With a little over a week left until the GeForce GTX 590 becomes official, the very first details about the cooling system employed by Nvidia's dual-GPU monster have been leaked online and reveal that the card features a similar design with that of AMD's Radeon HD 6990.

This means that a fan is placed right in the middle of the plastic shroud covering the card, effectively splitting it into two separate sections, each with its own GF110 graphics core.

The fan will most probably measure 80mm or more in diameter and, according to VR-Zone, the GTX 590 is estimated to reach 297mm in length which makes it similar with the older GeForce GTX 295.

Unlike the GTX 295, however, the plastic shroud can be removed to allow for easier cleaning and the card uses dual vapor chambers to keep the temperatures of the two GF110 cores in check.

Speaking of the GPUs, they are soldered on a 12-layer, 2oz copper printed circuit board and Nvidia uses a 10-phase power supply in order to provide them with the required power.

In addition to detailing the cooling system used by Nvidia for the GTX 590, the slide leaked online also confirms that the company will use a fully fledged version of the GF110 core, so each GPU features 512 stream processors, 64 texturing units and 48 ROP units.

The card also gets 3GB of GDDR5 video buffer that is connected to the two cores via independent 384-bit memory interfaces.

Going with a dual-GPU setup has enabled Nvidia to offer 3D Surround support in the GTX 590 so the card will feature a redesigned rear bracket that packs three dual-link DVI ports as well as a mini-DP output.

The rest of the card's features have yet to be finalized, but the GTX 590 is expected to be released on March 22. (via TechPowerUp)
