Installing a Processor Fan Heat Sink

The LGA2011 processor socket has four threaded holes for mounting a processor fan heat sink. Figure 14 shows installation of a typical processor fan heat sink; yours may differ. For detailed instructions on attaching a processor fan heat sink to the Desktop Board, refer to the Intel boxed processor manual, Intel boxed thermal solution manual, or instructions third-party thermal solution providers.

Connect the processor fan heat sink cable to the 4-pin processor fan header (see Figure 14). A fan with a 4-pin connector as shown in Figure 14 is recommended; however, fans with a 3-pin connectors can be used. However, since a 3-wire fan cannot use the onboard fan control, the fan will always operate at full speed.
