Electronics cooling fan
-
Hi
I tried to search a bit for my question but came up empty
Would it be possible to only run the fans when either heaters are active or when steppers are enabled plus 3 mins after they go off?
Or is that what popint 20 in the wishlist is about? https://www.duet3d.com/forum/thread.php?id=961&p=1

You could control the electronics cooling fan thermostatically based on the hot end temperature. That should have approximately the effect you want.

This blog post by deckingman is well worth a read:

uses a spare temperature channel to monitor the electronics and then thermostatically control a fan. -

i would glue the thermistor to the underside thou as it would be hotter than the top of the chip
has there ever been made FLIR pictures of the duet in action?

I stuck it to the top because when the fan comes on, I blow cold air on the underside. If the thermistor were stuck to the underside, it would sense that cold air and turn the fan off prematurely.
