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
furniture.
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
properly.
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
Setting Mode Description
1
Extra-
quiet
(Default) Recommended for most home and office
situations.
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.
2 Quiet
3 Cool
Quiet and Cool modes offer a balance between maximum
CPU cooling and minimum fan noise.
4
Extra-
cool
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
methods.
