ATI 6990 pics

is that 120mm fans x2 ?

I wish ati would put on a decent cooler thats literally silent on load.... would save so much headache/hassle and voided warranty issues !
 
I think thats the back of the card in the top pic, so your seeing the spread plate for each core?

To throw it at any Nvidia staff/fanboy in the audience :p.

Joking, yeah it looks about 5970 size. Judging by how the fan is positioned, I'm guessing the heat of one core will come out of the back, while the heat of the other will go into the case? They better have some vapour cooling on this card!

It does look like fan in the middle, you don't often get a blower fan in those situations but more of a normal fan blowing down with the pressure forcing it in each direction, closer to I think the pics of that 560gtx cooler.

Can only hope, blower fans are no where near as effective as a normal fan.

Blower fans are designed for one thing, low airflow but high pressure , which is exactly NOT what you need for limited space gpu cooling, you need airflow and any decent fan simply does not have pressure issues in these situations.
They are loud and a little better with tiny tiny fans, mostly because of design, IE a 30-40mm fan is almost entirely the magnetic part in the middle and almost no blade and do basically nothing.

I've said before, they get into this thing that memory heat spreaders became standard, and people THINK they need them, so most people would buy a set with them than without them, so now they all have them.

People have convinced themselves of 500C temp case increases unless the heat is dumped outside the case and losing their entire cpu overclock, its rubbish, yeah a single 80mm cooled case from 20 years ago would have an issue, any half decent case with 120mm in/out fans has NO issue.

For the record, went from a single exhausting stock cooled 5850 overclocked running at 85C load and not stable past 925Mhz, to third party cooler, all heat inside case, higher voltage 1050Mhz clocks, added a second Asus CU air inside case 5850, and case temps went up about 2C and CPU about 3C, and stable CPU overclock didn't change at all.

Rant over, just blower fans do my head in, its like buying a Ferrari then putting a new front grill on that kills airflow into the engine and overheats and blows up your car :p


The 6990 shouldn't be much bigger than a 5970, similar power usage, 256bit bus, double density memory so same number of chips. Shouldn't need to get much bigger and not quite sure why its taken so long to launch, maybe just waiting for better 69xx supporting drivers with a few more fixes in for a more stable dual gpu card?
 
Well I prefer these coolers compared to the blower ones, they're cooler and quieter ;)

Just had another look at the pictures. On the second one, it seems very blurry and I could be wrong, but looking at the sizes is that a 6-pin and an 8-pin power connector I see? If so looks like they have found a way to keep it under the 300w mark.
 
I prefer radial blowers since they get the heat out of your case instead of just circulating it around. It's especially a good thing when running with multiple cards.

Having a cooler that actually works > radial fans. The amount of heat dumped by cards has very little effect.

I changed my 5870 from a stock cooler (72c load, loudest thing in there) to an aftermarket cooler (45c load, silent) and my CPU increased by 1c.

Effect of the heat depends on case cooling. I use only 2 Nexus 120mm fans @ 700rpm as exhaust (which work at loudest noise level I find any 120mm tolerable). This is good enough to get rid of heat produced by CPU but changing stock to aftermarket on gtx 580 raised the CPU temps by 6-7 degrees. Obviously adding another 250W of heat is not completely OK.
