Review Gigabyte GV-R685D5-1GD: A Cooler Alternative to the Standard HD 6850

There are the two heatpipes, leading from the heatsink base to the aluminum fins.

Note that the heatsink base is also in direct contact with the memory chips. This should help cooling them down.

A separate aluminum heatsink is installed atop the VRM section.

Itching for some Crossfire action? Connect the card to an identical pair using this connector on the upper part of the graphics card.
