CNT-VDBx Video Block Bridge Guide v 1.0

NOTE: To make installation easier, install the video cards with their liquid cold
plates into the computer before adding bridge blocks. The loop must be dry during
installation. Do not add coolant until the bridge blocks have been installed.

Installation varies slightly between bridge block models, but all share common
steps.

Using a hex driver, remove both fitting
blocks (and their underside o-rings) from
each video cold plate.

2

While keeping the o-rings
in their grooves, place each
bridge block across the video
cold plates. Carefully insert
the provided hex assembly
screws, and hand-tighten
them.

Be careful not to cross-thread
the hex screws, or it may
damage the cold plates!

Follow the below diagrams for
the desired flow path: serial or
parallel. Note where the plug
caps (blue in the diagrams) are
installed to seal the loop.

G 1/4 BSPP threaded tube
fittings must be installed on the
inlet and outlet locations.

CNT-VDB1 and CNT-VDB2

Place the o-rings included with your bridge
blocks into each of the grooves beneath it. This
must be done for both bridge blocks.

Makes sure these o-rings stay evenly within
their grooves throughout installation.

CNT-VDB2 in Series CNT-VDB2 in Parallel

The included long plug is only used for
serial flow. Carefully insert this into the
right side bridge block as shown.

If the plug does not insert easily,
temporarily loosen the hex assembly
screws on the bridge block for this
installation step. Do not force the plug
or it may damage its o-ring!

CNT-VDB3 uses two specialized long plugs for serial configurations (shown

in previous diagram).

Longer Plug 1 (Left Side) Longer Plug 2 (Right Side)

The included long plugs are only used for
serial flow. Carefully insert them into the
bridge blocks as shown in the previous
diagram.

If the plugs do not insert easily, temporarily
loosen the hex assembly screws on the
bridge blocks for this installation step. Do
not force the plugs or their o-rings may

become damaged!

CNT-VDB4

T o maintain coolant pressure, CNT -VDB4
places two video cold plates in parallel
linked by a serial connection.

There is only one configuration available
as illustrated in the diagram to the left.
