Now, the same test, but the frequencies of the card are set to 400/1100MHz, i.e. to the frequencies of the GeForce 6800 Ultra:

Overclocked to the frequencies of the GeForce 6800 GT, the card became just a little hotter: 3°C more of the GPU temperature and 2°C of the PCB temperature. The cooling system evidently does its job right even when the fans are working at half of their maximum speed.

Now, let’s try the card at the maximum clock rates (430/1200MHz):

The temperatures have grown by a single degree, not more. So, the temperatures of the graphics card have only grown by 4°C at worst during overclocking! That’s an excellent result – you shouldn’t have any overheat-related problems with the Gainward PowerPack! Ultra/2400 Golden Sample.
