Temperatures Based on Fan Speed

Mother Board Monitor 5 now supports RPM conversion for temperature sensing variable speed fans or "smart" fans. Smart fans increase their speed and airflow in response to a temperature sensor mounted on the fan. MBM 5 cannot read the fan's temperature sensor directly but it can provide an estimate based on the fan's speed and a user supplied calibration table.

Important: MBM 5 does NOT control the fan speed -- it just estimates the temperature that the fan's sensor is reporting.

Configuring This Advanced Feature

1. Close MBM 5 if it is already running.
2. Locate the MBM 5.ini file and open it with a text editor.
3. Locate the line "Temp Based on Fan Speed=0" in the [Advanced] section and change it to "Temp Based on Fan Speed=1"
4. Edit the FanTempList.ini file to describe the relationship between RPM and temperature for your fan. (See sample
   calibration tables below.)
5. As of MBM 5.3.5.0 you need to rename the Fantemplist.ini to FanTempListX.ini where X is the fan number you want it based on, this way you can have a FanTempList per fan sensor
6. Start MBM and open the Settings screen. The Temperatures sensor pulldown list will now include "Based on Fan 1 speed, Based on Fan 2 speed,...Based on Fan 16 speed."
7. Select the variable speed fan you wish to use for temperature estimates.
8. 7. You should now have a temperature reading based on the selected fan's speed and your calibration table.

Remember, the reading you get is only as accurate as your calibration table and MBM 5 is NOT controlling the speed of your fan.

Sample Calibration Table for 80mm Thermal Take Smart Case Fan. Each fan should be individually calibrated for the most accurate results. (This fan has its temperature sensor on a 3" lead making it possible to position it for several configurations. Its temperature response range runs from about 25 to 35 degrees C. Available from http://www.thecardcooler.com/ )

Sample Calibration Table for 92mm Generic Variable Speed Fan. Each fan should be individually calibrated for the most accurate results. (This fan has its temperature sensor mounted directly on the hub making it best suited as an exhaust fan. Its temperature response range runs from about 15 to 45 degrees C. Available from http://www.thecardcooler.com/ )
