Please thoroughly read this safety notice to prevent possible errors which may lead to problems or damage
to your hardware.
Not suitable for children under 12 years (contains swallowable small components). Some components on the
Alphacool Heatmaster 2 may become very hot. Please be aware of the danger of burning and be extremely
cautious when touching the device.
Read this operating manual thoroughly before installation.
Before beginning working on your system please back up your data.
The Alphacool Heatmaster 2 must be installed solidly in a free space in the enclosure.
Please make sure that the USB connector is connected with the correct polarity. If the USB cable is
connected with wrong polarity, both the Mainboard as well as the Alphacool Heatmaster 2 can be damaged.
Never plug the power connector in or out whilst the PC is switched on. This can destroy the hardware of your
PC (PSU, USB connector, mainboard etc.) or even the Alphacool Heatmaster 2.
Never connect or disconnect fans, flow rate sensors, temperature sensors, relays, LEDs or other sensors or

Never interrupt the software start-up of the PC software.
Do not shut down your PC suddenly by e.g. cutting the power or switching off the PSU whilst the system is
running.
Never touch the Alphacool Heatmaster 2 or one of the connected devices whilst switched on.
Intended use
The Alphacool International Gmbh cooling components are approved by Alphacool International Gmbh for
cooling of computer components. If they are used for any other purpose the warranty is voided.
System requirements
Minimum system requirements:
CPU: 500Mhz or better, recommended 1000Mhz
RAM 512 MB
50 - 100 MB HDD space
USB 1.1
Windows XP Service Pack 3, Windows Vista, Windows 7.

Heatmaster 2
7
Windows 98 SE, Windows 2000 Service Pack 4 with limitations.
Depending on the operation being processed the software requires some of the CPU computing power. If
you have transferred the settings to the Alphacool Heatmaster 2 and the software has been shut down, no
more CPU time is needed. The Alphacool Heatmaster 2 then runs autonomously and fulfills its purpose of
controlling and monitoring your cooling system. The Alphacool Heatmaster 2 is even network- and internet
capable with the optionally available LAN adaptor. This allows the Alphacool Heatmaster to be configured
from another PC, meaning that no software needs to be installed on the monitored system, hence not
requiring any CPU time on the system.
More information on possible expansions can be found at the manufacturer homepage www.Alphacool.com
Socket assignment
Overview
Power supply
The Alphacool Heatmaster 2 is connected to the power supply via a 4-Pin Molex plug, just like a HDD or
optical drive. Both voltage (12V and 5V) are needed, the 5V for the micro controller and 12V for the power
connectors, supplying fans and pumps. Should you intend to connect the Alphacool Heatmaster 2 to another
power source than a PC PSU (e.g. in an external enclosure or via a laboratory power supply), please note
that not only a 12V rail is needed, the 5V power rail is also required. If you intend to run the unit in stand-by
(e.g. to allow booting of the system to be triggered by the Alphacool Heatmaster 2), a 5V standby power
supply must be connected via the connection array (see overview).
Fan channels / pumps / slow sensors
Up to 6 fans can be connected to and individually controlled by the Alphacool Heatmaster 2. Additionally it is
possible to connect multiple fans to one channel via a Y-cable or similar adaptor. In such a configuration the

