4.5.4 Thermal Sensing and Cooling

All systems feature a variable-speed fan mounted as part of the processor heatsink assembly. All systems also provide or support an auxiliary chassis fan. All fans are controlled through temperature sensing logic on the system board and/or in the power supply. There are some electrical differences between form factors and between some models, although the overall functionality is the same. Typical cooling conditions include the following:

1.Normal—Low fan speed.

2.Hot processor—ASIC directs Speed Control logic to increase speed of fan(s).

3.Hot power supply—Power supply increases speed of fan(s).

4.Sleep state—Fan(s) turned off. Hot processor or power supply will result in starting fan(s).

The RPM (speed) of all fans is the result of the temperature of the CPU as sensed by speed control circuitry. The fans are controlled to run at the slowest (quietest) speed that will maintain proper cooling.

Units using chassis and CPU fans must have both fans connected to their corresponding headers to ensure proper cooling of the system.
