Expreview found some photos of the upcoming dual-GPU ATI Radeon HD 5970 graphics card. This new part is 13.5" long, making it one of the longest consumer graphics cards ever, and the cooling solution is reportedly quite noisy.
Radeon HD 5970 features a very long PCB which measures 13.5 inch (i.e.34.29cm), making it to be the longest ever. The reviewer actually had some problems fitting it into a full-sized tower case like the Antec 1200. According to them, the fan worked at 4700RPM under load, not unexpectedly, too much noise as well.