Heatmaster 2
8
fan speed signal from only one fan can be monitored, but the other fans run at the same voltage. Such a
configuration is especially useful if many fans need to be connected to a cooling array. For example, three
radiator fans can be connected to one channel. Bundling of radiator fans also comes in very handy if large
radiators such as the Mora or Phobya Nova (9 fans each). The maximum permissible number of connected
fans depends on the power consumption of the fans. Up to 18W of power may be drawn from an individual
channel passiv cooled..We propose to use an aktiv fan. The power consumption of a standard 120mm fan is
approximately 2.5 to 3.6W. Before connecting multiple fans please check the maximum power draw of the
fans. Should the 10W per channel not suffice, an active cooling system of the driver components can
increase the maximum power output up to 38W. Regarding this please consult the appendix.
The last three channels (3-Pin) are unregulated for the pumps / flow sensors, as these are controlled
separately by the software. Theoretically it is also possible to connect a fan, but the channels are unable to
detect it as such, resulting in constant 12V operation of the connected fan. The 3 channels for pumps / flow
sensors aren’t necessarily compatible with the according components. This means that in some cases it is
e.g. necessary to connect a 3-Pin plug to the pump / flow sensor. Please check in advance if the pump is
suitable for the limitations of the Alphacool Heatmaster 2 (18W per channel). On the 3 channels the 12V DC
voltage from the PSU is simply passed through, hence additional voltage adjustments are not possible. If you
wish to control the speed of your pump, this is possible with an analogue adaptor which is connected parallel
to the 6 fan channels. This allows a pump to be connected and controlled in speed e.g. according to a
measured temperature. Such analogue adaptors will be available soon. The following products can be
connected to the pump / flow sensor channels:
Pumps
EK-DCP 2,2 /4,0
Laing DDC-1T / Laing DDC-1T Plus ( requires active cooling) (as well as the RT models)

hardare to allow the Mainboard to recognize this as a switching contact. Normally the pre-set 8 seconds
should be plenty. The setting should only be changes if there are problems with the Mainboard.
Display configuration
Important note in advance:
To use this feature a display must be connected to the data
cable. The display must also allow brightness adjustments.
Multiple displays will be able soon, for more information go to
www.Alphacool.com
Brightness during operation:
Here the brightness of the display lighting during operation can
be set.
Brightness in sleep mode
Here the display brightness in sleep mode can be set
(recommended setting: 0%)
Brightness of stand-by lighting
If no activity is detected, the display can be switched to stand-
by mode. We recommend reducing the brightness ion stand-by
mode.
Standby time
Here the period of time of inactivity after which the display will
go into stand-by mode can be set.
Fan configuration
Here the fan channel for which the settings will be made can be
Name
It is possible to name every fan channel individually. The name
may contain up to 255 characters made up of letters and
numbers.
Status
Sets the mode of the fan between: Inactive, not connected and
active
Speed monitoring
Here it can be set if the fan is equipped with a speed monitoring
feature. This is usually only the case i fit is equipped with a rpm
lead.
Fan switch-off in case of failure
If the fan is controlled by the Heatmaster to a target speed or
voltage, but does not send a signal back, this feature will prevent
the Heatmaster from trying to spin up the fan until the next
system start-up.
Action in case of fan failure
here different alarm levels can be set. If the fan is a system-
critical fan it is often useful to set an alarm or even system shut-down here.
Determine Min. / Max. speed
We recommend determining the minimum and maximum speed once per each fan to allow the Heatmaster 2
to determine the relevant data. If fluctuating values for maximum and minimum speed are to be expected, a
check after every start-up can also be set.

Heatmaster 2
18
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 operated 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.

Heatmaster 2
19
Temperature values
The values for “warning”, “alarm” and “emergency shutdown” can only be set with ascending temperature
values in this order. Hence it is not possible to monitor the system for undercutting of a certain bottom
temperature with this feature. Setting of an alarm or setting when undercutting a certain temperature is
possible with the “Online button / relay” feature though.
Pump / flow rate sensor configuration
Here the pump / flow rate sensor channel for which the settings are going to be made can be chosen.
Name
It is possible to set a name for every channel individually. The
name may contain up to 255 characters made up of letters and
numbers.
Status
Sets the status of the channel to: Off, not connected or On.
Type
Here the channel can be set to pump or flow rate sensor mode
Factor
This factor represents how many signals the pump / flow rate
sensor sends per revolution. Normal flow rate sensors have a
value of two. In rare cases or with different components this
factor may also be lower or higher. For pumps this value must
be determined by the user.
Pump settings
If a pump is connected, it can be monitored. Should the speed
of the pump undercut a certain value an “action in case of pump
failure” can be set. The choices are: No warning, alarm or
emergency shutdown
Flow rate sensor settings
If the conversion factor “Signals per liter” for the sensor is known, the unit can be set to “liters per hour” or
“Gallons per hour”. Similar to the temperature monitoring it is possible to set an action if a certain value is
undercut. Different values for warning, alarm an emergency shutdown can be set.
