Pump Connection
An external 12 Volt DC pump can be
connected to the unit for speed control.
The maximum available amperage is
2.2A.
CAUTION: This product
can be used with a single
!
12VDC pump with a maximum amperage of 2.2A.
POWER: Connection from
power supply, 12VDC
FAN: Radiator fan connections (2.0A max per
plug, 4.5A total)
TEMP: Temperature sensors
shown on the front display
Power Connection
The temperature sensors and ATX lead
may come pre-connected to your unit.
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).
CAUTION: The total com-
bined amperage of all fans
!
connected to the unit can not
exceed 4.5A. The maximum
load on a single fan header
is 2.0A.

Flow Meter Connection
The cooling system can show values
for one Koolance INS-FM16, INSFM17/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”.)
ATX Pass-Through Lead
The ATX pass-through lead is
responsible for sending the shutdown 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.
To Motherboard
From Cooling
Unit
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.

which is typically 5-10°C (9-18°F) lower than the actual heat source. This difference must be considered if adjusting alarm/shutdown temperatures. Setting
alarm/shutdown modes at too high of temperature can eliminate this feature’s
effectiveness. The default Koolance settings are designed to help compensate
for differences in temp.
or press ◙ to configure this fan channel:
CAUTION: Fan percentages are based on PWM duty. Fans will not operate
if set too low. Some types of fans may also not be compatible with the PWM
program and will only operate reliably at 100%.
