...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's work 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 here below...
Here is the fan i use and recommend
Very low noise and durability
Sunon is a fan brand you can count and that will hold the entire lifespan of the printer
60x60x6 24v

But you can use your 60x60 12v stock fan or another like this one
60x60x15 12V

Quieter yet if it's possible.
60x60x20 12V

But you MUST use a Dc/dc step down converter 24v->12v like this one (this model is adjustable)

Happy printing !

(not tested on MK1, MK2,, because unfortunatly i don't own these printers but please report me if it's working on your psu frame..)
