While PowerColor announced its new Vortex cooling at COMPUTEX in May, we’ve had to wait until now to see an actual card that uses this innovative cooler. The wait is over, though, as a Vortex-equipped Radeon HD 5770 has now been caught on camera and introduces an adjustable fan that should allow the card to run quieter and cooler than its rivals.

The Vortex cooler design allows the fan to be raised away from the heatsink, providing cooling over a larger surface area. While this expands the two-slot cooler into the adjacent space, PowerColor claim that this technology will “maximize the efficiency of air convection by increasing the space between fan and heat ”. In theory, this will allow for lower temperatures and/or lower fan speeds, which also means less noise.

Unfortunately, there has been no word on how this card will be clocked just yet. However, considering the increased performance of the cooler and the premium that it will inevitably command, we fully expect the Vortex cards to be factory overclocked. PowerColor reports that the Vortex offers similar cooling performance in two-slot mode to the fan on the current 5770 PCS+, which has a 25MHz speed boost for both the core and the RAM. Though it isn’t totally clear from the pictures, the back-plane also looks to be the same as those on the existing PCS+ models, which would imply two DVI-D ports, HDMI and a DisplayPort connection.

From what we can tell, the Vortex cooler is certainly an innovative design, and innovation is always important in differentiating graphics cards. The ability to freely adjust the height of the cooler may also be important to users looking for maximum cooling now but who plan to upgrade to a CrossFire configuration further down the line. There are no details on release date or price as of yet, though reports are suggesting that this model should hit retail within a few weeks. We’ll be sure to post an update as soon as more information becomes available.

Well, surely they can't o/c it more than its 2-slot capability. So I wouldn't expect great clocks out of the box, although it might o/c better, of course.
I am confused how raising the fan can cool the graphics card more?

The heatsink dissipates the heat equally in all directions. Having a fan close will make the heat go away quicker leading to cooler cards. Having the fan further away will make the heat travel a few cm's and then get to the fan before it's cycled away - leading to slight increases in temps.

Powercolor's innovation may be innovative but is it sensible?

As best I can gather, it's less about heat leaving the heatsink, and more about the air blowing over the cooling fins. The air being moved by the fan will travel in a conical shape. So the further away the fan is from the fins, the larger surface area it should cover, and so the more effectively it will cool.

At least, that's the theory.
Technically, BullDogg - if there is a gap between the fan and the heatsink, the air should flow out of the card to the surrounding area, at which point, convection should take over because there is room for the air to flow freely.
It's the same principle as using a shroud with a radiator (watercooling). There's an area of dead space next to the hub of the centre of the fan. Adding a shroud allows air to move, and therefore cool, where previously it couldn't.
