I use Everest Ultimate Edition 4.6 for this, it puts the temp icons in the systray:

Attachment 184

The icons in order are

  • (WinPatrol),
  • CPU Core (yellow) voltage,
  • CPU Cooling Fan (red),
  • HDD1 & HDD2 temps (black),
  • GPU Diode temp (blue)
  • CPU1 Core1, CPU1 Core2 & CPU temps (maroon)
  • Motherboard temp (green)
  • and finally the Everest icon.

NOTE: this is the default setup, it's configurable (which sensors, C or F, colors, etc) via Options.
