The rectangular cover is both a stylish accessory and a mounting frame for a narrow heatsink on power elements. The round heatsink reminding of Zalman solutions only cools the core. In the middle, there's also a big, slow, noiseless fan. |

The quiet cooling system consists of a central cooler and a cover. The former has a cooper base plate and cools both the core and memory chips. |

Traditionally, we monitored temperatures using EVGA Precision (based on RivaTuner).

As you can see, both coolers are very efficient. The extra 20 MHz do not affect card temperature in any way.
