In order to determine maximum load temperatures, we run Furmark's stability test for an extended period of time. The test is carried out with the graphics card operating with automatic fan control but also at 50% fixed fan duty for a fair test.
What an improvement! With the graphics card set to automatic fan control, we reached a maximum temperature of 66*c with a maximum fan speed of 46%. The cooling mechanism was not noticeable over our low RPM 120mm fans, suggesting that the cooler is very quiet indeed. Raising the fan speed to 50% saw a mild temperature drop however a slight whine could be heard from the graphics card. On the basis that our testbed is an open air system, we would gather that under standard conditions its fan would not be noticeable.
The fun didn't end with the temperatures as our GTX 460 proved to be an eager overclocker! Following a number of steady increments, we finally found ourselves with a smoking 864MHz on core, 1728MHz on shaders and 3824MHz on memory. This overclock was verified as stable and will be included in the results that follow.
Do note that GPU-Z currently misreads the Stream Processor count of the GTX 460 as 224. Our sample definitely comes equipped with 336 stream processors.
