The graphics card’s cooling system is a simplified version of the cooler installed on the Palit GeForce GTX 680 Jetstream. It has an aluminum heatsink with heat pipes:

As opposed to the GTX 680 Jetstream, there are only three heat pipes here, each with a diameter of 6 millimeters.


Although cheaper and lighter, the heatsink is still a high-quality thing, its components neatly soldered to each other.

The memory chips are not cooled at all, but it’s okay. The metallic frame around the PCB serves as a support for the cooler’s casing and plastic extension:

A tall aluminum heatsink with a thermal pad is mounted on the power system components.

The two 92mm fans from Power Logic Tech run on fluid dynamic bearings.

We couldn’t find any fans labeled PLA09215S12H on the company’s website, and their stickers only show us their electric properties:

According to our monitoring tools, the speed of the fans can vary from 900 to 2900 RPM.

The cooling system of the Palit GeForce GTX 670 Jetstream turned out to be quite efficient:

Automatic fan mode

Maximum fan speed

In the automatic regulation mode the fans were only 2040 RPM fast and the GPU was 79°C hot. At the maximum speed of 2900 RPM the GPU was 70°C hot. Not as impressive as the Gigabyte, but good enough.

In our overclocking test the Palit card could provide the same GPU frequency growth as the Gigabyte, i.e. +120 MHz, but the resulting clock rate was somewhat higher at 1136 MHz (due to its higher default frequency).

The memory chips did worse than on the Gigabyte and were stable at 6828 MHz (+14%). When overclocked, the GPU grew a mere 2°C hotter, the fans rotating at 2190 RPM.

Thus, the Palit GeForce GTX 670 Jetstream is a well-made product, but the sum of its consumer properties is inferior to that of the above-discussed Gigabyte GeForce GTX 670 Ultra Durable. Now let’s check out the last graphics card we want to show you in this review.
