Hi all

Ive completed my Voron 2.4 and just had a question about the hot end fan noise. Im looking to replace it with a quieter fan but I cant find any docmentation on what minimum CFM the Dragon hotend needs!

Does anyone have any recomendations?

Alternatively would it start clogging etc if I turn it down to 70/80% in firmware as its currently at 100%.

Thanks in advance
More than 6 cfm is what the stock fans deliver.

It does depend on your filament. PLA is more sensitive to heat creep than ABS or Nylon, for example.
