Hello, I was curious if there was a way to tell which size fan to use? I bought this pc prebuilt in 2015, ive replaced everything but the fans... I have no idea what size they are or how to find out.
 
Take the fans in the case and measure diagonally across corners. If you're lucky, it'll be close to either 80mm or 120mm, which are common. Otherwise the other choices are 92mm and 140mm. Ranges beyond those are rare.

EDIT: It was pointed to me that it's the edges, not the diagonals.
