A lot more quiet than my Ender 3 stock fans. Also blows a nice amount of air to my e3d v6 heatsink. No critical flaws so far!

It is even louder than my Ender 3's stock fan. It does move lots of air and good static pressure but no way it measures 20dba. More like 40dba.

Sunon makes excellent quality fans used all over industry. I purchased three for replacing 4010 fans in a 24v 3d printer to improve airflow to the electronics and hotend. They move more air than 4010 fans and are much quieter (Not silent, but not unpleasant) than both 4010 fans and cheap 4020 fans from Amazon. If you have the space for the extra thickness and need good airflow without excessive noise, look no further.
