Underneath the fan is a large heatsink with three heatpipes, and the plastic hood that holds the fans in place covers the entire card.
The cooler houses two large 8cm diameter fans connected to the 4-pin connector via one cable, and rpm regulation is a breeze. The cooler seems a bit larger than the reference one and makes the card look longer, but it’s exactly two slots wide and about 27 centimeters long, just like the reference card. Unlike the reference card with dual slot cooling and one fan, Gainward uses two fans in order to maximize cooling efficiency and provide silent operation. Gainward's clocks are a bit higher compared to reference's 633MHz core, 1134MHz memory and 1404MHz shaders. The GPU runs at 648MHz, the memory at 1185MHz and the shaders at 1420MHz. We are looking at a non-reference GTX 275 card that comes with a completely different PCB and cooling. Out today's guest is Gainward's GTX 275 Golden Sample. It differs from GTX 260 and GTX 285 only in some characteristics, such as the number of active execution units and clock rates. GTX 275 should perform on par with the discontinued GTX 280. Speed-wise, we'd put the GTX 275 closer to the GTX 285 than the GTX 260, and a little bit of overclocking will help you match its results to the ones scored by the much pricier GTX 285. It is positioned slightly cheaper compared to the HD 4890 and these two cards promised to be fierce competitors. If you are planning to buy a gaming graphics card, it's no secret that Geforce GTX 275 is still one of the best picks. In order to ruin AMD's party, Nvidia announced this card on the same day when AMD announced Radeon HD 4890. Review: Non-reference cooling and a factory overclock
