Pentium III Processor for the PGA370 Socket up to 750 MHz
6.1.4
Heatsink Grounding for the Boxed Processor
Intel recommends that customers implement EMI heatsink ground pads on any platform under
development that will support Pentium III processors in the PGA370 socket. This recommendation
provides the ability to utilize Heatsink Grounding should it become necessary to pass EMI
emission regulations. Depending upon the platform emission characteristics, platform/processor
compatibility, platform lifetime, etc., Heatsink Grounding may not be required and, therefore,
OEMs should make the decision to implement the ground pads based upon their specific platform
design characteristics and needs. Intel will enable an EMI Heat Sink Grounding Clip solution based
upon the recommended EMI Ground pad location depicted in Figure 25.

Boxed Processor Requirements
6.2.1
Fan Heatsink Power Supply
The boxed processor's fan heatsink requires a +12 V power supply. A fan power cable is attached
to the fan and will draw power from a power header on the motherboard. The power cable
connector and pinout are shown in Figure 26. Motherboards must provide a matched power header
to support the boxed processor. Table 32 contains specifications for the input and output signals at
the fan heatsink connector. The cable length is 7.0 inches (±0.25"). The fan heatsink outputs a
SENSE signal, which is an open-collector output, that pulses at a rate of two pulses per fan
revolution. A motherboard pull-up resistor provides VOH to match the motherboard-mounted fan
speed monitor requirements, if applicable. Use of the SENSE signal is optional. If the SENSE
signal is not used, pin 3 of the connector should be tied to GND.
The power header on the baseboard must be positioned to allow the fan heatsink power cable to
reach it. The power header identification and location should be documented in the motherboard
documentation or on the motherboard. Figure 27 shows the recommended location of the fan
power connector relative to the PGA370 socket. The motherboard power header should be
positioned within 4.00 inches from the center of the PGA370 socket.
