This Australian site named AtomicMPC has a GTX480 and has torn it apart and shown us how to do it in pictures:

http://www.atomicmpc.com.au/Gallery/170368,nvidia-gtx480-disassembly-guide.aspx/1

I still really like the look of the card, but oh my god that is a big heatsink and a rather big core. And a 21.6 watt Delta fan? Ouch, that'll probably be loud. Then again, its not like the competition has quiet fans on the high end either.

Edit: Nvidia asked the site to take down the images. They said it will be back up in a couple days when the NDA is up. Here is a link to the full article: http://www.atomicmpc.com.au/Feature/170367,nvidia-gtx480-disassembly-guide.aspx

Edit 2: Here is a link to a picture I saved: http://pixelsmashers.com/wordpress/wp-content/uploads/2010/03/20100324113523_IMG_0197-copy.jpg I won't image it due to size as its not a small picture. A smaller version of it can be seen a few posts down. And there are a couple more images here http://www.hexus.net/content/item.php?item=23088 (thanks Pkirk618)

Wow, not much left to the imagination. Curious to see a waterblock for this card.

Looks like they took the pictures down. Damn. I did manage to save one of them.

Saw the pics while they were up, really dig the cooler design. If it turns out to be hot as hell, at least something has been learnt from it :D
 
That card is without a doubt the best physically appealing video card I've ever seen. If performance matches I may just buy one.

Its too bad AIBs will make it look like shit with their terrible decals.
 
There will be reference coolers.

Badass looking card for sure. But will performance be good enough? And heat bothers me. If it really is that hot, thats scorching. And not something I like. The GTX 260 got damn hot as well.

I mean the terrible decals they add to the reference coolers. I've pretty much never seen an AIB decal I like. They all look cheesy in a bad way. From poorly done CG girls to ugly random designs.
 
Hey it looks like they finally got smart and cut out the place on the PCB where the metal bracket goes, I bet This will provide 5-10% or more cooling. Kudo's to Nvidia for innovation on this part.

I hope there new card does well, We need some competition in the VC marketplace. I hope it dirves the 5870 prices down.

+1 All the pics looked very good and the the heatpipe cooler being seperated from the shell appeared to be very solid.

they did this with the 8800gtx
 
My god the chip is big. It's like the size of a cpu package. Can't wait for benchmarks...

No they didn't.

MY BAD! They have still done this before, with the 9800GX2.

edit: didn't see your post brent, yea I know they did this with the 9800GX2, which is a respin of the 8800 line up. Got confused and didn't re-check which card did this before.

This doesn't look good at all. Look at all that surface area to dissipate heat, this thing might just be able to heat your room in the winter. I was hoping for better competition from Nvidia but if this is the best they can come up with after 6 months of failing then we better get used to prices climbing up again.
 
Why the use of these huge, thick fins? Seems like using thinner fins would greatly increase cooling area, thus moving all the heat those 3 billion transistors are bound to be producing away faster, make it quieter too...

won't be quiet with a 22watt fan, don't know about the thicker fin's, but we will see if this design works, Nvidia seems to think so and they usually come out with some sick HSF designs.

They aren't using huge, thick fins. Look at this picture:

GTX480nude2.jpg


The thick fins that you see from the top view are *covering* the actual heatsink fins.

But damn, its a little alarming to see such a beastly cooler as the stock reference cooler. Makes you wonder what after market cooling is going to look like :eek:
 
the thin fins are packed so tightly together. turbulance and air noise are going to be terrible.
 
Noise might be terrible, but cooling is probably going to be good. But dang, never seen a heatsink design like this, even in most after market coolers. makes you wonder how big a water cooling block has to be. Heck, you can probably even mount a CPU cooling block on this thing and get away with it, just because it's so big.

They're using a squirrel cage fan which has very high backpressure, meaning that it will be able to force air through narrow channels with relatively little effort (low speeds). It shouldn't be any noisier than other cooling solutions out there.

Also, air turbulence needs some room to form, having narrow channels by definition means you get nice laminated flow :)

TDP is 250W but from the looks of it 15% extra should not be an issue. Oh and memory ICs are the same ones as the ones found on HD 5870 so say hello to 250Gb/s of bandwith :cool:
