Since I was only sent one cooler, I didn’t have a DDR2 or DDR3 module that I really wanted to remove the heatspreader, since once removed they usually can’t be reinstalled. So I used a DDR stick that had the heatspreaders removed once before. Some heatspreaders are harder to remove than others. BE CAREFUL!!
After removing the heatspreaders, remove any remaining goop from the chips. If isopropyl alcohol won’t cut the adhesive, I use a xylol-based household cleaner, either “Goof-Off” or “Oops”. These leave a residue behind, so clean the chips with alcohol and a lint-free cloth afterward.
Take a #1 (small) Phillips head screwdriver and remove the six screws from the cooler. Clean the insides of the heatspreaders and the heatpipes with alcohol. Apply included thermal compound to the heatpipe channels on each heatspreader.
There are two sizes of thermal tape included with the cooler. The thicker of the two is for memory modules with chips on only one side of the PCB. The thinner is for dual-sided memory. Remove the strips from one side of the tape and apply the tape to the inside of each heat spreader. Remove the remaining strips. Place the memory module on one of the heatspreaders, place the heatpipes in the channels, and place the other heatspreader on top of the memory module.
Replace the screws, and you’re done.
