Case fan sizes

[Matthew Graham]

I’ve seen plenty 120mm and 140mm fans but are there any smaller sizes?

Yes, but the smaller you get, the louder they are.  It used to be they were almost always 80mm.

Of course, those are just two sizes of many, what size do you need? 200mm? 180mm? 92mm? 80mm? 60mm? 40mm? There's tons of common sizes in various thicknesses. 80mm used to be the most common size.

This is one of the many examples of 80 mm fans:

20 years ago the case fan standard was 80mms,Today its 120/140mm.I'd never want 80mms again they are loud and don't even move the same air a 140mm can.

I have a little 92mm 4000RPM ripper that blows as hard, or harder than a 140mm iPPC 3K

 

It also removes flesh if you get too close, and it will blow your header if you hot plug it
