MBM5 CpuIdle Plugin
Motherboard Monitor has an option to display the current CPU usage in the windows system tray. However, when CpuIdle or some other software CPU cooler is running, CPU usage is always at 100%, because CpuIdle has its own idle loop that uses up any remaining CPU cycles. This small MBM plugin fixes the displayed value by subtracting the CPU usage caused by CpuIdle from the total usage.
MBM5-CpuIdle is free software released under the GNU GPL.
The latest version of the MBM5 CpuIdle Plugin is mbm5cpuidle-1.1.zip (42k, source included).
