I\'m not so sure ambient temperature plays such a huge role. It would certainly be one factor of many I suppose. So when I am out shooting this winter in -35C, I should see absolutely no noise or hot pixels?
The temperature dependency for recent Canon sensor with very low thermal noise has been measured by R.N. Clark to about 5 degrees C per doubling of exposure time. So if you can get your camera and battery work at that temperature, you will be able to get very low thermal noise. At long exposures though, the heat buildup in the sensor will soon erode much of the benefit.
