That's one of the three-pin plugs that I see whenever I look for an adapter. Three-pin mobo headers supply +12V, ground, and speed sense. Fan speed is controlled by altering the voltage on the +12V pin. Four-pin headers add a PWM (pulse-width modulation) signal, and this -- rather than voltage adjustments -- is used to control fan speed. The fan headers on my son's mobo are all of the four-pin type. (And it adds to confusion because the Molex connectors are sometimes called "four-pin," too.)

Do these come closer?
Also, what do you feel about the information presented here?

My fans have Molex plugs on the ends of their cables. I need something that converts these to 4-pin PWM plugs. Given the dearth of available options, one of two things is true:
- I am going to have to break out the wire cutters and do some custom work.
- Fans that lack PWM plugs aren't designed to work with PWM -- that is, they expect a continual if possibly varying voltage, rather than voltage modulated by pulse widths.

I would think that someone, somewhere makes what you're needing, though.
I'm guessing the molex connectors on your fans are male, what do you need for the four pin PWM connectors? My hunch is that you would need an adapter that is female on both ends, is that corrrect? By any chance could you include a picture of the motherboard and the headers in question?

Asus Maximus IV GENE-Z/GEN3. Example PWM fan header in green (ignore the error, Newegg's site always does that with Flash images in Rekonq on my PC, dunno why):
Rosewill Ranger-M microATX case. Enlarged image of Molex fan cable. Both fans have the same connector, a "hermaphroditic" Molex:

Those cables contain sockets to accept four-pin PWM plugs. What I need are cables with plugs on the ends. The lack of such cables leads me to believe that ordinary fans, like the ones in my son's case, won't work with PWM signaling. There must be something unique to the fans themselves.

Admittedly, I'm not fully getting the concept here. But I did try to help.
Best wishes in getting or making what you need.
