@@mlee6050 I have several fans and they have mixed directions and do not follow the crossing. They shape of the blades is better indicator but there's also an arrow symbol printed outside the duct that shows the direction.
I just recently built something very similar (3x3), but built it into a collapsible/nesting type extension arm with a detachable carbon filter, it folds nicely and fits into the bottom of my toolbox when not in use and for portability. I use it as an overpowered fume exhaust (because I'm real paranoid about lead fumes when soldering, but refuse to use leadless solder).

I dont comment on youtube videos but this one is special. This has been the subject of much subconscious activity that occasionally forces itself into my conscious mind and distracts me. When I saw the thumbnail of the video it was as if someone had been inside my head rummaging around. So, that said, I also imagined the little metal squares with nuts and bolts. I also took that idea to the point of a sheet of metal on both sides with large holes for the fan to blow through and the small holes at the corners of the fans to bolt or even pop rivet then together. What my mind kept coming up with was a wire routing that went into the spaces between the fans as there is just enough space there to put all the wires out of sight. Finally, my brain told me, all the stickers at the center of the fans should be pealed and replaced with round black stickers to improve appearance. None of this is intended to be criticism because I never actually built my idea and you did. This is just intended to infect your mind, which seems to be similar to mine, with the ideas I had for years in hopes that you might build it. I think this idea could be taken to the point of a saleable product with a few finishing touches. Great work!
I have a question: How much air does this move, compared to a box fan, allowing for the size difference? If I made a 20 inch square of fans, would it move as much air as a 20 inch box fan?
for this sort of thing, i would recommend Noctua NF series or Aerocool DeadSilence (all 140mm) if you want quiet, but they are like £15 each (or your regional equivalent)
in a computer, premium fans are actually a really good thing if you have the room for air flow as they are optimized for pressure rather than just moving air, can drop the temp of your components a lot, however, open air solutions i cant say
if you hooked them in series you would need 192V which can easily be achieved with 120V mains through a bridge rectifier and capacitor gets you 170V each fan would get ~10.6V but thats good enough
That will not work. The problem is that the fans each draw current in pulses. If you could keep all the pulses timed so that all fans wanted the same amount of current at the same time, you could do it. But you can't keep them in sync. I have done 2 fans in series, and it didn't work well until I added a capacitor across each fan, to even out it's current draw. I also had to use matched fans. Same brand, size, and current draw. Then it worked fine, but I don't think it would be safe to try this with any 120 volt mains power, even if you did have enough fans to "share" the high voltage. The problem is if something goes wrong and they don't share and one fan gets hammered with all 170 volts. It might be okay if you lived in a house with concrete block interior walls and had no combustibles nearby. Other than that, put the fans in parallel and then you don't need capacitors, or matched fans. You can easily get a 12 volt power adapter online for a very reasonable cost. I have also seen adjustable voltage units that would let you adjust the fan speed easily.
We did this a few times with left over fans. It makes a hell of a noise unless fed 5-6v instead of 12v. And if you make the mistake of chaining them, you'll cut voltage by half every step, remember that.
This rig uses 38.4 watts of power. How many CFM? I can't help but think that it will circulate more air per watt than a comparable box fan with a shaded pole induction motor. My 20" Lasko box fan uses 55 watts on lo, and 96 watts on Hi. It does, however, produce quit a bit of airflow, though I don't have an accurate way to measure it. All I can think of is a side by side test. Your rig isn't quite that big, but it does't use nearly as much power, either.
Hey, you reckon I could make my own pillar lugs and mount my motherboard on this? Effectively using the wall of fans as a case wall? (without the rest of the case - sorta like a test desk?
I made one of these two years ago. I had and still have tons of those fans. perhaps the next project: 64 floppy drive music. all drives have their own midi sequences.
Did this about a year ago with 4 80mm fans. Works, and not nearly as loud as you would expect, especially considering other box fans you may encounter. Plus you end up with a unique household item that you built yourself!l Win-win!
thanks man, I'm planning to attach them to my DIY laptop desk. 4x120mm fans is good enough. btw how to know between + and - of the cables, and will it be ok if i plug it right into power outlet or power supply is the safest way?
