Installing the Direct Liquid Cooling module
Prerequisites
Never uninstall the Direct Liquid Cooling (DLC) module from a processor unless you intend to replace the processor or system
board. The DLC module is necessary to maintain proper thermal conditions.
1. Follow the safety guidelines listed in the Safety instructions.
2. Follow the procedure listed in the Before working inside your system.
3. Remove the air shroud.
4. Remove the expansion card riser.
5. If installed, remove the processor dust cover.
NOTE: Ensure anti-tilt wires on the DLC module are in the unlocked position.
NOTE: The recommended maximum operating pressure is 15 psi (diverter opens at 15 psi).
Steps
1. Align the DLC module with the standoff screws on the system board. Place the module on the processor slot and set all the
anti-tilt wires to locked position (outward position).
NOTE: Ensure that the DLC tubes and liquid cooling leak detection cable are placed towards the rear of the system.
2. Using a Torx #T20 screwdriver, fully tighten the captive screw all the way down before moving to the next screw (on
one-screw-at-a-time basis).
