Balanced Technology Extended (BTX) Type I Boxed Processor Specifications
Note: The boxed processor’s fan heatsink requires a constant +12 V supplied to pin 2 and does not
support variable voltage control or 3-pin PWM control.
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 platform
documentation, or on the system board itself. Figure 8-5 shows the location of the fan power
connector relative to the processor socket. The baseboard power header should be positioned
within 4.33 inches from the center of the processor socket.
