Hi everyone,
I have a Bambu Lab A2L and it is located right in my living room. The printer is great, but the hotend fan is just too loud for me to run it comfortably while relaxing.
I am thinking about a mod: I want to use a 120mm Noctua 5V fan with a custom 3D-printed funnel (fan duct) to direct the airflow straight to the hotend.
My goal is to get a very quiet setup without causing heat creep or clog problems. The last resort for me would be building a full soundproof enclosure, but I would love to solve the fan noise first.
Has anyone here tried a similar workaround or built a 120mm fan duct for the A2L hotend? Any tips or ideas before I start printing the adapter?
Thanks for your help!
There are already a lot of CPAP/remote cooling options available, I’d look at those before trying to build it from scratch - and a 120mm fan is always going to be wrong for this application.
