Safety notice
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
devices whilst the system is running. This may damage the Alphacool Heatmaster 2 or even the PC
hardware.
Never interrupt a Firmware update. This may irreparably damage the controller software of the Alphacool
Heatmaster 2, resulting in the controller needing re-programming with a special programming device.
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

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)
Laing DDC-1T Plus (RT-Models) (Active Air cooling needed)
Laing D4/ Laing D5 (Active cooling needed)
Alphacool TPP644 / VPP655 ((Active cooling needed)
Phobya DC12-220/260/400
Please note that the Alphacool pump adaptor may be needed for some models!
Flow rate sensors
Bach DFS 1/25io
Some Digmesa DF sensors
GMR DF Sensor including electronics
Innovatek FlowMeter

ALWAYS ensure correct connection to the pins! If incorrect connections are made or pins are
shorted out, damage may be caused to the Alphacool Heatmaster and / or the connected hardware.
Pay special attention to the correct connection of the USB cable. If the cable is connected improperly
damage may be caused to the Alphacool Heatmaster 2 or the connected hardware. Never remove the
USB connection cable when the system is switched on. The Heatmaster 2 is not hot-plug capable.
HM BUS
Heatmaster 2 BUS-utilization inquiry.
Emergency shutdown
Output for switching of a relay. Via this feature the hardware can be switched off immediately in case of an
emergency. The switching current must not exceed 100mA. Data corruption cannot be ruled out if the
emergency shutdown is activated.
PC shut down
This output can be connected to the Mainboard. When the shut-down signal is sent, the output works like the
power switch of the system.
NTC 1 -6 temperature sensors
Here the temperature sensors can be connected. Use only sensors with a resistance of 5k Ohm or 10k Oh.
The Heatmaster 2 detects these after a reset. The setting can also be made manually.
Water level
To this input an analogue coolant level sensor can be connected. With this sensor the Heatmaster is able to
give a warning if the coolant level is too low.
LED 1 silent alarm
Status LED. This connector is active when the silent alarm is activated. The switching current must not
exceed 2mA.
LED 2 alarm
Status LED. Is active when the alarm is activated. The switching current must not exceed 2mA.
LED 3 warning
Status LED. Is active when a warning is activated. The switching current must not exceed 2mA.
Relay 1-3
With the outputs relays can be controlled, the switching current must not exceed 80mA.
Button 1-3
Inputs for 3 buttons. The buttons must be equipped with a make contact to allow the Heatmaster 2 to
interpret the signal correctly.
Heatmaster reset
With the Jumper the Heatmaster can be restarted. To restart remove the jumper for a short period of time
and plug it in again.
When conducting a hardware reset it is necessary to disconnect the Heatmaster 2 in the software if
the software is started.
IMPORTANT: A reset switches off all outputs!
5V Standby
Power supply for stand-by operation. The PSU must be able to supply at least 1A of current at 5V.
12V and 5V output
Power supply for external devices.
