The heatsink has holes in the end that allow it to mount in the empty motor slot of the emaxx motor plate. You can use 2 40mm fans( check description to be certain) that should blow down onto the heat sink. Depending on how much space you have the quark can be ontop or underneath as it were, but the flat side of the heatsink needs to be facing the quark either way. As for attaching it- thermal tansfer paste and some long zipties seems to be the prefered method. You can get the fans from either ebay or a pc store- radioshack maybe too. Depending on the voltage of your setup go for either 5v fans or 12v fans, and tap them into the escs battery wires- near to the plug as possible is best I think.
