Download ThrottleWatch 0.9

The folks at Panopsys recently released a new version of ThrottleWatch released† The program has arrived at version 0.9 and is from this location as a zip package. In addition to the processor load, ThrottleWatch also shows the so-called throttle of a Pentium 4, Xeon, Pentium M and Celeron processor. The program is able to display two types of throttling. What those are is explained below:

TM1: “Thermal Monitoring 1” throttling is a feature of Pentium 4, P4 Xeon, Celeron (“Northwood” or “Prescott” cores), and Pentium M CPUs. TM1 throttling does not reduce the CPU clock speed – it inserts idle cycles into the instruction pipeline to reduce the processing load on the CPU, which in turn lowers the CPU temperature.

TM2: “Thermal Monitoring 2” throttling is a superset of TM1 and is used on LGA-775 versions of the Pentium 4 and Celeron processors and also on the Pentium M series of processors. TM2 reduces processor temperature by lowering the CPU clock multiplier, and thereby the processor core speed.[break]
