Installation and mounting manual for EK-FC460 GTX water block 

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 picture of NVidia GeForce 460 GTX PCB design 

STEP 2: PREPARING YOUR GRAPHIC CARD 
1. REMOVING STOCK COOLER. 

Remove all encircled screws. All heat sink assembly 

screws and retention plate should be removed. There are 4 screws on the back of the 
graphic card.  

2. CLEANING THE PCB. Carefully detach the original heat sink after removing all 

fasteners securing it to the board and bracket. Wipe off the remains (by using non–
abrasive cloth or Q-tip, 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 GPU with for example Arctic Cooling MX2 ™ or 

MX3 ™ thermal compound. Follow this link:

cooling.com/catalog/images/install_mx2_retail.pdf

 

 

for detailed 

instructions. 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, which have to be 

placed on chips (PLEASE REMOVE FOIL ON BOTH SIDES OF THERMAL PADS PRIOR 

TO INSTALLATION. WARNING: DIMENSION BELLOW ARE SCALED.) All thermal pads 

are 1mm thick.  
 

 

   
                      

 

STEP 3:  INSTALLING WATER BLOCK 
1. PLACING THERMAL PADS ON PCB. Place thermal pads on chips so that 
numbers on chips match size of thermal pads. Thermal pads have to be cut by 
user to match all small chips (EKWB made sure users have more than enough 
pads to cover all surfaces that need to be covered to make block fully function). 
You can also use small drop of thermal grease on chips to make thermal pads 
more adhesive. 

 

 

2. PLACING STANDOFFS ON BLOCK. Please use small amount of thermal 
grease on standoffs and glue them so they are concentric with mounting 
holes. Once they are stuck to block be careful not to move them. 

 

 

 

Attention: Some cards, don't 
have RAM here.
