Most motherboards will have at least 2 (3pin) fan connectors on them for fans. One marked CPU and the other marked System (some boards have more than 1 system fan connector). The system fan is for air flow through the case. The CPU fan is for the fan on the CPU.

Make sure your radiator fan is connected to the CPU fan connector and the case fans are connected to the SYS fan connectors. Also the fans must have the 3rd RPM wire on it or the motherboard and all software will not be able to control the fan. If your fan only has 2 wires you will not be able to control them through the mobo or software.
