Filling & Maintenance

Under normal circumstances, the liquid coolant does not require replacement. However,

if it becomes contaminated, unclear, or signiﬁ cantly changes color, it must be replaced. A

Koolance “drain valve” (sold separately) is recommended to make that process easier.

If you are upgrading or removing a cooling block in your system, please follow the

instructions below.

Adding Coolers & Maintenance

CAUTION: Any time a hose is disconnected with coolant still inside,

leaking can occur. Before doing so, it is highly recommended to

remove all computer hardware and the power supply. It can also be

beneﬁ cial to keep a large towel directly beneath the work area (within

the chassis) to absorb any free liquid.

Radiator Performance

Over time, dust will accumulate on the radiator. While the cooling system may

continue to operate in this condition, performance can decrease. To keep the

system clean, check the radiator periodically (through the top fan grill) and use

a can of electronics air cleaner if necessary.

A binder clamp (available at ofﬁ ce supply stores) is helpful for keeping a hose folded

while removing or adding coolers. Even so, pressure within the cooling system is

such that liquid will not easily ﬂ ow out unless relieved elsewhere-- for example, by

opening the reservoir reﬁ ll plug.

Bend the hose directly before and after the section to be worked on. Place a binder

clamp on both bends, or tie them in this position to help avoid ﬂ uid loss. There will

be some liquid exposed; do not operate on the cooling system in this manner near

or above electronic hardware.
