Good news for Small Form factor owners, these cards are rather cool during their operations and the heatsink fan occupy only a single slot unlike the GeForce 6800Ultra that take up two slots. Since the fan speed varies according to the temperature of the core, most of the time the fan was spinning at low rpm. Although the fan is huge, it is still less noisy than the blower fan found in GeForce 6800Ultra. This fan will also light up in blue during operation, a visual treat for casing with windows.
