About Libre Hardware Monitor

Libre Hardware Monitor reads sensors from motherboards, Intel and AMD processors, NVIDIA, AMD and Intel graphics cards, hard drives and network cards, and shows temperatures, fan speeds, voltages, load and clock speeds in one tree.

It is a fork of the abandoned Open Hardware Monitor, kept alive with support for current hardware. It also ships as a library other programs use, which is why it turns up as the sensor backend inside Rainmeter skins, fan control utilities and stream overlays.

Strengths

  • Reads motherboard, CPU, GPU, drive and network card sensors
  • Also a library, so other tools can use it as their sensor backend
  • Portable ZIP, with nothing to install
  • Actively maintained where Open Hardware Monitor was not

Limitations

  • Windows only
  • Needs administrator rights to read low-level sensors
  • Readings can be wrong on unusual motherboards until someone fixes it
  • Interface is a plain Windows Forms tree
