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.
CAUTION :
The auto shutdown safety feature of this product will not
function without properly connecting the ATX pass-through lead.

Power Connection
The temperature sensors and ATX
lead may come pre-connected to
your unit. If not, connect them per
the diagram on page 11.
Attach the included power harness
to the location on the rear of the
unit marked “Power”. To this,
connect a 12 Volt 4-pin Molex
plug from your power supply.
The cooling system can show
values for one Koolance INS-
FM16, INS-FM17/N, or INS-FM18
flow meter (sold separately). The
use of a flow meter is optional.
Connect a flow meter to the
appropriately labeled plug. (Note:
INS-FM18 should connect to the
plug labeled “INS-FM17”.)
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).
Flow Meter Connection
CAUTION :
The total
combined amperage
of all fans connected to
the unit can not exceed
4.5A. The maximum
load on a single fan
header is 2.0A.

Temperature Sensor Placement
Three surface temperature sensors are
included with this product for monitoring.
Generally, sensors are affixed to water
blocks with metal tape. (Liquid temperature
sensors are also available optionally from
Koolance.)
Sensors should never be placed directly
between a heat source and its water block.
This will interfere with contact and can
damage the sensor or heat source.
