ENDER 3 V2 SILENT FAN MOD | Step-By-Step Guide 

I thought the exact same. It’s wayyyy better than my videos. I still have a long way to go to get to his level

Not being able to produce videos of this quality first try is the reason why I haven't started a RU-vid channel yet, definitely not just because I'm lazy :)

You said it! For a first video, this is phenomenal.

Same for me lol

fashionista

Same!😂😂

Yeah, nice stylish gimmick @Randomecticly keep on

Thank you! I definitely will :)

I know right! Many guides out there are way too long and boring. Thank you!

Wrong. The app measure the content of total power spectral and the noise is bigger. As you say the fundamental frequency shift to lower value and is more pleasant to ears. This is because the stock fan have a higher pitch and normally higher pitch have lower power. But from a scientific point of view this is a total failure because we don't know if the static pressure of the new fans are better or worse, but if your metrics are only your ears then the measure from the phone are a stupid thing to do. If you don't like what you see with your instruments you always repeat the experiment after you found what variable was wrong. Another important thing is ¿why change the fan inside your PSU and board if you don't measure the result? I doubt the fan from the stock PSU are louder, but these is what you see when you have more money to spend and little brain to use. Sunon and Orion are top quality without doubt but we don't know what of all the changes improve the perceive sound in subjective way as this video claim. In regard of wardrobe changes we have a wise phrase in my country "aunque la mona se vista de seda mona queda".

Thank you so much! I was having the same struggle as you, that is why I made the video :)

Thank you! I am very pleased and grateful for all the great feedback here in the comments :)

Good job! Yeah, the switch from sounding like a hairdryer to something much quieter makes a substantial difference. Maybe I should change the fan in my girlfriend's hairdryer so I will get rid of them for good haha

@@Randomecticly Now after printing for a while with this setup, I am super happy. But there is one minor downside to it. I used a SUNON 24V DC 1,11W 40x40x10mm 11,9m³/h 5800U/Min 11,9m³/h Sunon MF40102V2-A99 fan from Amazon for the hotend and parts cooling. I noticed that the parts cooling fan will not properly run at low RPM. It will start to really turn at around 30% fanspeed. Below that it will just stutter. Thats not a big issue, but I have to keep in in mind, when I create a printer profile in the slicer which uses a fan curve that speeds up the fan every layer.

Awesome! Glad I could be of help👍 Did you measure the noise before and after?

@@Randomecticly No, but I and a few other people feel that the noise was reduced by about half. I recommend the silicone gaskets!

@@billsmith4932 hey man, can you download some the noise measurement app and measure the noise now. It would be good to know level of noise

Thank you so much! Your comment means a lot to me :)

Thank you a bunch! Most videos feel so serious so I thought i'd throw in some comedy :) I actually thought that these fans wouldn't be so much noisier than a noctua. But maybe i'll do another video were I change everything to noctua fans and then compare to this.

@@Randomecticly That would be interesting! Keep up the good work!

who doesnt love a fashion show

Thank you as well! Keep in mind that the part cooling fan doesn't spin at 100% the first and second layer so that is why it is quiet in the beginning. Also, the mainboard fan is not always on, only until it gets too warm underneath the printer :)

Haha I knooow:( I used an external mic for that part and forgot to change the volume.. But thank you!

Love and respect to you from Sweden! And thank you :)

the original didn't come with the silent boards. My original is far louder than the V2. Unless you are talking about the fan unit. Hearing the stepper motors compared to my V2 drives me insane

Hey doppelganger! I looked through your videos and subbed too! Good luck yourself👍 I saw your video and you are right, just getting rid of that loud noise is enough. Perhaps the dB readings doesn't show that but the printing is sooo much bearable to be around now. I'm thinking of doing noctua fans in the future to further improve the noise but we'll see. I'm happy as it is right now :)

thanks for the head up as i have a ender3v2 neo

Thank you! The purpose of this video was to actually use fans that are easier to install. They're not as quiet as noctua fans of course but they bring the noise down quite a bit :) Perhaps in the future i'll upgrade to noctua!

Thank you Robert! Yeah I used an external mic so that is why the freq became different :) I was thinking of making another video were I change everything to noctua fans, but because they lack the necessary airflow like you said i'm thinking of maybe skipping it. It could be dangerous if I were to print something under a looong time... We'll see tho😊

@@Randomecticly My thoughts exactly, I think If I was going to add Noctuas, it would only be for the PSU and mainboard. But I really like your fans and will stay with those for the correct airflow. Great tutorial again.

I did a similar upgrade and was also disappointed that the sound level did not drop enough, especially since this printer's loudest parts are the fans, so then I installed Noctua fans (for the PSU, motherboard, hot end and parts cooling). If you are going to go through the trouble of the upgrade, then don't make my mistake, just upgrade to the Noctua fans from the beginning. If you go with Noctua 40x20 fans you won't have airflow issues. However, the Noctuas are only 12V, so you need to install a buck converter with them to step the 24V to 12V, which is not a big deal. Well worth it if you really want something that is truly quiet.
