Arctic Cooling NV 6 and ATI 1 VGA Silencer
 

Overall, I am very impressed with the cooling power of the VGA Silencer
from Arctic-Cooling. The Arctic-Cooling VGA Silencer is performing very
well during the testing. The design of this VGA Cooler is very stylish and
nice. In a well ventilated case, it does a much better job of cooling than
the stock heat sink, with fan. I have to say that this may be the air
cooled solution for everyone. You can run the VGA Silencer silent, and it
does a very good job. Furthermore, by using it will add more
overclockability to the VGA Card. But, there is some downside of the VGA
Silencer which is takes up to two PCI slot spaces after installing it. I
don't think this will be a problem since most of the user would not use
their entire PCI slot. Highly Recommended for this VGA Silencer from
Arctic-Cooling.
