2 Pack 4-Pin Molex (Actual 2-Pin) to 2 x 3 Pin / 4 Pin PMW 12V PC Case Fan Power Adapter Cable, PC Fan (PWM Connector) to Molex Computer Cooler Cooling Fan Splitter Y Power Cable
Bottom line: The 2 Pack 4-Pin Molex: Powers two 3-pin or 4-pin case fans per cable from a single Molex plug; main trade-off: fans run at fixed 12V, so no PWM speed control.
