First thing u gonna do is take the old cooling of it. U are going to do this by using a hairdryer on the heatsink so the thermal pad will melt a little so u can take it off. U might wreck your card if u don't do it this way. Now after u have done this, just check if everything will fit, and install the bracket and stuff. Also check if the fan connector is the same, when I installed a VGA Silencer on my GeForce 3 Ti 500 I had to solder the connector of the stock fan to the wires of the VGA silencer. Then install the RAM heatsink, I suggest u don't use the AS5 here because it is a conductor. U better use Arctic Alumina, with some glue. Now do some AS5 on the core and put the VGA silencer on. Doublecheck if everything is in the right place and use the blue clip to tighten it to the board. Don't forget any washers if there are.
