So basically the HD5970 is a complete failure as a product. In-effective stock cooling in all regards, lower clocks than HD5870's. Much longer than HD5850's and larger power draw for barely any improvement...
Radeon 5970 Overclocking: The VRM Temperature Bottleneck (anandtech)

| Radeon 5970 Overclocking: The VRM Temperature Bottleneck In our Radeon HD 5970 review, we ran in to some issues when trying to overclock the card to 5870 speeds of 850MHz/1200MHz. At the time this is something we attributed to the VRMs, meanwhile AMD suggested that it was cooling related, and that we should manually increase the fan speed. As it turns out, we were both right, we just didn’t have the tools at the time to properly identify and isolate the issue. Late last week we got our hands on a beta version of Everest Ultimate, which added preliminary support for the 5970. With that, we could read and log the voltages and temperatures of the various components of the 5970, and properly isolate the issue. From that, we’ve discovered a few interesting things about the 5970. Let’s start things off with the cooler removed from the 5970.
We’ve gone ahead and circled the VRMs in red. There are 9 altogether; 6 on the right side, and 3 near the left side of the card. We aren’t able to track down what each specific VRM is connected to, but we believe that each GPU is attached to 3, each GPU’s RAM is attached to 1, and finally the PLX PCIe bridge is attached to 1. Regardless, pay attention to the location of these VRMs for later discussion. As we previously noted in our 5970 review, when overclocked the card was throttling down in two cases. One was when running OCCT/FurMark, members of AMD’s “power virus†list by virtue of the fact that they put a card under a greater load than AMD believes to be realistically possible. Our 5800 series cards never throttled under these applications, so to see the 5970 throttle here was a bit surprising but not wholly unexpected... |

How can someone with as much rep(if that means anything), with as much posts, and be as helpful and or educated as yourself, make such an idiotic statement?
A failure? Really? So because the VRMs aren't getting cooled, the product is a failure?
lol

I think the time may be coming for triple slot cards.

Can you post some screen shots of you're OC? Not saying we don't believe you but a picture is better than words can describe.

Stressing the crap out of it just to see when it fails isn't really in my gameplan, dunno bout you (OCing it till it cries is another story). Just got my 5970, it runs fine at 850/1200 and 900/1250. Haven't tried higher yet. I do have to say that's it's too dam big (had to take out the cage), and too dam loud (over 30% and it's the loudest thing in the room). Ok so get ssd and some headphones. |

I've been an ATi fan for awhile. (Radeon 9000 series) but this card does not seem like the golden products we just saw with the Radeon HD4000 series.
It seems more like a flashback to Radeon HD2900 cards, with high TDP's, in-effective stock cooling. And an overall failure as a product. (This is why it was re-vised into HD3800's, which were still not as good as nVidia's products.)
All of my statements are logical.
The HD5970 has the same clocks as the HD5850
It's 12" long, which is a problem for most computer cases that a large percentage of folks have (IE, CM590/690 Antec 300/600/900/902/1200, NZXT Tempest/BETA/GAMMA/M59)
It's performance at stock is barely above the HD5850 CrossfireX while having a high power consumption.
HD5870's are $400 and the HD5970's are $625, but with their lackluster performance, there only nice point above HD5850 Crossfire is kinda lost.

They've scrapped the initial design posted on their site and are working on a new version with water flowing over that area. It was getting too hot they way they had it.

, the CM690 does not..

But you invade the 5.25" cage when you do so.
The problem is very few cases are designed to fit a 12" card.
Most are designed to fit 10.5" cards comfortably.

^^ I can probably fit a 15" card in mine, so I'm good for the next 3 gens

H.A.F.'s have something like 14" of space in them.
Many Lian-Li's have 15"+ (like my PC-V2010)
Not many folks own the Armor or Armor JR. anymore though. Atleast from what I've seen around here.
And from what I know sells in the retail market at B&M stores.

Good for us! 395mm comes out to about 15.55in.
I'm holding off on the 5870 and 5970 until proper aftermarket cooling is available. Until then I'll settle for a 5770.

I'm skeptical. 5850X2 might not cut it for games after 8-12 months, especially at my resolution. That's why I went with a 5970, since it can run anything at my resolution and it also gives me the option to buy a second 5970 down the road and still use my sound card. 3x 5850s leaves me no room for anything else and it's slower than 2x 5970s.
