This product is intended for installation only by expert users. Please consult with a qualified technician for installation. Improper installation may result in damage to your equipment. EK Water Blocks assumes no liability
whatsoever, expressed or implied, for the use of these products, nor their installation. The following instructions are subject to change without notice. Please visit our web site at www.ekwb.com for updates. Before
installation of this product please read important notice, disclosure and warranty conditions printed on the back of the box.
Before you start using this product please follow these basic guidelines:
1. Please carefully read the manual before through before beginning with the installation process!
2. Please remove your motherboard from the computer to assure safest mounting process in order to prevent any possible damages to your CPU and/or motherboard’s circuit board (PCB).
3. The EK High Flow and EK-PSC type fittings require only a small amount of force to screw them firmly in place since the liquid seal is ensured by the rubber o-ring gaskets.
4. The use of quality, market proved corrosion inhibiting coolants is always strongly recommended for any liquid cooling system.

STEP 2: PREPARING YOUR MOTHERBOARD
1. REMOVING STOCK COOLER. Remove all encircled screws. There are 6 screws
on the back of the motherboard that needs to be removed in order to remove the
factory installed MOSFET/NB- as well as SB cooling solution.
2. CLEANING THE PCB. Carefully detach the original stock cooler after removing all
screws securing it to the board. Wipe off the remains (by using non–abrasive cloth or
qtip , as shown on sample photo) of the original thermal compound until the components
and circuit board are completely clean. EKWB recommends the use of denatured alcohol
for removing TIM leftovers.
3. APPLYING THERMAL COMPOUND. Apply thermal compound: lightly coat the
Intel Z77 PCH (SB), PLX PEX 8747 and LSI SAS2308 with electrically non-conductive
thermal grease - for example Arctic Cooling MX-2 ™,MX-4 ™ or GELID GC-Extreme
™. EKWB recommends to apply thermal grease in cross form for best performance
(see sample picture).
4. CUTTING THERMAL PADS. Your block comes with thermal pads, some of which are
already pre-cut. Others have to be cut to smaller chunks in order to cover all the VRM
components such as MOSFETs and drivers. PLEASE REMOVE THE PROTECTIVE FOIL
FROM BOTH SIDES OF THE THERMAL PADS PRIOR TO INSTALLATION.
Replacement thermal pad: Thermal PAD A 1,0mm - (100x16mm) [EAN: 3830046996626]
5. PLACING THERMAL PADS ON MOTHERBOARD. Place thermal pads you cut on PCB as shown on picture bellow (PLEASE REMOVE THE PROTECTIVE FOIL FROM BOTH
SIDES OF THE THERMAL PADS PRIOR TO INSTALLATION). EK recommends using small drops of electrically non-conductive (for example: Arctic Cooling MX-2 ™,MX-4 ™ or
GELID GC-Extreme ™) thermal grease on each phase regulator (that is being covered with thermal pad; see picture below) in order to even further improve the thermal
performance of the EK-FB ASR Z77 Extreme11 series water block.

STEP 3: PREPARING YOUR WATER BLOCK
1. PLACING SB BLOCK ON MOTHERBOARD. Place the EK-FB ASR Z77 Extreme11 series water block with pre-installed 2.1mm standoffs kit gently to the motherboard or vice
versa. Make sure that mounting holes are aligned.
STEP 4: ATTACHING BLOCK TO MOTHERBOARD
STEP 5: CHECKING FOR CONTACTS
Prior to fastening the screws please make sure the mounting holes on the motherboard’s
circuit board are aligned with water block.
Use 6 (six) M2.5x4 DIN7985 and washers: Tighten the screws, beginning near the center of
the board and continue evenly outwards. EK recommends installing all screws losely first
and only then start fastening them. Do not use excessive force when tightening the screws!
Use the enclosed screws and washers as shown in picture below:
Temporarily r emove the water block to check for uniform surface contact
between the block and the components. Note the pattern of contact on a piece of
paper. Then repeat steps 3 and 4 to reattach the block applying more or less
pressure to the areas where you have found it necessary. Note that there is no
need for perfect thermal pad imprint on the inductors/coils (mentioned in STEP2)
6. POSITIONING FITTINGS AND CONNECTING TO WATER CIRCUIT
Attach the liquid cooling tubes and connect the water-block(s) into the cooling circuit. EKWB recommends using EK-PSC compression fittings with the EK-FB ASR Z77 Extreme11
series water block. You can use any opening as an inlet/outlet port. Plan your tubing routing in advance!
