1. Bambu Lab Chamber Fan 24V * Rated Speed : 4800 rpm/min * Max Air Flow : 92.56 CFM 2. Noctua NF-A9 PWM 12V * Rated Speed : 2000 rpm/min * Max Air Flow : 46.40 CFM

@Mastermoussa 8 месяцев назад

Doesn't really seem to matter. Double the CFM and only 1°C difference (or in some tests even less) with such a small chamber seems strange. I bet the real CFM (and not only the one on paper) are much closer together. *But it actually makes sense as the CFM shows the airflow and with a filter in front, high airflow fans are the wrong choice. You need high static pressure. So as I said both fans obviously perform very similar is this usecase and the Noctua is just much quieter.

@LachskoenigIV 6 месяцев назад

I'd be worried if the stock one doesn't provide higher static pressure. Noctua fans are not useful in front of a filter. The static pressure is too low, they are not designed for that.

Problem for me is trusting cheap fan testers. Testing fans by just holding up a meter isn't a very good setup. So it is a matter of "Do I spend money just to produce flawed data?". Sometimes I can justify that because some "flawed data" at least points us in a direction, but I don't know about fan testing like that.

@odj310388 Год назад

Funny you found the machine switches from 100% speed to 40% speed once it recognised the slower fan, I've taken to switching my stock fan speed down from 100% to 40-50% once the printing starts to quieten it down. I've found the same as you with the Noctua that it keeps the chamber cool enough at only 40% -50% speed and the noise difference is considerable. This is using PLA at 220-240 temp and bed at 55 btw. So if people don't want to go through the hassle of changing it out I'd recommend this quick fix instead of just lowering the speed once it starts.

@ryanlandry8214 Год назад

I received my X1CC back in August. It wasn't very loud at first until some later firmware updates so I'm sure it ran a round 50% at first and I did 3.5 hr PLA prints on the cool plate with everything closed no problem.

@francisbeland8959 Год назад

I just saw your post and while I'm printing I did the test to lower the chamber fan to 50%. It's effectively much less quiet. What I noticed is that when the chamber fan was at 100%, both the part fan and aux fan were a 0%. When I lowered to 50%, the part fan was started at 100% and the aux fan was started at 20%. I don't understand as I always thought that PLA was using a 100% part fan. Anyway, these fans are much quieter than the chamber fan so the overall noise level was greatly reduced. Thank you

@andyvannort2743 Год назад

But if the stock fan at 100% cooled roughly the same wouldn't the stock fan at 40% cool considerably less? The noctua is a better design allowing it to have better cooling at slower speeds

@odj310388 Год назад

@@andyvannort2743 bambu stock fan has cfm of 92 at 100% speed, this is down to 37cfm at 40%, 46cfm at 50% and 55cfm at 60% speed. The noctua at 100% speed has a cfm of 46cfm. So yea it is more efficient as the system recognises it running at 40% rpm of what the stock bambu one would be but running the stock bambu at 40%, 50% or even 60% considerably reduced the noise (which is the goal) and keeps the air flowing out. 👍🏻 I’ll be honest I’ve switched from 40% speed up to 60% just to be on the safe side.

@MandicReally I had the RPM issue on a QNAP when replacing YSTECH fans with Noctua. The issue comes from the peak-to-peak voltage in the RPM signal. You can fix it by putting a resistor across PWM and Tacho/RPM. In my case it was 6.8kohms. Easiest way to find out is to put a variable resistor in.

@almostalphas Год назад

Can you elaborate on this? You're referring to the issue with his fan showing 40% on the display when it's actually running at 100%? And that can be resolved by putting a resistor across PWM and Tacho/RPM? I'm not super experienced with this type of electrical, so just follow instructions to a T and try to pick up bits and pieces of knowledge as I go.