Generally there are 2 kind of fans: 220v (ac) and 12v (dc) voktage. Check the voltage stated at the center of the fan. Then, for 12v fan, the positive usually have RED cable, negative is BLACK cable. If your fans is 220v, it is save to plug them directly to powerline on your wall. There is no + or - cable for 220v, you can safely plug the cables without worry of their + ot -. DoNOT plug the 12v fan directly to powerline at your wall, they need DC 12v powersupply, or you can use your dad car battery, it is 12v. Hope this help.
So i was considering doing some type of Desk mod with fans, yea it gets hot in my room and ya know where i needs that fresh air :3 Anyway, ive got 1 12vDC - 0.37amps 120mm fan, if i were to do 18 just under 7amps for my battery would this work? Not gonna really do this, was thinking of around 10 fans which is around 5amps in total. Would this still work decent with my battery? Im doing this off of a Solar Controller/12vDC-7A Battery so i wont really be pushing that monthly bill xD
I admire your patients with your project. You make awesome things, I love the master fan of fans ;-) Just a tip, I wonder how would the transparent ones look with a subtle led lighting.
Request: Can you append video with some example of the breeze such a configuration creates? I like this idea but wanted to see a demonstration. Maybe putting in front of a pinwheel at 3 feet or just holding a strip of paper.
does ne1 know if u can separate the yellow n black wires of CPU as in to wire each fan separately instead of joining all the yellows n blacks into one big connection and fans the same instead of neat ones on each fan , please can someone answer this question , thanks Peep's
This is pretty pointless. a 20" box fan can produce 2500 CFM (according the mfg) and a cheapo (Rosewill) 80mm fan pushes ~32CFM. You can fit about a 6x6 grid of PC fans in that same footprint and 36x32 is only 1152 CFM.
i want to say this is an unimpressive video, but im more than likely actually going to use this for my windows, now only will it keep my home cool but it'll be a death trap for any flies trying to get in
I would but a big piece of modders mesh on the front and back sides of the fans too protect them from getting damaged, and instead of these small 80mm fans get like 4 220mm fans that can push the same amount of air at a lower speed, and with less energy needed.
+turtle79070: Yeah, that seems like the one killer app for this multifan. The fans I've seen that are designed to go in windows generally just have one or two fans in them, and then use a piece of plastic for the rest of the height, whereas with these you could have fans across almost the entire height of a window, and you wouldn't need to have your window (and vertical blinds or curtains) open more than 80mm. So did you go through with the project for your windows? How did it work out?
Before this video I wathced a LinusTechTips video about fans and cases. The cheesy pun amount in that case messed my head and I have no idea what the computer fan fan was talking about in this case.
1. Not all places have air-conditioning 2. I think his application is mostly to reuse old/inferior stock fans that get replaced 3. This rig is portable and can be powered by many sources. Mostly though it seems like using stuff that would otherwise be thrown out
What a Great Idea, I to have many fans & now that i've seen this idea, I now feel sure that I can do Likewise. Here is an instant Idea for the U-Verse owners out their. take a Single 120MM Case Fan & Mount it down on the top of your control box, The one that turns your unit on or off, & if So Equipped, (Like Mine is) You can use the Front USB Port to Power the Fan, Thus Cooling Down your FAN-LESS Unit. We had already Burned up our first Fan-Less box, & the Salesman told us that none of their units came with a Fan to Dispel the Heat that the box Generates..
you can make a entire pc case out of it. then replace your case with just walls of fans. it will be retarded and probably wont do anything, but it will look sick
I know this is very late, but wouldn't it be much better to just take much larger fans (like 4 240mm fans)? Since it would provide a much higher contact area with the air, so more airflow and much quieter.
No, they have to have the same voltage as power adaptor, so all 12V in this case. But you need to check how many Ampers your adapter provides and add Amper use in your coolers to make sure that they all don't take more than your adapter can feed them.
also, rather importantly, make sure they're all flowing in the same direction lol
@burnzy3210 that easy if know fans have plastic crossing over one side and not the other and air goes through one way then
@@mlee6050 I have several fans and they have mixed directions and do not follow the crossing. They shape of the blades is better indicator but there's also an arrow symbol printed outside the duct that shows the direction.

Quiet ? I doubt it. Unless you spend a fortune on quiet fans, they're gonna be pretty loud, esp. if they're small.

I have a small 15x20 window. This is a good idea for a window fan

if you use 4 wire fans and connect the blue to Ground they run at low speed, almost silent!

you wired in series, wire in parallel. Make sure both positives from the fans are on the single positive from the controller, (same for negative side)
