Thermals and noise

As far as thermals and cooling performance goes, the GTX 660 UC’s cooling is slightly better than the GTX 660 SC’s, but when it comes to silence, it didn’t do as well. The GTX 660 UC’s fans can be heard upon starting the game, while the GTX 660 SC remained inaudible almost the entire time.


GTX 660 Ultra Charged


GTX 660 Super Clocked


The Ultra Charged draws slightly more than the Super Clocked, but it’s to be expected with the higher clocks.
