Solution
Depends. Some comes already with adapter or just buy one like

Instead of limiting your selection of fans, just get a good fan and then get the adapter (which is like $2).

As far as a "good" fan that completely depends on your definition/needs.
Would need to know what size, airflow, and noise needs are before we could suggest a good fan.

I would seriously recommend just getting an adapter or fan controller. If you connect it via molex only it will constantly be at full RPM and be super loud. That's fine if you don't mind the sound, but it will get irritating after a while.
