Use Heater Output to run a berd air?

[kuhnikuehnast]

Hi there,
as I only use one of the 2 Heater outputs and my PWM-fans are running at 12V I got this idea:
Is it possible to use the 2nd heater output to run a berd air pump? So I could run the pump quiet easy at 24 V and the other fans at 12 V.

Remapping fans to spare heater channels is supported in firmware 2.02RC2. See the new A parameter of the M106 command. This is a temporary solution pending a more flexible configuration mechanism.
