PowerColor Launches Hellhound RX 7900 XTX and XT GPUs With Triple-Fan Coolers
PowerColor has announced two Radeon RX 7900 XTX and XT graphics cards: Hellhound name. These new cards feature a powerful triple fan cooling solution and appear to slot right below PowerColor’s Red Devil flagship card lineup.
based on either @momomo_us’ Tweet, It looks like PowerColor will use different size coolers for the RX 7900 XTX and RX 7900 XT. The image shows two cards as shown below. The black backplate card is noticeably shorter in length compared to the larger card, and the thickness has been reduced from his three slots to just two slots. I can’t confirm if this smaller card will overall be a dual-slot card, but it will definitely be thinner than the larger card.

If this tweet is correct, the smaller card will inevitably be the Radeon RX 7900 XT and the larger card the RX 7900 XTX. In line with this assumption, PowerColor has only released details of the RX 7900 XTX version, according to their latest blog post. It features a massive triple-slot triple-fan cooler design with a matte black shroud and backplate. This may be an issue and is not the actual color of the card.
An LED lit fan with see-through fan blade design is included with the card. Unfortunately, the color is reportedly not RGB, but we do see options between the Cyan Blue color and the new Amethyst Purple color, new for this generation.
For cooling, the 7900 XTX HellHound connects a set of 8 x 6 nickel-plated copper heatpipes to a 91 x 89 x 2.6mm copper plate to expel heat to the GPU die and memory chips. Attached to the copper heatpipes is a highly unobstructed heatsink that is clearly visible on all sides of the card. PowerColor added a rear slit to the backplate to improve airflow, allowing the air to pass through the card itself.
PowerColor has also upgraded the fan with a new 9-blade design that reportedly cools more than 3C better than the previous generation.
For power delivery, PowerColor has integrated a 14-layer PCB into the RX 7900 XTX HellHound (this is confirmed by PowerColor and not based on @momomo_us’s tweet). This incredibly dense PCB supports a 20-phase power delivery system that, according to PowerColor, reduces signal loss during transmission and helps support high-power-hungry high-end GPUs.
AMD’s RX 7900 XTX and XT are expected to arrive on December 13th. So the full spec sheets for these cards should be available by then or soon after.
