Yeston seems to be preparing a Custom Designed Radeon HD7970 which would feature a large heatsink covering atleast three expansion slots. Yeston was also working on a cheaper PCB design for HD7970 which it would use in the new Graphic Card.

Yeston’s Radeon HD7970 would feature a custom designed heatsink which would cover three expansion slots which means only two of the same cards can be Crossfire’d together. The heatsink consist of a large aluminium fin array block which has 6 copper heatpipes running through it to transfer heat, The GPU Core contact base is also made of copper. Heat is blown out of the GPU through two 120mm fans, One on the left side is PWM Controlled to ensure temperature regulation on the GPU Core and Memory while the Right side fan is kept at a constant speed to provide airflow to the power area.

If you look closely, A backplate can also be spotted which is held by four metallic rods. Display outputs would include Dual-DVI and 2 x Mini Display Ports. Although its unknown what clock frequencies the card would run at but Yeston tells that a Gamer Edition Radeon HD7970 would also be available soon. Release Date and Pricing aren’t known yet.

Shouldn't technology be heading towards the same cooling potential but in single slot solutions (aside water cooling). This 3 slot malarkey is getting out of control.
 
Hope they include a monster length crossfire connector to reach around that beast.

Have to agree with this. They should be moving cooling tech into smaller but just as efficient. At the moment it just seems to be 'look at the size of our cooler! We're awesome!'

Unfortunately, while there is still plenty of room for improvement in every aspect of GPU design, the physics of removing waste heat is not so easy to innovate in. There's only so much that can be done to remove 250W+ of heat energy from an add-in card that's trapped in a closed box.

It simply isn't realistic to expect to be able to cool a 250W card using a single-slot air cooler. There just isn't enough room to dissipate heat, without using massive airflow - certainly not without dumping heat back into the case as many third-party coolers do. (...this is a more efficient cooling system as it allows for larger, quieter fans with better airflow, but it's not realistic for retail cards because not everyone has the case airflow to remove the heat that's dumped back inside).
 
Im a big fan of things like this.I thought the EVGA classified 580 with the bigger fan was nice but really its not enough and they could have done a lot more.

I want them to hire me :P

The card looks amazing but ugly as well.They need to make it look like the Asus direct CU II where its all enclosed in a nice black plastic frame and a backplate so there are no signs of inner pcb or heatsink.

And the fan blades look a little thin.Why can they not take a look at those hairdryer delta fans.There is enough room and it would push some monsterous CMF and probably still be quiet as the fans are just so big they dont need a lot of RPM.

Hopefully someone does a proper Keplar version.Triple slot GK 112 with 512bit ring bus and 3GB vram.

:eek::eek::eek:
 
Why do we need great cooling in single slot? Its not needed, and considering 98% of all gpu's end up in normal pc's with no xfire and few if any other pci-e/pci cards to speak of, most of them could easily be absolutely silent, higher clocked, cooler running with lower failure rate cards if they came with BIGGER coolers, not smaller.

There is no need to ever hear your gpu fan with a big enough heatsink.

As for efficiency, its simply physics, really really simple physics, airflow, surface area, a little pressure thrown in. A tiny heatsink with a tiny fan, the only way to increase the cooling capacity is increase the airflow, which means fan speed which means more noise.

A huge portion of the noise of a HIGH quality fan, IS the airflow. Low airflow and big surface area are the key, high airflow increases noise and over a well designed heatsink you gain a lot of noise for very little increased cooling. high airflow isn't a design goal, lowest airflow and lowest noise possible should be the design goal for any heatsink(for any computer that is in earshot of people).
 
Shame it wil never see the lightb of day outside of china buf maybe thats a good thing. read the story again their using a cheaper pcb so overclocking will be limited so what you gain with the cooler you lose with the pcb.
 
Cheaper PCB doesn't always mean worse overclocking. A company can use the same PCB and lower specced VRM's and cause worse overclocking, another company can make its own PCB, get it done cheaper, and have it work better.

Either way the biggest issue with overclocking ANY graphics card is heat and not being able to up voltage due to heat, better cooling on just about any card lets you overclock further.

Hahahaha I think you've gotten a little caught up in the microelectronics revolution there. While massive leaps in that field of engineering are commonplace it doesn't carry through to thermodynamics/fluid mechanics which are ancient and well-established, with all the most important results having been made long ago.
 
One thing that bothers me though is that they've used a heatsink array more suitable for 80/92mm fans rather than a 120mm one. It seems that all they've done is grabbed an already made heatsink that looks similar to one or two already on market (Prolimatech, Arctic etc) and slapped two oversized fans to it. Now that's fine I suppose but what a waste of airflow. A third of the airflow will pass over nothing and not really help with heat transfer. So the heatsink could be quite a bit larger and therefore much better at transferring heat, or it could be thinner and allow for a deeper fan, or for it to fit more comfortably in 3 slots.

So in my opinion it's a fail.
