The GTX 970 (and 980) are a bit unique right now. They are using Nvidia's newer Maxwell architecture, and have much reduced power requirements over other high end video cards, and their fans often don't even turn on at all unless under heavy load. The specs page lists the system power requirements at 500w, but the card itself consumes around 145w. Yet their speed is considered current top of the line as far as single GPUs.
I just bought one, and it was a HUGE improvement over my old Radeon 7870 and the fan hasn't run unless I force it to. VERY quiet card with low power consumption and high performance. The 970 is also at a very nice price/performance spot right now. The 980 is faster but also around $200 more. It's not $200 faster, IMO, though...
No, I don't work for Nvidia, it's just a great card right now.
