Installation and mounting manual for EK-FC 5850 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 or our home page.
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. The use of an algaecide and corrosion inhibitors is always recommended for any liquid cooling system.
STEP 1: GENERAL INFORMATION. Sample picture of RADEON HD 5850 graphic card.
STEP 2: PREPARING YOUR GRAPHIC CARD.
1. REMOVING STOCK COOLER: Remove encircled
screws:
STEP 2 cont.: PREPARING YOUR GRAPHIC CARD.
1 cont.. REMOVING STOCK COOLER. Remove all encircled screws. All heat sink
assembly screws and backplate should be removed. There are 14 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:
http://www.arctic-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.)
5. PLACING THERMAL PADS ON PCB. Place thermal pads on chips so that
numbers on chips match size of thermal pads. Thermal pad number 2 will have
to be cut by user to match all small mosfet 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.
6. PLACING STANDOFFS ON BLOCK. Standoffs are obligatory to make this
block fully functional. 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.

7. PLACING BLOCK TO GRAPHIC CARD. During this process please make sure you align
holes on PCB with holes on block. Also pay attention not to use too much force by
pressing block down to PCB. Chips are prone to cracking.
8. ATTACHING BLOCK TO GRAPHIC CARD. Please place back stock backplate without
retention backplate of the GPU. By using Philips screwdriver screw in enclosed M3x6
screws. Do not use stock retention backplate. EKWB recommends start screwing the
screws around the GPU core and continue outwards.
STEP 3: CHECKING FOR CONTACTS
Temporarily r emove the water blocks 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 5 and 8 to reattach the block applying more or less pressure to the areas where you have found it necessary.
STEP 4: POSITIONING FITTINGS
Please use spacer on copper base (see sample picture). Screw in the fittings and plugs (please use spacers only on copper base), attach the liquid cooling tubes and connect the
water-block(s) into the cooling circuit. EKWB recommends using high flow fittings with the EK-FC 5850/5870 series water blocks. To ensure that the tubes are securely attached
to the barb/fittings, please use hose clamps or an appropriate substitute. The use of an algaecide is always recommended for any liquid cooling system.
You can use any hole as an inlet/outlet hole.
STEP 5: INSERTING CARD IN YOUR PC CASE
Carefully lift your card with installed block and insert it in your PC case. Bear in mind that your card suddenly withstands extra weight thus again be very careful not to bend it or
cause any other unneeded moves that might damage your card or block during installation.
