PowerColor receives help from Arctic Cooling

Quiet PC aficionados rejoice as PowerColor is expected to release two passive-cooled graphics cards in Q1’2007. The new passive-cooled graphics cards are based on AMD’s ATI Radeon X1950 Pro and X1950XT.  Cooling the ATI Radeon X1950 Pro and X1950XT is a cooler designed by Arctic Cooling. The cooler occupies an adjacent slot below the physical graphics card.

With the Arctic Cooling passive cooler the Radeon X1950 Pro runs approximately 4 degrees Celsius cooler than the stock AMD graphics cooler. This isn’t too surprising as the passive cooler takes advantage of four heat pipes to transfer heat from the 80nm ATI Radeon X1950 Pro GPU. It is unknown how well the passive cooler performs with the ATI Radeon X1950XT though. In addition to the new GPU cooling the new passive-cooled Power Color graphics cards feature passive heatsinks on the memory and voltage regulators as well.

Expect the passive-cooled PowerColor graphics cards to be available early next year. Pricing is of the AMD ATI Radeon X1950 Pro powered variant is expected at $209--$10 higher than the stock cooler equipped model. Pricing of the passive-cooled ATI Radeon X1950XT powered model is unknown at the moment.

fan option?

I wonder if a fan can be mounted to it? Imagine how great that cooler would be for 24/7 HTPCs in cramped cases if you could mount a 120mm fan turning at 5 volts to it.

Not very since it would eat THREE slots then.

Yes. Then it is not passively cooled any more. Sooner or later another haftermarket heat sink will probably introduced that dioes this and occupies (at most) one more slot.

Too bad...

... that the heatsink itself is below the card when mounted. It would have been smart to route the heatpipes so that the heatsink would have been on top of the card. Better convection and the fan at the back of the case would have helped in cooling. Now the heat gets trapped below the cards when this is put inside a case.

Yeah, just like Thermalright HR-03 ...
I believe the HR-03 will be better than this solution from Arctic Cooling.

Huge Cooler

That is one BFC (C=cooler).

passive suddenly got interesting

That makes passive compelling. Well, as long as you don't have a window where you can see its ugly ass.

passive X1950 XT !

X1950 pro is a quiet baby. I have one and a passively cooled version seems to be very possible.

But X1950 XT is a very different story. It is a power hungry beast. It is something like 50% hotter and needs much more power.(Close to x1950 xtx level). I wonder how they can passively cool it.