@halsaresnowpaw522 Год назад

Thanks for the video. It gave me some things to think about. I am printing ABS and the smell was getting pretty strong in the room. With the talk about your new fan effecting cooling, I decided to try an experiment to try and force some of the fumes through the filter. When printing with ABS, the exhaust fan is turned off. My chamber was showing a temperature of 51. I turned the fan on to 20% and an hour later, the temperature was still 51 and the smell had decreased. So I tried the fan at 40% and the temperature dropped to 48 with the smell about the same. Set it back to 20% now. Will have to modify the GCode for the filament to run the fan at 20% for ABS from now on.

Noctua fans are one of the best inturns of how quite it is and the airflow you get, but just like many have experience on moding their hotend cooling fans to noctua fans and experience clogs it is because yes they are good but their airflow are not great. So people who want to try out noctua fans need to be careful of temperatures see if the noctua are sufficent enough espcially on eletronics cooling fans if you replacing them on any machine.

@theyehsohz Год назад

I happened to do this yesterday just for the control board fan since the knocking finally got so loud that my wife couldn’t stand it anymore. I opened it up and saw that the fan just wasn’t spinning and knocking super loud. I went through the same deductive procedures, I decided to just cap off the white and light gray wires. The sticker on the fan hub was oozing from the melted adhesion and just lifted off. It seemed fine to just have the noctua a4x10 just run 24/7 to cool the heat sink. It should just circulate the air inside the chamber (?) I’ll have to observe and see. I looked into replacing that 24v 92mm fan but couldn’t make heads or tails on how to approach it so I just left it stock for now.

@WyvernDotRed Год назад

Someone I've been chatting with made a similar Noctua fan upgrade for the cold end fan. But the fan was PWM controlled for some reason (Makerbot Replicator 2 clone, keeping the board for now). And the combination of the buck converter and PWM made the entire thing reset or glitch out. (we solved it by powering it with the always on control board fan header, the switched output will be used for part cooling later) So if the chassis fan has PWM too, this might be a very problematic upgrade.

@YeeKongChan Год назад

Does the exhaust from the MC fan have to vent inside the control space, which might be used to help heat the enclosed printing area? I don't have mine on hand to see if there is any area that crosses over to do that.

@paulmilne3038 Год назад

It never occurred to you that the noctua fan might affect the cooling. Well that’s a surprise as I thought everyone with experience of noctua fans realised that one of the reasons it’s quieter as it’s known they have less airflow. I have been considering this and thanks this gives me some ideas/suggestions

@rhencullen Год назад

The 92mm Bambu chamber fan is a 4800 rpm fan shifting 92.5 cfm with a lifespan of ‘over’ 20k hours at 40 degrees C. The Noctua NF-A9 PWM is a 2000 rpm fan shifting 78.9 m3/h which equates to 46.4 cfm so it’s half the Bambu speed and half the cooling, but is rated for over 150k hours of use. Half the cooling probably explains to 2 to 3 degree chamber difference compared to some of the Bambu original fan quotes of 6 to 7 degrees, while the speed differences of 2000/4800 equates to the Noctua running at 41.66% of the Bambu original fan speed. All the same, I’m seriously considering this same upgrade myself. The Chamber fan bearings are starting to sound rough after 4 months of (continual) use. The 40mm MC fan failed 2 months ago, and though Bambu sent a replacement I elected to use a Noctua NF-A4x10 to replace the stock Bambu MC fan blowing through the heat sink vanes, with a second NF-A4x20 mounted at the side of the poop chute and blowing directly onto the flat of the heat sink and on the MC board itself. I’ve also got a printed baffle mounted to the rear of the case using N42 magnets, which drastically reduces the fan sound when printing.

@MandicReally Год назад

My replacement 40mm already sounds terrible and will be getting the Noctua treatment soon as well.

