Official Creality New Upgrade Motherboard Silent Mainboard V4.2.7 for Ender 3 Customized and Non-Standard Matching,Ender 3 Silent Mother Board

I did not realize how much noise my old board made until I replaced it. Now all I here are fans.

Loudest part of the printer now is the fans, its great.

This is by far the best upgrade I made to my Ender 3 Printer. It was very easy to install and made my printing so quiet. Personally, it seems to work better than the 4.2.2 board that comes with the printer. Totally recommend this board! Especially if you dont like noisy printing.

Easy install just dont forget to flash it before trying to print

Burnt out and smoked soon as power was applied

Quited my noisy V1 Ender3. Easy install.

So, I was skeptical about the silent part of this. Yeah, whatever, my stock printer was quiet-ish. It wasnt annoying or anything, but OMG I was dumbfounded at how LITERALLY SILENT it is now. Like if it had a heart, Id check it for a pulse. The ONLY noise it makes is when it is auto leveling to find the Z stop. The only negative things Ill say, but I wont ding with a star is that it was a bit of a pain to find the exact setup I have (Ender3 Pro w/ BL Touch) firmware wasnt available from Reality, so I had to find one elsewhere. But honestly, this was the BEST upgrade I have done to my printer. <3 Thanks!!!!!!

This is an excellent upgrade for anyone who has any of the earlier Ender 3s. However, if youre not tech savy, you might want to get someone who is to install it.

Im happy with the print quality and the sound, but my octoprint let me know that the firmware on the board has issues with temperature monitoring. The issue wasnt present on the stock board, and its upsettting to know that if I didnt have an octoprint, Id likely never have learned of this issue, which seems to me like a potential safety concern. Also, the board has the fan connector in a different location and its not clear which of the two 3 pin slots is the one that was moved.

My printer was advertised with a silent motherboard and when I turned it on I didnt think it was that loud. I could have it out in the lobby and nobody could hear it from their bedroom. Then one day I accidentally knocked either a tiny capacitor or resistor off of the board that was essential to the Z endstop switch and my printer could no longer home. So I installed this board and WOW! When it started moving it was eerily quiet. Barely audible while youre right in front of it.
