ThrottleWatch™ is a utility for detecting and reporting the CPU throttling activity in Pentium 4, Xeon, and Pentium M processors.

The amount of heat a CPU produces varies according to the processing load. In situations of high sustained load (such as performance benchmarks, etc...), a CPU may produce more heat than the cooling mechanism is capable of removing, and reach a high enough internal temperature to trigger throttling.

ThrottleWatch™ monitors and graphically displays both the CPU load and any throttling that occurs.

When ThrottleWatch™ is minimized, an icon is added to the system tray area of the Taskbar. The color of the icon changes when throttling is detected.
