Fan 12v the mainboard duet3d wifi

Hello friends.
Question can we put a 12v layer fan directly? I read yes and no !!!!!

@sgk If you have a 24V supply, you will need a stepdown converter to connect the fan.

@sgk the image you posted shows a 24V-12V converter being fed into the fan supply select central pin on the Duet 2. this provides 12V on the fan pins.

Excuse me, I'm a novice, is the mainboard 24 or 12 v? Because when I install fans of 24 it works and 12v also then I am lost.

@sgk You can power the Duet Board with 12V or 24V...
It's depending on your power supply.

@cosmowave OK, thanks.
But then why when I plug in a 12v and 24v fan both work.
I have a 24v output power supply

@sgk a 12V fan may work plugged into 24V but wont last long. a 24V fan will often spin when plugged into 12V but will be spinning much slower.

@t3p3tony yes OK thanks very much
