No. That's the DCII cooler. It looks a little something like this.

A better image of the card, for size comparison: it comes with 1000 gallons of fuel oil, a trailer to move it around, and when dug into the ground, it doubles as a nuclear protection bunker.

Ahahahaha, nice! BTW, who uses triple slot cards anyways? Use a dual slot card, and leave the third slot empty so that the blower can suck in air.

^ Also, if that's the size of their single core cards, I can't wait to see their dual cores (7990). What are they gonna be, quad slot cards? Or maybe they only plug into the motherboard via a PCI-e cable extender, and require a separate case?

I raise you one slot.
I see your quad-slot card and raise you an even larger one.

Wow, seriously? Those heat sinks are huge! If you're undervolting these cards, the stock heat exchanger is fine IMHO.

lol, can you say photoshop. even at stock voltage, and overclock, the stock fan is working well for me.

Is this with 3x 7970? or 4x?

Some nice info I lifted from another forum I am on. You can check the 7970 binning with the new version of GPU-Z. Found some interesting info from AMD's own Dave Bauman regarding 7970 binning. With GPU-Z's new ASIC test you can see where your 7970 was binned. If I'm understanding the comments correctly, higher leakage parts require less volts to hit the same speeds as low leakage parts. So AMD lowered the voltage on high leakage chips to narrow the TDP variation amongst all 7970 cards. For low leakage chips they raised the voltage to be able to hit the stock clocks.
Reading through the main thread over at B3D it also looks like there may be a 125mV OVP on the 7970 cards. So the cards with a stock voltage of 1.05V will not be able to run as high a voltage as the cards with 1.175V stock. Makes sense in light of some of the variation we're seeing in overclocking results. Generally the 1.175V cards have no problem running 1.3V while the cards with 1.0250-1.1125V crash at the higher voltage levels (1.25-1.3V).
You can check your ASIC value using GPU-Z 0.5.8. Hopefully we'll see some software tools come out that bypass the OVP.
"Originally Posted by Dave Baumann Actually, it does the opposite! We scale the voltage based on leakage, so the higher leakage parts use lower voltage and the lower leakage parts use a higher voltage - what this is does narrow the entire TDP range of the product.
Everything is qualified at worst case anyway; all the TDP calcs and the fan settings are completed on the wors case for the product range."
"Originally Posted by Dave Baumann No, the nominal voltage is 1.165V, however the higher leakage parts do not need as much voltage to run at those speeds."
"AMD uses the following table to select VID depending on ASIC quality:
up to 2F90 (up to 75% quality) - 1.1750V up to 34D0 (up to 80% quality) - 1.1125V up to 3820 (up to 85% quality) - 1.0500V up to 3A90 (up to 90% quality) - 1.0250V"

interesting info. question is, how do you know if the card is a 'good' one before you buy it?
I bot 4 xfx's from newegg, and they are all the higher voltage model. but if I buy more, will they be the right ones?

might not be an issue for miners tho.. i downvolt mine to 1068 and overclock to 1107. running stable at 2639Mhash (4)
