine it'll be pretty quiet given I normally measure from the front and it's kind of all closed off and given how closed off it is you would think this is pretty tough to print but it actually wasn't it printed very easily the supports all came off pretty nicely so all in all it might not do the best but it's a pretty it's a pretty good design now this next one's pretty interesting this is the C major and it was created by Milo and I know what you're thinking right out of the gate you're looking at this design and you're like how how is this going to do any good and specifically this season of The Fan show when we're doing static pressure there's like no blades and you're probably right this will more than likely struggle I I think it'll be lucky lucky if it gets over 1.0 or just 1 millimet of H2O in the testing but the goal of this fan was not to produce or make something that performed exceptionally it was music now trust me when I say I I don't know anything about music I really don't even listen to much music and mostly just podcast but anyway I don't know anything about music so after I go ahead and tell you everything I'm about to tell you make sure to go down in the comment section below and figure out what I got wrong because I feel like I might be about to lie to you here we go Milo said they wanted to create a fan with a balanced sound profile and after watching a few videos of the fan showdown and doing some math some music maths and then some testing on their own Milo landed on this Design This is actually the 11th version of this said design the c major and you probably already noticed that the blades are in a very specific area on the fan disc there's very specific amount of them they have a very different angle of attack based on where they are and the idea here is that is how we're going to create that balanced sound profile and if Milo's music math is correct in predicting what kind of sound this produce it should produce a C major a C major chord now if I understand this correctly which I I probably don't this this fan has three concentric rings on the fan each of those Rings should produce a different Octave of the c major chord C1 C3 and C5 Milo said now I couldn't tell you what an octave really is because I generally have no idea so I would say go ask chat GDP because if I told you anything that's basically I would just be regurgitating what the robot told me but what I do know based on what the robot did tell me is that the C1 should have a frequency of 32.7 Herz the C3 should be 130.81 and C5 should be 52325 now I don't I don't know what ring should make each one of those sounds but if I was to guess I would assume that the ring on the Outer Edge should produce the higher frequency it is moving faster but again check the comment section to figure out if that's true or not luckily for us the sound measuring software that I use Rew or Ru or whatever it's called shows the frequencies so if Milo's maths is correct we should see some spikes right around those specific frequencies Milo did say the calculations they used for their fan design was based on a fan that you know spun at 2,000 RPM when I measured this one I got 2016 RPM so should be close this fan is easily the one I'm most looking forward to in the sound testing performance testing is going to be a little rough but should be a good listen next up we have Daniel and his fan sawblade not much if anything was said about this fan Daniel just said that if you look at it from the top down it looks like a saw blade and that's that's what it is it's called the saw blade there it is although not much was given about this faned does look pretty good should should do better than Milo's fan probably won't sound as good but guess we'll just have to see now last but definitely not least is this thing this is the Wonder from Down Under and it was created by Stefan now Stefan's going straight for the wind do not pass go do not collect $200 just straight up winter winter chicken dinner that's a thing still Stefan said while designing this fan he gave zero considerations to airflow and only cared about making something that would decimate every other single fan we've ever tested in season 6 in static pressure and hopefully every other fan to come shot fired shots fired essentially what Stefan has done here is turn the a12 x25 into a [Music] Turbocharger kind of sort of more like more like a blower fan but I think this thing's going to rip also I just love the Simplicity of this fan there's something about fans that look somewhat complicated but are very very simple to print this is essentially just three well four pieces if you count the fan and some Hardware the both sides printed super easy they're just no support flat on the bed even the fan itself looks a little little goofy but prints super easy all in all it's pretty unique especially compared to other blower fans we've kind of seen over the seasons and again I think this thing's going to going to tear it up cuz blower fans pretty good at static pressure we all know that also just look at how small that outlet is you can definitely tell stepan gave zero shits about airflow this thing is static pressure all day every day but before we find out how well this thing does and hopefully it does do well or I'm going to look like a bit of a fool we got to listen to these fans specifically the c major so keep your ears open the Wonder from Down Under came in at 57.9 DBA the power cap came in around 48.1 the saw blade came in at 46 and the c major came in around 51.5 but more importantly when we're looking at the peak frequencies of the c major what we see is one Peak at 33.5 another one at 134.5 which are pretty darn close to C1 and C3 the C5 frequency is a little less noticeable there's nothing really down there by 500 but there is some noise leading up to it it but either way this is pretty darn good work and it doesn't sound halfway halfway bad now the big question will it push any air at all or is it just is it just essentially a musical instrument a [Music] [Music] for performance- wise the c major came in at 1.4 mm of H2O the saw blade came in at 2.6 the power cap 2.8 and the Wonder from Down Under a whopping 8.0 what what the f placing the c major in fourth place the saw blade in third the power cap in second and the Wonder from Down Under in first and overall they finished first eth 10th and 17th now the Wonder from Down Under not only won today it put itself so far in first place that it is just miles ahead of anybody else at this point it's going to take some significant work and some design prowess to come up with a design that's going to produce more than 8 mm of h2l on our specific setup but I think you guys can do it so if you're interested in trying to beat the Wonder from Down Under just creating another musical fan make sure to go down in the description below I have a bunch of links to different resources you can use models to use as templates I have drawings to make sure that your fan fits on the a12 x25 frame unless you're doing something crazy then it's just kind of up to you on how it kind of works itself out after you have your design make sure to send me a STL or a STP to the fan showdown gmail.com I'll then print them out test them all against each other and we'll find out if you can make something really cool sounding or something that just absolutely rips till next time
