Thermal Monitor 2
Appearance
TM2, or Thermal Monitoring 2, is a throttling control method used on LGA 775 versions of the Pentium 4, Pentium D and Celeron processors and also on the Pentium M series of processors.[1] TM2 reduces processor temperature by lowering the CPU clock multiplier, and thereby the processor core speed.[2] In contrast, TM1 inserts an idle cycle into the CPU for thermal control without decreasing multipliers.
