I have a Nevermore filter with 24v fans, would it be fine to connect them to the parts that I have circled on my Prusa MK4?

Or is that dangerous?

Like I said in my other comment

would it just be better for me to use one of these https://www.amazon.com/gp/product/B07C61434H/ref=ppx_yo_dt_b_asin_title_o00_s00?ie=UTF8&psc=1 with a laptop charger?

If the charger is a 24v powesupply, that would work. I would also suggest getting a switch to put in line so you don’t have to keep unplugging it- either a rocker switch or mini toggle.

Not sure how familiar you are with electronic stuff, but the fans I have are 24v and 0.1A my laptop charger outputs up to 6A that shouldn't be an issue right?

Volts need to match, nominally.

Your fans will only draw .1A from the supply- as long as your supply has enough amperage to supply everything running… your fine.

So I should be fine if my charger ranges from 19-24V? Or does it need to only be 24v?

[–] [email protected] 1 points 10 months ago

19 is probably fine. Voltage is always a bit inconsistent so the phrase they use is “nominal”- or “more or less”

[–] [email protected] 1 points 10 months ago

With a fan it won't be a big deal if the charger outputs 19-24V. Do you have a multimeter? Do you have a 24V source anywhere on the board? Using a laptop charger for 24V/0.1A is just way overkill. It'll work just fine though. You might also get some 24V LEDs to run off it too since you'll have all that extra current capacity.
