KPA 1500 fan speed at turn off

[Howard Sherer]

Wouldn't it be a good idea to keep the fan turned on in the KPA-1500 after
you power it off till the internal temperature reaches its lower temp?

 I just keep it on until the temp dies down.  If I'm in a hurry to shut it off I turn the fans on manually to cool it faster.

I use Node Red to control and monitor the KPA1500. I have written into the
flow to delay turn off of the amp when I click power off until the
temperature of the amp is down to 38 C. The fans are programmed to turn off
@ 39C.
This way I can walk away after clicking OFF and not wait for it to cool off.

Node Red is free and the amp can be controlled from any web browser.
