Controlling Electronics fan using thermistor connected to E2
-
I am currently building a Hypercube and have all my electronics in the bottom in a closed enclosure. There are vent grills around the perimeter and 2 - 80x80 fans (24v /.14a each) in the rear of the enclosure for in-taking fresh air and 1 - 140mm (24v /.25a) fan in the enclosure cover for exhaust. I am wanting to know if I install a thermistor inside the enclosure and connect it to E2 (I am running a single hotend/thermistor in E1) could I thermostatically control the 3 fans off of the temp inside the enclosure. IE: when thermistor reads 25 degrees C the fans would come on at say 20% then ramp up if temperatures increase? I will also have a 30x30 fan (24v .06a) cooling top/bottom of stepper drivers connected to an always on fan port. Other fans are titan aero cooling fan plugged into fan 1, and a 50mm radial part cooling fan plugged into fan 0.

Yes you can do that.

You could also use the CPU temperature as a proxy for your case cooling.

@jaw8850 Quick answer - yes you can that. Longer answer, that's very similar to what I do - take a look at this post that I made on my blog some time ago - it's a bit out of date because you no longer have to define dummy tools but you'll get the idea. https://somei3deas.wordpress.com/2017/04/18/stepper-motor-and-electronics-cooling/

Excellent, thank you. Must of had brain drain, read that page twice so far and completely missed it.

Excellent, thank you! I'll definitely check that out.
