I like to use a simple Windows 7 gadget on the desktop to keep an eye on CPU and RAM usage. The one I use is All CPU Meter
. It will display the temperature for each core if you install PC Meter along with it. The widget is nice to have running in the background.
For stress testing I like to use dedicated software like HWMonitor
, Real Temp
, or Core Temp
since they keep track of Min/Max while the desktop gadget does not.
