If not, connect them per the diagram
above.
Connect a 12 Volt 4-pin Molex plug from
the power supply to the power connection
on the rear of the unit.
Fan Connection
This unit has three connections to
power radiator fans. Multiple fans can
be combined into a single plug. (A fan
wiring harness is optionally available from
Koolance).

The total com-
bined amperage of all fans
connected to the unit can not

ATX Pass-Through Lead
The ATX pass-through lead is
responsible for sending the shut-
down signal if any sensor reaches the
preset shutdown temperature (See
Display Panel
for configuration).
There is no polarity direction with
the ATX lead. Connect the male ATX
power lead from the cooling unit to
your computer’s main chassis power
button.
Connect the female ATX power lead from
the Slot Adapter to the motherboard’s power
switch connection (often marked “PWRSW”,
“PWSW”, or “PWBT”).
This is the connection that would normally
receive the chassis power button directly.
