Case fan size

August 24, 2005 at 06:12:41
Specs: WinXP Pro, p4 2.8GHz / 1GB DDR 400

The bearings are going out in one of my case fans, my computer sound like a can opener when I first boot up. When I looked for a new one I noticed that they have different sizes, 80mm, 88mm, 90mm, ect... When I look at the fan that is failing I can't find a measurment written anywhere and looking up the manufacturere and part number didn't help. What do these measurments refer to and how do I properly measure the one I have?

I am treated as evil by people who claim that they are being oppressed because they are not allowed to force me to practice what they do.

If you are replacing an existing fan, measure the diameter of the blades. If you were fitting a fan where there was non before you would measure the distance between two adjacent screw holes and round down to the nearest 10mm. I can say I have ever seen 88mm fans. 80 and 90mm is the usual sizes.

If you are in a metrically challenged conutry, check out this site:

To tau_titan and Stuart:
Thanks for the measuring info. There was an 88mm fan on NewEgg.com but it may have been I typo.

To Rick McNabb:
Thanks but I’m not metrically challenged. I just didn’t know what component to measure, the fan blades or the fan casing ect…

To mvoltage:
Thanks, I’ll try oiling the fan before buying a new one.
