Cooler & Tubing Configuration
There are a vast number of methods for configuring hoses in a liquid cooling system
(serial, parallel, combinations, alternating components, etc.). There is no single
“correct” way! As long as coolant is flowing and you are satisfied with your device
temperatures, it’s an acceptable configuration.
Similarly, the maximum number of water blocks allowed in a system will depend
upon your own configuration and thermal requirements. It’s common to see five or
more coolers in a Koolance system, but the limit is at what temperature you are
comfortable with.
Serial Loops
A basic serial loop is recommended for *almost* every situation. Provided your
cooling system has a radiator of sufficient size for your total heat load, expect only
a minor difference between outlet and inlet temperatures. In computer cooling,
a delta of less than 1 to 3ºC (1.8 to 5.4ºF) is typical for the heat exchanger. This
means for most loops, you don’t need to worry about “hot water” moving from
one block to the next. It gets only a little warmer throughout the entire loop.
Generally, series is the simplest and most effective configuration. Each device is
daisy-chained to the next, usually starting with the most temperature-critical:
Installation
AC Power Option
To power the cooling unit with
110VAC/60Hz or 220VAC/50Hz,
an optional power inverter is
available from Koolance. This
connects to the cooling system’s
rear 9-pin plug.
Temperature sensors and the ATX
shut-down lead are connected
directly to this adapter.
This cooling unit has the option to use
either a 120mm or 140mm (25mm
thick) fan up to 0.3 Amps. A separate
Koolance mounting bracket, fan, and
grill are needed to install a 140mm
fan.
To replace the fan, simply loosen the
two rear enclosure screws and lift up
on them. This allows access to the
radiator fan and wire connection.
Swapping the Fan
Mounting Brackets
Additional steel mounting brackets are
sold separately for this cooling system.
