The good news is that it’s possible to cool AMD’s flagship Radeon HD 7970 GHz Edition to less than 75 degrees Celsius under full load, maintaining a quiet 32 dB(A) at the same time. The bad news? It'll cost you five expansion slots and more than $100.

Seems to me if you're willing to go 140$ or whatnot to cool your Gfx card, you might be interested in water cooling. 80$ for a Noctua and 100+ for this put you into cheap water cooling territory, and while you could easily spend double or more water cooling, that seems the route to take. Just my two cents.

Why is there an empty slot between the fans and the heatsink? Looks like there could be some space and efficiency savings there. Also, why did you test 120mm fans when 140mm fans are supported?

Where do the additional two fans you haven't tested fit? I guess they might go in the empty slot, but that seems strange to me - why have a fan blowing directly into another fan.

its called push/pull you see it on cpu coolers and watercooling all the time. There are 120mm fans available

@jebby:
This looks just like an empty slot, but it is not enough and the mounting rail will not fit.
You can still mount up 2 fans horizontally or 140mm fans, but that brings no improvement.

Push/pull implies fans on either side of the heatsink - it doesn't look to me like there's enough clearance between the main heatsink and the VRM heatsink.

@FormatC I see what you're saying, but compare the picture on the benchmarks page to these:

http://www.hardwareluxx.de/community/f136/alpenfoehn-peter-821451.html

It looks like the bracket overlaps the heatsink, so the fans are much closer. Maybe it's just the angle.

Edit: They're on different cards, (a 570 and a 480, if my German isn't too bad), my mistake.

This is a HD 7970 problem - the GPU sits higher on the PCB.

< 10mm ;) 

Edit:
I've experimented with different VRM coolers (on some photos you can see a slightly lower silver VRM heatsink) and slim fans but only the big black one (original from EKL) gives you the full performance.

@JebbyC
The Gigabyte thing is in translation (I hope so) :) 

The Windforce 5X @1,25 GHz is (under full load) quieter (!) than a Sapphire Toxic 6GB (1,2 GHz, Tahiti XT2) - thats fact. In a few minutes I will try a showdown between this two cards on 3840 x 3240 (6 cheap monitors, DVI only) and 3 active splitters.

Who wants to bet, can transfer me the money to my private account (which is unfair because I know the result - already) :D

When I see something like this behemoth, it reminds me that we really have a long way to go in terms of technology. I think you can tell silicone/transistor technology is really starting to hit a brick wall when 5 slot aftermarket VGA coolers come onto the scene. For that matter, stock 3 slot products like the ASUS Mars II go without mentioning too.

I think it looks like you may not have that installed correctly. After comparing JebbyC's pictures and the close up of yours, it looks like you skipped a slot between the cards mounting screw plates and the brackets mount. The card is mounted in the first and second slot and the bracket is mounted in the fourth, but it looks as though it should be mounted in the third slot so that the bracket is next to the heatsink and thus bringing the fans much closer to the heatsink as it is in the other pictures.

Like this:

That's great ..... you can get within 1C of the Asus 670 TOP and get almost as much performance !

The $430 Asus 670 TOP totals 1770.8 fps in techpowerup's game test suite (999 fps in Guri3D's) and tops out at 74C under load and two cards in SLI take up 4 slots

This $580 7970 Ghz Edition gets 1763.2 fps in techpowerup's game test suite (952 in Guri3D's) and tops out at 75C under load and this single card takes up 5 slots.

The fan bracket was installed one space too low compared to other reviews I've seen for this cooler. Also, I don't see any memory temps compared here either.

As I read this, this constant thought was nagging in my mind.

------------------------------

The year is 2012. AMD has furiously raced to match the performance lead set by NVidia.

Enter the 7970 GHz edition!

But the noise was a big concern.

Enter the Peter! With its behemoth cooling and tolerable noise, it seemed like a winner despite its exorbitantly high price!

Other simply bought a GTX 680 or regular 7970.

I kind of wonder about the weight, I have an Accelero Extreme on a GTX 460 and worry about the weight of the cooler and fans pulling it down in the slot when in a regular case. I use a block to brace the cards up when installed in regular PC case but at present I have a open case where the MB is flat and the card is sitting upright.

This is not the best idea (hotter and louder), but possible. Don't forget the dead zone in the middle of each fan. You can try slim Scythe Sliptream and rubber do get a distance of min. 5 mm.

Am I the only one the finds this kit (per the review) very amateur, poorly made, expensive, and doesn't even fit correctly?!? I'm sorry, but I would NEVER pay for this piece of junk! 143.6 deg F at 40db!!! That's less than optimal, in fact, that's pretty horrible! That's what... 65-70 deg ABOVE ambient? Jesus what a POS! my 450 GTS stays cooler than that with it's stock POS nvidia reference fan. An acceptable temp would be around 100 deg f ~ 120 deg f under full load.

Wow, I can't see how anyone would like this thing. I mean... just... wow!

Something is wrong with this cooler... Why the fans are positioned so far from the heatsink? It seems like the two parts are designed completely without trying to match them for the ultimate solution.

Big iron with some airflow will always have some effect...

Another thing that really grinds my gears(thank you Family Guy). Why do all these CPU/GPU heatsinks have these heatpipes? Whats the point? I never noticed such high temps. a few years back when if you wanted to overclock, you grabbed a quality beefy, cooper heatsink with a thin sorface and alot of fins. Or if you had to, a huge aluminum heatsink (aka. the Novatech Alpha).

The problem is, when you have such a confined area to work with, heat pipes simply do not work! And just look at that picture, the heat pipes are UPSIDE DOWN! In order for them to function, the MUST remain vertical. This is so the condensed fluid flows back down to the contact area. If they are upside down, the refrigerant just sits there. Besides that, Heatpipes ONLY WORK AT A CERTAIN TEMP. RANGE! What that means is that the CPU/GPU MUST climb to that temp before the refrigerant in the heat pipes start to evaporate.

So.. A think (1/8 inch) slab of copper with a large amount of fins creating a large surface/contact area is by far THE way to go. I'll be happy when all this heat pipe nonsense goes the way of the dodo!

/end rant.
