CPULed is a handy tool that helps you monitor the activity of your CPU. It uses a color code that depicts its load (light, medium or hard) so that you can instantly get the information that you are looking for. This light-weight application resides in the menu bar so it will never get in your way and affect your workflow.

CPULed is able to display the overall information about your average CPU activity or to show separate windows for each of your cores. Furthermore, it offers you a quick way to access the system activity monitor so that you can see how many resources are allocated for each of your running applications.

The options that CPULed provides will allow you to determine the refresh time interval, to choose the icons set that you want to use, to select the temperature scale that you desire (Fahrenheit or Celsius), to add extra space between the icons of the program or to quickly purchase some handy add-ons.

To sum it all up, CPULed is a great tool to have at your disposal when you need to keep an eye on the activity of your CPU. This program will help you constantly supervise your processor while also giving you all the information that you require.
