Standard PC fans expect a PWM frequency of roughly 25kHz (21kHz to 28kHz).
If you want to run the fan at 100% speed without a motherboard (e.g., using a bench power supply or a generic 12V adapter):
The Foxconn PVA092G12H Go to product viewer dialog for this item.
is a standard 4-pin DC brushless cooling fan (92mm x 25mm) commonly used in Dell and HP systems. It operates on 12V DC at 0.40A and features Pulse Width Modulation (PWM) for precise speed control ranging from 900 to 3600 RPM. Standard 4-Wire Pinout & Color Coding While wire colors can vary, the PVA092G12H
typically follows the industry-standard 4-pin motherboard header configuration: Pin Number Typical Color Description Pin 1 Black Ground (GND) 0V reference. Pin 2 Yellow +12V DC Constant power supply. Pin 3 Green Sense (Tach) RPM feedback signal to the motherboard. Pin 4 Blue Control (PWM) Speed control signal from the system. [SOLVED] - Notches on 4-pin fan don't match - need adapter

Users searching for this specific model often have issues. Here is how to fix the top three.
If you want to manually control the speed without a motherboard: If you want to run the fan at
You cannot use a simple rheostat (variable resistor) on the power line for brushless fans; this will cause the motor to stall or overheat. You must control the PWM pin.
