Or, by lowering the CPU speed first, then if necessary, turning on the fan. Use the Cooling Method item of the Basic Setup window in Power Option. When the CPU temperature falls to a normal range, the fan is turned off and the CPU operation returns to standard speed. If the CPU temperature reaches an unacceptably high level with either setting, the system automatically shuts down to prevent damage. Data in memory will be lost. User's Manual 4-29
