Gigabyte's VGA Cooling Resembles Car Radiator
Gigabyte's new GV-R577SL-1GD features an impressive, passive cooling system.
Monday GIGABYTE announced the GV-R577SL-1GD, a new AMD Radeon HD 5770 graphics card featuring an internally-developed Ultra Durable VGA technology and Silent-cell cooling design. The latter technology provides a passive approach to cooling using four high-performance heat pipes and two additional fins. Encompassing the entire surface of the PCB, the cooling system resembles a car's radiator grille and looks quite impressive.
"GV-R577SL-1GD is comprised of 4 high-performance heat pipes which are connected to the ultra-huge copper base plate," the company said. "By adopting ultra-huge pure copper base with 4 heat pipes, heat can spreads effectively from hot areas. In addition, GV-R577SL-1GD enhances the overall cooling capability by utilizing the precision process to deliver zero-interval combination between heat pipes and fins. Furthermore, 2 additional fins increase 52.87% surface area to dissipate the GPU temperature."
GIGABYTE said that--when compared to other cards--the Ultra Durable VGA Technology provides 10- to 30-percent more overclocking capabilities, 5- to 10-percent lower GPU temperatures, and "excellent" power efficiency, decreasing power switching loss by 10- to 30-percent. Ultra Durable VGA also features a 2 oz. copper PCB board, Samsung and Hynix memory, Japanese solid capacitor, Ferrite /Metal Core Chokes, and more.
With a core clock of 850 MHz and a memory clock of 4800 MHz, the new GIGABYTE card comes packed with 1GB of GDDR5 memory and support for DirectX 11, Eyefinity, Stream, CrossFireX, and more. Although the product is not yet available on the GIGABYTE website, more information can be obtained here. Unfortunately, pricing and availability was not provided.

Pyroflea That's surprisingly nice looking. I wonder how it performs? With that much surface area I'd imagine it'd work quite well.Reply -

I am not a big fan of passive cooling. I tried with a single 9800gt, it heated up to 121c. Needless to say I went back to active cooling. -
havoc256 I have enough air flow in my case as it is now. passive cooling for the vcard would just reduce the noise created from my box which would be very nice.Reply -
jasonpwns mlopinto2k1Cool but in no way resembles a car radiator. That would require liquid and a fan.Reply
"the cooling system resembles a car's radiator grille"
Not the full radiator, learn to read the article and not just the title.
