I'm experiencing some unusual difficulty looking for a manufacturer part number for the connector shown here:
- http://www.moddiy.com/products/modDIY-Male-4%252dPin-(3%252b1)-PWM-Fan-Connector-(Molex-%232510)-with-Pins.html
- http://www.performance-pcs.com/male-4-pin-3-1-pwm-fan-connector-molex-2510.html
- http://www.bizrate.com/system-cooling/oid4026851578/merchant/
- http://1088992.en.makepolo.com/products/Male-3-Pin-Fan-Extension-Connector-p87525796.html
.. which is found on computer fan cable extensions.
There are 3-pin versions and 4-pin versions that use a polarization rib (power, tachometer, PWM control): http://www.formfactors.org/developer/specs/REV1_2_Public.pdf
It's everywhere on the web in already-assembled cables but I can't find anything regarding the connector itself using the regular search tools (digikey/mouser/farnell/google)…
The best "reference" I could find is MDY-CO052.

Three-pin Molex connector KK family
This Molex connector is used when connecting a fan to the motherboard or other circuit board. It is a small, thick, rectangular in-line female connector with two polarizing tabs on the outer-most edge of one long side. Pins are square and on a 0.1 inch (2.54 mm) pitch. The three pins are used for ground, +12 V power, and a tachometer signal. The Molex part number of receptacle is 22-01-3037. The Molex part number of the individual crimp contacts is 08-50-0114. The matching PCB header Molex part number is 22-23-2031.
Four-pin Molex connector KK family
This is a special variant of the Molex KK connector with four pins but with the locking/polarisation features of a three-pin connector. The additional pin is used for a pulse-width modulation signal to provide variable speed control.[22] These can be plugged into 3-pin headers, but will lose their fan speed control. The Molex part number of receptacle is 47054-1000. The Molex part number of individual crimp contacts is 08-50-0114. The Molex part number of the header is 47053-1000.