@rhencullen Год назад

@@MandicReally was that a Bambu replacement ? I’ve seen a few specialist articles now all saying that the MC fan is badly positioned to cool the MC heat sink, because the fan design creates a cone of moving air expanding out from the fan, and so doesn’t provide as much cooling directly in front of the fan as it does if it’s offset a little. I ended up replacing the stock MC fan with the Noctua 40x10 5v pwm then I also added a second 40x20 5v pwm fan next to the purge chute blowing onto the face of the MC heat sink.

The video makes it clear that it doesn't seem to matter all that much in this configuration, as a 1C delta is barely going to make a difference. Even if it did, you could just over-volt the noctua fan. I've been running mine at the raw 24v from the fan header and it's been perfect. It likely makes up, at least a little bit, for the low CFM at 12v.

@nicolasdarkdark Год назад

Sure it’s quieter, but if it doesn’t blow as much does it really matter? You can run the OG chamber fan at 50-70% to severely reduce the noise it makes

Interesting mod, even that I don´t own one of these printers yet, I think I will soon 🙂 I don´t find the fan confusing, but maybe it is because I am a mechanic, and see things differently, and maybe I am wrong, but to me it looks simple. Pla needs lower temp, therefore top off, and a fan to push fresh air in, you can not push air into a closed chamber, you need to let the air out to get circulation. And the filter - ask any mechanic or painter, they will tell you it is because when you stir up dust, it will set in the wet paint or in this case, the wet plastic, the filter is there so you don´t get impurities in the finished product.

@MandicReally 5 месяцев назад

The filter on the "Chamber Temperature Regulation Fan" is a Charcoal filter ONLY. It has no other filter media in it. So it doesn't act as a particulate filter the way you have in a paint booth. I'm a former Auto-Tech & Custom Car Builder, our paint booths were sealed shut. Heck last shop I worked at the painter would tape the doors before he sprayed to reduce gaps & hose down the area outside of the door to prevent dust from kicking up. The only entry paths for the air traveled through filtration to get into the booth. The Chamber fan on a Bambu Printer draws air in from gaps around the frame & door. As such it wouldn't do as you say, it would actually draw IN particulates from the surrounding environment. The fan draws in cool outside air and expels the hot air out the back of the machine. It does that job just fine to reduce chamber temp. But its use of a Charcoal filter is just... flawed design. Materials that NEED charcoal air filtration, need higher chamber temps. It should recirculate back inside of the chamber to maintain the heat. To make it really functional it needs a flap to direct air like a cars HVAC system. Recirculate for higher temp materials, and expelling it out for lower temps.

Trying to compare the main board in your video with the one I have in the P1P, they look pretty much the same layout, with the exception of an empty header on your board that doesn't have a header soldered on for the P1P. That to say, there is no board cooling fan on the P1P. So assuming the drivers are the same, and the firmware isn't cooking the X1 more than the P1P, probably don't even need that fan. Which as you mentioned, doesn't appear to be doing much anyway.

@97JoMiller 4 месяца назад

I purchased all the parts for this because my chamber temps were sitting at 39 with the chamber fan turned down to 70% so I didn't hear the fan roaring during the prints. I was hoping I could run the Noctura full tilt and I'd get better cooling but after doing a bit more research, I have a feeling even running full tilt, it's not as much air flow as the Bambu fan has running at even 60% so this probably isn't a good mod for me considering I'm wanting a quieter experience while cooling more. I have installed some fairly large risers to keep the glass off the top and some small fans to help with air flow and now I'm sitting at 36 while printing PLA... Do you think this is cool enough to combat the whole extruder clogging issue that I've been having? Running hot end at 220 and the bed at 60 for first layer then 55.

You could just add a buck converter to the original bambu fan to achieve the same effect.. Noctua fans are less noisy because they spinning slower, no magic. If I print pla or petg I just open the door or the lid and it gives better chamber cooling, than this rocket fan. You can turn them off completely in the slicer settings

@bujin5455 Год назад

That's really not true. Speed is part of it (but nowhere nearly all of it), it's also partly the design of the blades, as well as the motor assembly. You can see this for yourself if you test other fans like for like against Noctua. You can easily see the fan runs smoother, and even when ran at the same RPM, the Noctua fans are quieter. (Noctua does offer 2k and 3k fans, and they are still considerably quieter than other fans at the same speed.) BTW: Noctua also works hard to optimize CFM for a given fan speed, so they often get more cooling done at the lower speed.

