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:

Parallel Loops
Parallel loops are normally used to help accommodate water blocks with
significantly disproportionate flow restriction. They can become quite complicated,
and if not well-planned, may lower performance through added bottlenecks and
pressure drop.
One suggestion for parallel loops is to reduce tubing size when splitting. Ideally,
the hose area going into the splitter will be roughly equal to (or slightly lower than)
the combined hose area coming out. For example, 3/8” (10mm) tubing split into
two 3/8” (10mm) paths would lose more pressure than splitting from 3/8” (10mm)
into two or three 1/4” (6mm) paths.
If you are considering a parallel flow path, we would encourage you to experiment
with different setups. There may be more optimal configurations than the example
shown below.
