The CORSAIR Hydro X Series XD3 RGB Pump/Reservoir Combo features a high-performance DDC PWM
pump, integrated RGB lighting as well as in-loop temperature sensor to drive even the most
compact custom cooling systems.
The XD3 RGB pump/res combo includes all the mounting hardware necessary including a plug
tool, ATX 24-PIN PSU jumper, a G1/4” TEMPERATURE SENSOR PLUG, and some CORSAIR G1/4” PLUGS.
You’ll also need a Phillips-head screwdriver, a CORSAIR iCUE COMMANDER PRO, CORSAIR XL5
coolant and a filling flask.
There are a variety of mounting configurations available to you depending on your system layout.
You can use the included 120mm or 140mm adapter plates to mount the XD3 directly to a fan,
radiator, or your chassis.
And the included perpendicular mounting bracket can be used to change the orientation of the
XD3 RGB if necessary.
Once you’ve decided on the mounting solution you’d like to go with, it’s now time to
pick the inlet and the outlet for your loop.
Looking directly at the XD3 RGB, the G1/4 ports on the left must be used as outlets
and the G1/4 ports on the right may be used as inlet ports.
The top port will serve as a fill port
and the bottom port is where we recommend you install the temperature sensor.
Once you’ve decided on your flow configuration, we should now take a look at connecting power
and lighting.
The XD3 RGB uses a single MOLEX connector to power the pump directly off of your power supply.
The 4-pin fan connector serves as a tachometer that will report and control pump speed,
If you’re using the XD3 RGB with a CORSAIR Commander PRO, we recommend connecting this
to port #6.
Connect the male three-pin RGB connector to an available lighting port on your Commander PRO.
“Next, connect the two-pin temperature probe connector to temp port #1.
If you have any other Hydro X components, you can daisy-chain them to the XD3 RGB using
the female 3-pin RGB connector.
Once you’ve assembled your loop, you’ll need to fill and prime your XD3 RGB until the loop is full.
To do this, disconnect all the power cables from all system components except for the XD3 RGB’s
MOLEX power connector.
Turn off the power supply and connect the included 24-pin PSU jumper bridge.
Fill the XD3 RGB’s reservoir through the top fill port leaving approximate half a centimeter
from the top of the reservoir.
Turn on your power supply by flipping the ON switch. Your XD3 will power on and coolant
should start flowing through your loop. MAKE SURE to turn off your power supply before
the reservoir is empty.
The XD3 RGB has a fairly small reservoir, so the filling and priming process may need
to be repeated multiple times until the loop is full.
Let the loop running for about 24 hours to remove any trapped air and leak test the system.
Once you’re satisfied that the system won’t leak, you can reconnect your PSU to your other
components and start your system normally.
Just like other Hydro X components, the XD3 pump/reservoir combo features RGB lighting
and a Hydro X pump performance preset.
In the lighting setup tab for our Commander PRO, we’ll make sure that the XD3 is part
of the chain of Hydro X devices in our loop.
Once our lighting setup is complete, we can apply a variety of different custom lighting
effects to our components.”
In the performance tab for our Commander PRO, we’ll assign the Hydro X pump preset to
our XD3 RGB connected to port #6
This preset requires the temperature probe we installed earlier and will adjust the pump
speed based on coolant temperature.
And while we’re at it, we’ll also make sure to assign the Hydro X fan preset to the
fans in our system.
And that’s it! The compact XD3 RGB Pump Res Combo makes it easier than ever to build your own Hydro X
loop in more compact spaces.
