An old working power supply is a power supply that has been well cooled throughout its life. Hi! A simple frame to hold a 24V fan onto the Prusa I3 MK3 power supply (see pictures). Not tested on MK1, MK2, but tell me if it works on the PSU frame. !!! The Original Prusa Power Supply is a 24V. To do this Fan Mod, you need a 24V Fan or a 12V fan and a DC/DC converter, see references below. Here's the fan I use and recommend: Very low noise and durability. Sunon is a fan brand you can count on, and it will hold the entire lifespan of the printer. 60x60x6 24v http://s.click.aliexpress.com/e/cmi5bMU But you can also use your 60x60 12V stock fan or another like this one: 60x60x15 12V http://s.click.aliexpress.com/e/vuOTDRS Quieter yet if possible. 60x60x20 12V http://s.click.aliexpress.com/e/bgouNMJI But you must use a DC/DC step-down converter 24v->12v like this one (this model is adjustable): http://s.click.aliexpress.com/e/bw61tIhi Happy printing! Renaud Not tested on MK1, MK2 because unfortunately I don't own these printers, but please report me if it works on your PSU frame.
