Heatmaster 2

Speed factor
This factor represents how many signals per revolution are sent by the fan. Normal PC fans have a value of
2 impulses per revolution. In rare cases or with unusual fans this value may also be higher or lower. Some
fans have reduced signal quality at low speeds, hence not allowing a speed signal to be registered. Is the fan
is operat
ed outside of the “clean signal range” it is also possible to set the voltage as the control unit instead
of the rpm signal. If the voltage is set as control unit the Heatmaster is unable to monitor the functionality of
the fan.
Manual temperature control
Voltage and fan speed can be set manually by setting the target value on the sliding bar
.
Automatic temperature control
One or even two sensors can be assigned to each fan, allowing automatic speed control of the fan
depending on the temperature. If two sensors are assigned, the one with the higher monitored temperature
will automatically be used for determination of the
fan’s target speed. Now the following options can be used:
Linear: A linear speed curve between starting temperature and maximum temperature will be used
for determination of the fan target speed.
Progressive: The control curve begins with a flat slope and becomes steeper the closer the
monitored temperature is to the maximum.
Target value: The fan will start to spin below the set target temperature and the automatic fan speed
control will try to hold the target temperature as constantly as possible. Due to many factors coming
into account when trying to maintain a certain temperature, such as heat dissipation, pump
performance, room temperature etc. or contradicting control factors, it is not always possible for the
Alphacool Heatmaster 2 to maintain the set target temperature. This is not an error or reason for
reclamation, but rather caused by the many possible settings of the Heatmaster 2 as well as the
complexity of a water cooling system.
Switch-off hysteresis: Temperature difference value which prevents pointless start-up and switch-off
of the fan near the starting temperature. The more directly the system reacts, the higher this value
should be set. Alternatively the starting speed of the fan can be decreased. In systems with slow
temperature changes, e.g. due to high thermal capacity, a low hysteresis value is of advantage.
Temperature sensors configuration
Here the sensor channel for which the settings will be made can
be chosen
IMPORTANT: Only set the status to ON if a sensor is actually
connected. Otherwise false values will be displayed.
Name:
It is possible to set a name for every sensor channel individually.
The name may contain up to 255 characters made up of letters
and numbers.
Status
Sets the status of the sensor to: Off, not connected or On.
Emergency shutdown
If this feature is set to ON, the system will initiate an emergency
shutdown of your PC system if set temperature is reached
Settings
Here sensor-specific settings can be made. The Heatmaster
software has two NTC tables which are set for the currently sold
5kOhm respectively 10kOhm temperature sensors. With the
correction value
“rough” measuring errors can be significantly
reduced. Should the included NTC table cause major deviations, it is possible to save another NTC table
which can be used. This feature is also very useful when completely different sensors are being used. Hence
the Heatmaster 2 is compatible with virtually all currently available and future resistance-based temperature
sensors. The Heatmaster 2 allows only one NTC table to be used at a time, which will be used for all
connected sensors.
