Remove Heatsink
The motherboard or video card should be removed from the chassis in order to install the chipset water block. The mounting screws are inserted from the back side of the board.
CAUTION: Removal of the original heat sink my void your manufacturer's hardware warranty. Please consult the manufacturer if unsure, and keep all original parts in case of a return/RMA. Koolance does not recommend using a water(liquid) cooler on motherboards that lack standard mounting holes, or have heat sinks that are attached with only an adhesive (rather than screws or bolts).
