Coolers

ASUS GeForce GTX 670 DirectCu II TOP

This cooling system is simpler compared with that of GeForce GTX 680. ASUS offers a single heatsink with copper heatpipes. The power transistors are cooled by their own small heatsink, while the memory chips have no cooling at all. ASUS GeForce GTX 670 DirectCu II TOP occupies two slots thanks to the reduced size of the dual-fan plastic cover. That's also the reason why the graphics card gives a little more noise compared with the higher-end counterpart.


Gigabyte GeForce GTX 670 Overclock Edition

The Windforce cooling system used by Gigabyte in the Overclock and Super Overclock series has already proved its efficiency in our tests. The GPU is cooled by two nickel-plated heatsinks interconnected by heatpipes. The cooler base is made of copper. The power transistors have their own small heatsink. Over it all is a plastic cover with three low-profile fans. As a result, the graphics card occupies two slots and the Gigabyte cooling system produces almost no noise.

Palit GeForce GTX 670 JetStream

Palit's cooler is similar but has more fan blades, so the efficiency is better and there's hardly any noise at lower fan speed (~1700 rpm). The power transistors are cooled by their own small heatsink; the memory chips have no special cooling.

Zotac GeForce GTX 670 AMP! Edition

The Zotac's cooling system is similar to the ASUS's but has longer heatpipes and is longer overall. The memory chips and power transistors have their own heatsinks. The fans rotate at over 2000 rpm, so the cooling system produces some noise.

Temperature monitoring results

We measured temperatures using the EVGA PrecisionX utility.

Gigabyte GeForce GTX 670 Overclock Edition


Palit GeForce GTX 670 JetStream


Zotac GeForce GTX 670 AMP! Edition


After working non-stop for 6 hours, all coolers proved quite efficient. The temperatures were below less than 80°C, which is really low such top-level products.
