I received my MK2 Extended Cetus 3D last week and I have had some great prints from it.
I have seen that some complain over the noise from the fan (at the extruder) and some have swap out the stock fan for a Noctua NF-A6x25 (5v) with an 3D-printed adapter to make it fit.
I have two questions you might can help me with:
- My stock fan model number is: NMB 04010SS-05L-AA. In this website: https://www.eminebea.com/en/product/airmover/fanmotor/dc/04010ss.shtml
they write that the noise from it is 21 dB.
According to this site about the Noctua: https://noctua.at/en/nf-a6x25-5v/specification
the noise from the Noctua is 19,3 dB.
That would not be noticeable. Am I missing something or do you have other fans that are louder (earlier model of 3D printer from Cetus maybe)?
- The Noctua has a much better airflow and CFM than the stock fan. (see above links again)
Stock fan: 0,14 m3/min = 8,4 m3/h = 4,9 CFM
Noctua fan: 0,486m3/min = 29,2 m3/h = 17,2 CFM
Is this an advantage for the Noctua or not? What can I win with this higher CFM? Shall I replace the stock fan because of this?
I mean shouldn’t the 3D-printer already be design so it is optimized? I don’t want to end up with less quality prints.
Please help me straight out these question marks.
