I need a hot end fan for my prusa MK3, i found these two similar looking fans on amazon, Can some one tell me if either is the same as the OEM fan.  Can I use either of these will I need to change the conector? I have no electronic experience so I want to make sure I get the right one, I can put a new conector on as long as i know which wires go yo whic teminal.

Both are the right size, but keep in mind that the OEM fan has a longer cable. You should get the 3 pin fan as the Einsy has 3 pins. You'll also need to crimp on some connectors, and extend the wires a fair bit. There are lots of images online to see the pinout of the fans.
