It can be controlled by MSI afterburner (which lets look if everything goes well in cooling and lower power frequencies if one believes that the card is involved).
The card (Windforce 3) rotates up to 50% of the speed (70 ° C) ... the cooling fan is great!
Since drivers nvidia 337, the GTX 770 card is stable.
Tip: do NOT activate the vertical synchronization (Vsync) ... it consumes too much CPU and planted the games (and no use for beauty or accuracy 1980x1080 ultra fashionable in recent games)
Cons: I had to cut my turn, one of the sheets of the hard drive carrier so that the card returned ... she's super-long! but doing so does not alter the tower or does not pose a problem (using a bolt cutter to DIY store).
