ekwb EK-FC7990 Installation And Mounting Manual

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
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 corrosion inhibiting coolants is always recommended for any liquid cooling system.

should be removed. There are 8 (eight) screws on the back of the graphics card.

3. APPLYING THERMAL COMPOUND.

remains (by using non–abrasive cloth or
original thermal compound until the components and
circuit board are completely clean. Apply thermal
compound: lightly coat both AMD GPU chips as well as
PLX bridge chip with - for example - GELID GC-Extreme™
thermal grease. EKWB recommends to apply thermal
grease in cross form for best performance (see sample
picture).

enough pads to cover all surfaces that need to be covered to make block fully functional). EKWB 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) in order to even
further improve the thermal performance of the EK-FC7990 series water block. Repeat the procedure on the back side of the PCB.

STEP 2: PREPARING YOUR GRAPHIC CARD.
1. REMOVING STOCK COOLER: Remove encircled screws on the
bracket (required only on certain models) in order to remove the
bracket:
2.cont.: Remove the screws attaching the backplate to the
circuit board. Remove the self-adhesive heatsinks from the
circuit board as well! This step may require some force as
adhesive might hold the heatsinks firmly to the PCB
components. We recommend users to slowly and carefully pry
the heatsinks from the PCB using bare hands (tool-less
approach).
Your block comes with thermal pads, some of which are already pre-cut. Others
