Annihilator Inlet and Outlet Ports

G1/8 ports configuration:

6 ports G1/8 are available for low profile server cooling solutions. Center ports are INLET ports; any of the other four can be used as OUTLET ports. Ensure that all other non-used ports G1/4 and G1/8 plugs are in place and tightened firmly.

Diagram showing G1/8 port configuration with 6 ports. Center ports are labeled 'Inlet', and other ports are labeled 'outlet'. It indicates that non-used ports G1/4 and G1/8 should be tightened with plugs.

G1/4 ports configuration:

3 ports G1/4 are available for normal use of the water block for workstations. The center port is INLET; the other two can be used as OUTLETS. Ensure that all other non-used port plugs G1/8 and G1/4 are in place and tightened firmly.

Preparing CPU and Applying Thermal Grease (TIM)

Cleaning the CPU:

Wipe the CPU's contact surface using a non-abrasive cloth or a Q-tip.

Applying thermal compound:

EK recommends a blob or line method of applying the enclosed EK-TIM Ectotherm™ thermal compound to the CPU heatspreader (IHS). The quantity of about pea size is generally sufficient. There is no need to cover the whole IHS. Applying too much thermal grease can negatively impact cooling performance.

Installing the Water Block

1. On most motherboards, the EK-Annihilator Pro ILM can be successfully installed with the motherboard already fitted to the computer chassis. However, it is best practice to place the motherboard on an even surface with the front side facing up.
2. Install the CPU and apply TIM (thermal grease) as shown in STEP 5.
3. Align the water block above the LGA 3647 socket on the motherboard with the pre-installed CPU.
4. Tighten the screws using the 4mm Allen Key in a cross pattern.

Tightening sequence:

Tighten the screws in a cross-pattern sequence using the 4mm Allen Key. Screws 1 and 2 must be tightened until they hit the limiter and cannot turn further. Do not overtighten screws 3 and 4.

Diagram illustrating the cross-pattern tightening sequence for screws 1, 2, 3, and 4, with notes indicating that screws 1 and 2 should be tightened until they hit the limiter and not overtightened, while screws 3 and 4 should not be overtightened.

Connecting the Water Block to the Cooling Loop

Connecting G1/8 fittings with tube:

Carefully identify the direction of flow in your circuit. EK recommends the use of EK-HFB Fitting 6mm G1/8 and EK-Tube ZMT 6/9mm Matte Black tubing.

1. Install Barb [1] to the CPU block using the 3/16 Allen Key.
2. Mount Clamp [3] to the tubing [2].
3. Mount the tube [2] to the barb [1].

Connecting G1/4 fittings with tube:

Carefully identify the direction of flow in your circuit. EK recommends the use of EK-HFB 10 mm barb fittings and EK-Tube ZMT 10/16mm.

The use of biocide containing and corrosion inhibiting coolant is always recommended for any liquid cooling system. EK recommends using EK-CryoFuel.
