Boxed Processor Fan Heatsink Airspace Keepout Requirements (side view) 94 Datasheet Boxed Processor Specifications 8. 4. 2 Variable Speed Fan If the boxed processor fan heatsink 4-pin connector is connected to a 3-pin motherboard header it will operate as follows: The boxed processor fan will operate at different speeds over a short range of internal chassis temperatures. This allows the processor fan to operate at a lower speed and noise level, while internal chassis temperatures are low. If internal chassis temperature increases beyond a lower set point, the fan speed will rise linearly with the internal temperature until the higher set point is reached. [. . . ]