@Mad_Catter_ Год назад

Yes because you obviously engineered the fans at Noctua and know it all. Never mind the patents they hold, the blade designs they fund research for, the motors that other fan manufacturers don't spec for due to costs, the dampening pads that most fans don't have and the material make-up being dissimilar in many areas.

Greta job ! But besides the fans, one significant source of noise is the motors. To you think you can dampen them ?

@MandicReally Год назад

I think it is more the mechanical system in general that is the primary noise source and don't really see much to be done about that. Fast printers are just going to generate noise. My Vorons, FLSun, and Re-AniMaker all have their own loud points. The Chamber Fan noise was the most unbearable sound personally. I work near the machine and have gotten used to the sound of it printing, but the sound of that Chamber Fan was always annoying.

@_Xantras_ Год назад

I see. Do you think lubrication of the bearings has a role in noise ?

@MandicReally Год назад

@@_Xantras_ The X-axis uses self lubricating bushings. It is possibel the Y axis ones are making some of the noise but I don't think that is the primary source.

Cheap DIY it just slide the OG fan ground/power and use the buck converter to stepdown to 12-23volts for optimal noise/cooling to your taste. OR just ask Bamboo lab to update the firmware that allows you to control the fan. Easy Pease!!!

@martinsmith2948 Год назад

Try taking out the carbon filter and see how much more airflow that lets through, it's probably blocking a lot of the airflow, and that's why they had to go with such a loud fan just to get it to work a little bit. And since like you stated, the filter does nothing on the material where it would be needed since the chamber fan doesn't run. Seems like a marketing gimmick lol

@exodous02 3 месяца назад

I live in an apartment complex and can't have a loud printer. I've been waiting for someone to make a drop in replacement, I thought it would happen since this printer is so popular. I notice the firmware that quiets the printer still has the fan really loud. I wonder why they just don't use Noctua from the get go, that would only add so much per printer when they buy fans in bulk.

@tombo7719 11 месяцев назад

the aux fan does the same.. goes to 100 then down to 30% or whatever. That is with a Bambu part on a P1P upgraded.. FYI, think you are right about how it commands the RPM. Also chamber fan page at Bambu says the stock fan is 4800rpm. FYI.

@Soundwave857 5 месяцев назад

Be aware buck converter will pull as much A needed to always give the set voltage, i fried a mainboard like this befor. set the fan speed to 1% by accident instead of 0% and overloaded the mosfet. In case of PWM not an issue but a big issue with voltage controlled fans

Noctua is actually selling 24V fans from their industrialPPC line. You won't need a step down circuit for them as they operate between 6V and 30V.

@MandicReally Год назад

Only in 120/140mm sizes. No 92mm ones, so you’d have to design an adapter to mount it in this use case and modify the back panel of the machine. Or have a fan having off the back.

The Filament G-Code for ABS in Bambu Studio doesn't enable the fan at any point (during or after a print). And they only just added the manual ability to toggle the fan on and off last week. That would in fact make sense, but Bambu doesn't use it that way.

I would be concerned about the thermals of the electronics. Most of them have some type of shielding from the chamber air (though not a lot in some cases). Even with other machines it is usually recommended that your electronics not be enclosed in a chamber with the heat sources. It is part of why I've not encouraged doing that when folks have suggested it.

@@KingShinobi82 could duct air in from outside the chamber to a fan on the back panel blowing right on the board. But I mean more than just the board I showed. The X-1 uses a split up electronics system. That "Mainboard" isn't actually the main control board of the machine. There is one inside of the chamber.
