Hmmm, NVSilencer 6 or Zalman all copper for 6600GT?

[Damien]

I plan on getting a 6600GT (pci-e) as a temp. video card, and I'd like to replace the stock cooling. I know the silencer's are very very good, but the zalman looks promising (all copper version). Comes with ram sinks too. Overall, which of these two are better? Any guides/reviews/personal experiences would be nice

thanks guys

edit : This is the pci-e version I mean, as I'm getting an Ultra-D

i love my zalman, dropped my temps. load is never above 43c now, i love it.

From what I've seen the Zalman will offer better temps.
The only advantage I see in the AC is that it will help with air flow if your having problems with case temps.
