All changes you make here are applied to the MBM 5 sensor you selected

High temperature alarm using

Here you have 2 options, Fixed or Relative. Fixed is the default option and should be use 95% of the time. It simply means thaty ou set a fixed value at which an alarm should be raised.

Relative means the alarm value is relative to the readings of another sensor + a value you set. The reason for this feature is best explained in the next part, send in by the MBM user who requested this feature:

Functionality?
Set the high temperature alarm for one sensor relative to another.

Why do I want to use this function?
For instant you are an extreme overclocker and you decided that peltier and water-cooling is the ultimate path to take. At this point in time the CPU high temperature become very importance, one mishap with the water pump could instantly fry your CPU. Therefore the high temperature alarm should be very sensitive, however CPU temp depend on two criteria: CPU heat dispensation, and ambient heat (case). Hence we cannot specify an accurate CPU high temperature alarm, since the ambient temperature is vary from time to time. This where this function comes in, it allows you to set the CPU high temperature relative to ambient (case) temperature if you know the max temperature output of your CPU.

How do I determine my CPU max temperature?
Start up CPU warming software (ie. Prime95, CPU stability or CPU burn ect.)
for an hour or so, records the CPU temperature and the Motherboard temperature.

The max CPU temperature = recorded CPU temperature – recorded Motherboard temperature

Example:
The max CPU temperature = 21 + 3(margin of error)
Sensor 1: CPU Temperature
Sensor 2: Motherboard Temperature

Under Sensor 1 Alarm Settings

Selects “Relative Value”
High temperature alarm equals value of Sensor: Sensor2 + 24

If the Motherboard Temperature is 20
Then the CPU High temperature alarm become 44

If the Motherboard Temperature change from 20 to 30
Then the CPU High temperature alarm become 54

High temperature alarm at (if Fixed is selected above)

Select at which value a High (too hot) alarm should be raised, .

High temperature equals value of alarm of the sensor (if Relative is selected above)

How this works is explained above, simply select another sensor and add your max CPU temp value. It is not possible to select the same sensor as your working on, to avoid a loop.

Enable high temperature alarm for this sensor

Check this box to enable the High (too hot) alarm

Low temperature alarm at

Select at which value a Low(too cold) alarm should be raised

Enable low temperature alarm for this sensor

Check this box to enable the Low (too cold) alarm

Compensation for this sensor

Some sensor might need a compensation value added to subtract from the value the sensor chip reports. Here you can select how much

When alarm goes off, play sound

If an alarm goes off you can select a wav that should be played. This option only works if you select to show the alarm dialog box in the Alarm section

When alarm goes off, start application

If an alarm goes off you can select a program that needs to be executed.

Start application with the following switch

The application you selected might need to have a so-called switch sent to it; enter the switch in this box

When alarm goes off, start SHDN

If an alarm goes off you can make MBM 5 start SHDN now, if it is installed !This option only works if you select to show the alarm dialog box in the Alarm section

Start SHDN now with the following switch

SHDN now has several switches you can start it with. In this listbox you can see them all; you can also enter your own switch if needed

SHDN delay

This determines how long MBM 5 will warn you before SHDN is executed

Send E-mail when alarm goes off

If you check this option AND you filled in the e-mail section correctly, MBM 5 will send an e-mail when an alarm goes off
