Datasheet
Balanced Technology Extended (BTX) Boxed Processor Specifications
The TMA receives a Pulse Width Modulation (PWM) signal from the motherboard from the 4th pin
of the connector labeled as CONTROL.
Note:
The boxed processor’s TMA 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 TMA 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 8-7 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.
NOTES:
1. Baseboard should pull this pin up to 5V with a resistor.
2. Open Drain Type, Pulse Width Modulated.
3. Fan will have a pull-up resistor to 4.75 V, maximum 5.25 V
