Galaxy has introduced a new GeForce GTX 260+ graphics card that occupies only one PCI slot. The card features a slim cooling solution and is only 14.2mm thick. More photos at Expreview, but details about noise and temperature levels are unknown.
After taking apart the heatsink, we found it’s taken advantage of Vapor Chamber technology which is based on the same principles as heatpipe technology. A vapour chamber is composed of three distinct layers: the transportation wick, the vaporisation wick and the condensation wick. A wick is a material that can draw in a liquid by capillary action (think of a sponge absorbing water), but other than that, the names of the layers are pretty self-explanatory. Pure water is heated while in the transportation wick, and as it turns to gas, it moves into the condensation wick. Away from the heat source, the water condenses back into a liquid and travels back to the transportation wick by way of capillary action, ready for the process to begin again.
