Libre Hardware Monitor is a fork of Open Hardware Monitor. The program's project appears to have started when the development of Open Hardware Monitor seemed to have stalled. The latter has received a few updates recently, after a gap of nearly 4 years. If you haven't used either program, these are real-time system monitoring applications that you can use to observe/log the system's CPU load, Bus Speed, temperature levels. It can be a useful utility to have when you're running intensive games, virtual machines editing videos,, etc., and want to see if the computer could be overheating.
