I am looking for a 12V blue LED fan and a grill for a purpose other than a computer. I am wanting to know what the sizes are for standard computer fans, I know there are 40mm-120mm sizes, but I am looking for something that is about 2-1/2 to 3" square maximum, is this going to be a 60mm or a 70mm? I can not find a conversion chart for these fans anywhere from mm to inches.

Thanks,

Computer fans are measured by their widths, as 1 inch is 2.54 cms = 25.4 mm.

So 2.5" is ~66mm and 3" is ~75mm.

ok so that leaves me to buy a 60mm or a 70 mm. I do appreciate your time, and thanks again for the information.

SoMdMusicianHere is one site you might try. I found several, but it seems most are carrying very similar fans.
