Power supply replacement

Post by brandstaetter » Mon Jul 09, 2018 3:22 pm

Hey all,

I built a Chinese kit with some quite nice components, but the included power supply is §$%&.Its fan is waaaay too loud and never stops running.
I saw on some other printers that the fan only turns on when necessary.

So... how do I find a power supply that has this feature? On aliexpress I did not find anything to help me filter...

Thanks in advance!

which voltage 12 or 24v?

i have a 24v which regulates the fan. (but it is not available by the seller)

I'd like to avoid hacking the PSU :D but if it's not possible to order what I want, then I'll probably do it

This is the 24V PSU I am using and its fan is PWM controlled. I don't think the product description says one way or the other.
