[Elecraft] KPA1500 fans not working in auto mode

[Dave]

I do not remember the exact values but the latest firmware changed the start & stop points for the different fan speeds. If it had gone to 50c without the fans turning on then I would definitely be concerned.

Maybe someone from Elecraft can post the temperature crossover points for fans to increase or decrease speed. There is also a dwell feature where you can add delay before fans decrease in speed when cooling down.

I’m happy with fan performance of current firmware.
