Processor Thermal Features
6.3.1
Thermal Monitor Features
Quad-Core Intel® Xeon® Processor 5300 Series provide two thermal monitor features, 
Thermal Monitor (TM1) and Enhanced Thermal Monitor (TM2). The TM1 and TM2 must 
both be enabled in BIOS for the processor to be operating within specifications. When 
both are enabled, TM2 will be activated first and TM1 will be added if TM2 is not 
effective.
6.3.2
Thermal Monitor (TM1)
The Thermal Monitor (TM1) feature helps control the processor temperature by 
activating the Thermal Control Circuit (TCC) when the processor silicon reaches its 
maximum operating temperature. The TCC reduces processor power consumption as 
needed by modulating (starting and stopping) the internal processor core clocks. The 
temperature at which Thermal Monitor activates the thermal control circuit is not user
