The boxed Intel Celeron processors in the PPGA package at 500 MHz and below are shipped with 
an unattached fan heatsink with two wire power-supply cables. These two wire fans do NOT 
support the motherboard-mounted fan speed monitor feature. The Intel Celeron processor at 
533 MHz and above ship with unattached fan heatsinks that have three power-supply cables. These 
three wire fans DO support the motherboard-mounted fan speed monitor feature. 

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. 

 shows the recommended location of the fan 

power connector relative to the 242-contact slot connector. 

 shows the recommended 

location of the fan power connector relative to the 370-pin socket. For the S.E.P. Package, the 
motherboard power header should be positioned within 4.75 inches (lateral) of the fan power 
connector. The motherboard power header should be positioned within 4.00 inches (lateral) of the 
fan power connector for the PPGA and FC-PGA/FC-PGA2 packages.
