For a long time I was really skeptical of the silent board upgrade for the Ender 3 because how much quieter can a different motherboard really make the loud screeching of a print? A buddy of mine and I finally bit the bullet and decided to get the upgrade and we are still shook about how quietly it prints now. Every great once in a while I might hear a slight echo of a motor but 99% of the time while printing I hear nothing but the fans. Especially for someone who sleeps in the same tiny dorm room as the printer I must say if you've been considering getting the upgrade but aren't sure if it's worth it, you should definitely jump on it. Swapping the board took me less than an hour and is pretty easy as long as you double check that you're plugging cables into the right spot. Now that I'm realizing how quiet I can make it, does anyone think the noctua fans are worth it to help the sound even more?

tl;dr: nobody told me how good the silent board is so I will tell you, it is very good and quiet
