Gigabyte 6600GT Silent Pipe
 

Gigabyte sent us a sample of their 6600GT Silent Pipe graphics card. This
card uses Zalman cooling to cool
the hot 6600GT chip. Unlike previous total passive cooling solutions,
Gigabyte chose to supply a blower fan with this card,
needless to say this move is very welcome - you need it if you want to cool
the card. Another interesting fact is the memory clock
is slightly higher than the reference specification. Overall, we like this
card, particularly since it's being sold at a lower price than
most GeForce 6600GT cards out there.
