We are long past the days when Air Conditioning was considered to be an essential requirement for Computers, but paying a little attention to your computer’s temperature levels can save you some headaches and prevent disasters.
HWMonitor reads all the main health sensors present in your PC. Its a complete solution that displays your voltage levels, fan speeds, CPU temperature, hard disk temperature and graphics card temperature.
I compared the temperature readings provided by HWMonitor with other software available in the market. One thing that caught my attention was the difference between CPU temperatures reported by HWMonitor and Real Temp. This is in all likelihood due to difference in TJMax values assumed by the two softwares. Processor’s don’t directly report their temperatures. Instead the processor’s sensors return a value known as distance to TJMax. TJMax is the temperature at which your CPU would be throttled or your computer you be shutdown. The TJMax values are different for different processors, and Intel no longer supplies the TJMax values for its processors. Thus temperature monitoring utilities are forced to take an educated guess for every model. This is why I would have actually preferred it if my CPU temperature was displayed as a distance to TJMax value. The temperature displayed by HWMonitor agrees with temperature displayed by Coretemp, but based on how hot my laptop actually feel I think that Real Temp is more likely to be correct.
HWMonitor also has a pro version which offers some additional features such as graph generation, system tray icons, fan pwm control and ability to remotely monitor your machines.
All in all HWMonitor from CPUID is another excellent product. It keeps up the CPUID tradition and is a light-weight simplistic software that just works. Although I found it’s selection of TJMax values to be a bit dubious, its biggest strength is its ability to display reports from all the main health sensors.
