Noob question

[ennogs]

One of my case fans has gone. How do you work out what size it is? If I measure diagnonaly from corner to corner it is 110 mm. If I measure corner to corner lenght and breadth it is 75 mm.

So my question is which measurement do I use to order a replacement?

That sounds like an 80mm fan. Fans are measured screw hole to screw hole along an edge for size, not diagonally.
