Most will do. However those attached to molex plugs are unlikely to have the sense wire, and 3 pin fans with the yellow wire missing probably exist.

yeah they do i have one in a old 90's tower with a very old celeron processor in there, that fan is permanently at full speed. I started that one up the other day still works i opened notepad and then a browser and registry cleaning tool i had to wait about 30 seconds for it to open LOL can't believe we coped with computers that slow
