IMO, they should put a shroud around the fan, to keep the air from spilling out sideways.
And they're gonna have to figure out RAMsinks too, though they may just go right in underneath it.
And that CNPS8700 looks like a beast. The 7700 was ****** huge, I couldn't believe how big/heavy it was when I installed it in a friend's computer.
Yep, GPU cooling is problematic... and every setup is different!
In my (ahem) case, I run a Tuniq Tower in a north-south orientation. Its integrated 120mm fan sticks out the bottom about an inch or two, which blows air over my passive NB sink and the RAM sinks on the backside of my video card. My Sytrin VF-1 Plus GPU cooler has a powerful squirrel cage blower that channels air through the GPU heatpipe radiator and outward along the front side of the card for those RAM sinks.
Here's a
benchbuild pic that will give you an idea of what I'm talking about. I don't have my ATI 9800 Pro/Sytrin VF-1 installed in this shot -- just a passively cooled ATI 9200SE that I use on the bench... but it exemplifies the direction of the air flow...
I know this isn't the best arrangement -=- but such is life. Everything is a compromise with GPU coolers!
Having said that, I don't see how this VF1000 cooler can possibly live up to the hype. By itself, I don't *think* it'll do squat for cooling! Then again, I suppose it all depends on what other measures you put into place, e.g lots of other fans and sinks.
Only time will tell, yes?
