Note: Diagram does not show the attached hardware for the clip design and is provided only as a mechanical representation.
10.2.2Retention Mechanism and Heatsink Attach Clip Assembly
The thermal solution requires a heatsink attach clip assembly, to secure the processor and fan heatsink in the baseboard socket.
10.3Electrical Requirements
10.3.1Active Tower Heatsink Power Supply
The active tower heatsink requires a +12 V power supply. A fan power cable will be with solution to draw power from a power header on the baseboard. The power cable connector and pinout are shown in Figure
The active tower heatsink outputs a SENSE signal, which is an open- collector output that pulses at a rate of 2 pulses per fan revolution. A baseboard
The fan heatsink receives a PWM signal from the motherboard from the 4th pin of the connector labeled as CONTROL.
The active tower heatsink requires a constant +12 V supplied to pin 2 and does not support variable voltage control or
