EK-CPU Lignum Water Block User Guide

LGA-2011(-3) / 2066 Socket Motherboards

STEP 1

Prepare the foil bag with the mounting mechanism, which is enclosed with the CPU water block delivery. Install four (4) specific LGA-2011 M4 thumb screws into the four M4 threaded stubs on the LGA-2011 socket integrated latch mechanism (ILM). The screws are to be installed using no tools (i.e. pliers).

It is recommended to remove the motherboard from the PC chassis before proceeding with installation of the CPU water block because of the space constraint limitations of various computer cases.

STEP 2

Cleaning the CPU: Wipe the CPU's contact surface (by using non-abrasive cloth or Q-tip, as shown on sample photo).

Applying thermal compound: On a clean IHS, apply a line of thermal compound and spread it over the whole CPU heat spreader (IHS) with a credit card or equivalent. The layer of thermal compound must be thin and even in thickness through the whole surface of the IHS. Too thick application could lead to poor performance. This method applies for Thermal Grizzly Hydronaut thermal compound (3830046998477).

STEP 3

Align the water block over the mounting screws on the LGA-2011(-3) motherboard with the pre-installed CPU.

⚠️ Before proceeding with the installation, it is mandatory to remove the protective foil from the backside of the water block.

Place an enclosed compression spring and thumb nut over each M4 thumb screw. Start fastening two thumb nuts at a time, preferably in cross pattern, and do not tighten them fully until all of them are partially screwed in. Then, using your fingers only, screw in all four thumb nuts until you reach the end of the thread.

STEP 4

Placing Wood cover:

⚠️ Before proceeding with the installation, it is mandatory to remove the protective foil from the backside of the water block.

Place Wood cover over the water block. Then, using your fingers only, press Wood cover onto the water block. Do not exaggerate with the force applied.

STEP 5

Tighten the fitting barbs in clockwise direction until the gasket underneath is compressed.

The installation of the CPU water block is now complete.

⚠️ Before proceeding with the installation, it is mandatory to remove the protective foil from the backside of the water block.

With EK-Lignum series water blocks, it is mandatory to use the port that is nearest to the center of the water block as the INLET port. Mixing the ports may result in less than ideal thermal performance of the water block.

LGA-115x Socket Motherboards

STEP 1

If already installed, please remove the motherboard from your computer and place it on an even surface with the front facing down.

STEP 2

Preparing backplate rubber gasket

The enclosed rubber gasket is an essential part of the backplate and mounting system and must be used every time you install this water block on your motherboard.

⚠️ The rubber gasket has a partially cut inner part which needs to be removed when installed on Intel® LGA-115x motherboard. The rubber is held on four places and can be peeled away with hand.

STEP 3

Install backplate rubber gasket and place metal backplate for Intel® LGA-115x socket to the back of your motherboard RIBBED SIDE UP! (facing away from the motherboard). Align the holes on the motherboard with holes on the rubber gasket and backplate.

Carefully rotate motherboard assembly with front side facing up with one hand while holding the backplate and rubber in place with the other hand.

⚠️ Make sure to orientate the rubber gasket to fit past the CPU socket ILM backplate. On certain ITX form factor motherboards, the rubber gasket may need to be trimmed using household scissors.

STEP 4

Install four (4) M4 thumb screws onto your motherboard. It is mandatory to put a 0.7 mm plastic washer underneath each of the M4 thumb screws. Tighten the screws to the metal backplate until you reach the end of the thread. Using tools (such as pliers) is not recommended.

Continue installation by following the instructions on page 8 from STEP 2!

AMD® Socket Motherboards

STEP 1

Replacing the mounting plate: Place the water block on a level surface and remove the four M4x14 DIN 7991 screws attaching the copper base to the top using a 2.5 mm Allen key in counter-clockwise direction.

STEP 2

Replace the Intel® factory installed mounting plate with an AMD® one. You will feel the mounting plate locking into position when placed correctly onto the top.

Reseat the O-ring gasket (57x2.2 mm) into the gap between the mounting plate and water block top.

⚠️ Be careful that the orientation of the copper base is as shown on the picture.

Reinstall the M4x14 screws and tighten them using a 2.5 mm Allen key to screw them in clockwise direction.

STEP 4

Removing of the original plastic hold-down clamps and the factory backplate: Using a Philips-head screwdriver, remove the four UNC 6-32 screws securing the original plastic hold-down clamps around the socket as shown on the sketch. Remove the original AMD® backplate and the hold-down clamps and store them away. See sketch for further part identification.

STEP 5

Preparing backplate rubber gasket

The enclosed rubber gasket is an essential part of the backplate and mounting system and must be used every time you install this water block on your motherboard.

⚠️ With AMD® Sockets, you should use the whole rubber backplate including the inner core.

STEP 6

Install backplate rubber gasket and place metal backplate for AMD® socket to the back of your motherboard RIBBED SIDE UP! (facing away from the motherboard). Align the holes on the motherboard with holes on the rubber gasket and backplate.

⚠️ Please use the correct backplate, depending on your motherboard type (AM3 or AM4).

Carefully rotate motherboard assembly with front side facing up with one hand while holding the backplate and rubber in place with the other hand.
