Temperature Monitoring

BurnInTest V7 and later supports temperature monitoring directly and also via many third party system monitoring applications currently available. By using BurnInTest or BurnInTest with these applications, is it possible to Burn in your hardware while monitoring, graphing and logging the temperature of your CPUs, GPU and Hard Disks.

About BurnInTest temperature monitoring
BurnInTest provides 3 types of temperature sources:

1) AMD and Intel CPUs (temperature average of CPU cores or a specific core);
2) Newer AMD and nVIDIA Graphics cards;
3) Hard Disks that support S.M.A.R.T.

Most modern CPUs include a thermal monitoring capability for fan speed threshold triggering and CPU protection purposes. These are not highly accurate temperature sensors. CPU temperatures can generally be sourced directly from the CPU or from an external component on the Motherboard (e.g. a SuperIO chip). In all cases, the CPU temperature reported by BurnInTest is sourced directly from the CPU and this may vary from externally reported CPU temperatures. These values should be treated as approximate values. In general the CPU temperature is more accurate at higher temperatures (as this is when the CPU mainly utilizes the temperature monitoring), and less accurate at lower temperatures. Some Intel CPU temperatures less than 50C may mean little more than just that, the temperature is less than 50C. While the temperatures may have a high degree of error at lower temperatures, the values can still be quite useful in determining differences between temperatures, such as determining whether a different cooling solution leads to a higher or lower CPU temperature.

The CPU temperature calculation is specific to each type of CPU. The current version of BurnInTest supports most Intel and AMD CPUs launched since 2011.

The GPU temperatures are sourced from the AMD or nVIDIA graphics cards via their device driver. As such the graphics cards and the device drivers must support temperature monitoring.

The Hard disk drive (HDD) temperatures are sourced from the disk S.M.A.R.T. attributes. As such the disk needs to support S.M.A.R.T. - most modern HDD's do.

About Intel Active Monitor

About Hmonitor
Versions tested with BurnInTest: 4.0, 4.5 and 5.5
Hmonitor Pro monitors and displays hardware parameters collected by the several sensor chips, installed on certain motherboards. The program can monitor voltages, CPU temperature, Motherboard temperature and cooler fans RPMs. It is fully customizable with alarms that can be set to go off when the temperature goes too high. In addition to this there is a built in "thermo control" function, that kicks in when the CPU is idle. Hmonitor can be used under Windows 98 or 2000/XP/Vista operating systems on Intel-based personal computers.
Hmonitor is currently available at

About MBM (Motherboard Monitor)
Versions tested with BurnInTest: 5.3 and 5.5
MBM monitors CPU temperatures, motherboard temperatures, voltages and fan speeds. It contains some basic system information and supports programmable alerts (also email alerts or application launch on alert), and logging. However several years ago, Alexander Van Kaam the developer of MBM, announced that development on Motherboard Monitor has been stopped due to lack of financial resources to purchase hardware and the difficult in getting technical details from the motherboard manufacturers. The web site has also now be closed. Copies of the software are still available on the Net however if you search for them.

About SpeedFan
Versions tested with BurnInTest: 4.08, 4.32, 4.35, 4.37, 4.49
SpeedFan monitors CPU temperatures, motherboard temperatures, voltages and fan speeds. It allows the user to alter fan speeds to aid the overclocking enthusiast. It reports system information - in particular SM Bus info and SMART attributes.

General comments about using the 3rd party applications
In the case of each 3rd party temperature monitoring application…

BurnInTest reads the CPU temperature values from the third party monitoring application, displaying them on the screen and writing them to disk if logging is turned on. Please bear in mind that the accuracy of the temperature values in BurnInTest depend entirely on the third party application in question.
