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.ekwaterblocks.com

 for updates. 

Before installation of this product please read important notice, disclosure and warranty conditions printed on the back of the box. 
The barb hose fittings require only a small amount of force to screw them in; otherwise the high flow fittings might break. These fittings do not need to be tightened with much force because the 
liquid seal is made using o-rings.
 

STEP 1:  GENERAL INFORMATION Sample photo of ASUS CROSSHAIR III FORMULA PCB design

 

 

STEP 2:  PREPARING YOUR MOTHERBOARD 
1. REMOVING STOCK COOLER. Remove all encircled screws.

 All stock 

cooler assembly screws should be removed. There are 6 screws on the back of 

the motherboard. 

 

 

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 does not recommend using any liquids for removing paste. 

                                          

                                         

 

3. APPLYING THERMAL COMPOUND 

Apply thermal compound: lightly coat the Northbridge and Southbridge with 

for example Céramique™ thermal compound. Follow this link 

http://www.arctic-

cooling.com/catalog/product_info.php?cPath=39_&mID=127&language=en 

for 

detailed instructions. EKWB recommends non-conductive MX-2, which should 

be applied in cross form for best performance (see sample picture). 

4. CUTTING THERMAL PADS. 

 One thermal pad (90x15x1 mm) and one thermal pad 

(90x7,5x1 mm) are enclosed with your water block. You will have to cut out parts from smaller 

thermal pad in order to cover all the surfaces that are left exposed on mosfets. (WARNING: 
DIMENSIONS ON PICTURES BELLOW ARE SCALED!) 

           

          

    

5. PLACING THERMAL PADS ON MOTHERBOARD. Place thermal pads you cut on PCB as shown on picture bellow. 
    (PLEASE REMOVE FOIL OF THERMAL PADS PRIOR TO INSTALLATION.)
