Chassis and cpu fans may use either 3 pin or 4 pin power connectors.
Connect 3 pin chassis fan to 4 pin motherboard.
The image below displaying is the difference between a 4 pin pwm fan connector left and a 3 pin fan connector right installing a 3 pin fan to the motherboard.
4 pin connectors areusually used by cpu fans with higher power consumption.
A four pin connector is a little different than the three pin connector since it has the extra fourth wire used for controlling and sending signals to the fan which likely has a chip on it that tells it to slow down or speed up in addition to the other wires the three pin connector has.
