Fan sizes

  Swampy 07:30 06 Jan 2007

Hi all. No doubt this is obvious when you know. When a fan is quoted as being, say, 80mm, is that the fan blade diameter, the diagonal fixing holes or the adjacent fixing holes. I can't find it stated anywhere. I have a case with diagonal fixing holes of 100mm, therefore what size fan would I need?

Fans are measured from the outside edge of the fan casing/surround, sorry don't have a fan handy to measure but would hazard a guess at 80mm.

This and several other references suggest that the size refers to the external dimensions click here
