HI guys, just installed the peek fan, not the original one, and it is really loud! and soo fast. how can i reduce its speed??

thanks

You can switch the peek fan on or off using the M42 command:

M42 Px S255 (where Px is the Pin your peek fan is connected to and Sxxx is the speed of the fan - 0 = off / 255 =100%) in my case, the command is M42 P6 S255

That no longer applies with the current firmware. The PEEK fan should be left at full speed.
