SPARKLE GeForce GTX 460 768MB
To test temperatures, we run two tests. The first is to find the absolute maximum temperatures that a card would really ever endure, and we do that by firing up FurMark and letting it run for awhile until the temperatures level out. FurMark pushes GPU thermal loads extremely high, and can be considered a worst-case scenario. The second test we do is run looping instances of Crysis Warhead and log the temperatures to find out what a card would typically encounter in normal gaming sessions.
Below are the FurMark "worst case" results:
The heatsink on the GTX 460 produces temperatures almost identical to the Radeon 5850, but more importantly the 460 is 20°C cooler than the GTX 465 at full load. It appears that Nvidia’s architecture for the GTX 460 produces temperatures far better than its larger siblings.
And in our real world test of looping Crysis, the load temperature hit 65°C after 20 minutes. So the gaming temperatures were not only 6°C better than FurMark but the fan ran quiet as well, even under full load, which bodes well for long gaming sessions. The bottom line is that this card keeps the temperatures in check and runs quiet, an attractive combination for gamers.
