I mean there's no way: AFAIK the relevant Kepler BIOS registers are currently unknown (EDIT: a little update).
At any rate, give a look to some editor, such as Kepler Golden Bios or Kepler Bios Tweaker (even Svet's VBIOS Tuner might work), perhaps they may let you dial down the fans to a lower floor, but YMMV: actually there is no way of knowing this without modding the BIOS, sit down and see if it makes any difference (just for example, usually on the EVGAs it isn't possible to lower their minimum speed).
