IS THIS MAGIC? This Fan Has No Blades | Fan Showdown S2E3

ho ho ho ho back again so soon yes it's fan showdown episode three and we're gonna well actually before we get going on that i did a thing yesterday i made i made a twitch channel i'm not really sure what i'm going to do with it but uh i thought it'd be like a cool platform for us to like hang out and chill where you guys can ask me questions or just come talk or just watch me suck at video games i don't even know maybe we'll design fans on it who knows what we'll do with it but if twitch is something that you do here's my link head on over there maybe follow me or whatever you do on twitch and um we'll hang out if i figure out how to use it i should but you never know back to business this verse fan might be something you guys recognize as i used it in a previous video where i was exploring you know 3d print smoothing so if you're ever wondering why i don't smooth out the prints that i you know all the fans here on the fan showdown boom answer's right there or there it's one of these sides either way there it is this is the trinity it's a three blade a thick boy fan created by eric and congrats eric i'm making it to another video you're straight up killing it eric said that the main thing that he was focused on when creating this fan was trying to reduce turbulence but other than just reducing turbulence he also wants to increase the air speed of the trailing edge of the blade and he went about doing this by incorporating an actual airfoil design eric also went on to say that he is a manufacturing engineer with seven years experience and before that he was a design engineer so those two disciplines combined provide him with exactly zero years experience when it comes to fan design his words not mine i'm just saying what he what he told me well eric what you lacking experience you make up with the plan and regardless of how good it is it's still a plan which is which is more than some of the fans that have been submitted next up we have the airfoil designed by matt he didn't really provide much of an inspiration behind the fan design he did say that it is it has some sweet aerodynamics and although it's not the sexiest if it prints well it should crush the competition now i don't know if that's foreshadowing but matt's confidence level in his design is off the charts also i do find his design intriguing at first it just looks like a simple two fan blade design but on closer inspection i noticed that the top side has like this hard edge kind of like a stealth fighter whereas the bottom side's a nice smooth straight edge matt was there some sort of maths involved in this design or you just yolo it and just claim victory because i respect you the one now breaking away from the common fan we we come to ennis and his fission fan apart from submitting the fan and saying my name is pronounced ennis there's literally no information on the origin stories of this fan designs to make matters worse i probably put that name up too so with no origin story let's let's build one it's my belief that ennis is a huge fan of the channel and at some point in the past he watched my 3d printed tower cooling video and was intrigued by the infield that i used and he thought that that infill would be better served as a fan so that's what he did he created a fan that's comprised of two sections of slats that are 180 degrees opposed and boom you got a fan not gonna lie though these crazy designs even though they hardly ever work they're some of the most fun to test i'm pr i'm i assume that you guys think that the funnest to watch too and i know funnest is a word because i just said it and staying outside the box and then proceeding to light that box on fire we have sean and his fan bladeless now sean did provide a bit of context to his fan firstly he said he just finished up watching all of the fan showdown videos which uh thank you sean much appreciated and while doing so he found it interesting that all of the outside the box you know ideas and designs always seem to lose a lot of air by just throwing it out to the sides now taking from this observation he set out to take advantage of what he noticed and create a fan that has no blades at all so what he's got here is a series of concentric circles that build outwards from the center and increase in height and what he's hoping happens is as the air is thrown outwards by the centrifugal forces it's going to be guided down by these circles into the heat sink now he doesn't claim that this is going to be the best fan ever created but he does expect it to do pretty well in the noise test and he considers that this design will be a win at least to him as long as it keeps the pc from thermal throttling and i i agree if this if this doesn't throttle that's a win so given that let's start with the bladeless and the noise level testing the bladeless performed as promised coming in at 42.5 dba the fission came in at 46.8 at a much harsher tone the three scoop came in at 48.5 and the airfoil came in at 46.8 and being that it's a two blade design it had that nice low hum which i personally prefer over a high blade count high screen but as sean predicted the bladeless performed very well in the noise test besting all the other designs but was it really moving any air at all there's only one way we can find out [Music] so [Music] [Applause] [Music] first off props to sean you noticed a pattern you watched a lot of previous videos you saw some sort of phenomenon you wanted to take advantage of that and well you nailed it not only is it incredibly quiet but as you predicted the air moves just as you wanted it to and we can see it proven in the smoke test it does exactly what you described but sean can you pull off the hat trick can you keep the old 7700k from throttling let's find out the airfoil finished with an average temperature of 77.2 at a room temperature of 19.7 giving it a delta of 57.5 the fission finished with an average temperature of 87.3 at a room temperature of 19.9 giving it a delta of 67.4 the three scoop finished with an average temperature of 75.3 at a room temperature of 19.6 giving it a delta of 55.7 and the bladeless finished with an average temperature of 90.8 at a room temperature of 20 giving it a delta of 70.8 and although it was hotter than hellshawn it never did throttle you did it you didn't win or really come remotely close to winning but you created a fan based on some observations you made that performed exactly how you wanted it to and that's worth something at least to me but that puts the bladeless in last place the fission in third place the airfoil in second place and the three scoop in first and not only did the three scoop finish first in this group of fans ladies and gentlemen we got a new leader eric you've been in two videos with the same fan and now you lead the fan showdown you're winning so thank you guys for watching if you want to take part in the fan showdown.com make sure to head over to my thingiverse account to check out the drawing for the critical dimensions of the fans and then once you uh complete your design send it over to the fan showdown gmail.com i need at least an stl file and we'll see you in the next video [Music] you
