Where can I find the airflow and static pressure specifications for the 30mm cooling fan supplied with E3D v6 hotends? The fan on my hotend seems to be failing and I'd like to replace it with something quieter like a Sunon MagLev vapo bearing fan but I'd like to know the specifications on the original so I can choose a fan that will provide adequate cooling.
I guess using the power supplied should work instead or be good enough. Is there that much choice of fans of the same size?
