How to log CPU temperature
Keep track of your CPU's temperature using free software. (cpu image by Aussiebloke from

Dusty CPU (Central Processing Unit) fans and poorly ventilated cases, among other things, can cause the heat of your computer's CPU to rise to damaging temperatures, which can make your computer crash or burn out the CPU. But with the help of a CPU temperature monitoring utility, you can keep a log of your CPU's temperature and work out a course of action for lowering it if it gets too high.

Skill level:
Moderately Easy


  1. 1

    Log your CPU's temperature using a free copy of eFMer BOINC's TThrottle utility (see Resources). TThtrottle allows you to monitor your CPU and multiple CPU cores. You can set a temperature limit, and TThrottle will adjust your CPU's workload to decrease the temperature. The program's "Logging" option allows you to send a log report directly to an e-mail account, whether it be your account or a network administrator's account.

  2. 2

    Generate a log of your CPU's temperature with the help of Real Temp (see Resources). Designed for Intel processors, Real Temp allows you to get temperature data on up to four CPU cores. CPU temperature log files can be set at user-defined intervals and can be exported from the program in CSV (Comma Separated Value) format. However, Real Temp's glaring drawback is the utility's inability to support AMD processors.

  3. 3

    Download a free copy of SpeedFan to monitor your CPU's temperature (see Resources). SpeedFan monitors the fan speed, voltages and temperatures of a computer's internal components. With SpeedFan, you can log real-time temperature data on your CPU and adjust the CPU fan's speed accordingly. To generate a log, click on the utility's "Configure" button, select the "Log" tab and then check the "Enabled" box.
