ASUS GTX 460 TOP 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:
Wow, now that’s a sight for sore eyes. The heatsink on the GTX 460 TOP utterly spanks the competition in terms of temperatures. Look at that load temperature, only 61°C, a full 30°C cooler than the GTX 465! It would seem we can conclude two critical things here: first, Nvidia’s architecture for the GTX 460 produces temperatures nowhere near its 480/465 siblings; and second, the ASUS heatsink is doing an outstanding job of keeping low temperatures while under full load in a worst-case scenario of FurMark.
And in our real world test of looping Crysis, the load temperature hit only 56°C after 20 minutes. Outstanding. So the gaming temperatures were not only 4°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 runs impressively cool and quiet, an attractive combination that is often hard to come by these days.
