any circumstances. Do not attempt to power the AC4G-D from any source other
than a grounded electric outlet protected by a fuse or circuit breaker.
Not for use in life-support systems.
Package contents
This User’s Manual
AC4G-D drive bay unit, with USB port and cable
AC4G-D cooling unit (for either AMD or Intel)
2 heat sink clips (Intel cooling unit only)
Silicone compound (small sachet)
4 small screws for attaching bay unit (not shown)
______________________________ Installation
A. Preparation
1. Shut down the computer, and disconnect it from the mains electricity
2. Leave the computer to cool down, and then remove the existing CPU
heat sink.
Warning: If the computer has been in use the CPU area may be
very hot. Do not touch any parts until you are sure they have cooled
B. Cooling unit installation
1. Apply a very thin layer of silicone compound (from the small sachet)
to the surface of the CPU.
2. Position the AC4G-D cooling unit on the CPU so that the cold plate
sits squarely over the CPU.
Warning for AMD: The cooling unit for AMD has a small step in the base.
When positioning this unit, you must ensure that the step of the cooling plate
sits on the raised part of the CPU socket (see figure below). Failure to do so
will void the warranty, result in poor cooling, and could damage the CPU.
Correct positioning of the AC4G-D cooling unit for AMD
3. Use the heat sink clip (AMD) or clips (Intel) to clamp the cooling unit
securely to the retention mechanism on the motherboard.
Note for AMD: Fit one side of the clip on manually, then use a screwdriver to
fasten the other side of the clip into position (see figure below).

4. Connect the small connector of the cooling unit to the CPU fan
connector on the motherboard.
C. Bay-unit installation
1. Remove one of the available drive-bay covers from the front of the
PC. (If there is also a thin metal seal over the bay opening, remove
this seal.)
2. Put the USB cable through the opening first, and then slide the
AC4G-D bay unit into the empty bay.
3. Making sure that the front of the bay unit is flush with the front of
the PC, screw the bay unit into position using the 4 supplied screws
(2 on each side of the bay).
4. Connect the bay unit's USB cable connector (female) to the USB
connection on the motherboard (male).
Note: The motherboard USB connector has 9 pins. Make sure that you
position the bay unit's connector correctly so that all 9 pins are connected.
5. Connect the large connector of the cooling unit to the cooling unit
connector on the back of the AC4G-D bay unit (see figure below).
6. Disconnect the front and rear case fans from the PC power supply.
Connect (“daisy chain”) the case fans to each other, and then
connect them to the case fan connector on the AC4G-D card.
7. Verify that the CPU fan and all case fans are unobstructed.
8. Connect one of the cables from the PC power supply to the power
connector on the AC4G-D PCI card.
9. Put the PC cover back on.
Installation is complete.
_______________________________ Operation
In order for any cooling system to work efficiently there must be free air
flow around the PC case. The PC should not be enclosed in a cabinet, and
there should be at least 10cm between the back of the PC and the wall or
1. Connect the PC to the electric mains.
2. Power up the PC.
As the PC powers up, the blue LED on the AC4G-D bay blinks five
times, and then remains alight, indicating that AC4G-D is functioning
3. If required use the switch on the AC4G-D bay to select a different
cooling mode (see next section).
___________________________ Cooling modes
The AC4G-D can run in any of four modes, which are summarized in the
table below. The mode is controlled by the switch on the front of the
AC4G-D bay.
Table 1: Cooling modes
(Default) Recommended for most home and office
In Extra-quiet mode (see graph below) AC4G-B allows a
small temperature increase (∆T) before turning the fans
on. This minimizes fan noise, while maintaining a
significant cooling advantage over conventional coolers.
Quiet and Cool modes offer a balance between maximum
CPU cooling and minimum fan noise.
In Extra-cool mode, cooling begins whenever CPU
temperature begins to rise. The result is an extra-cool
CPU, with slightly increased fan noise.
Note that under normal PC use all modes are safe, and provide
significant cooling and noise-reduction over typical cooling
The LCD display
When you switch your computer on, Mode 1 (Extra-quiet) is activated by
default. The AC4G-D LCD display shows the temperature of the CPU and
the current fan level.
Note: Fan level (or speed) is not the same as mode. Each of the four modes
controls fan speed in a different way, but each uses all four fan levels. If you
notice that fan level is continuously high, you may decide to switch to a cooler
Switching between modes
1. To change modes, press the mode switch for half a second or more.
The LCD display changes to display the current mode.
2. To change modes, press the mode again, repeatedly, to toggle
through the four modes. When you reach the required mode, let the
button go.
After a few moments the LCD display changes back to its regular
temperature/level display.
__________________________ Troubleshooting
The blue LED on the AC4G-D bay is on continuously during normal
operation. A different state indicates a problem.
Table 2: Blue LED status summary
Normal operation. All systems OK.
AC current is not reaching AC4G-D PCI card.
Check the connection between the PC power supply and the
power connector on the AC4G-D PCI card.
CPU fan stalled, may be jammed. (Blinking is preceded by a
screen warning.)
Short circuit in one of the fan connections (CPU or case fans).
In the unlikely event of the case fans drawing more than 1
Amp, disconnect one or more case fans from the installation
(and run them directly from their designated power supply).
