So, the way you go about this -- with the buck converter -- makes people think they need like a dozen buck converters. Since all of the fan, hot end, etc inputs are NPN transistors, you actually just need to lead a positive lead to everything that needs to be switched at a lower voltage, and then tie the negatives of those devices to the switched end of their respective ports. This will allow you to use 1 buck converter for your _whole_ system rather than a bunch. Edit: Nvm - you KIND OF cover this later on with the PWM fans, but maybe people will figure that out.

Ah heck let's give out a real secret. A LOT, and I do mean a lot of fan noise is due to low pressure chop. As in the fan blades entering into areas of low pressure caused by the drawn air flowing by obstructions. Ever notice how most of these power supplies have a terrible metal grate put in front of the fan? Don't touch anything else in the supply, take the lid off and undo the fan, cut out that silly grate into a hole a bit larger than the fan opening, then reassemble. Then notice that it's a whole crapton quieter since you don't have silly, poorly designed obstructions creating a huge amount of low pressure zones right in front of the fan opening. Part of why putting Noctua fans here makes it quieter is simply their slower flow, but you can accomplish a lot just by removing this incredibly poor choice in design. Yes, keep your fingers away, but that's a small price to pay for a lot quieter environment. Obstructions in front of a fan are supposed to be X distance away so the airflow recovers and doesn't have low pressure zones creating unnecessary noise, that is very basic design guidance. X is not 'right in front of the damn fan' like they do on these supplies and a lot of other cheap equipment.

For anyone wondering about connectors, switches, relays etc and the markings for the pins, NO, NC, C, O (normally open, normally closed, closed, open). Normally open means its open until you use the trigger mechanism, which closes it (allows current to flow), and normally closed usually allows current to flow but doesnt when triggered. C and O (closed and open) means they are permanently open or closed. Often you find C and NO next to each other, meaning you can have power connected to NO and the thing you want to switch connected to C, or the other way around, to control it. This took me far longer than necessary to understand, so I figured I'd take a shot at helping anyone else who got confused by it

Just a little info on the noctua fans. I use for part cooling a special fan duct with 2 axial noctuas one beside the other wired in series giving me 24volts. I tried it with the 20mm thick ones: it does not really work, because they only switch on at 50 or 60%!!! i use for 2nd layer 10% and adding 10% every 2 layers. On the otherhand it works very well with the 10mm thick ones!!!! wired in series they switch on at 5% (ok.. that is very low and you can see them turning) but they are perfect at 10, 20, 30, 40.... % . so i think it is important to test the fans at different percentages. I think with the buck converter it will be the same, the 20mm one not switching on below 50%.

Axial and blower fans aren't that simple. Blower fans do not simply move more air, in fact they move less air than axial fans of similar size. Blowers move air by creating high pressure, whereas axial fans move air through a large cross section but at lower pressures. Axials perform better when there are no obstructions in the airflow path, and blowers perform better with sub-optimal paths. So, technically, by using a fan duct for the hotend, you are constricting the path, but the focused stream of air may make up for the reduced airflow, and thus you do not see any clogs. Moreover, you always see blowers used for part cooling because of the indirect path used to point the air right below the nozzle

I'm very careful when choosing buck converters to drop voltages from 24v to 5v. Some of the cheap ebay versions without heatsinks can get stinking hot because they're not designed very well, and the advertised specifications can be downright lies. The higher the voltage drop between supply and output, the hotter they run. I recommend running a spare fan from the proposed buck converter for 1/2 an hour, and check it's temperature before deciding whether to fit the converter to your printer or not.
@ef3675

These devices are generally designed quick&dirty from the datasheet's typical application directly. It's doesn't necessarily mean they are "lying" or "not designed very well", most often than not people don't have the proper knowledge to know what kind of additional limitations these devices have. Yes, the more you buck the more inefficient it gets but mind you that's an unavoidable quirk of switching power converters (24V to 5V at 3A is only 80% efficient, which is quite some heat generated for and SMT component), as they exhibit very strong efficiency vs duty cycle characteristics.

I've often wondered how good a cooling solution you could get by using some silent, high-static-pressure fans mounted to the frame and pipe the air to the head. That would remove the size and weight restrictions, but I'm not sure how well having a large hose attached to the cable chain would work. It would be a good idea for an experiment, I think. It would be content, even if it wasn't better than mounting fans on the head.

When fan works with minimum vibrations the fan livespean will increase because bearring stress is minimal..

Could be a number of problems. Initially I would look into the minimum layer time in super slicer which I believe is in your "print" settings, it can and will pause your print to wait for an arbitrary time set by that setting. There's also temperature, if bed or nozzle drop too low below the target, it will pause to wait for the heat to rise. I ran into that one when I over-tightened the screw holding the thermistor in place on my hot end. However my machine beeped profusely to alarm me something had failed despite never doing that for any other faults. Stepper motor overheat can be a problem if your machine is monitoring for overheat conditions. As far as I know, this requires the steppers to be connected in UART, otherwise they fail in isolation meaning everything else keeps going as normal. Could just be overloading the firmware with commands. In the "printer" settings you can find a setting called "processor limit" and adjust that downward to lighten the load. Default is 1500 G1 per second, this would be troublesome for say my Ender 3 Pro that only realistically handles 200 G1 per second before it gets overloaded. My Ender 3 V2 however is fine with the default and after a recent foray into paging, seems a very conservative for your typical firmware configuration. Hopefully one of those gets ya on the right path but there is certainly a lot to it. Make a guess, research, perform test based on what you find and you'll eventually arrive at the cause. Forming a solution can be very difficult if it's a firmware config problem and your not proficient in C or C++.

Probably should have mentioned the BrissMoto fang option too. I run two of the thicker (Noctua NF-A4x20 FLX) fans for the hotend and part cooler, as well as Noctua 80mm (NF-R8) for the PSU and mainboard. Wired exactly the way you have it with fan negatives going to the mainboard instead of to the buck. Makes it nearly unnoticeable while its running aside from a tiny bit of driver noise from my ender 3 v2. It sounded like a jet sitting on my desk before.

Why aren't you recommending that people buy quiet 24v fans? There are tons on RS Component/digikey/equivelent just use the filters 24v and sort by noise ascending. Noctua + buck converter is so much hassle and extra complexity and good 24v are just as quiet and move more air. Instead of repeating the same tired advice please do some actual research on what is actually the best option...this is supposed to be your living producing advice videos?

There are some very nice Sunon 24V MagLev fans that are a nice easy swap out for the stock ones. Higher CFM, lower noise than the stock ones too. (this was compared with the stock ones on my CR10v3)

I was having issues not being able to regulate speed with buck converters, I like this idea, my solution was dual 12v part fans in series off 24v, so far it's working out great, been getting better results with petg now

I run my Ender 3 V2 in a creality enclosure that has a small fan and piping to move any fumes outside the house and i find this also deadens the noise of the fans . I never understood the fascination some have with trying to make a totally quiet printer especially now we have silent drivers - the sound of any type of machine running is music to my ears and i would rather listen to a noisy printer than the next door neighbours dog barking !

In my case it's not because of me, but because of the girlfriend
