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 corrosion inhibitors is always recommended for any liquid cooling system.

STEP 2: PREPARING YOUR MOTHERBOARD
1. REMOVING STOCK COOLER.
Remove all encircled screws. There are 8
screws on the back of the motherboard that needs to be removed in order to
remove the factory installed NB/SB/MOSFET heatpipe 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 does not recommend using any liquids for removing TIM leftovers.
3. APPLYING THERMAL COMPOUND.
Apply thermal compound: lightly coat
the
AMD 990FX
(NB) as well as
SB950
(SB) chip with electrically non-
conductive thermal grease - for example Arctic Cooling MX-2 ™ or MX-4 ™.
EKWB recommends to apply thermal grease in cross form for best performance
(see sample picture).
4. CUTTING THERMAL PADS.
Your block comes with one precut thermal pad (90x15x1mm)
which needs to be trimmed a bit in order to fit the voltage regulation area (VRM/MOSFET) on
the motherboard’s circuit board. 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 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 ™ or MX-4 ™)
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 GA
990FXA UD7 series water block.
