Open Hardware Monitor is an open source application to monitor your computer`s temperature sensors, fan speeds, voltages as well as CPU load and clock speeds. The program runs as standalone executable and does not require installation. It automatically generates an overview of all available sensors and their real-time values and also allows you to add selected sensors as icons to your system tray, so you can keep an eye on them without keeping the main interface open. Other features include plotting of temperature graphs, support for S.M.A.R.T. sensors, export to text report and remote monitoring via browser interface.
