There has not been any code change since December 2020, also the community now wonders if it is abandoned: https://github.com/openhardwaremonitor/openhardwaremonitor/issues/1471 There also seems to be a fork called LibreHardwareMonitor (which is already listed as an alternative) and appears to be the most active fork right now.

This is what I install on a new computer. Strong preference towards free and open source software. Hand picked.
What is Open Hardware Monitor?
The Open Hardware Monitor is a free open source software that monitors temperature sensors, fan speeds, voltages, load and clock speeds of a computer.
The Open Hardware Monitor supports most hardware monitoring chips found on today's mainboards. The CPU temperature can be monitored by reading the core temperature sensors of Intel and AMD processors. The sensors of AMD and Nvidia video cards as well as SMART hard drive temperature can be displayed. The monitored values can be displayed in the main window, in a customizable desktop gadget, or in the system tray. The free Open Hardware Monitor software runs on 32-bit and 64-bit Microsoft Windows XP / Vista / 7 / 8 / 8.1 / 10 and any x86 based Linux operating systems without installation.






Comments and Reviews
Why I like Open Hardware Monitor: This is one of the only apps I can find, other than SpeedFan and MSI Afterburner, that reads my GPU and CPU temperatures AND can put the values in the System Tray.
I can also put fan speeds, clock speeds, and any of many other values it reads in the Sys Tray. SpeedFan works, but crashes a lot for me. MSI Afterburner works too, albeit through a far more complex interface, and the (bitmapped/blocky/unscalable) tray font is hard to read. Open Hardware Monitor is small, straightforward, has an easy to read (and antialiased/scalable) tray font, and is easier to configure for novices. 5 stars.

It's a descent app, as soon as you own old hardware, because it's updated every 2 years (last update Nov 2016). If you have new hardware, it's very possible to have wrong values for sensors, like I have (-25 Celsius for my motherboard's temperature!)
hey, this app was last updated in December 2020, and yep, there was a big gap between Nov 2016 - Feb 2020
Missing most data - use Libre Hardware Monitor instead.
Pro: Can display desired data in systray icons. Con: Requires admin privileges to read CPU temperature
I liked that it was free, concise and fast
For me, THE BEST, simple open-source app for monitoring my hardware temperature and resources. Straight to the point. Has got a widget. No installation required. Small footprint.
straightforward and simple to use
