Vizo Sleet Copper Cooling Components
 

The VIZO copper coolers do help reduce temperatures on RAM and VGA RAM chips. As with any passive cooling device, proper airflow is a must. The double-sided tape held the finned heatsinks in place. Also, the DDR cooler is held in place with double-sided tape and 2 clips. Everything felt like it was securely in place and I wasn't worried about the copper falling off and possible shorting out my system.

So if you are in the need for copper heatsinks, give the VIZO series of copper coolers a try. They add a nice bling factor by looking extremely sharp, and also copper is a much better choice then aluminum for heat dispersion.
