Fan Connections

There are two fan connections, the system fan and the CPU fan. The fan speed can be detected and viewed in the PC Health Status section of the CMOS Setup. Both fans are automatically turned off after the system enters S3, S4 and S5 mode.

Note that the CPU fan cable can be either a 3-pin or a 4-pin connector. Connect a 3-pin connector to pins 1, 2, and 3 on the motherboard connector.

The nForce SPP and MCP have a passive heat sink that draws heat from the chips. You can install a fan onto the SPP heat sink that helps to cool the chips. Hook the fan over the SPP heat sink. Use the two screws to secure the fan to the SPP. Plug the cable into the fan connector.
